Official description
[email protected] ships an index.js that is executed via a preinstall lifecycle script on
npm install. The script collects installer-side identifiers — os.hostname(), os.userInfo().username, os.homedir(), process.cwd(), dns.getServers(), and the contents of the package's package.json — and POSTs them over HTTPS to the hardcoded external collector eo1blcdjptwydyq.m.pipedream.net. A source comment ("replace burpcollaborator.net with Interactsh or pipedream") shows the file is a dependency-confusion exfiltration template repurposed as a live payload. The implausibly high version number (100.0.0) is consistent with a dependency-confusion lure intended to override an internal package of the same name during resolution.What should I do about MAL-2026-17215?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
