Google’s Threat Intelligence Group has uncovered a new wave of cyberattacks where hackers are using public blockchains to host and distribute malicious code. This alarming trend transforms one of the world’s most secure and tamper-resistant technologies into a stealthy channel for cybercrime. According to Google’s latest report, several advanced threat actors, including one group suspected of operating on behalf of North Korea have begun embedding harmful code into smart contracts on major blockchain platforms such as Ethereum and the BNB Smart Chain. The technique, known as “EtherHiding,” allows attackers to conceal malware within the blockchain itself, creating a nearly untraceable and permanent delivery system. Smart contracts were originally designed to enable transparent and trustworthy transactions without intermediaries. However, attackers are now exploiting their immutability to host malware that cannot be deleted or blocked. Once malicious code is written into a blockchain contract, it becomes permanently accessible to anyone who knows how to retrieve it. This innovation replaces the need for traditional “bulletproof hosting” services, offshore servers that cybercriminals once used to evade law enforcement. By using blockchain networks instead, hackers can distribute malicious software at a fraction of the cost, often paying less than two dollars per contract update. The decentralized nature of these systems eliminates any single point of failure, meaning there is no authority capable of taking down the malicious data. Even blockchain’s anonymity features benefit attackers, as retrieving code from smart contracts leaves no identifiable trace in transaction logs. How the Attacks Unfold Google researchers observed that hackers often begin their campaigns with social engineering tactics targeting software developers. Pretending to be recruiters, they send job offers that require the victims to complete “technical tasks.” The provided test files secretly install the initial stage of malware. Once the system is compromised, additional malicious components are fetched directly from smart contracts stored on Ethereum or BNB Smart Chain. This multi-layered strategy enables attackers to modify or update their payloads anytime without being detected by conventional cybersecurity tools. Among the identified actors, UNC5342, a North Korea-linked hacking collective, uses a downloader called JadeSnow to pull secondary payloads hidden within blockchain contracts. In several incidents, the group switched between Ethereum and BNB Smart Chain mid-operation; a move possibly motivated by lower transaction fees or operational segmentation. Another financially driven group, UNC5142, has reportedly adopted the same approach, signaling a broader trend among sophisticated threat actors. The findings stress upon how cybercriminals are reimagining blockchain’s purpose. A tool built for transparency and trust is now being reshaped into an indestructible infrastructure for malware delivery. Analysts also note that North Korea’s cyber operations have become more advanced in recent years. Blockchain research firm Elliptic estimated earlier this month that North Korean-linked hackers have collectively stolen over $2 billion in digital assets since early 2025. Security experts warn that as blockchain adoption expands, defenders must develop new strategies to monitor and counter such decentralized threats. Traditional takedown mechanisms will no longer suffice when malicious data resides within a public, unchangeable ledger.

McKesson Corporation is investigating a cybersecurity incident involving unauthorized access to third-party applications and data exfiltration, while the ShinyHunters extortion group claims it stole approximately 284 million patient-related records from the healthcare and pharmaceutical distribution company. McKesson said it discovered the incident on August 25 and immediately activated its incident-response procedures. The company has brought in external cybersecurity specialists to assist with the investigation, which it said remains in its early stages. In a filing with the U.S. Securities and Exchange Commission, McKesson said it has not determined that the incident is material or that it has had, or is reasonably likely to have, a material impact on its financial condition or operations. The company confirmed in a separate customer notice that the incident involved unauthorized access to third-party applications and the exfiltration of data. McKesson has not identified the affected applications, disclosed how the attackers obtained access, or confirmed what information was taken. Customers could also experience intermittent service degradation believed to be related to the incident. McKesson said it was not proactively disconnecting systems within its environment. ShinyHunters claims employee accounts were compromised ShinyHunters claims it obtained initial access through voice-phishing, or vishing, attacks targeting multiple McKesson employees. According to the group, the attacks resulted in the compromise of several employee Okta single sign-on accounts. Those accounts were allegedly used to access McKesson's Salesforce and Snowflake environments. The group claims it obtained extensive access to Salesforce, including support cases, and extracted a larger volume of patient-related information from Snowflake. ShinyHunters alleges that approximately 1 TB of data was removed over four days, from August 21 through August 25. The group has claimed that the Snowflake data contained roughly 284 million patient-related records. However, it later clarified that this figure represents individual database records or lines, rather than 284 million unique patients. ShinyHunters also said it has not completed its analysis of the stolen material and therefore cannot determine how many individuals are represented in the dataset. The alleged information includes names, addresses, dates of birth, Social Security numbers, patient IDs, phone numbers, email addresses, Medicaid numbers and medical record numbers. The group also claims the data contains medication and allergy information, illnesses, disabilities, appointments, physician details, prescriptions and medication shipments. Other allegedly stolen material includes information relating to deceased and terminally ill patients, invoices, employee data, Salesforce records, internal communications, and information about healthcare providers and clinics using McKesson's services. McKesson has not confirmed any of these specific data categories, and the claims about the stolen information have not been independently verified. McKesson domain follows ShinyHunters pattern The alleged campaign also involved the "mckesson[.]claims" domain. The