Summary
Malicious code in wolverinechat (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (6ad1c6bad5ee8d3cb562503b94d5534ba2c98ad5b4854c073e1482d59ab8687e)

package.json declares a preinstall hook that runs index.js during npm install. The script reads /etc/passwd, /etc/hosts, os.hostname(), os.userInfo().username, the user's home directory, dns.getServers(), and package metadata, then POSTs the collected data via HTTPS to the hardcoded subdomain 7ckdbwo9f8dtrg8y36sbe4e8lzrqfg35.oastify.com (Burp Collaborator OAST callback). The exfiltration fires automatically at install time without user interaction.
