openai-pr-reviewernpm
openai-pr-reviewer is a confirmed malicious npm package (MAL-2026-14434) 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 openai-pr-reviewer (npm)
What this malware does
The package's preinstall hook runs index.js, which collects the installer's hostname, username, home directory, DNS servers, current working directory, package.json contents, and the contents of /etc/passwd and /etc/hosts, then POSTs them over HTTPS to the hardcoded Burp Collaborator subdomain vjib8dmg59zuxwwymzboy0ymhdn4bvzk.oastify.com. Execution is automatic on npm install via the preinstall lifecycle script, with no user interaction required.

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 openai-pr-reviewer (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 openai-pr-reviewer across your stack and pipelines.
If you installed it — respond
Remove openai-pr-reviewer 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 openai-pr-reviewer 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 openai-pr-reviewer 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.
