A complete write-up must include actionable data for defenders: C2 URLs, IP addresses, and User-Agent strings.
Specific Registry paths, unique file mutexes, and dropped file paths. Summary of Risk
Often .ini , .json , or .dat files that contain Command & Control (C2) IP addresses or encryption keys. 3. Behavioral Analysis (Dynamic)
