Supply chain attacks affect PyPI/npm/crates.io, with over 34 malicious packages targeting cryptocurrency and AI developers

According to Slow Fog's disclosure, the security agency MistEye detected a cross-registry supply chain attack incident, where attackers targeted developers in the fields of cryptocurrency, DeFi, Solana, Sui/Move, and AI by publishing malicious packages on npm, PyPI, and crates.io. This attack activity includes more than 34 malicious packages and over 384 related versions. The attackers may steal cryptocurrency wallets, SSH keys, cloud credentials, GitHub/AWS tokens, browser data, environment variables, and developers' confidential information.

Some of the malicious payloads also attempted to achieve persistence through .cursorrules, CLAUDE.md, Git hooks, shell hooks, cron, systemd, and SSH. Developers are advised to immediately remove the affected packages, isolate the affected systems, retain logs, rotate exposed credentials, rebuild CI environments and developer machines from clean images, and review GitHub, cloud services, SSH, and wallet activity logs.
