A new macOS malware called notnullOSX has surfaced in early 2026, specifically built to steal cryptocurrency from Mac users who hold digital assets worth more than $10,000. The threat is real, active, and carefully constructed to look completely legitimate at every step of its infection process. The story behind this malware goes back to 2023, when a developer known online as 0xFFF abruptly left a well-known underground hacking forum after being tricked into believing Russian and Ukrainian security services were investigating him. In August 2024, he returned under a new alias, alh1mik, with an apology and a concrete offer: reinstatement in exchange for a brand-new macOS stealer. By early 2026, that promise became notnullOSX, a sophisticated Go-written stealer delivered through social engineering, a fake wallpaper application, and a hijacked YouTube channel. The malware was built with one goal in mind: draining cryptocurrency holdings above the $10,000 mark from macOS users. Moonlock Lab researchers identified and recorded the first detections of notnullOSX on March 30, 2026, across three regions: Vietnam, Taiwan, and Spain. Their telemetry analysis revealed a multi-layered distribution operation that combined fake Google documents, a polished fake wallpaper website, and a stolen YouTube account to reach unsuspecting Mac users. The targeting is not random. Before a victim is approached, operators manually fill out a submission form identifying the target’s wallet address, social media profiles, and wallet balance. The panel documentation explicitly states the minimum threshold is $10,000, and submissions below that amount are simply not processed. The attack starts when a victim receives a fake “protected” Google document. Opening it shows a convincing but fraudulent interface with an encryption error, falsely attributed to an outdated “Google API Connector.” Two options appear to fix the problem. Both deliver the same malware. One path, called ClickFix, presents a Terminal command that, when pasted and run, silently downloads and installs the malware. The second path uses a fake disk image file called WallSpace.app, disguised as a legitimate macOS live wallpaper application. Traffic to the malicious site was driven by a hijacked YouTube channel registered back in 2015 that had accumulated 50,000 views within two weeks of posting a single video. A decade-old account with minimal subscribers suddenly racking up tens of thousands of views on a single video is a strong signal that the account was compromised and used to push the malware to unsuspecting viewers. Once installed, notnullOSX operates silently and persistently, extracting data from iMessages, Apple Notes, Safari cookies, browser passwords, Telegram sessions, and a wide range of cryptocurrency wallets including Bitcoin Core, Exodus, and Electrum. Perhaps most concerning is a module called ReplaceApp, which silently swaps legitimate hardware wallet applications like Ledger Live with malicious clones designed to intercept seed phrases during wallet setup, something many users would never detect. The implant also maintains a live connection back to the attacker’s server, meaning operators can send fresh instructions to infected machines long after the initial compromise. How the Infection Chain Works The ClickFix infection path relies heavily on the trust that developers and crypto users place in their own Terminal application. The base64-encoded command shown to the victim decodes into a curl command that fetches a bash installer script from a remote server. That script downloads a Mach-O binary , makes it executable, removes Apple’s Gatekeeper quarantine flag, and sets up a LaunchAgent to run automatically on startup. The victim is then guided through enabling Full Disk Access in System Settings, which is the most critical step in the whole chain. ClickFix terminal command as seen in the notnullOSX lure (Source – Moonlock) Granting Full Disk Access bypasses macOS’s TCC (Transparency, Consent, and Control) framework entirely. This framework normally requires individual permission prompts before any app can read sensitive data such as Messages, Notes, Safari cookies, and Contacts. Once the victim grants Full Disk Access, the malware quietly sidesteps every one of those individual prompts simultaneously, reading every protected folder without triggering a single pop-up. The victim willingly hands over the keys because they believe it is a normal installation requirement. WallSpace fake product page used as a distribution lure (Source – Moonlock) The DMG path through the fake WallSpace app is equally deceptive but slightly simpler from the victim’s perspective. Mounting the disk image reveals three files: an installer script, a README file, and a Terminal shortcut. The README walks the victim through the steps while the shortcut opens Terminal automatically from the mounted volume. The installer script, despite being nearly 299 KB, presents itself as a block of plain text. When decoded, the same malware implant used in the ClickFix chain emerges. Hijacked YouTube channel hosting the fake WallSpace video (Source – Moonlock) Moonlock Lab’s analysis confirmed that the malware binary is a 27.74 MB multi-architecture Mach-O file built for both Apple Silicon and Intel Macs. At the time of discovery, only 10 out of 64 vendors on VirusTotal flagged it, meaning the vast majority of standard