Network Forensics with Wireshark
Analyze PCAP files for C2 beaconing, credential theft, data exfiltration, and protocol anomalies.
Network Forensics Overview
Network forensics analyzes captured packet data (PCAP files) to reconstruct network-level attacker activity: lateral movement, C2 communication, credential theft, data exfiltration, and protocol anomalies invisible in host-based forensics.
Capturing Traffic
Collect network evidence with Wireshark (interactive), tcpdump (CLI), or dedicated network taps. Deploy span ports or network taps on critical segments before incidents occur. Retrospective analysis requires pre-existing capture infrastructure.
