Packet Investigation
PACKET INVESTIGATION
  • Packet crafting
    • Creating specific network packets to gather information or carry out attacks
    • Tools - netcat, nc, ncat, hping
  • Packet inspection
    • Capturing and analyzing network packets
    • Wireshark
INSPECTING TARGETS
  • Fingerprinting
    • Determining OS type and version a target is running
  • Cryptography
    • Inspecting certificates
EVESDROPPING
  • RF communication monitoring

  • Sniffing

    • Intercepting packets and inspecting their contents
    • Wired
      • Wireshark and tcpdump
    • Wireless
      • Aircrack-ng
QUICK REVIEW
  • netcat, nc, ncat, and hping can all help craft packets
  • Crafted packets can help determine where and what a target is
  • Wireshark is a common packet capture and inspection tool
  • Fingerprinting tells you what operation systems your targets are running
DEMO

Wireshark

  • Wireshark allows you to inspect network traffic
  • Useful to see what is being sent between nodes