detection tools would have missed it entirely. Users and security teams should take the following steps to protect against notnullOSX and similar threats: Never paste Terminal commands sourced from a browser, a document, or a YouTube video description. Treat any application that requests Full Disk Access during installation as suspicious and verify the developer before granting it. Regularly audit the folder ~/Library/LaunchAgents/ for unfamiliar or unexpected files. Security teams should block and monitor outbound connections to mactest-6b2ab-default-rtdb[.]firebaseio.com and flag Mach-O binaries downloaded from cdn.filestackcontent[.]com. Alert on any process calling xattr -rd com.apple.quarantine from a browser or document context. Check the /tmp directory regularly for short-lived Mach-O files, especially those with names matching patterns like SystemInfoGrab, CryptoWalletsGrab, or ReplaceApp. Follow us on  Google News ,  LinkedIn , and  X  to Get More Instant Updates ,  Set CSN as a Preferred Source in  Google .

A new macOS info-stealer named notnullOSX has surfaced, targeting crypto holders with wallets above $10,000. Written in Go, it uses two parallel attack paths — ClickFix social engineering and malicious DMG disk image files — to silently compromise Apple Mac systems. The malware is highly targeted, with operators hand-picking each victim through an affiliate panel before launching an attack. The story behind notnullOSX stretches back to 2022 and a developer known as 0xFFF, who first posted about a rough macOS stealer on underground forums. After a dramatic exit in 2023 — triggered by a fabricated law enforcement tip reportedly set up by a rival — 0xFFF disappeared, leaving paying subscribers without refunds. In August 2024, the same actor returned under a new alias, alh1mik, posted an apology, and began taking preorders for a new macOS stealer at $400 per month. By 2026, that offer had materialized. Moonlock Lab researchers identified and recorded the first detections of notnullOSX on March 30, 2026, across three regions — Vietnam, Taiwan, and Spain. Their telemetry confirmed how deliberately the malware had been constructed: before targeting anyone, operators must fill out a submission form that includes the victim’s social media profiles, wallet address, and correspondence history. The minimum wallet threshold is set at $10,000, and submissions below that figure are automatically rejected. The infection begins with a fake protected Google document, which shows an encryption error and urges the victim to take one of two actions — both leading to the same malware. The first path uses ClickFix: the victim is told to open Terminal and paste a base64-encoded command, which silently fetches and executes a remote bash installer script. The second delivers a malicious DMG disk image containing a README, an install script, and a Terminal shortcut, packaged to look entirely routine. In both cases, the victim unknowingly installs the malware without triggering a single security warning. The distribution network goes further. A fake product page for a wallpaper app called WallSpace was set up at wallpapermacos[.]com, with polished screenshots and a free download button.  Fake WallSpace product page and ClickFix terminal prompt (Source – Moonlock) A hijacked YouTube channel, dormant since 2015, promoted the fake app with a single video that accumulated 50,000 views in just two weeks — consistent with paid promotion or SEO manipulation. Inside the Attack: TCC Bypass and Modular Data Theft What makes notnullOSX particularly dangerous is how it turns macOS’s own permission system against its users. Normally, Apple’s Transparency, Consent, and Control (TCC) framework triggers a pop-up every time an app tries to access protected data — messages, notes, browser cookies, and more. notnullOSX sidesteps this by walking victims into manually granting Full Disk Access in System Settings. Full Disk Access grant in System Settings (Source – Moonlock) That single permission covers every protected data category at once, with no further dialogs appearing. The malware operates through a modular architecture, downloading separate binaries from its C2 server to handle each theft task. Confirmed modules include iMessageGrab, AppleNotesGrab, CryptoWalletsGrab, BrowserGrab, TelegramGrab, CredsGrab, and ReplaceApp. Staged module binaries in tmp during execution (Source – Moonlock) ReplaceApp is especially alarming: it silently swaps a legitimate hardware wallet app like Ledger Live with a trojanized clone designed to intercept seed phrases at setup. Even users relying on hardware wallets are at risk if the managing app on their Mac is replaced without any visible sign. Beyond theft, notnullOSX holds a persistent WebSocket connection to a Firebase-hosted C2 server, sending regular heartbeats and waiting for remote commands — behavior far closer to a remote access trojan than a one-time stealer. Moonlock Lab’s detection notes recommend that security teams block outbound connections to the known C2 domain, alert on Full Disk Access grants to unrecognized applications, and monitor /tmp for staged Mach-O binaries. For Mac users and crypto holders, the advice is direct: never paste Terminal commands from a browser or document, treat any app requesting Full Disk Access during installation as suspicious, and check ~/Library/LaunchAgents/ for unfamiliar entries.