domain follows a pattern previously associated with ShinyHunters activity. ReliaQuest has documented campaigns in which domains using a targeted company's name or abbreviation alongside the ".claims" top-level domain were used to impersonate help-desk or IT personnel. The technique is particularly relevant to the alleged McKesson attack because social engineering is increasingly being used to obtain legitimate employee credentials rather than deploying malware directly against an organization's infrastructure. ReliaQuest recently documented an attempted attack against its own employees in which an attacker used a lookalike domain, impersonated a security employee and attempted to persuade staff to authenticate through a fraudulent SSO page. Additional security controls prevented the attacker from reaching business applications or customer information. Health-ISAC has also warned healthcare organizations about an increase in ShinyHunters activity involving social engineering, identity compromise and subsequent access to cloud and SaaS platforms. Its analysis describes an attack chain in which threat actors use vishing or help-desk manipulation to compromise identity-provider accounts before moving into connected services. Such access can allow attackers to retrieve large volumes of information through legitimate cloud applications. Research from the Retail & Hospitality ISAC has further linked ShinyHunters to the abuse of OAuth relationships and SaaS applications. By operating through legitimate identities or application permissions, attackers can make unauthorized activity more difficult to distinguish from ordinary cloud usage. The alleged McKesson intrusion has not been independently confirmed to have followed this entire sequence, but the claimed compromise of employee SSO accounts followed by access to Salesforce and Snowflake is consistent with the identity-focused tactics researchers have been tracking. $55 million ransom demand claimed ShinyHunters claims it contacted McKesson after completing the alleged data theft on August 25 and demanded $55,236,150 in ransom, giving the company 72 hours to respond. The group claims McKesson did not negotiate over the demand. McKesson has not publicly confirmed the ransom demand or its alleged communications with the extortion group. The incident comes as ShinyHunters-linked attacks continue to target healthcare and health-technology organizations. Recent organizations reportedly targeted by the group include Medtronic, DentaQuest, iRhythm, One Medical and AdaptHealth. For McKesson, the immediate question remains the actual scope of the incident. The company has confirmed unauthorized access to third-party applications and data exfiltration, but has not established which systems were affected, what information was taken or how many individuals may ultimately be impacted. Until McKesson completes its investigation, the 284 million-record figure and the specific claims surrounding the alleged Snowflake and Salesforce compromise remain unverified.

 North Korean hackers have been targeting the infrastructure and cryptocurrency wallets worldwide. Greek security expert Vangelis Stykas identified 1,640 organizations across 57 countries hit by the attack. His investigation, which gained unauthorized access to the networks run by North Korean hackers, took about 22 months.  At the Black Hat conference in Las Vegas, Stykas spoke about the attacks, mentioning that around 700 to 800 companies out of 1,640 had fallen victim to “truly malicious” intrusion. In some cases, the servers and AWS accounts were compromised at the root level by state-sponsored groups. Stykas did not disclose how he managed to infiltrate the North Korean hacking groups. He noted that his computer might have been infected with the group’s malware since their computers were infected.  The security analyst had access to Slack and Discord accounts controlled by the hackers and gathered five terabytes of data. Lazarus Group complex, one of the North Korean state-sponsored hacking groups, has been using encrypted messaging services like Telegram and Signal to coordinate crypto heists and money laundering schemes. According to the report by Chainalysis, which monitors illicit crypto transactions, North Korean hackers have generated more than $2.02 billion in 2025, a 51 percent increase from the previous year.  Their cumulative cryptocurrency theft since 2017 reached about $6.75 billion in value through crypto heists. Moreover, 76% of crypto heists worldwide occurred in the first four months of 2026, with North Korean-sponsored groups being the masterminds behind these crimes. The groups are also changing their tactics, shifting from compromised encryption keys to social engineering to infiltrate new crypto exchanges. Stykas added that toward the end of 2024, attackers primarily used social engineering to convince victims to install malicious software on their computers by posing as recruiters offering high-paying IT jobs.  The software would allow hackers to access the victims’ computers under the guise of testing their skills. The list of companies targeted by North Korean hackers includes Chinese smartphone manufacturer Oppo, Boston’s Children Hospital, tech firms in Japan, Italy’s judicial organizations, and Belgium’s Flemish government. Several of the organizations, including Flemish government agencies and Boston’s Children Hospital, noted that the breach originated from third-party contractors, and the damage was minimal.  Moreover, Stykas added that many of his warnings went unheeded by the organizations that had fallen victim to the attacks. His research revealed that many organizations are using third-party contractors and service providers that operate as subcontractors for different firms. A single compromised third-party organization can lead to a security breach of multiple organizations.  North Korean hackers not only target crypto wallets but also use their IT expertise to infiltrate organizations and exfiltrate data. Experts believe that North Korea continues to fund its nuclear program from the proceeds of these crimes.  Moreover, hackers pose as legitimate IT professionals offering their services on job boards, eventually getting hired and transferring the earnings to North Korean banks. Authorities believe North Korean hackers’ activities are designed to circumvent sanctions imposed on the country.  According to experts, the infiltration of crypto exchanges, technology companies, and financial organizations will enable North Korea to bypass sanctions while funding its military expansion and nuclear program. Andariel hacker group, which targets defense and nuclear-related organizations, was dismantled by security agencies in 2024.

