sslsnoop v0.6 – Dump Live Session Keys From SSH & Decrypt Traffic On The Fly

Prevent Network Security Leaks with Acunetix

sslsnoop dumps live session keys from openssh and can also decrypt the traffic on the fly.

  1. Works if scapy doesn’t drop packets. using pcap instead of SOCK_RAW helps a lot now.
  2. Works better on interactive traffic with no traffic at the time of the ptrace. It follows the flow, after that.
  3. Dumps one file by fd in outputs/
  4. Attaching a process is quickier with –addr 0xb788aa98 as provided by haystack INFO:abouchet:found instance @ 0xb788aa98
  5. how to get a pickled session_state file : $ sudo haystack –pid pgrep ssh sslsnoop.ctypes_openssh.session_state search > ss.pickled
