## [WARNING] Security History — 2019 TrickBot Incident
**This section must be reviewed before any domain-level changes.**
### Background
In December 2019, TrickBot infected UC2-SERVER (the domain controller). A hidden SYSTEM scheduled task named "System Health Application" (boot trigger + every 12 minutes, RunLevel HighestAvailable) launched a module loader from the SYSTEM profile. The launcher EXE was already gone by the time of discovery; the task had been failing every run since with error `0x80070002` (FILE_NOT_FOUND). The TrickBot module folder remained intact under the SYSTEM profile:
`C:\Windows\system32\config\systemprofile\AppData\Roaming\syshealth\`
Modules present: `injectDll64`, `pwgrab64`, `psfin64`, `importDll64`, `tabDll64`, `mwormDll64`, `mshareDll64`, `networkDll64`, `NewBCtestnDll64`, plus `dinj`/`dpost`/`sinj` config files and `settings.ini`.
WIN-709JUVCJ2DQ was swept clean — no TrickBot artifacts found.
### Remediation (2026-06-02)
All cleanup was done read-only first, then gated on explicit client confirmation before any writes (DC-safety protocol):
1. Quarantined the module folder: `C:\Quarantine\syshealth-trickbot-20260602-170235\`
2. Deleted the scheduled task "System Health Application"
3. Removed the original folder `...syshealth\`
Quarantine copy is preserved at `C:\Quarantine\syshealth-trickbot-20260602-170235\` as an IR record.
No active C2 traffic was expected — the launcher had been gone for years and the task was failing continuously.
**No free Ryuk decryptor exists.** A reported "crypto" folder of encrypted data could not be located on either server; client concluded it was misremembered.
### [OPEN — CRITICAL] KRBTGT / Domain Credential Reset
**pwgrab64 (credential theft module) ran on a domain controller in 2019.** This means domain credentials, service account passwords, and the KRBTGT hash were potentially exposed at that time. Standard post-DC-compromise IR requires:
- Double-rotation of the KRBTGT password (with a DC replication interval between rotations)
- Reset of all domain user passwords and service account passwords
**Status: UNCONFIRMED.** Whether a post-incident credential/KRBTGT reset was performed in 2019 or afterward has not been verified with the client. Until confirmed, the residual risk is an unrotated KRBTGT on a domain that had a credential-theft module running with SYSTEM privileges on the DC.
**Action required:** Ask the client or review any 2019/2020 IT records. If the reset was never done, execute it during a scheduled maintenance window.

### MSP360 "Ucryo Files" Plan (UC2-SERVER)
| Field | Value |
|---|---|
| Plan name | "Ucryo Files" |
| Plan ID | `5a44fc46-ca94-4095-a645-889eaf754389` |
| Account | richard@ucryo.com |
| Target | Backblaze B2 (api001.backblazeb2.com) |
| Vault | `msp-tools/msp360-api.sops.yaml` (shared MSP360 API creds) |
**Backblaze TLS failure — fixed 2026-06-02.**
UC2-SERVER (Windows Server 2012 R2) was failing TLS negotiation to Backblaze. Root cause: the 64-bit .NET TLS registry keys were unset, which on legacy OS (2012 R2 / Win7-8 era) prevents .NET from negotiating TLS 1.2. First secure-channel error logged 2025-10-15; escalated to hard-failing by 2026-06-02.
Fix applied to UC2-SERVER:
- `HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319` — `SchUseStrongCrypto=1`, `SystemDefaultTlsVersions=1` (DWORD)
- `HKLM\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319` — same two keys
- Restarted "Online Backup Service" and "Online Backup Service Remote Management"
Post-fix verification: `cbb plan -r "Ucryo Files"` returned "Plan is started"; zero secure-channel errors in 5-minute window; scanned 474.9 GB, uploaded 2.15 GB.
**Note:** This fix is legacy-OS-specific. Do NOT apply it fleet-wide — modern OS (Server 2016/2019/2022, Win10/11) already negotiates TLS 1.2 by default; the missing keys are benign on those platforms.
WIN-709JUVCJ2DQ has Veeam installed. All four primary Veeam services (VeeamBackupSvc, VeeamCatalogSvc, VeeamCloudSvc, VeeamMountSvc) were stopped at baseline time. Confirm Veeam job status and why services are stopped. (verify)

