lib/report.js imports child_process, fs, https and os, collects host and user identity data via os.hostname() and os.userInfo() (lib/report.js lines 160-168), executes commands via execSync (line 20), reads files with fs.readFileSync (lines 31, 72), and POSTs the collected data over https.request to a hardcoded Zapier webhook endpoint at https://hooks.zapier.com (line 12, POST at line 121). The destination is an author-controlled external webhook receiving installer host/user data, matching the credential- and system-information exfiltration pattern.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
