    Malicious Package

    @zynkit/jwtbytes is a malicious package. This package contains malicious code and is part of a coordinated npm supply-chain campaign. It ships an obfuscated postinstall payload that downloads and executes a Rust-compiled infostealer binary.

    Impact

    The infostealer targets crypto wallets, browser credentials, cloud tokens, SSH keys, and developer credentials (npm, .env, GitHub/PyPI tokens). It installs persistence via a disguised systemd service and exfiltrates data over Telegram or HTTP. Some versions trigger at runtime, allowing the payload to survive --ignore-scripts.

    Note

    1. This package is part of a larger campaign, involving many packages published from disposable @wshu.net accounts.

    2. This actor has also been linked to attempts to compromise AI-powered workflows.

    3. Malicious versions were hidden behind scrubbed latest tags, so treat all versions as untrusted.

    How to fix Malicious Package?

    Avoid using all malicious instances of the @zynkit/jwtbytes package.
