The modern cybercriminal isn't just writing malware anymore. They're building brands. In a campaign recently highlighted by cybersecurity researchers, scammers have been caught creating an entire ecosystem of fake credibility around malicious software. By abusing platforms such as GitHub, manipulating reputation signals on VirusTotal, and flooding the internet with AI-generated promotional content, attackers are convincing users to willingly install malware designed to steal cryptocurrency. It's a shift that reflects a broader trend in cybercrime: instead of breaking through security barriers, criminals are increasingly focused on persuading victims to open the door themselves. Building a Reputation That Doesn't Exist The operation begins where many developers and technology enthusiasts search for software: GitHub. Researchers found that threat actors were creating repositories that appeared legitimate at first glance. Some projects were presented as useful develop...

Suspected API Misconfiguration While ServiceNow has not released detailed technical information about the vulnerability, discussions among administrators and security researchers point to a potentially exposed API endpoint associa...

An anonymous security researcher known as Chaotic Eclipse (also tracked as Nightmare-Eclipse and MSNightmare) has publicly released a proof-of-concept exploit for yet another unpatched Microsoft Defender zero-day, this one dubbed RoguePlanet. The exploit works on fully updated Windows 10 and Windows 11 systems with the June 2026 Patch Tuesday updates installed, and when successful, delivers a shell with SYSTEM-level privileges the highest level of access on a Windows machine. How the Exploit Works RoguePlanet is a race condition vulnerability, meaning it exploits a timing gap between two operations in Microsoft Defender's code. The researcher acknowledged the exploit is not perfectly consistent across all machines success rates varied significantly depending on the target system, but noted that independent security researcher Will Dormann confirmed it worked on the first attempt on his machine. The exploit does not currently function against Windows Server installations in its p...

Security researchers disclosed a new software supply chain campaign attributed to the North Korean threat actor Lazarus Group. The operation targets software developers through malicious packages uploaded to the npm registry, one of the world's largest repositories for JavaScript software components. Unlike traditional typosquatting attacks that rely on simple spelling mistakes, this campaign uses a more sophisticated technique known as brandjacking, where malicious packages are intentionally designed to appear related to legitimate and widely trusted open-source projects. According to research conducted by Sonatype, dozens of malicious packages were identified as part of the campaign, with some accumulating hundreds of downloads before detection and removal. The attackers created package names that appeared to be extensions, companion tools, utilities, or ecosystem components associated with popular projects such as React, Express, Webpack, Chai, JWT libraries, and Buffer. By usi...

Threat actors are actively exploiting a critical remote code execution vulnerability in Everest Forms Pro , a WordPress plugin used by approximately 4,000 websites. The flaw, tracked as CVE-2026-3300 with a near-maximum CVSS score of 9.8, allows completely unauthenticated attackers to execute arbitrary PHP code on affected servers and take full control of vulnerable sites. What the Vulnerability Does The root cause of the flaw lies in the Calculation Addon's process_filter() function, which takes user-submitted form field values and concatenates them directly into a PHP code string before passing it to PHP's eval() function without proper escaping. The sanitization function applied to user input does not strip single quotes or other PHP-specific characters, meaning an attacker can simply submit a crafted value through any standard string-type form field including text, email, URL, select, or radio fields on any form that uses the "Complex Calculation" feature. T...

Cybersecurity researchers at OX Security have uncovered a malicious package on the npm registry that specifically targets files stored in Anthropic's Claude AI tool directory. The campaign, dubbed Malware-Slop , centers around a package named mouse5212-super-formatter and represents a growing trend of AI-focused supply chain attacks carried out with low operational sophistication, but real consequences. What the Package Does On the surface, the package presents itself as an internal "archive deployment sync" utility, claiming to validate GitHub repositories and send network diagnostic information. In reality, it is a data theft tool with a very specific target: the /mnt/user-data directory, the dedicated folder that Claude AI uses to handle file uploads and outputs in the background. The malicious behavior is triggered during the postinstall stage, meaning it executes automatically the moment a developer installs the package. At that point, the malware authenticates...

  Cybersecurity researchers at Qualys have uncovered a critical privilege escalation vulnerability in the Linux kernel that went undetected for nine years. Tracked as CVE-2026-46333 and codenamed "ssh-keysign-pwn" , the flaw was quietly introduced into the kernel back in November 2016 and affects default installations of several of the most widely used Linux distributions, including Debian, Ubuntu, and Fedora. What the Flaw Does The vulnerability stems from improper privilege management in the kernel's __ ptrace_may_access() function a core component that governs how one process can inspect or control another. An unprivileged local user who exploits this flaw can access highly sensitive files and escalate their privileges all the way to root, without requiring any special system configuration. In practice, a successful attack can expose the contents of /etc/shadow  the file containing hashed user passwords as well as private SSH host keys stored under /etc/ssh/ . Bey...

Cybersecurity researchers identified a large-scale malware campaign targeting job seekers through fake online interview platforms. The operation distributes a credential-stealing trojan known as JobStealer, which is disguised as legitimate video conferencing software for remote interviews. The campaign specifically targets Windows and macOS systems and focuses heavily on stealing browser credentials, cryptocurrency wallet data, authentication tokens, and sensitive personal information. The attack demonstrates how threat actors are increasingly exploiting remote work culture and employment-related social engineering to compromise victims. The attack begins with threat actors contacting victims through fake recruitment offers and interview invitations. Victims are directed to professionally designed websites pretending to host online interview platforms. Researchers identified multiple fake platform names such as MeetLab, Meetix, Juseo, and Carolla, while some sites directly impersonate...