  Phishing is no longer limited to technically skilled criminals building fraudulent campaigns from scratch. Through phishing-as-a-service (PhaaS), attackers can rent ready-made infrastructure and tools that allow them to impersonate trusted organisations, harvest credentials and target victims at scale. Phishing attacks use social engineering to persuade victims to surrender sensitive information. The lure can arrive through an email, text message, phone call, QR code, fake website or malicious application, often impersonating a bank, employer, delivery company or another trusted entity. Stolen passwords, financial details and authentication information can then be used for account takeovers, fraud, identity theft or further attacks. The emergence of PhaaS has made this process considerably easier. PhaaS lowers the barrier for cybercriminals Instead of developing an operation independently, criminals can purchase packages containing fake login pages, legitimate-looking email templates, phishing-site hosting, target lists and setup instructions. Some providers also offer technical assistance and campaign-management capabilities. The model mirrors legitimate software-as-a-service businesses, except the product is designed to facilitate cybercrime. Microsoft describes the wider cybercrime-as-a-service economy as increasingly commercialised, with specialised services allowing criminals to outsource different parts of an attack. This creates a multiplier effect. Criminals with limited technical expertise can deploy infrastructure developed by more experienced operators, allowing phishing campaigns to reach far more people than a small group of skilled attackers could target independently. The threat is therefore not simply that individual phishing messages are becoming more convincing. It is that the number of people capable of launching campaigns is increasing. PhaaS is evolving beyond password theft Modern phishing services can also target authentication sessions rather than simply collecting usernames and passwords. Adversary-in-the-middle attacks, for example, place attacker-controlled infrastructure between a victim and the legitimate authentication service. The victim may still complete the expected login and MFA process, while the attacker attempts to capture authentication information or session tokens that can later be used to access the account. Microsoft has documented phishing campaigns in which attackers captured tokens generated during legitimate authentication, demonstrating why stolen credentials are not the only concern. The scale of these operations was illustrated in March 2026 when authorities disrupted Tycoon 2FA, a PhaaS platform that facilitated phishing attacks against nearly 100,000 organisations. Europol said the service generated tens of millions of phishing emails each month and, by mid-2025, accounted for roughly 62% of phishing attempts blocked by Microsoft. AI is making familiar warning signs less reliable Artificial intelligence is adding another advantage for attackers by making social-engineering content faster and easier to produce. Poor grammar and spelling mistakes were once common indicators of phishing. Generative AI can now produce polished messages in seconds, allowing criminals to create more convincing communications and adapt them to different targets. Microsoft has reported that cybercriminals are using AI to automate phishing and generate synthetic content. Users therefore need to focus less on whether a message is grammatically correct and more on what it is asking them to do. Unexpected requests for passwords, payment information, verification codes or urgent account actions should be independently verified. Links should be inspected before opening, while sensitive websites are safer to access directly rather than through unsolicited messages. Unexpected attachments should also be treated cautiously. Defence must account for stolen credentials Basic security practices remain important, but organisations should also assume that phishing attempts will occasionally succeed. Unique passwords stored in a password manager can limit the damage caused by credential reuse, while multifactor authentication adds another layer of protection. However, phishing-resistant authentication such as passkeys and FIDO-based methods provides stronger protection against attacks designed to capture authentication information. Microsoft says phishing-resistant MFA can stop more than 99% of attacks of this type even when attackers possess the password. Organisations should also monitor unusual account activity, remove unnecessary accounts and minimise user privileges so that compromised credentials do not automatically provide extensive access. PhaaS has therefore changed more than the technical mechanics of phishing. It has changed who can conduct these attacks and how easily they can be scaled. As criminal infrastructure becomes increasingly commercialised and AI reduces the effort required to produce convincing lures, defending against phishing can no longer depend solely on recognising suspicious messages. The stronger strategy is to combine user awareness with authentication and access controls designed to limit what happens when a phishing attempt succeeds.

