Source room: https://tryhackme.com/r/room/airplane Airplane is another tagline-only room at TryHackMe with the description of “Are you ready to fly?” Let’s fly! I am testing on a Kali VM with a VPN connection to TryHackMe. With the VPN connected and room instance launched, I started by running an nmap scan against the target machine. The results…

Expose is a TryHackMe room with the tagline “Use your red teaming knowledge to pwn a Linux machine.” That’s not much in the way of details besides exposing (no pun intended!) that it’s a Linux box, so let’s get straight to nmap and find out what I’m dealing with. The initial nmap scan showed five open…

This is my writeup for the TryHackMe room “Retro” at https://tryhackme.com/room/retro. This room is labeled a “hard” room so I wasn’t quite sure what to expect. I still feel like there’s so much I still need to learn, but I’m definitely getting into the red team mindset and these rooms are getting easier. The description mentioned…

This writeup is for the TryHackMe room “Brainpan 1” at https://tryhackme.com/room/brainpan. The goal for this room is to reverse engineer a WIndows executable and craft a buffer overflow to gain access to the machine. There are three questions for this room with no flags to capture, so I’ll have to measure my progress by access level:…

This is my writeup for the TryHackMe “Gatekeeper” room at https://tryhackme.com/room/gatekeeper. Gatekeeper is a delightfully vague room requiring me only to submit a User flag and a Root flag. There is little description beyond mentioning a gate and fire twice. Sounds exciting! Let’s begin. Note: since TryHackMe does not accept writeups for this room, I will…

Source room: https://tryhackme.com/room/bof1 This task is just like the Task 8 machine, except with different offsets. Let’s dive right in! I SSHed into the machine and into the overflow-4 folder. There is another secret.txt file, this time only accessible only by user3. Looking at the source code, there’s no input validation so this is a good candidate…

This is my writeup for the TryHackMe Brainstorm room. The goals of this room are to reverse engineer a chat program running on a Windows machine and write an exploit to gain root access. It’s recommended to complete the previous buffer overflow exercises. I just finished the Buffer Overflow room so I felt reasonably prepared to attempt this…
