Official description
On
npm install, preinstall.js collects hostname, username, platform, cwd, timestamp, and a full dump of os.networkInterfaces() and HTTP-GETs them as query parameters to a hardcoded Burp Collaborator (oastify.com) endpoint. Errors are silently swallowed (the source comment notes 'Silent fail to avoid detection'). The package's metadata advertises an Oracle JET payment account selector but ships only a 5-line stub for index.js — the only real logic is the install-time beacon. The combination of empty author metadata, generic 'oracle/jet/payment' keywords, hollow main entry, and a recon-only preinstall is consistent with a dependency-confusion probe against an internal Oracle JET package name, with installer host/network topology exfiltrated to the attacker's OAST collector.What should I do about MAL-2026-4635?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