  Hackers have stolen around 607,000 records from England's Department for Education (DfE) after compromising systems used to handle enquiries and administer international education funding. The department confirmed the cyber incident after attackers accessed data held through the DfE's online help desk and the portal supporting the Turing Scheme. The compromised information includes telephone numbers and email addresses associated with individuals and organisations that had interacted with the department. Reports have also identified names and job titles among the exposed information, including details belonging to school leaders, university staff and government officials. However, the DfE said the affected information was limited to customer-service contact details and that bank details and other sensitive information were not accessed. The department has stressed that the figure of 607,000 refers to records rather than the number of individuals affected. A single person or organisation may therefore account for multiple records across the affected systems. Social Engineering Reportedly Used Against DfE Helpdesk The breach reportedly involved a social-engineering attack against an external-facing DfE helpdesk used by education-sector organisations and local authorities. Computer Weekly reported that the attackers targeted the department's helpdesk and obtained more than 600,000 records containing personally identifiable information, while the affected systems were taken offline as the department investigated the incident. The Times also reported that it had verified the authenticity of some of the leaked information. The incident illustrates why customer-facing systems can represent an attractive target. Helpdesks routinely process legitimate requests from large numbers of users and may contain historical enquiries and account-linked information. If an attacker can manipulate a support process or gain access to an account with sufficient privileges, information held outside an organisation's core systems can become exposed. The DfE has not publicly disclosed a complete technical account of how the attackers gained access or which specific vulnerability was exploited. It would therefore be premature to attribute the breach to a particular software flaw or compromised credential without further evidence. A group calling itself ExfilSquad has claimed responsibility for the attack and has reportedly published or advertised stolen information online. The group's claims should be treated as claims by the alleged attackers, although multiple reports have examined samples of the data and reported that some information was authentic. DfE Moves to Contain the Incident The DfE said it acted quickly after identifying the incident and has been working with the National Cyber Security Centre (NCSC) and the National Crime Agency (NCA) to establish what happened and assess the impact. The department has also referred itself to the Information Commissioner's Office (ICO), the UK's data protection regulator. A DfE spokesperson said the department had "robust processes" to protect information and had taken swift action to contain the incident. The department maintained that the information involved was restricted to customer-service contact details and that no other data had been accessed. The NCA separately confirmed that it was aware of the incident and was working with partners to understand the circumstances and its impact. The DfE has also temporarily affected the operation of the services involved while remediation work is carried out. Reports said the department switched to telephone support while the affected systems were being addressed, with normal operation expected to resume after the disruption. The department has assessed the data-protection risk to affected individuals as low. However, the exposure of professional contact information can still create opportunities for follow-on attacks, particularly phishing and impersonation campaigns that use legitimate names, job titles, organisations or previous interactions to make fraudulent communications appear credible. Education Sector Continues Being Prime Target The DfE breach comes as education organisations across the UK continue to report high levels of cyber incidents. The latest UK government's Cyber Security Breaches Survey 2025/26 found that 49% of primary schools, 73% of secondary schools, 88% of further-education colleges and 98% of higher-education institutions had identified a breach or cyber attack during the previous 12 months. The comparable figure for UK businesses was 43%. The frequency of attacks was also high among colleges and universities. Around 24% of further-education colleges and 29% of higher-education institutions reported experiencing a breach or attack at least weekly. The survey found that 14% of primary schools and 20% of secondary schools experienced attacks at least weekly. Phishing remained the dominant threat. Among institutions that had identified a breach or attack, 90% of primary schools and 96% of secondary schools reported phishing incidents. The same figure was 96% for further- and higher-education institutions combined. The government survey also identified higher levels of other attack types across further and higher education. These included impersonation, reported by 79% of affected further- and higher-education institutions, viruses, spyware or malware at 51%, and denial-of-service attacks at 49%. Unauthorised access to files or networks by staff was reported by 29%, while 23% reported unauthorised access by students. The consequences extend beyond the initial compromise. Almost half, or 49%, of further- and higher-education institutions that identified a breach or attack reported at least one negative outcome for their systems. Compromised accounts or systems being used for illicit purposes accounted for 23%, while 16% reported websites, applications or online services being slowed or taken down and 14% reported losing access to files or networks. Contact Data Can Become a Launchpad for Further Attacks Although the DfE maintains that highly sensitive information was not accessed, the exposed records still have security implications. Names, job titles, work email addresses and telephone numbers can provide attackers with the information required to make subsequent phishing or impersonation attempts appear legitimate. A message addressed to a known employee, referencing their role or organisation, can be considerably more convincing than an unsolicited generic email. This risk is particularly relevant in education, where senior school leaders, university staff and government officials may have access to wider organisational systems or sensitive information. The latest government survey indicates that impersonation is already a recurring problem in the sector. Among further- and higher-education institutions that identified breaches or attacks, 79% reported attempts involving people impersonating their organisation or staff. The DfE incident therefore demonstrates that the consequences of a data breach do not necessarily end when the initial intrusion is contained. Exposed contact information can potentially become useful in later social-engineering campaigns, while disruption to public-facing services can continue during investigation and recovery. For organisations handling large volumes of education-sector data, securing customer support infrastructure is therefore part of protecting the wider attack surface. Access controls, strong identity verification, monitoring and rapid incident response can limit how far an attacker can move after compromising an externally accessible service. The DfE investigation remains ongoing, with the department working alongside the NCSC and NCA and having notified the ICO. The full circumstances of the intrusion, including how the attackers gained access and the precise extent of the exposed information, are expected to become clearer as the investigation progresses.

