  "evidence": "IP 212.181.80.130 is the common thread connecting the attack. This IP was used by crispy-octopus to publish packages with postinstall scripts ([email protected], [email protected]), by fuzzy-crab to publish [email protected] with postinstall, to create dusty-turtle account, and for failed login attempts on crispy-octopus. sandy-ray has ZERO audit log events despite being a registered maintainer who published [email protected]. sandy-ray IP 205.94.178.34 also has zero events. sandy-ray uses anonymous proton.me email. clever-tern has no 2FA and their credentials were used to publish [email protected] and [email protected] (flagged packages) with no corresponding audit trail entries from clever-terns normal IPs. All postinstall scripts exfiltrate environment variables and hostname to telemetry-cdn.sh or telemetry-cdn.io domains.",
  "methodology": "1. Started with GET /security/flagged to identify the 3 flagged packages. 2. Examined each flagged version to find publishers (clever-tern, sandy-ray) and malicious postinstall content. 3. Used get_suspicious_patterns to find shared IP 212.181.80.130 between crispy-octopus and fuzzy-crab. 4. Used compare_ips to confirm the IP sharing. 5. Got detailed timelines for all suspect maintainers. 6. Used get_ip_activity on 212.181.80.130 to find all events from attacker IP including dusty-turtle creation, failed logins, bulk publish, and ownership transfer. 7. Checked sandy-ray audit trail (empty) and IP (empty). 8. Cross-referenced maintainer.add and account.create events. 9. Verified all packages for postinstall scripts to find additional compromised versions beyond the flagged three.",
