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

| Wednesday, May 4, 2011
sslsnoop dumps live session keys from openssh and can also decrypt the traffic on the fly.

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