On npm install, postinstall.js executes automatically and collects installer host identifiers (os.hostname(), os.userInfo().username) plus public IP/geo data fetched from ip-api.com (city, region, country, ISP, org), then transmits them as query-string parameters over plain HTTP to a hardcoded Burp Collaborator subdomain at p1r2d74iwjk057raam6myf7e258wzkt8i.oastify.com... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-08T17:21:18.478Z - **Finished:** 2026-07-08T17:25:10.588Z - **Download time:** 255 ms - **Static scan time:** 7 ms - **AI review time:** 231848 ms - **Total time:** 232110 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package contains an install-time callback that harvests host/user and IP geolocation data and sends it via DNS to an OAST domain. The name guard mismatch may prevent ordinary gen-ai-opt-in installs from reaching the payload, but the source intent is unconsented install-time data exfiltration. - **Trigger:** npm postinstall lifecycle when guard conditions match - **Impact:** Leaks username, hostname, public IP, city/region/country, ISP, and org to an attacker-controlled callback domain. - **Evidence paths:** package.json, postinstall.js, readme.md - **Review source:** ai\_review - **Reviewed:** 2026-07-08T17:25:10.588Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host/user/IP geo collection with DNS exfiltration - **Rationale:** Source inspection shows a lifecycle script whose primary behavior is collecting local/user and network identity data and exfiltrating it over DNS. The mismatched package-name guard reduces trigger certainty for this exact package name but does not make the embedded install-time exfiltration logic benign. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** package.json, postinstall.js - **Network endpoints:** https://ip-api.com/json/, p1r2d74iwjk057raam6myf7e258wzkt8i.oastify.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for AI warning decision:** package.json defines postinstall: node postinstall.js and main points to postinstall.js, postinstall.js collects public IP geo data from https://ip-api.com/json/, postinstall.js collects os.hostname() and os.userInfo().username, postinstall.js encodes collected values into a DNS lookup to p1r2d74iwjk057raam6myf7e258wzkt8i.oastify.com, readme.md says "Takeover By lobo" with no legitimate package purpose - **Evidence against:** postinstall.js exits unless npm\_lifecycle\_event and npm\_package\_name are set, guard checks npm\_package\_name === 'ai-gen-ai-opt-in', which does not match package.json name gen-ai-opt-in, No file writes, child\_process, eval, native binaries, or persistence found ## Affected versions and remediation This report applies to gen-ai-opt-in@99.0.0. - Avoid installing gen-ai-opt-in@99.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
