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. TL;DR SolarPuttyDecrypt is a post-exploitation/forensics tool to decrypt SolarPuTTY's sessions files and retrieve plain-text credentials. It...

VoidSec CTF: Secure the Flag – Writeup
It has been a while since my last blog post, so I’m (finally) writing the write-up of the: VoidSec CTF Secure the flag. 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. This CTF was web based, no binary exploitation nor reverse engineering and/or crypto was involved. Before I dive into deep, let me explain what was the goal of this CTF and why it is...
