Networking Skill

Quick Workflow

CopyProgress:
- [ ] Get protocol overview (tshark -z io,phs)
- [ ] Search strings for flag pattern
- [ ] Export HTTP/SMB objects
- [ ] Follow interesting streams
- [ ] Check for credentials/exfiltration
- [ ] Extract flag

Quick Analysis Pipeline

Copy# 1. Basic info
capinfos capture.pcap
file capture.pcap

# 2. Protocol hierarchy
tshark -r capture.pcap -z io,phs

# 3. Conversations
tshark -r capture.pcap -z conv,tcp

# 4. Quick string search
strings capture.pcap | grep -i flag
tshark -r capture.pcap -Y "frame contains flag"
