  "evidence": "1. IP 183.108.227.82 (phantom IP) is the common thread: it created frosty-whale, published malicious packages through stolen tokens from both rocky-ray and rusty-eel accounts, conducted the failed brute-force on rocky-ray, triggered all three security.* audit events, and added frosty-whale as maintainer to net-node.\n2. rocky-ray is the primary compromised maintainer: no 2FA enabled, their token was used to publish malicious versions of salt-log and twine-pool from the phantom IP. Dual-publish events (same version from legitimate IP and phantom IP simultaneously) confirm token theft.\n3. rusty-eel token was also stolen: [email protected] was published from both 111.21.153.250 (rusty-eel's legitimate IP) and 183.108.227.82 (phantom IP) at the same timestamp on Jan 10 — classic dual-publish fingerprint of credential compromise.\n4. frosty-whale created directly from phantom IP on Feb 3: compare_ips and IP activity both confirm the account creation event originated from 183.108.227.82.\n5. Attack vector confirmed by audit events: security.similar_package_registered (typosquat), security.maintainer_added_by_social_engineering, security.contributor_elevated — all from phantom IP, all on Feb 6.\n6. salty-ray (proton.me email, Jan 7 registration, 1 package) appears to be a phantom staging account used to publish [email protected] directly.",
  "methodology": "1. Started with GET /security/flagged to identify initial alert packages. 2. Cross-referenced all flagged package version histories to identify publishers. 3. Pulled full maintainer list and flagged accounts with recent join dates and unusual email domains. 4. Used get_suspicious_patterns to identify rocky-ray as primary anomaly (unusual hours, shared IP, brute force). 5. Used compare_ips to identify phantom IP 183.108.227.82 shared between rocky-ray and rusty-eel. 6. Used get_ip_activity on phantom IP to reconstruct full attack timeline — this revealed dual-publish events, frosty-whale account creation, and all security.* events. 7. Pulled rusty-eel and rocky-ray full timelines to separate legitimate from phantom activity. 8. Identified four compromised packages: the three flagged plus [email protected] confirmed via phantom IP audit event.",
