Singapore is changing its cybersecurity strategy after a state-sponsored cyber espionage group targeted the country’s four major telecommunications companies. The attack by UNC3886, disclosed in July 2025, could have disrupted telecommunications and internet services had the attackers penetrated further and raised concerns about national security.  The incident has pushed Singapore toward a more proactive approach that assumes sophisticated attackers may eventually enter protected networks. Instead of focusing only on preventing intrusions, authorities are emphasizing threat hunting and the detection of suspicious activity after attackers gain access. In an interview, Cyber Security Agency of Singapore (CSA) chief executive and Commissioner of Cybersecurity Gwenda Fong said advanced persistent threat actors such as UNC3886 pursue specific targets, meaning perimeter protection alone is not enough.  Once inside a network, attackers still need to move toward sensitive systems and data, giving defenders opportunities to identify unusual internal activity. Singapore is using artificial intelligence to strengthen this detection and prevention work. The Government Technology Agency of Singapore (GovTech) has developed two AI-powered tools for government systems. One performs automated penetration testing across about 2,000 government systems, including systems containing citizen data and transactions.  The second scans the source code of government applications and systems for security weaknesses so agencies can address vulnerabilities before attackers exploit them. The authorities have not disclosed which agencies are using the tools, but their use is being evaluated for expansion across Singapore’s 11 critical information infrastructure sectors, which include healthcare, aviation, banking and finance, energy, government and information and communications.  CSA has also started regularly scanning internet-facing systems operated by critical infrastructure organizations to identify potential entry points such as unpatched software and weak configurations. The agency said these scans are external and do not involve active probing. Other measures include proprietary threat-detection tools developed by a technical agency under Singapore’s Ministry of Defence and the sharing of classified threat intelligence with critical infrastructure operators. CSA is also examining supply-chain security because compromised vendors could potentially expose data or disrupt services.  The agency is considering requiring some vendors and suppliers working with critical infrastructure operators to obtain Cyber Essentials or Cyber Trust mark certifications, potentially as early as 2027. As of August, 874 Cyber Essentials and 346 Cyber Trust mark certifications had been issued.  The shift reflects the growing importance of cybersecurity to national security, the digital economy and public trust. CSA reported that suspected advanced persistent threat activity in Singapore quadrupled between 2021 and 2024, while authorities expect threats to increase as attackers gain access to AI tools.  For organizations connected to critical digital infrastructure, the message is clear: security cannot end at the network perimeter. Identifying weaknesses, monitoring internal activity and detecting attackers before they can reach sensitive systems are becoming essential parts of defending increasingly connected services.

Microsoft’s New AI Cybersecurity Model Crushes the Competition Microsoft has revealed a potentially revolutionary AI cybersecurity model, MAI-Cyber-1-Flash, that it claims can outperform industry leaders…

OpenAI has announced the release of its Astra AI model, which is the first to meet the company's threshold for 'critical' cyber capabilities. The model can independently identify and exploit previously unknown software vulnerabilities, prompting OpenAI to implement safety measures and pause training workloads temporarily. Astra's advanced capabilities include chaining multiple exploits to penetrate systems, outperforming industry leaders like GPT-5.6 Sol and Anthropic's Mythos on cybersecurity benchmarks. While OpenAI emphasizes safeguards such as a 'misalignment monitor' to prevent misuse, cybersecurity experts caution that AI's growing hacking abilities pose significant risks to unprepared systems. The company is offering early access to select partners through its Daybreak Blue program to strengthen defenses before broader release. This development highlights ongoing industry challenges in balancing AI innovation with security protocols, as similar incidents have been reported by competitors like Anthropic and Meta.

