Vidar Stealer 2.0 Delivered via Fake Game Cheats on GitHub

🎮 Acronis TRU found hundreds of GitHub repositories posing as "free" game cheats that deliver the Vidar 2.0 infostealer, warning the true number of malicious repos could be in the thousands. Campaigns begin in game-focused Discord and Reddit communities and use PS2EXE-compiled PowerShell loaders to evade basic detections. Loaders add Windows Defender exclusions, fetch secondary payload URLs from Pastebin linking to GitHub-hosted binaries, and deploy a Themida-packed Vidar executable that establishes persistence via scheduled tasks. The payload then harvests credentials, tokens and files and exfiltrates them through C2 infrastructure masked by Telegram bots and Steam dead-drop resolvers.

GlassWorm Compromise Hits 400+ Repos Across Platforms

🪲 The GlassWorm supply‑chain campaign has resurfaced, compromising 433 packages, repositories, and extensions across GitHub, npm, and VSCode/OpenVSX. Researchers from Aikido, Socket, Step Security and the OpenSourceMalware community link the activity to a single actor using the same Solana address, identical payloads, and shared infrastructure. Malicious commits employ invisible Unicode to hide obfuscated JavaScript that polls the Solana blockchain for memos and downloads a Node.js runtime to execute an information stealer; developers should search for the marker lzcdrtfxyqiplpd and inspect for persistence artefacts.

Malicious Commands in GitHub Codespaces Enable RCE Risk

⚠️Orca Security researchers disclosed multiple attack vectors in GitHub Codespaces that can produce remote code execution simply by opening a malicious repository or pull request. By embedding commands in repository configuration files—specifically .vscode/tasks.json, .vscode/settings.json and .devcontainer/devcontainer.json—an attacker can execute code, exfiltrate tokens and access secrets without further user interaction. Microsoft confirmed the behavior is "by design" and points to trusted-repository controls to limit cross-environment impact.

DevOps & SaaS Downtime: Hidden Costs for Cloud Firms

⚠️ Recent analysis highlights that major DevOps SaaS platforms (e.g., GitHub, Jira, Azure DevOps) experienced widespread incidents in 2024–2025, with critical outages and degraded-service hours increasing sharply year‑over‑year. The piece argues the Shared Responsibility model leaves customers ultimately accountable for their data, and that native provider backups often create single points of failure with limited restore flexibility. It recommends multi‑layered, immutable backups, cross‑restore capability, defined RTO/RPOs, and continuous recovery testing to reduce financial, operational, and compliance risk.

VS Code Forks Suggest Missing Extensions, Risk Supply Chain

⚠️ AI-powered VS Code forks such as Cursor, Windsurf, Google Antigravity and Trae were found recommending extensions that do not exist in the Open VSX registry, creating unclaimed namespaces attackers could register. Koi researcher Oren Yomtov showed that a single click on a suggested install (for example, a placeholder ms-ossdata.vscode-postgresql) can deploy a rogue package, and one placeholder received over 500 installs. Cursor and Google have released fixes, and the Eclipse Foundation removed non-official contributors and tightened registry safeguards. Developers should verify publishers before accepting IDE extension recommendations.

Forked VSCode IDEs Expose Developers to Namespace Hijack

⚠ Forked IDEs based on Microsoft VSCode (such as Cursor, Windsurf, Google Antigravity and Trae) retain hardcoded extension recommendations that point to Microsoft's Visual Studio Marketplace. Because these forks use OpenVSX instead, several recommended publisher namespaces were unclaimed, enabling attackers to register them and publish malicious extensions. Supply-chain researchers at Koi claimed affected namespaces and uploaded inert placeholders while coordinating with the Eclipse Foundation to secure the registry.

Webrat Lures Researchers with Fake GitHub Exploit PoCs

🐀 Attackers are hosting counterfeit proof-of-concept exploit repositories on GitHub to deliver the Webrat backdoor to unsuspecting users. Kaspersky analysts observed polished, likely machine-generated README files that mask a password-protected ZIP; the archive password is hidden in filenames and often missed. Inside are decoy DLLs, batch loaders and executables (e.g., rasmanesc.exe) that disable Windows Defender, escalate privileges, and fetch the real payload from hardcoded C2 servers. The campaign, active since at least September 2025, appears tuned to catch novice researchers and students who analyze PoCs outside isolated environments.

WebRAT Distributed via Fake PoC Exploits on GitHub

🛡️ Kaspersky researchers found WebRAT backdoor being distributed through GitHub repositories that posed as proof‑of‑concept exploits for recently disclosed vulnerabilities. The malicious packages were delivered as password‑protected ZIPs containing a corrupted decoy DLL, a batch script, and a main dropper named rasmanesc.exe that elevates privileges, disables Defender, and downloads WebRAT. All identified repositories have been removed, but developers are urged to verify PoC sources and test untrusted code in isolated environments.

Fake GitHub Repos Deliver PyStoreRAT via HTA/JS Loaders

🛡️ Researchers warn that a wave of malicious GitHub repositories are distributing a newly observed JavaScript-based RAT called PyStoreRAT, delivered via minimal Python/JS loader stubs that fetch and execute remote HTA files through mshta.exe. The deceptive projects — marketed as OSINT utilities, DeFi bots, GPT wrappers, and developer tools — often exhibit non-functional or placeholder interfaces designed to build trust. Once executed, the multi-stage implant can run EXE, DLL, PowerShell, MSI, Python, and HTA modules and deploys a follow-on information stealer, Rhadamanthys. The initial stage also checks for security products such as CrowdStrike and Cybereason to reduce visibility and establishes persistence via a scheduled task masquerading as an NVIDIA update.

Exposed GitHub PATs Enable Access to Cloud Secrets

🔒 Recent research from the Wiz Customer Incident Response Team shows attackers are using exposed GitHub Personal Access Tokens (PATs) to retrieve GitHub Action Secrets and pivot into cloud environments. A read-level PAT can leverage GitHub’s API code search to locate secret references like "${{ secrets.SECRET_NAME }}" — and because those search API calls are not logged, discovery is stealthy. Once obtained, cloud provider credentials let attackers spin up resources, exfiltrate data, install malware, or persist while often evading detection. Organizations should treat PATs as privileged credentials: enforce expiration and rotation, remove cloud secrets from workflows, apply least privilege, and improve monitoring and developer training.
