# Windows Registry Autorun Forensics

## When to Use
- During triage of a potentially compromised Windows system to identify how malware survives reboots.
- After extracting the registry hives (SAM, SYSTEM, SOFTWARE, NTUSER.DAT) from a forensic disk image for offline analysis.


## Prerequisites
- Forensic image or live access to the affected system(s)
- Forensic workstation with analysis tools (Autopsy, Volatility, Timeline Explorer)
- Chain of custody documentation initiated for evidence handling
- Write-blocker for disk forensics or memory acquisition tool (e.g., DumpIt, WinPmem)

## Workflow

### Phase 1: Identifying Run / RunOnce Keys

```powershell
# Concept: Windows Registry Get-ItemProperty -Path "HKLM:\Software\Microsoft\Windows\CurrentVersion\Run"
Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Run"
```

### Phase 2: Detecting IFEO (Image File Execution Options) Injection

```powershell
# Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options" | Select-Object Name | Where-Object { $_.Name -match "sethc.exe|utilman.exe" }
# ```

### Phase 3: Inspecting Services Registry Keys

```powershell
# Get-ChildItem -Path "HKLM:\SYSTEM\CurrentControlSet\Services" | Where-Object { (Get-ItemProperty $_.PSPath).ImagePath -match "C:\\Users\\|C:\\ProgramData\\" } | Select-Object Name, @{Name="ImagePath"; Expression={(Get-ItemProperty $_.PSPath).ImagePath}}
```

### Phase 4: Offline Analysis using RegRipper

```bash
# # rip.pl -r /mnt/evidence/Windows/System32/config/SOFTWARE -p run
rip.pl -r /mnt/evidence/Users/Bob/NTUSER.DAT -p userinit
```
