Official description
[email protected] declares a preinstall lifecycle script in package.json that executes
node -e to perform an HTTP GET to a unique subdomain of oastify.com (Burp Suite Collaborator): http://fyhmr907kt8qphysiu67m1p00r6iu8ix.oastify.com. This fires automatically on npm install, confirming arbitrary code execution on the installer's host and leaking the installer's public IP and DNS resolver metadata via the unique subdomain lookup to the attacker-controlled collaborator endpoint. The package's self-declared 'Mozilla bug bounty PoC' framing does not change the behavior: any consumer who installs this version triggers the out-of-band callback. The version number 99.9.9 is also consistent with a dependency-confusion / typosquat probe against an internal package name.What should I do about MAL-2026-13442?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
