Analysis

The package oauth-connect@0.1.1 executes a preinstall script (node index.js) that performs system reconnaissance on the installer's machine and exfiltrates the data. It collects: hostname, username, home directory, DNS server list, the contents of /etc/passwd, and the contents of /etc/hosts. All collected data is sent via HTTPS POST to f3js0y9srl22itqjffo9jbl8mzswgm4b[.]oastify[.]com (a Burp Collaborator exfiltration endpoint). The package has no legitimate functionality and only exists to exfiltrate system information upon installation.