## Proper Guide For Advertising App Elimination **notnullOSX** is a harmful program made to attack Apple computers that run macOS. Its main purpose is to secretly collect personal and valuable information from users. Cybercriminals spread it by hiding it inside fake or infected files, often pretending to be something useful or safe. When a person downloads and opens one of these files, the malware gets installed without them realizing what is happening. Once inside the computer, notnullOSX malware tries to get deep access to the system. This allows it to see and copy many types of data stored on the device. It can connect to a remote server controlled by attackers and download extra tools that help it perform different tasks. These tools work together to gather sensitive information from the infected system. One of its main targets is web browser data. It can collect saved passwords, browsing history, cookies, and bookmarks from browsers like Chrome, Firefox, and Safari. With this information, attackers can access accounts without needing to log in normally. It also focuses heavily on cryptocurrency wallets, trying to steal data that could let hackers take control of digital money stored by the user. The malware also goes beyond financial theft. It can access private messages and files from apps such as Telegram, including conversations and attachments. In addition, it searches for important technical data like SSH keys, cloud account details, and API tokens. This kind of information can be used to break into servers, online services, or work-related systems, making it dangerous for both personal and professional use. Another dangerous feature of notnullOSX is its ability to act like a remote control tool for hackers. It stays connected to their server, allowing them to send new instructions or update its behavior at any time. It can even replace real apps with fake ones that look normal but secretly steal data. Because it can keep changing and improving itself, it is difficult to detect, which is why removing it quickly is very important if it is found. ### Quick Glance --- **Name:** notnullOSX **Class:** Mac virus, Trojan **Features:** Alters the user’s browsing experience by changing the default search engine and homepage, displays unwanted ads, and redirects the user to malicious websites. **Danger level:** Medium **Symptoms:** The unwanted application can cause several adverse effects, such as displaying intrusive pop-up ads and slowing down internet browsing.