 Unexpectedly, the ENS gateway known as eth.limo revealed a DNS hijack stemming from a social engineering scheme aimed at EasyDNS, its domain provider. Though settings shifted temporarily under unauthorized access, safeguards held firm throughout. Protection layers blocked harm, keeping user activity untouched during the episode. Compromise occurred at the registrar level - yet defenses prevented escalation beyond domain redirection. Hours after the incident started, a person pretending to be part of the eth.limo group tricked EasyDNS support into starting an account reset.  Because of that mistaken trust, the intruder gained entry and altered where the domain pointed, shifting it first through servers at Cloudflare, then moving again toward Namecheap systems. Right away, automatic warnings went off once those shifts happened, which gave the real eth.limo members time to react fast. Their quick actions reversed the breach soon afterward. A single point of failure in eth.limo allowed it to act like a bridge, routing requests from regular browsers to data hosted on networks such as IPFS, Arweave, and Swarm. Because its DNS setup uses wildcards, countless .eth addresses rely on the same infrastructure - making them vulnerable when one part fails.  Traffic meant for legitimate decentralized sites might instead flow toward harmful servers under attacker control. Notable resources, even those tied to figures like Vitalik Buterin, faced potential exposure should deception tactics have taken hold. Stopping the damage came down to DNS Security Extensions - called DNSSEC by many. Not through speed, but through verification: it checks DNS replies with digital signatures. Without access to the correct private keys, the hacker's fake entries could not pass these tests. Because validation failed, devices refused the corrupted data, showing failures rather than loading harmful pages.  Though eth.limo and EasyDNS saw interference, they noted minimal reach due to this layer. To date, no individuals have faced consequences from the attempt. Surprisingly, EasyDNS spoke out after the event, calling it their initial customer-targeted social engineering success in almost thirty years. Following this, improvements to internal procedures are underway. Instead of old methods, eth.limo will shift to a tighter system - one without recovery pathways. That change aims to block repeat incidents.  Over time, weaker entry points may fade. Security evolves differently now. Most recent cases show similar patterns across decentralized services. Though blockchains themselves stay distributed and protected, the websites people actually visit run on standard domain setups. These entry points open doors hackers are now using more frequently. Instead of breaking encryption, they shift traffic by manipulating DNS records. Users get sent elsewhere without noticing - sometimes losing assets quickly. Security layers matter more than ever, shown clearly by what happened with eth.limo.  Even when human manipulation tricks succeed, safeguards such as DNSSEC often stop further damage. Because digital dangers keep changing shape, companies - especially in cryptocurrency - now pay closer attention to protecting not just blockchain networks but also the traditional services people rely on to reach them.

  A cybercrime network known as Scattered LAPSUS$ Hunters, or SLH, is offering financial rewards ranging from $500 to $1,000 per call to recruit women for voice phishing operations targeting corporate IT help desks. The development was detailed in a threat intelligence brief published by Dataminr. According to the firm, recruits are provided with prepared scripts and paid upfront for participating in impersonation calls designed to trick help desk staff into granting account access. Analysts assess that specifically seeking female callers may be an intentional tactic to improve credibility and increase the likelihood of successful password or multi-factor authentication resets. SLH is described as a high-profile cybercrime alliance associated with actors tied to LAPSUS$, Scattered Spider, and ShinyHunters. The group has previously demonstrated the ability to bypass multi-factor authentication using methods such as MFA prompt flooding and SIM swapping. A core component of its intrusion strategy involves directly contacting help desks or call centers while posing as legitimate employees. Attackers attempt to persuade support staff to reset credentials or deploy remote monitoring and management software that enables persistent remote access. Once inside a network, Scattered Spider operators have been observed moving laterally into virtualized infrastructure, elevating privileges, and extracting sensitive enterprise information. In some incidents, the intrusion progressed to ransomware deployment. To blend into legitimate traffic and evade detection, the actors routinely leverage trusted infrastructure and residential proxy services, including Luminati and OxyLabs. They have also used tunneling tools such as Ngrok, Teleport, and Pinggy, along with file-sharing platforms like file.io, gofile.io, mega.nz, and transfer.sh to transfer stolen data. Earlier this month, Palo Alto Networks Unit 42, which tracks Scattered Spider under the alias Muddled Libra, described the actor as highly adept at manipulating human psychology. In one September 2025 investigation, attackers reportedly obtained privileged credentials through a help desk call, created a virtual machine, conducted Active Directory enumeration, and attempted to extract Microsoft Outlook mailbox data along with information downloaded from a Snowflake database. Unit 42 also documented the group’s extensive targeting of Microsoft Azure environments through the Graph API to gain access to cloud resources. Tools such as ADRecon have been deployed to map directory structures and identify valuable assets. Dataminr characterized the recruitment campaign as a calculated evolution in tactics, suggesting that the use of female voices may help bypass preconceived attacker profiles that help desk staff are trained to recognize. Update: Shift Toward Branded Subdomain Impersonation and Mobile-Focused Phishing In a follow-up assessment dated February 26, 2026, ReliaQuest reported observing ShinyHunters potentially transitioning to branded subdomain impersonation paired with live adversary-in-the-middle phishing and phone-guided social engineering. Observed domains followed formats resembling “organization.sso-verify.com.” Researchers