Joel Lohr's workstation (DF-JOEL2, 192.168.0.143) compromised via phishing email to personal Yahoo account. Attacker "Angel Raya" deployed ScreenConnect C2 backdoors. M365 account also compromised from Turkey/UK/Germany.
Attacker
- C2: 80.76.49.18 and 45.88.91.99 (AS399486, Virtuo, Montreal QC) - SUSPENDED by host

- IC3 complaint: 1c32ade367084be9acd548f23705736f
Remediation
- C2 IPs blocked at UDM firewall (iptables - need permanent rules in UniFi UI)
- 3 rogue ScreenConnect clients uninstalled
- jlohr AD password reset, M365 sessions revoked
- 32 machines scanned clean, 28 unreachable (offline)
- No lateral movement detected
MFA Rollout
- 3 CA policies deployed (report-only until April 4, 2026):
- Require MFA (skip from office IP 67.206.163.122)
- Block foreign sign-ins (US only, MFA-Travel-Bypass group for exceptions)
- Block legacy auth
- 19/38 users MFA-ready, 19 need to register

- Auto-reply directs contacts to Dan Center (dcenter@dataforth.com)
- Account should be disabled after retirement
Why: Active security incident requiring immediate response. How to apply: Monitor CA policies in report-only mode, enforce April 4. Check 28 offline machines when available. Add C2 IPs to permanent UDM block list.
