SolarPuttyDecrypt

During a recent Red Team engagement, I was able to become domain admin on the client’s network; I decided to investigate further into the “sys admin” workstations and management network in order to recover more information about the network topology and assets, dumping more password and gaining access to firewalls/switches and servers’ VLANs. Enumerating the sysadmin’s workstations, I discovered a windows tool used to connect via SSH.

The CTF was made possible thanks to the sponsorship with Bitdefender that put some licenses for its product as a prize for the first three winners.
