When to Use
- EDR or antivirus detects malware execution on one or more endpoints

- Threat intelligence indicates a malware campaign targeting the organization's industry
- Network monitoring detects beaconing traffic consistent with known malware C2 patterns
- A file detonation in a sandbox returns a malicious verdict
Do not use for analyzing malware samples in a research context; use dedicated malware analysis procedures for reverse engineering.
Prerequisites
- EDR platform with process tree visibility and host isolation capability
- Malware sandbox environment (Cuckoo, ANY.RUN, Joe Sandbox, Hybrid Analysis)
- Access to threat intelligence platforms for malware family identification (VirusTotal, MalwareBazaar)
- Forensic imaging tools for evidence preservation (FTK Imager, KAPE)
- Clean system images or gold images for endpoint rebuild
- MITRE ATT&CK framework reference for technique mapping
