It sends collected local-system metadata to an external tracking endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-26T17:33:18.536Z - **Finished:** 2026-07-26T17:33:38.351Z - **Download time:** 255 ms - **Static scan time:** 9 ms - **AI review time:** 19551 ms - **Total time:** 19815 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically executes a host-fingerprinting payload. It sends collected local-system metadata to an external tracking endpoint. - **Trigger:** npm preinstall - **Impact:** Unconsented disclosure of host identity, home-directory path, and DNS configuration. - **Evidence paths:** package.json, index.js, payoutsvettingserv-paypal-28.0.0.tgz - **Review source:** ai\_review - **Reviewed:** 2026-07-26T17:33:38.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** host fingerprinting and HTTPS exfiltration - **Attack narrative:** On npm installation, the preinstall hook invokes index.js. The script fingerprints the host and POSTs the JSON data to an external OAST endpoint without user action or package functionality requiring it. - **Rationale:** This is concrete, unconsented install-time host-data exfiltration, corroborated directly in the manifest and source. - **Files touched:** package.json, index.js, payoutsvettingserv-paypal-28.0.0.tgz - **Network endpoints:** 2y1pgajb8aa05uiq8g9ghu99e0ks8twi.oastify.com/hit ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node index.js\` in preinstall., index.js collects hostname, platform, architecture, home directory, and DNS servers., index.js POSTs collected host data to oastify.com during installation., Nested archive repeats the same preinstall payload. ## Public findings ### 1.
