: Extract MD5, SHA-1, or SHA-256 hashes of executed binaries. Run these hashes against internal whitelists and external malware repositories. 4. Phase 3: Strategic Pivoting and Scope Expansion effective threat investigation for soc analysts pdf

When endpoint data is insufficient — or when an attacker has evaded endpoint controls — network forensics becomes critical. Tools that provide full packet capture and analysis allow analysts to reconstruct network sessions, detect command-and-control (C2) traffic, and identify data exfiltration. Key network forensic techniques include JA3/JA4 fingerprinting for TLS traffic analysis and protocol analyzers for inspecting application-layer activity.