indicated that the group may be reusing previously exposed software-as-a-service records to craft convincing scenarios and identify the most effective internal targets. This method can enable rapid identity compromise and SaaS access through a single valid single sign-on session or help desk reset, without deploying custom malware. ReliaQuest assessed that moving away from newly registered lookalike domains could help evade traditional domain-age detection controls. Simultaneously, mobile-oriented phishing lures may reduce visibility within enterprise network monitoring systems. The firm also noted signs of outsourced criminal labor to scale phone, email, and SMS outreach. While the impersonation style resembles earlier Scattered Spider techniques, ReliaQuest attributed the recent subdomain activity primarily to ShinyHunters based on victim targeting patterns and operational behavior. The company stated it has no independently verifiable evidence confirming that the broader SLH collective is responsible for the subdomain campaign, though partial collaboration among groups remains possible. It also observed Telegram discussions indicating that the actors sometimes “unite” for specific social engineering operations, though the structure and scope of such collaboration remain unclear. Security experts increasingly warn that help desks represent a critical weak point in modern enterprise defense. As organizations strengthen technical controls such as MFA and endpoint detection, attackers are redirecting efforts toward human intermediaries capable of overriding safeguards. Industry reporting throughout 2024 and 2025 has shown a consistent rise in vishing-led intrusions tied to cloud identity compromise. Defensive recommendations include implementing stricter identity verification workflows, eliminating SMS-based authentication where possible, enforcing conditional access policies, and conducting post-call audits for new administrative accounts or privilege changes. Continuous monitoring of cloud logs and abnormal single sign-on activity is also considered essential. The recruitment-driven expansion of scripted vishing operations signals an ongoing professionalization of social engineering. Rather than relying solely on technical exploits, threat actors are scaling psychologically informed tactics to accelerate high-volume, low-cost account compromise across enterprise environments.

 Ransomware payouts surged to unprecedented levels in the second quarter of 2025, driven largely by the rise of highly targeted social engineering schemes. According to new data from Coveware by Veeam, the average ransom payment skyrocketed to $1.13 million, representing a 104% jump compared to the previous quarter. The median ransom also doubled to $400,000, highlighting how even mid-tier victims are now facing significantly higher costs. Analysts attribute this spike to larger organizations paying ransoms in incidents where data was stolen rather than encrypted, marking a significant shift in extortion tactics.   The study found that data exfiltration has now overtaken file encryption as the primary method of extortion, with 74% of attacks involving theft of sensitive information. Multi-extortion techniques, including delayed release threats, are also on the rise. Bill Siegel, CEO of Coveware by Veeam, described the findings as a pivotal moment for ransomware, explaining that threat actors are no longer focused solely on disrupting backups or locking systems. Instead, they increasingly exploit people, organizational processes, and the reputational value of stolen data.  The report identified the leading ransomware variants for the quarter as Akira, responsible for 19% of incidents, followed by Qilin at 13% and Lone Wolf at 9%. Notably, Silent Ransom and Shiny Hunters entered the top five variants for the first time, reflecting the growing influence of newer threat groups. Among the most concerning trends was the heavy reliance on social engineering by groups such as Scattered Spider, Silent Ransom, and Shiny Hunters, who have shifted from broad, opportunistic attacks to precise impersonation schemes. By targeting help desks, employees, and third-party service providers, these actors have refined their ability to gain initial access and execute more lucrative attacks.   Exploitation of known vulnerabilities in widely used platforms including Ivanti, Fortinet, VMware, and Microsoft services remains a common entry point, often taking place immediately after public disclosure of security flaws. At the same time, “lone wolf” cybercriminals armed with generic, unbranded ransomware toolkits are increasing in number, allowing less sophisticated actors to successfully infiltrate enterprise systems. Insider risks and third-party vulnerabilities also rose during the quarter, particularly through business process outsourcing firms, contractors, and IT service providers. Researchers warned that these external partners often hold privileged credentials but lack direct oversight, making them an attractive avenue for attackers.  The professional services sector was hit hardest, accounting for 20% of all incidents, followed closely by healthcare and consumer services at 14% each. Mid-sized companies with between 11 and 1,000 employees represented 64% of victims, a range that attackers consider optimal for balancing ransom potential against weaker defenses. Before executing data theft or encryption, many attackers are spending additional time mapping networks, identifying high-value assets, and cataloging sensitive systems. This reconnaissance phase often blends in with normal administrative activity, using built-in system commands that are difficult to detect without contextual monitoring. Experts note, however, that detection can be improved by monitoring unusual enumeration activity or deploying deception techniques such as honeyfiles, decoy credentials, or fake infrastructure to trigger early alerts.  Siegel emphasized that organizations must now treat data exfiltration as an immediate and critical risk rather than a secondary concern. Strengthening identity controls, monitoring privileged accounts, and improving employee awareness against social engineering were highlighted as essential steps to counter evolving ransomware tactics. With attackers increasingly blending technical exploits and psychological manipulation, businesses face mounting pressure to adapt their defenses or risk becoming the next high-value target.

