Advisory published Updated

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
Search your lockfiles and build artifacts for peertube-plugin-poc-marker (version 1.0.0).
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 installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks peertube-plugin-poc-marker-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
