hacking: security in practice
Have any of you guys made/tried making sneaker/gpu/console bots?

I'm in the middle of making my second PS5/Xbox (console) bot and I've found the process pretty interesting. My first bot I just used a headless browser and spammed actions on the site which wasn't very useful when there was high traffic. The second one I'm working on right now is 100x better and doesn't use those slow methods at all. I come from app and web development so this really isn't domain but it seems like so much fun!



Always knew it was the pen test/hacker guys making bots. Just curious to see if it's a common thing to dabble with coming from this field

Lsass NTLM Authentication (https://www.kitploit.com/search/label/Authentication) Backdoor
How it Works
First, the DLL is injected into the lsass.exe process, and will begin hooking authentication WinAPI calls. The targeted function is MsvpPasswordValidate(), located in NtlmShared.dll. In the pursuit of not being detected, the hooked function will call the original function and allow for the normal flow of authentication. Only after seeing that authentication has failed will the hook swap out the actual NTLM hash with the backdoor (https://www.kitploit.com/search/label/Backdoor) hash for comparison.
Usage
Nosferatu must be compiled as a 64 bit DLL. It must be injected using the a DLL Injector (https://www.kitploit.com/search/label/DLL%20Injector) with SeDebugPrivilege.
You can see it loaded using Procexp:
 Login example using Impacket:
Limitations
In an Active Directory (https://www.kitploit.com/search/label/Active%20Directory) environment, authentication via RDP, runas, or the lock screen does not work with the nosferatu password. Authentication using SMB, WinRM, and WMI is still possible.In a non-AD environment, authentication works for all aspects.