 Allianz Life Insurance has disclosed a major cybersecurity breach that exposed the personal details of approximately 1.4 million individuals. The breach was detected on July 16, 2025, and the company reported the incident to the Maine Attorney General’s office the following day. Initial findings suggest that the majority of Allianz Life’s customer base may have been impacted by the incident.  According to Allianz Life, the attackers did not rely on exploiting technical weaknesses but instead used advanced social engineering strategies to deceive company employees. This approach bypasses system-level defenses by manipulating human behavior and trust. The cybercriminal group believed to be responsible is Scattered Spider, a collective that recently orchestrated a damaging attack on UK retailer Marks & Spencer, leading to substantial financial disruption.  In this case, the attackers allegedly gained access to a third-party customer relationship management (CRM) platform used by Allianz Life. The company noted that there is no indication that its core systems were affected. However, the stolen data reportedly includes personally identifiable information (PII) of customers, financial advisors, and certain employees. Allianz SE, the parent company, confirmed that the information was exfiltrated using social engineering techniques that exploited human error rather than digital vulnerabilities.  Social engineering attacks often involve tactics such as impersonating internal staff or calling IT help desks to request password resets. Scattered Spider has been known to use these methods in past campaigns, including those that targeted MGM Resorts and Caesar’s Palace. Their operations typically focus on high-profile organizations and are designed to extract valuable data with minimal use of traditional hacking methods.  The breach at Allianz is part of a larger trend of rising cyberattacks on the insurance industry. Other firms like Aflac, Erie Insurance, and Philadelphia Insurance have also suffered similar incidents in recent months, raising alarms about the sector’s cybersecurity readiness.   Industry experts emphasize the growing need for businesses to bolster their cybersecurity defenses—not just by investing in better tools but also by educating their workforce. A recent Experis report identified cybersecurity as the top concern for technology firms in 2025. Alarmingly, Tech.co research shows that nearly 98% of senior leaders still struggle to recognize phishing attempts, which are a common entry point for such breaches.  The Allianz Life breach highlights the urgent need for organizations to treat cybersecurity as a shared responsibility, ensuring that every employee is trained to identify and respond to suspicious activities. Without such collective vigilance, the threat landscape will continue to grow more dangerous.

 A recently enhanced version of the Interlock remote access Trojan (RAT) is being deployed in an ongoing web-inject campaign linked to the ransomware group behind it. Known for its double-extortion tactics, Interlock has now shifted its technical approach with a more covert RAT variant written in PHP. According to a new report by The DFIR Report, this marks a significant advancement in the group’s capabilities and strategy.   Interlock first emerged in late 2024, attacking high-profile targets such as Texas Tech University’s Health Sciences Centers. Earlier this year, cybersecurity firm Quorum Cyber detailed two versions of the group’s malware, named NodeSnake, focused on maintaining persistence and exfiltrating data. The newest version introduces additional stealth features, most notably a transition from JavaScript to PHP, allowing the malware to blend more easily with normal web traffic and avoid detection.  This enhanced RAT is tied to a broader web-inject threat campaign dubbed “KongTuke,” where victims are tricked into running malicious scripts after visiting compromised websites. Visitors encounter what appears to be a legitimate CAPTCHA but are actually prompted to paste dangerous PowerShell commands into their systems. This action initiates the Interlock RAT, giving attackers access to the machine.  Once activated, the malware gathers extensive data on the infected system. Using PowerShell, it collects system information, running processes, mounted drives, network connections, and checks its own privilege level. This enables attackers to evaluate the environment quickly and plan further intrusion tactics. It then connects back to command-and-control infrastructure, leveraging services like Cloudflare Tunneling for stealthy communication. Remote desktop protocol (RDP) is used for lateral movement and persistent access.  Researchers say the targeting in this campaign appears opportunistic, not industry-specific. Victims across various sectors in the U.S. have been identified, with the attackers casting a wide net and focusing efforts where systems and data seem valuable or more vulnerable.   Defensive recommendations from experts include improving phishing awareness, restricting the use of the Windows Run dialog box, enforcing least privilege access, and requiring multifactor authentication. Blocking unnecessary use of RDP is also essential.  The growing sophistication of the Interlock RAT and its integration into mass web-inject campaigns reflects an evolving cyber threat landscape where stealth, automation, and social engineering play a central role.

