Exfiltrates encrypted data via Ethereum dead-drop C2. Malicious payload found in: setup.mjs, math_init.js\nTrigger: preinstall script in package.json\nBehavior: Downloads Bun runtime, executes obfuscated infostealer payload targeting npm/GitHub/AWS/K8s/Vault/Stripe/Slack credentials and sensitive files. Exfiltrates via Ethereum dead-drop C2. Self-propagating worm infects other maintainers packages.\nCompromised versions: 6.3.7, 6.3.8, 6.3.9, 6.3.10, 6.3.11, 6.3.12, 6.3.13, 6.3.14, 6.3.15, 6.3.16, 6.3.17, 6.3.18, 6.3.19, 6.3.20, 6.3.21, 6.3.22, 6.3.23, 6.3.24, 6.3.25, 6.3.26, 6.3.27, 6.3.28, 6.3.29, 6.3.30, 6.3.31, 6.3.32, 6.3.33
