DynWin32-ReverseShell.ps1 is a reverse shell based on dynamically looked up Win32 API calls.
The script uses reflection to obtain access to GetModuleHandle, GetProcAddress and CreateProcess.
Afterwards it uses GetModuleHandle and GetProcAddress to resolve the required WSA functions
from ws2_32.dll.

This script should be used for educational purposes only (and maybe while playing CTF :D).
It was only tested on Windows 10 (x64) and is probably not stable or portable. It's only
purpose is to demonstrate the usage of reflective lookups of Win32 API calls. See it as

A TL;DR solution to Security Driven by @terjanq

For this year's Google CTF, I prepared a challenge that is based on a real-world vulnerability. The challenge wasn't solved by any team during the competition so here is the proof that the challenge was in fact solvable! :)

• Link to the challenge: https://capturetheflag.withgoogle.com/challenges/web-security-driven
• Link to the PoC: https://github.com/google/google-ctf/tree/master/2021/quals/web-security-driven/solution

The goal of the challenge was to send a malicious file to the admin and leak their file with a flag. The ID of the file was embedded into the challenge description (/file?id=133711377731) and only admin had access to it, because the file was private.

Disclamer: The write-up is written on airplane therefore the quality of it is poor, mostly to showcase the required steps to solve the challenge