 The FBI has issued a warning about a sophisticated cybercriminal group known as the Silent Ransom Group (SRG), also referred to by aliases like Luna Moth, Chatty Spider, and UNC3753. This group has been actively targeting U.S.-based law firms and related organizations through advanced phishing techniques and social engineering scams. The group, which has been operational since 2022, is known for using deceptive communication methods to gain unauthorized access to corporate systems and extract sensitive legal data for ransom demands. In the past, SRG’s activities spanned across industries such as healthcare and insurance.  However, since the spring of 2023, its focus has shifted to legal entities, likely because of the highly confidential nature of the data managed by law firms. The group commonly uses a method called callback phishing, also known as reverse vishing. In this approach, victims receive emails that appear to originate from reputable companies and warn them of small charges for fake subscriptions. The emails prompt users to call a phone number to cancel the subscription. During these calls, victims are instructed to download remote access software under the guise of resolving the issue. Once the software is installed, SRG gains control of the victim’s device, searches for valuable data, and uses it to demand ransom.   In March 2025, SRG has adapted their strategy to include voice phishing or vishing. In this new approach, the attackers call employees directly, posing as internal IT staff. These fraudulent callers attempt to convince their targets to join remote access sessions, often under the pretext of performing necessary overnight maintenance. Once inside the system, the attackers move swiftly to locate and exfiltrate data using tools like WinSCP or a disguised version of Rclone. Notably, SRG does not prioritize escalating privileges, instead focusing on immediate data theft. The FBI noted that these voice phishing methods have already resulted in multiple successful breaches.  SRG reportedly continues to apply pressure during ransom negotiations by making follow-up calls to victim organizations. While the group does maintain a public site for releasing stolen data, its use of this platform is inconsistent, and it does not always follow through on threats to leak information. A significant concern surrounding these attacks is the difficulty in detection. SRG uses legitimate system management and remote access tools, which are often overlooked by traditional antivirus software. The FBI advises organizations to remain vigilant, particularly if there are unexplained downloads of programs such as AnyDesk, Zoho Assist, or Splashtop, or if staff receive unexpected calls from alleged IT personnel.  In response, the FBI urges companies to bolster cybersecurity training, establish clear protocols for authenticating internal IT requests, and enforce two-factor authentication across all employee accounts. Victims of SRG attacks are encouraged to share any information that might assist in ongoing investigations, including ransom communications, caller details, and cryptocurrency wallet data.

ClickFix attacks are rapidly becoming a favored tactic among advanced persistent threat (APT) groups from North Korea, Iran, and Russia, particularly in recent cyber-espionage operations. This technique involves malicious websites posing as legitimate software or document-sharing platforms. Targets are enticed through phishing emails or malicious advertising and then confronted with fake error messages claiming a failed document download or access issue.  To resolve the supposed problem, users are instructed to click a “Fix” button that directs them to run a PowerShell or command-line script. Executing this script allows malware to infiltrate their systems. Microsoft’s Threat Intelligence division highlighted earlier this year that the North Korean group ‘Kimsuky’ utilized a similar approach through a fake “device registration” page.  A new report from Proofpoint now confirms that Kimsuky, along with Iran’s MuddyWater, Russia’s APT28, and the UNK_RemoteRogue group, deployed ClickFix techniques between late 2024 and early 2025. Kimsuky’s campaign, conducted between January and February 2025, specifically targeted think tanks involved in North Korean policy research. The attackers initially contacted victims using spoofed emails designed to appear as if they were sent by Japanese diplomats. After gaining trust, they provided malicious PDF attachments leading to a counterfeit secure drive. Victims were then asked to manually run a PowerShell command, which triggered the download of a second script that established persistence with scheduled tasks and installed QuasarRAT, all while distracting the victim with a harmless-looking PDF.  In mid-November 2024, Iran’s MuddyWater launched its campaign, targeting 39 organizations across the Middle East. Victims received phishing emails disguised as urgent Microsoft security alerts, prompting them to run PowerShell scripts with administrative rights. This led to the deployment of ‘Level,’ a remote monitoring and management (RMM) tool used to conduct espionage activities. Meanwhile, Russian group UNK_RemoteRogue focused on two organizations tied to a leading arms manufacturer in December 2024. Attackers used compromised Zimbra servers to send fake Microsoft Office messages. Clicking the embedded links directed victims to fraudulent Microsoft Word pages featuring Russian-language instructions and a video tutorial.  Victims executing the provided script unknowingly triggered JavaScript that ran PowerShell commands, connecting their systems to a server managed through the Empire C2 framework. Proofpoint also found that APT28, an infamous Russian cyber-espionage unit, used ClickFix tactics as early as October 2024. In that instance, phishing emails mimicked Google Spreadsheet notifications, including a fake reCAPTCHA and a prompt to execute PowerShell commands. Running these commands enabled attackers to create an SSH tunnel and activate Metasploit, providing them with covert access to compromised machines.  The growing use of ClickFix attacks by multiple state-sponsored groups underscores the method’s effectiveness, primarily due to the widespread lack of caution when executing unfamiliar commands. To avoid falling victim, users should be extremely wary of running scripts or commands they do not recognize, particularly when asked to use elevated privileges.