  Security researchers are increasingly examining whether artificial intelligence can do more than accelerate existing cyberattacks and potentially develop entirely new methods of exploitation. A recently uncovered AI sandbox escape in Microsoft Copilot offers one of the clearest indications that AI environments could be exploited to reach systems and data beyond their intended boundaries. Joe Hladik, head of Zero Labs, the threat research division of Rubrik Inc., has spent years studying backup data, an area he believes remains relatively overlooked by the cybersecurity industry. This year, his team expanded its research to examine how organizations and employees are using AI assistants, beginning with Microsoft Copilot, which is used by around 20 million people and approximately 90% of Fortune 500 companies. “No one’s looking at backup data,” Hladik said. “We found it to be a viable place to find actual intelligence to act upon.” Hladik discussed the research with Krista Case during Black Hat USA in an interview broadcast by theCUBE, SiliconANGLE Media’s livestreaming studio. The conversation focused on Rubrik Zero Labs’ discovery involving Microsoft Copilot and the broader security implications for AI-powered agents. How the Microsoft Copilot sandbox escape worked Rubrik Zero Labs discovered the vulnerability in February and subsequently followed responsible disclosure procedures by notifying Microsoft. According to Hladik, Microsoft addressed the specific vulnerability by the middle of March. Although the particular flaw has been patched, Hladik said the research demonstrated a broader technique that could potentially be relevant to other AI copilots. The method involved escaping Copilot’s isolated environment and reaching Azure’s backend infrastructure. Researcher Ori Lahav is presenting the detailed findings at Black Hat USA. “[That] would allow you to get command and control of probably hundreds, thousands, or much more, depending on the volume of what exists within that tenant of users’ files, SharePoint files, OneDrive, whatever,” Hladik said. “It’s a major, major find.” The discovery also highlights the potential scale of an AI-related security incident. If an attacker were able to move beyond an AI assistant’s sandbox, access to organizational resources could potentially extend across files and other information stored within an enterprise environment. Organizations still lack visibility into AI agents The Copilot discovery comes as businesses rapidly deploy AI agents without necessarily having complete visibility into where those systems operate or what they can access. Research from Rubrik Zero Labs found that only 23% of security leaders have complete visibility into the AI agents operating within their organizations. Rubrik is attempting to address this challenge through new AI agent governance capabilities introduced this week. Hladik compared AI agents with technologies security teams have encountered before, arguing that their underlying architecture is not entirely unfamiliar. “Agents are just bots with models,” Hladik said. “They’re a bot that asks a model, and then the model will tell them what to do, and then they act. It’s new, it’s cool, but at the same time, I’ve seen this before.” The findings underscore a growing challenge for organizations deploying AI: securing not only the models themselves but also thwe environments, permissions, data and connected services that AI agents can interact with. As businesses increasingly integrate AI assistants into everyday workflows, vulnerabilities that allow these systems to escape their intended boundaries could create significant new attack surfaces.

The speed that AI can now discover and exploit vulnerabilities means that our defenses also need to adjust. For the devices that you manage where you can afford to tighten deployment timelines, we'll explain updated recommendations and show you how to speed up patching. It starts with assessing your risk exposure for unpatched devices using the new Autopatch report in Microsoft Intune, then tightening deferral policies on the devices where it makes sense, using Hotpatch to activate protection on install — without requiring reboots. Windows Autopatch automates your update deployments using rings to progressively apply updates to the device groups that you help define, including updates for Windows, Microsoft 365 Apps and the Edge browser. And to keep internal resources protected, you can enforce access controls using Conditional Access to block non-compliant devices. Jeremy Chapman, Microsoft 365 Director, shares what's changed along with the approaches you can take to help counter the growing number of AI-discovered vulnerabilities and stay protected. ► QUICK LINKS: 00:00 - AI and Windows patch management 01:13 - Updated patching deferral thresholds 01:46 - Hotpatch on by default 02:05 - Windows Autopatch report 02:30 - Ring-based deployment + M365 Apps servicing profile 02:50 - Conditional Access for non-compliant devices 03:16 - Wrap up ► Link References For what you can do beyond patching, go to https://aka.ms/securenow ► Unfamiliar with Microsoft Mechanics?
