The behavior is automatic and unrelated to a PayPal library's stated function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-26T17:39:42.354Z - **Finished:** 2026-07-26T17:40:12.775Z - **Download time:** 510 ms - **Static scan time:** 6 ms - **AI review time:** 29905 ms - **Total time:** 30421 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package triggers host-fingerprint collection and external transmission. The behavior is automatic and unrelated to a PayPal library's stated function. - **Trigger:** npm preinstall - **Impact:** Discloses host identity, home path, and DNS configuration to an external host. - **Evidence paths:** package.json, index.js, gpaas-paypal-28.0.0.tgz - **Review source:** ai\_review - **Reviewed:** 2026-07-26T17:40:12.775Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** host fingerprint exfiltration via HTTPS POST - **Attack narrative:** npm executes index.js before installation. It collects local machine metadata and DNS resolver configuration, then sends it to an external OAST endpoint without user action or package-aligned purpose. - **Rationale:** Source confirms unconsented install-time host-data exfiltration to an external endpoint. This is concrete malicious behavior, not a scanner-only inference. - **Files touched:** package.json, index.js, gpaas-paypal-28.0.0.tgz - **Network endpoints:** https://t4ygm1p2e1grblohe7f7nlf0krqjef24.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 path, and DNS servers., index.js POSTs the collected host fingerprint to an external OAST host during installation., Nested tarball contains the same index.js behavior. - **Evidence against:** No credential-file reads, shell execution, or payload loading were found. ## Public findings ### 1.
