More Information on Miasma Leak

Image
  “Worm Code Leaked” — What happened? 1. The latest incident (June 2026) A self‑replicating malware worm called “Miasma” had its source code leaked publicly on GitHub . The code appeared in repos named “Miasma-Open-Source-Release” across compromised developer accounts. Researchers believe the leak was intentional , not accidental. The malware is part of a broader software supply‑chain attack campaign . 2. What the worm actually does “Miasma” isn’t just basic malware — it’s advanced and dangerous: Steals credentials (cloud tokens, API keys, GitHub access, etc.) Targets developers and build systems (CI/CD pipelines) Infects packages on: npm PyPI RubyGems Uses stolen access to inject itself into legitimate repositories Spreads automatically (worm behavior) without needing user action In short: one infected developer account can cascade into hundreds of compromised projects . 3. Real-world impact This isn’t theoretical — it already caused major damage: 73 Microsoft GitHub reposito...

Miasma worm is a self‑replicating supply‑chain malware campaign and Mitigation

Image
The Miasma worm is a self‑replicating supply‑chain malware campaign that struck 73 Microsoft GitHub repositories across four major Microsoft organizations — Azure, Azure‑Samples, Microsoft, and MicrosoftDocs — in early June 2026. It represents one of the most significant escalations in modern software‑supply‑chain attacks, especially because it targets AI‑assisted developer tools rather than traditional package‑install mechanisms. What Happened A malicious commit was pushed into the Azure/durabletask repository using previously compromised contributor credentials . GitHub responded by disabling 73 Microsoft repositories in an automated sweep lasting 105 seconds . The commit did not modify source code. Instead, it added configuration files designed to auto‑execute a 4.3–4.6 MB obfuscated JavaScript payload when opened in: Claude Code Gemini CLI Cursor Visual Studio Code npm test script Why This Attack Is Different Traditional supply‑chain attacks rely on poisoning package re...

Anthropic Project Glasswing

  Anthropic Expands Project Glasswing (June 2026) Anthropic has significantly expanded its Project Glasswing cybersecurity initiative , marking one of the most important recent developments in AI-driven security. What Project Glasswing Is Project Glasswing is a collaborative cybersecurity program launched in April 2026 that uses Anthropic’s powerful AI model, Claude Mythos Preview , to uncover and fix software vulnerabilities. The model can detect and even chain together vulnerabilities far beyond traditional tools. It has already found thousands of flaws across operating systems, browsers, and infrastructure software . Because it could also be misused for cyberattacks, access is strictly controlled and not public . The overarching goal: use advanced AI defensively to secure critical global infrastructure before attackers gain similar capabilities . What “Expansion” Means In early June 2026, Anthropic announced a major scale-up: +150 new organizations added (from ~50 initially) ...
