Detection & response playbook

Malicious package
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for uuu8lgd (10 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging uuu8lgd across your stack and pipelines.

  2. If you installed it — respond

    Remove uuu8lgd from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If uuu8lgd was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks uuu8lgd before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. uuu8lgd on npm has been identified as a malicious package (versions 1.0.1, 1.0.2, 1.0.7, 1.0.10, 1.0.11, 1.0.14, 1.0.17, 1.0.19, and 2 more flagged). It should be removed immediately — do not install or keep it in your dependency tree.