Below, we will discuss some of the harms that notnullOSX can cause. 1. **Modify Your Browser Settings:** It can modify your browser settings, such as your homepage, default search engine, and new tab page. This can be very frustrating, as it can take a long time to reset these settings back to their original state. 2. **Display Annoying Ads:** This hijacking app often displays unwanted ads, pop-ups, and banners on your screen. These ads can be very annoying, and can even lead to more harmful content if you click on them. In some cases, the ads may even be used to trick you into downloading more malware. 3. **Redirect Your Web Traffic:** It can redirect your web traffic to other sites, even if you didn’t intend to visit those sites. This can be very dangerous, as the sites you are redirected to may contain harmful content, such as malware, phishing scams, or other types of scams. 4. **Slow Down Your Computer:** One of the most obvious harms of hijackers or adware like notnullOSX is that they can slow down your computer. This is because they are constantly running in the background, using up valuable system resources. This can cause your device to become sluggish, unresponsive, and even crash. 5. **Cause Browser Crashes:** notnullOSX can also cause your browser to crash or freeze. This can be very frustrating, as it can cause you to lose any work you were doing, or even cause you to lose important data if you haven’t saved your work. 6. **Decrease Your Online Privacy:** This undesired software piece can decrease your online privacy by tracking your browsing habits, collecting your personal information, and displaying unwanted ads. This can be very harmful, as it can expose you to identity theft, fraud, and other types of cybercrime. In short, notnullOSX can cause a wide range of harms to your device and your privacy. Therefore, it is important to take steps to protect your computer from this hijacking application, such as using antivirus software, keeping your browser and operating system up to date. ### Is notnullOSX a dangerous virus? notnullOSX is a type of malware that can cause a lot of unkind issues inside the compromised systems. While many don’t consider it as a destructive virus in the sense that it is not intended to damage the device, it can be a nuisance and potentially compromise the user’s online security. Additionally, it may indirectly expose their system to more dangerous form of viruses and malware. Browser hijackers or adware can make your computer more vulnerable to other types of attacks. This is because they often disable your antivirus software, firewall, and other security measures that are designed to protect your system from malware and other types of attacks. notnullOSX can also be used to install other types of malware on your computer, such as adware, spyware, and even ransomware. These types of malware can cause even more harm, such as stealing your files, encrypting them, and demanding a ransom to unlock them. In addition to that, such browser-based infections are often designed to collect users’ personal data, such as their browsing history, search queries, and even their login credentials. This information can be used for identity theft, fraud, and other malicious activities. For these reasons, notnullOSX can still be considered a dangerous computer virus, and must be eliminated from the system as early as possible. ### notnullOSX Redirection Leads to Unsafe Sites The redirection chain triggered by notnullOSX may force the browser to send the user to a variety of different webpages. Nonetheless, it’s pertinent to note that most of the websites it sends people to are malicious and even dangerous and may pose a serious threat to the device and the browser. This undesired software piece may take users to following sites: **Tech Support Scam Sites** Many people are falling victim to tech support scam websites that have become increasingly widespread. These sites often imitate the appearance of legitimate operating system error messages, making it difficult for individuals to discern whether the message is genuine or a scam. As a result, users are easily fooled into giving scammers access to their personal information or paying for unnecessary and expensive services. **Unsafe Dating Website** notnullOSX pop-ups may lead you to dubious dating sites that are entirely controlled by robots. Such websites often display deceptive notifications and pop-ups that mislead users into believing that they have multiple chat requests or messages waiting for them. These false alerts may be designed to look convincing and may even use persuasive language to create a sense of urgency, tricking users into clicking on them. In reality, these notifications are usually a tactic employed by scammers to lure individuals into interacting with their fraudulent websites or downloading malicious software. **Websites Showing Fake Virus Alert:** These sites tend to display fake security alerts claiming that users’ PCs are infected with several viruses. They are designed to trick visitors into believing that they are in trouble of having their computers infected and to compel them into taking immediate actions. Scammers behind these deceptions aim to mislead users into downloading and installing malicious software or extracting money from them for useless services. **Drive-by Download Malware Sites** Users may also be taken to drive-by download websites, which is a type of cyberattack in which malware is automatically downloaded to a computer without the user’s knowledge or consent. Drive-by downloads are a serious security threat, as they can result in the installation of viruses, spyware, or other types of malicious software, which can compromise the security and privacy of your computer and personal data. **Fake Giveaway Survey Websites** These dubious sites tend to promote bogus surveys aiming to trick users into stealing their personal information such as their credit card details, banking credentials, etc. This sort of information could later be used for various malicious purposes and may lead to a number of unpleasant issues. **Unsafe Pop-Ups Causes Online