Attackers injected malicious code into at least 18 widely used packages \u2014 including <strong>debug<\/strong> and <strong>chalk<\/strong>. These are foundational dependencies with <strong>around two billion combined weekly downloads<\/strong>. The injected malware intercepts cryptocurrency and Web3 transactions in users\u2019 browsers, redirecting funds to attacker wallets without any visual cues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>\u201cs1ngularity\u201d Attack on Nx Build System<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On <strong>26 August 2025<\/strong>, attackers leveraged a compromised GitHub Actions workflow to publish malicious versions of <strong>Nx<\/strong> and its plugins to npm. These packages executed post-install scripts that scanned infected systems for SSH keys, GitHub\/npm tokens, environment variables, cryptocurrency wallet files, and more. Even more disturbing, attackers weaponised developer-facing <strong>AI command-line tools<\/strong>\u2014including Claude, Gemini, and Amazon\u2019s Q\u2014using flags like <code>--yolo<\/code>, <code>--trust-all-tools<\/code> to recursively harvest sensitive data, then exfiltrated it to public GitHub repositories named <code>s1ngularity-repository\u2026<\/code>. The breach is estimated to have exposed <strong>1,000+ developers<\/strong>, <strong>20,000 files<\/strong>, dozens of cloud credentials, and hundreds of valid GitHub tokens, all within just four hours.
