| Tool | Category | Quick How‑To | |------|----------|--------------| | | Static analysis (metadata, imports, entropy) | Open the .exe, look for suspicious imports (e.g., WinInet.dll , urlmon.dll ). | | Process Explorer | Runtime monitoring | Run the file in a sandbox, then view process tree for hidden child processes. | | Autoruns | Startup persistence check | Search for new entries created after execution. | | RegShot | Registry diff | Take a “before” and “after” snapshot to see what keys changed. | | Cuckoo Sandbox | Automated dynamic analysis | Submit the file and review generated behavior reports. | | Hybrid Analysis / VirusTotal | Cloud‑based multi‑engine scanning | Upload the file; read community comments for context. |
