peertube-plugin-poc-markernpm
peertube-plugin-poc-marker is a confirmed malicious npm package (MAL-2026-15817) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in peertube-plugin-poc-marker (npm)
What this malware does
index.js runs id; uname -a; hostname; date -u; ls -d /var/www/peertube via execSync when PeerTube invokes the plugin's register() hook, then POSTs the combined stdout as JSON to the hardcoded bare-IP collector http://103.38.237.204:8444/poc over plaintext HTTP. The same reconnaissance output is also written into a poc_proof plugin setting registered with private: false, providing a second read-back channel via the PeerTube public settings API. The destination host is not configurable, is unrelated to the plugin's declared PeerTube purpose, and captures the host's user, kernel, hostname, and PeerTube install path from the server on which the plugin is loaded.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for peertube-plugin-poc-marker (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging peertube-plugin-poc-marker across your stack and pipelines.
If you installed it — respond
Remove peertube-plugin-poc-marker 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.
Did it already run?
If peertube-plugin-poc-marker 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.
How O3 protects you
O3 blocks peertube-plugin-poc-marker 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.
