Nameless C2 - A C2 with all its components written in Rust.

Nameless C2 is a small project I started for fun to get a bit familiar with Rust but I do not have any time to continue working on it,
hence I am publishing it in hope that some might find it useful to build on top of it since it needs a LOT of work.

Another damn C2? WHY?!

That is totally fair to think that and I agree, I am mostly publishing it due to the fact that I have not seen another Windows Rust implant as small as 256kb (if my memory serves me right) and also has a working sleeping obfuscation method of EkkoEx. Is this the best C2 or super OPSEC? Definitely not! Is it worth playing around with it? I will leave that up to you.

Installation Process

I highly recommend that you build the terminal and the implant in Windows boxes while the server should be built ideally on debian.

1. Dependencies on debian for the NamelessServer:

• sudo apt install libssl-dev libsqlite3-dev.
• goes without saying... install rust

2. Compile terminal and agent ideally with the below command.

• cargo build --release --target x86_64-pc-windows-gnu.

Notes

There are some stuff left around to take a look and discover, I am not gonna go into how to build things, don't bother opening issues, I am not gonna fix them.

• The terminal application works better in Windows than Linux.
• The implant generates a DLL with an export called DiagnosisCheck, to generate shellcode I have provided a modified sRDI which you can simply use by running
  python3 ConvertToShellcode.py -c -f DiagnosisCheck NamelessImplant.dll
• Make sure you check in the implant the kill date, change the hardcoded IPs/Domains.
• Coming form PoshC2, this C2 has a similar way of obtaining the output. When the server will start,
  it will generate a NamelessLog.txt which you can tail command to obtain and keep up with everything
  tail -f NamelessLog.txt
• For the Rust gurus, you will notice stupid choices in the code that make absolutely no sense and I agree but I suck at Rust ¯_(ツ)_/¯