Scam** Unsafe pop-ups are a common method used by online scammers to deceive unsuspecting internet users. These pop-ups can appear on users’ browser when their system is contaminated with an unwanted application; they visit a website or click on a link, and often try to convince them to take some action, such as downloading a program or providing personal information. Once users interact with the pop-up, they can be redirected to a fraudulent website that looks legitimate, but is actually designed to steal their sensitive data or money. For example, a notnullOSX pop-up might claim that users’ device is infected with a virus and prompt them to download software that is actually malware. Other pop-ups might offer a prize or gift in exchange for the user’s personal information, such as their name, address, and credit card number. Once the scammers have this information, they can employ it to make unauthorized purchases or commit identity theft. This can lead to serious privacy issues, identity fraud, high-risk system infections, and even significant monetary losses. ### How did notnullOSX Attack my device? Browser-based parasites like notnullOSX can infect PC systems through a number of deceptive ways. Below are some key points on how these types of malware can sneak into the targeted devices: 1. 1. **Bundled Software:** Adware and browser hijackers are often bundled with legitimate software that users download from the internet. This could be a free utility or game that is made available for download from a website. The site may offer the program for free, but it will be bundled with additional software that the user may not be aware of. When the user download and installs the program, the bundled software will also be installed on their system without their knowledge or consent. This bundled software may include a browser hijacker or adware that will modify the user’s web browser settings. 2. **Malicious Websites:** notnullOSX can also spread through malicious websites. These sites are designed to trick users into downloading and installing software or visiting other harmful web places. People visit a malicious website often by clicking on a link in a spam email, a social post, or a search engine result. The site contains code that automatically downloads and installs the undesired software piece onto the users’ computer without their knowledge or approval. 3. **Exploits:** Other way through which PUPs like notnullOSX can enter the computer systems is exploits. Exploits are vulnerabilities in software that can be exploited by attackers to gain unauthorized access to a computer system or to install malware or adware. Threat actors find a vulnerability in the user’s web browser, operating system, or a plugin, such as Java or Flash. After that, they create a website that contains code that exploits the vulnerability when the user visits the site. The exploit downloads and installs the parasite onto the PC without users’ awareness or consent. 4. **Social Engineering:** notnullOSX can make its way into the device through social engineering as well, which is a technique used by hackers to trick users into downloading and installing malware. These internet criminals create a fake advertisement or pop-up message that claims the user needs to update their software or install a new plugin to view content on a website. The pop-up message may contain a convincing message, such as “Your Flash Player is out of date, please click here to update it” or “Your computer is infected, click here to remove the virus.” When users click on the pop-up message, they end up downloading and installing the unwanted program without realizing it. **Special Offer (For Macintosh)** **notnullOSX** can be creepy computer infection that may regain its presence again and again as it keeps its files hidden on computers. To accomplish a hassle free removal of this malware, we suggest you take a try with a powerful antimalware scanner to help you getting rid of this virus **Download Free Scanner For Mac** **“Combo Cleaner” free scanner downloaded just scans and detects threats present in the computers.

As soon as notnullOSX infiltrates the PC system, it starts carrying out malicious activities in the background and may lead to a number of unpleasant issues. To avoid getting infected with such browser-based pests, below are some steps you can take: * **Download software from reputable sources:** Only download software from reputable websites, such as the official page of the software vendor or well-known download portals. Avoid downloading software from third-party websites or peer-to-peer networks, as these are often sources of bundled adware. * **Pay attention during the installation process:** When installing software, pay attention to each step of the installation process. Look for the checkboxes that may indicate the installation of additional software, such as adware or browser extensions. Uncheck these boxes if you don’t want to install the additional software. * **Choose custom installation:** During the installation process, choose the custom installation option instead of the default or express installation. This will allow you to select which components to install and to opt-out of installing any bundled adware or other unwanted software. * **Read the End User License Agreement (EULA):** Read the EULA carefully before installing any software. Look for clauses that may allow the installation of additional software or adware like notnullOSX. If EULA contains such clauses, reconsider installing the software. * **Use a reputable web browser:** Choose a reputable web browser, such as Google Chrome or Mozilla Firefox, and keep it up-to-date with the latest security patches. * **Install ad-blockers and pop-up blockers:** You should use ad-blockers and pop-up blockers to prevent unwanted ads and pop-ups from appearing on your computer screen. Some web browsers have built-in ad-blocker and pop-up blockers, or you can install browser extensions that provide this functionality. * **Be careful when clicking on links:** Don’t click on links in emails or on websites unless you are sure they are legitimate.
