MAL-2026-14434 Malicious code in openai-pr-reviewer (npm)

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.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
