Windows Anti-Forensics: Erasing Tracks to Evade Blue Team in Red Team Ops
In red team engagements, persistence is only half the battle evasion is the other. A single overlooked log, cached DNS entry, or recoverable deleted file can unravel an entire operation. This post details a battle-tested sequence of native Windows commands designed to systematically erase forensic artifacts while minimizing noise and maximizing coverage.
These commands target:
Red Ghost OpsFree spaceRed Ghost Ops (unrecoverable deletion)
Red Ghost OpsEvent logsRed Ghost Ops
Red Ghost OpsDNS cacheRed Ghost Ops
Red Ghost OpsBrowser artifactsRed Ghost Ops
Red Ghost OpsNTFS metadata (USN Journal)Red Ghost Ops
Red Ghost OpsTemp files, prefetch, print spoolRed Ghost Ops
Red Ghost OpsTelemetry and error reportingRed Ghost Ops
Warning (Red Team Disclaimer): Use only in authorized engagements. These actions are irreversible and may trigger EDR alerts if not executed with proper OPSEC.
1. Overwrite Free Space – Prevent File Recovery
cipher /w:C:\
Purpose: Overwrites all free space on C:\ with 0x00, 0xFF, and random data (3-pass pattern).
Impact: Deleted files become unrecoverable by forensic tools (Recuva, Autopsy, etc.).
Risk: High I/O and CPU usage. Slow (hours on large drives). No effect on active files.
Blue Team Counter: Volume Shadow Copies (VSS) may still contain prior snapshots.
2. Flush DNS Cache – Break Local Resolution Trails
ipconfig /flushdns
Purpose: Clears locally cached DNS resolutions.
Impact: Forces fresh DNS queries—removes evidence of C2 domains accessed.
Risk: Low. May cause brief connectivity delays.
Blue Team Counter: Network logs (firewall, DNS server) remain untouched.
3. Clear System Event Log
wevtutil cl System
Purpose: Permanently deletes the System event log.
Impact: Removes boot, driver, service, and security events.
Risk: Irreversible. Breaks incident timeline reconstruction.
Blue Team Counter: SIEM ingestion prior to clear; Event Log backup services.
4. Wipe IE/Edge Legacy Browser Artifacts
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255
Purpose: Deletes history, cookies, cache, passwords, form data from IE/Edge (legacy).
Impact: Covers web-based C2 (e.g., Empire over HTTP).
Risk: Low. Affects only IE/Edge components.
Blue Team Counter: Modern Edge (Chromium) uses different storage—use browser-specific tools.
5. Delete NTFS USN Change Journal
fsutil usn deletejournal /d /n C:
Purpose: Erases the USN Journal ($UsnJrnl), which tracks file creation/modification/deletion.
Impact: Breaks incremental backups, file indexing (Search, antivirus), and timeline analysis.
Risk: High—may corrupt backup chains or trigger AV rescans.
Blue Team Counter: Journal may auto-recreate on next change; prior entries lost.
6. Clear User Temp Files
del /f /s /q %TEMP%\*.*
Purpose: Force-deletes all files in the user’s temp directory.
Impact: Removes payloads, scripts, or tools staged in %TEMP%.
Risk: Low–moderate. Running apps may crash if files are in use.
Blue Team Counter: File access monitoring (Sysmon Event ID 11) may log before deletion.
7. Disable Hibernation & Delete hiberfil.sys
powercfg /hibernate off
Purpose: Removes hiberfil.sys (size ≈ RAM), a common forensic goldmine (contains RAM dump).
Impact: Frees space; prevents hibernation.
Risk: Reversible (powercfg /hibernate on). Disables Fast Startup.
Blue Team Counter: None if executed post-exfiltration.
8. Reset TCP/IP Stack
netsh interface ipv4 reset
Purpose: Clears custom IP/DNS settings, proxy configs, and interface state.
Impact: Useful after using static routes or proxychains.
Risk: Requires reconfig or reboot. May break VPNs.
Blue Team Counter: Netflow or interface config logs.
9. Clear Print Spooler Queue
del /q /f /s %systemroot%\System32\spool\PRINTERS\*
Purpose: Deletes pending print jobs (often contain sensitive docs or stagers).
Impact: Cancels all print jobs.
Risk: Low. May require spooler restart if files locked.
Blue Team Counter: PrintNightmare or spooler monitoring.
10. Disable Telemetry
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection" /v AllowTelemetry /t REG_DWORD /d 0 /f
Purpose: Sets telemetry to 0 (disabled) via GPO-style registry key.
Impact: Reduces diagnostic data sent to Microsoft.
Risk: Low. May not apply on Home editions.
Blue Team Counter: Central telemetry collection (e.g., OMS, Defender ATP).
11. Clear Prefetch Files
del /q /f /s %SystemRoot%\Prefetch\*.*
Purpose: Deletes .pf files that record application execution paths and timestamps.
Impact: Removes evidence of tool usage (e.g., mimikatz.exe).
Risk: Temporary performance hit on app launch.
Blue Team Counter: Prefetch parsing (e.g., PECmd, WinPMEM).
12. Disable Windows Error Reporting
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows Error Reporting" /v Disabled /t REG_DWORD /d 1
Purpose: Stops crash dumps and error reports.
Impact: Prevents upload of memory dumps containing keys or tokens.
Risk: Low. Hinders post-exploitation analysis.
Blue Team Counter: Local WER queue before upload.
Execution Order & OPSEC Tips
cipher /w:C:\
ipconfig /flushdns
wevtutil cl System
RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255
fsutil usn deletejournal /d /n C:
del /f /s /q %TEMP%\*.*
powercfg /hibernate off
netsh interface ipv4 reset
del /q /f /s %systemroot%\System32\spool\PRINTERS\*
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection" /v AllowTelemetry /t REG_DWORD /d 0 /f
del /q /f /s %SystemRoot%\Prefetch\*.*
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows Error Reporting" /v Disabled /t REG_DWORD /d 1
OPSEC Recommendations:
Run as SYSTEM (via psexec -s or token impersonation).
Disable EDR hooks first (if possible).
Avoid GUI—use cmd or PowerShell with -WindowStyle Hidden.
Stagger execution to avoid I/O spikes.
Check VSS first: vssadmin list shadows → delete if needed (/for=C:).
What This Doesn’t Cover
Memory forensics (use Rundll32.exe comsvcs.dll MiniDump countermeasures separately)
Modern Edge/Chrome (use Get-Process msedge | Stop-Process + clear %LocalAppData%\Microsoft\Edge)
Sysmon/Event Forwarding
MFT/$LogFile (use fsutil behavior set disablecompression 1 + ntfsinfo)
Final Notes
This sequence turns a compromised host into a forensic black hole. Blue team will see:
No event logs
No prefetch
No DNS history
No recoverable deleted files
Red Team Pro Tip: Combine with timestomping, logon spoofing, and AMS1 bypass for full-spectrum evasion.
Stay ghosted.