## Diagnostic Baselines — 2026-06-02
Baselines collected UTC 2026-06-03T00:35 – 00:54 (sequential run after a parallel run caused agent interruptions under concurrent load). Raw JSON snapshots are immutable at `clients/ucryo/onboarding-baselines/`.
### Per-Host Summary
| Host | Grade | Criticals | Warnings | Standout Findings |
|---|---|---|---|---|
| UC2-SERVER | RED | 1 | 5 | CRITICAL: SMBv1 enabled (WannaCry/EternalBlue vector). Defender cmdlet unavailable (Server 2012 R2). RDP enabled. 3 stopped auto-start services (AD CS, IIS, ShellHWDetection). 36.5-day uptime, reboot pending. BitLocker unavailable (verify). 12 local admins. EOL OS (build 9600 not in map). |
| WIN-709JUVCJ2DQ | RED | 2 | 4 | CRITICAL: SMBv1 enabled. **CRITICAL: E: drive at 4.1% free (40.4 GB of 983.6 GB) — urgent.** Defender unavailable. RDP enabled. Veeam services stopped. Not domain-joined (WORKGROUP). 36.5-day uptime. EOL OS. |
| DESKTOP-PMML1JC | RED | 3 | 3 | CRITICAL: BitLocker off (laptop). CRITICAL: 3 disk errors in 14 days. CRITICAL: Domain secure channel broken. 2 pending patches. |
| KIRBY | RED | 2 | 4 | CRITICAL: **BitLocker OFF (laptop — highest data-at-rest risk).** CRITICAL: Win10 22H2 EOL (2025-10-14). 4 pending patches. RDP enabled. Reboot pending, 35-day uptime. |
| gromit | RED | 1 | 5 | CRITICAL: Win10 22H2 EOL. BitLocker off (desktop). 9 pending patches. RDP enabled. Group Policy Client stopped. |
| hobbes | RED | 2 | 5 | CRITICAL: BitLocker off (laptop). CRITICAL: Win10 22H2 EOL. Unexpected shutdown + disk error in 14 days. RDP enabled. |
| hoborg | RED | 3 | 5 | CRITICAL: BitLocker off (laptop). CRITICAL: Win10 22H2 EOL. **CRITICAL: Toshiba SSD SMART Warning (wear=100%) — replace immediately.** Dual AV (Defender + SentinelOne — possible conflict). RDP enabled. |
| lilo | RED | 2 | 5 | CRITICAL: BitLocker off (laptop). CRITICAL: Win10 22H2 EOL. 82-day uptime. RDP enabled. Group Policy Client + TPM Provisioning stopped. |
### Fleet-Wide Patterns
- All 8 hosts graded RED.
- SMBv1 enabled on both servers (WannaCry/EternalBlue vector — disable before enabling any internet-facing services).
- Win10 22H2 EOL on all 6 workstations (EOL 2025-10-14, no further security patches).
- BitLocker absent on all 5 laptops (KIRBY, DESKTOP-PMML1JC, hobbes, hoborg, lilo) and the DESKTOP-PMML1JC. Servers have BitLocker status UNKNOWN (cmdlet unavailable on 2012 R2).
- RDP enabled on all 8 hosts — confirm firewall restriction to internal/VPN only.
- No LAPS on servers. LAPS registry key present on workstations.
- No backup agent on any workstation.

## Open Items / Follow-ups
| Priority | Item | Notes |
|---|---|---|
| CRITICAL | Confirm 2019 KRBTGT/domain credential reset | pwgrab64 ran on the DC — if reset never done, this is the primary residual risk. |
| HIGH | hoborg SSD replacement | Toshiba SMART Warning, wear=100%. Data backup first. |
| HIGH | WIN-709JUVCJ2DQ E: drive space | 4.1% free (40.4 GB). Identify what is consuming the volume and free/expand. |
| HIGH | Disable SMBv1 on UC2-SERVER and WIN-709JUVCJ2DQ | WannaCry/EternalBlue vector. `Set-SmbServerConfiguration -EnableSMB1Protocol $false` + remove feature. |
| HIGH | BitLocker on all 5 laptops | KIRBY highest priority (domain-joined laptop, unencrypted, mobile). Escrow recovery keys. |
| HIGH | Win10 22H2 EOL on 6 workstations | Feature update or OS upgrade required (EOL 2025-10-14). |
| MEDIUM | DESKTOP-PMML1JC domain secure channel | Run `Test-ComputerSecureChannel -Repair` or rejoin. |
| MEDIUM | Veeam services stopped on WIN-709JUVCJ2Dq | VeeamBackupSvc/CatalogSvc/CloudSvc/MountSvc all stopped — confirm Veeam job health. |
| MEDIUM | RDP exposure review — all 8 hosts | Confirm RDP is restricted to VPN or specific source IPs; not exposed to internet. |
| MEDIUM | hoborg dual AV (Defender + SentinelOne) | Verify intended AV; remove one to prevent conflicts. |
| LOW | UC2-SERVER stopped services | AD CS, IIS Admin, ShellHWDetection stopped — review if these should be running. |
| LOW | LAPS not deployed on servers | Deploy Windows LAPS or legacy AdmPwd to UC2-SERVER and WIN-709JUVCJ2DQ. |