Cybersecurity researchers uncovered an active malware campaign targeting software developers through fake installation pages impersonating Anthropic’s Claude Code platform. The operation relies heavily on social engineering and malicious search advertisements to trick victims into downloading or executing malware disguised as legitimate AI development tooling. The campaign demonstrates a growing trend where attackers exploit the popularity and rapid adoption of AI-assisted coding tools to compromise developer environments and steal sensitive browser data. The attack typically begins when a developer searches online for terms such as “install Claude Code” or “Claude Code CLI.” Attackers purchase sponsored search advertisements that appear above legitimate results, redirecting victims to convincing lookalike websites that closely mimic official Claude documentation pages. These fake pages replicate branding, layouts, installation guides, and command-line instructions in order to appear ...

  Cybersecurity researchers disclosed a critical Linux kernel vulnerability chain known as “Dirty Frag,” a local privilege escalation exploit capable of granting root access across most major Linux distributions released since 2017. The vulnerability quickly gained attention due to its high reliability, the public release of proof-of-concept exploit code, and the absence of immediate patches at the time of disclosure. Security analysts have compared Dirty Frag to previous high-profile Linux vulnerabilities such as Dirty Pipe and Copy Fail because of its ability to manipulate kernel memory structures and achieve deterministic privilege escalation. Dirty Frag is not a single vulnerability but a chained exploitation technique involving weaknesses in Linux kernel networking components related to xfrm-ESP and RxRPC functionality. By abusing flaws in the page cache handling logic, attackers can modify protected memory-backed files without appropriate permissions. This enables unprivilege...

Cybersecurity researchers reported a serious abuse of the digital certificate issuance process involving DigiCert, one of the world’s largest certificate authorities. Threat actors successfully obtained legitimate code-signing certificates and used them to digitally sign malicious software, allowing malware samples to appear trusted by operating systems and security solutions. The incident highlights the growing misuse of trusted digital infrastructure in modern cyberattacks and demonstrates how attackers increasingly exploit weaknesses in verification and identity validation processes rather than relying solely on technical vulnerabilities. Digital certificates are designed to establish trust between software publishers, operating systems, and users. When software is signed using a valid certificate, security mechanisms such as Microsoft SmartScreen and antivirus products are more likely to treat the application as legitimate. By obtaining valid certificates, attackers can bypass secu...

Cybersecurity researchers have uncovered a critical vulnerability in Ollama, one of the most widely used platforms for running large language models locally, that could allow a remote, unauthenticated attacker to read and steal the server's entire process memory. Tracked as CVE-2026-7482 and dubbed "Bleeding Llama" by the researchers at Cyera who discovered it, the flaw carries a CVSS score of 9.1 and is estimated to affect more than 300,000 publicly exposed servers worldwide. What Is Ollama? Ollama is a popular open-source framework that enables developers and organizations to run AI language models locally rather than relying on cloud services. The project has over 171,000 stars on GitHub, making it one of the most widely adopted tools in the self-hosted AI space. How the Vulnerability Works The flaw is an out-of-bounds heap read located in Ollama's GGUF model loader specifically in a function called WriteTo() within the model creation pipeline. GGUF is the sta...

Security researchers have disclosed a total of twelve vulnerabilities in vm2 , a widely used open-source Node.js library, several of which carry the maximum possible CVSS score of 10.0. All affected versions up to and including 3.11.1 are impacted, and users are strongly urged to upgrade to the newly released version 3.11.2 immediately. What Is vm2? vm2 is a Node.js sandbox library designed to safely execute untrusted JavaScript code in an isolated environment, preventing that code from accessing the underlying host system. It is commonly used in platforms that need to run user-supplied or third-party scripts without exposing the server to risk. The discovery of these flaws fundamentally undermines that security guarantee. What the Vulnerabilities Allow All twelve flaws share a common and critical outcome: they enable sandbox escape, meaning an attacker can break out of the isolated environment and execute arbitrary code directly on the host machine. Several of the vulnerabilities...

A high-severity vulnerability was disclosed in the AI-powered development environment Cursor, exposing developers to arbitrary code execution through malicious Git repositories. The flaw, tracked as CVE-2026-26268 with a severity score of 8.1, demonstrates how modern AI-assisted development tools can introduce new attack surfaces when combined with traditional software mechanisms such as version control systems. The vulnerability allows attackers to execute code on a developer’s machine simply by convincing them to clone a specially crafted repository. This significantly lowers the barrier for exploitation, as cloning repositories is a routine and trusted operation in software development workflows. Once the repository is cloned, hidden malicious logic embedded within Git configurations can be triggered automatically without requiring additional user interaction. At the core of the issue is the interaction between Cursor’s AI agent and Git’s built-in features, particularly Git hooks....

Cybersecurity authorities including CISA and the UK’s National Cyber Security Centre disclosed a highly sophisticated malware campaign involving a custom Linux-based backdoor known as FIRESTARTER. The malware specifically targets Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) devices, which are widely deployed as critical network perimeter defenses in enterprise and government environments. The discovery followed a forensic investigation into a breach affecting a U.S. federal agency, revealing that attackers had maintained long-term access to firewall infrastructure even after security patches were applied. The FIRESTARTER backdoor is designed to provide attackers with persistent remote access and full control over compromised devices. Unlike typical malware that resides on endpoints, this implant operates directly within the firewall system itself, effectively turning a core security control into an attack platform. By embedding within the LINA process, wh...
