--- _-= Per source details.

The script contacts https://api.ipify.org to resolve the installer's public IP, reads process.env, and sends data to an `.oast.fun` host — the Project Discovery `interact.sh` out-of-band testing service used as a generic exfiltration sink. On `npm install`, this fires automatically and leaks host identity, network egress IP, and environment variables to an attacker-controlled collector. There is no legitimate reason for a Next.js page utility package to perform host fingerprinting or beacon to an OOB interaction service at install time. ## Source: ossf-package-analysis (ff710fe6d7fd45d98e33a811da127f892b543f920fe244e16f56e71db66c3ebf) The OpenSSF Package Analysis project identified 'private-next-pages' @ 9.0.5 (npm) as malicious.
