faceplate-docsnpm
faceplate-docs is a confirmed malicious npm package (MAL-2024-2355) that opens a backdoor for remote access (malicious versions 1.0.0, 99.9.9, 99.9.10). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in faceplate-docs (npm)
What this malware does
[email protected] runs index.js from a postinstall hook that collects the installer's OS username, current working directory, hostname, and local IPv4 address and POSTs them as JSON to a hardcoded anonymous collector at https://webhook.site/f9bff304-3053-4d54-be05-86537267514a. The beacon fires automatically on npm install without any user interaction. The package name plus implausibly high version (99.9.10) and the recon-only payload are characteristic of a dependency-confusion probe designed to identify internal build environments that mistakenly resolve a private package name from the public registry.

Detection & response playbook
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for faceplate-docs (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging faceplate-docs across your stack and pipelines.
If you installed it — respond
faceplate-docs establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If faceplate-docs 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 faceplate-docs 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.

Detect & block this
O3 blocks faceplate-docs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
