SLAE – Assignment #3: Egghunter

Assignment #3: Egghunter This time the assignment was very interesting, here the requirements: study an egg hunting shellcode and create a working demo, it should be configurable for different payloads. As many before me, I’ve started my research journey with Skape’s papers: “Searching Process Virtual Address Space”. I was honestly amazed by the paper content, it’s not only very well written and explained but it ‘s mind-blowing. Understanding why and how egg hunter shellcode should be crafted in such tailored way...

SLAE – Assignment #2: Reverse TCP Shell

Assignment #2: Reverse TCP Shell Create a shell_reverse_tcp shellcode that connects back to an IP address, on a specific a port and execute a shell. The IP address and port number should be easy configurable. Again, instead of going for the path of writing a C TCP reverse shell from scratch, I decided to generate a raw Metasploit payload and analyze it with libemu. Analyzing the Shellcode All the code is also available on GitHub. This time the analysis will be a lot shorter...

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....
