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 @matjp/dvi-decode (version 0.4.101). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @matjp/dvi-decode across your stack and pipelines.

  2. If you installed it — respond

    Remove @matjp/dvi-decode 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 @matjp/dvi-decode 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 @matjp/dvi-decode 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
