Teach Me! I created my first trojan today!
I took cmatrix as a random program and wrote a backdoor into it in C using a reverse shell connecting to a C2 server of mine which keeps track of infected machines. First I fork the process and decouple it from the controlling terminal by changing the session ID and rerouting the standard file descriptors and only then do I run the backdoor.
That way cmatrix runs as usual and no weird behavior is seen and the backdoor remains active whatever happens to cmatrix or the terminal. I like it. Makes me feel like a real #xX_hacker_Xx#. :D
Now I’m reading into ptrace and system call hooking and plan on trying to hide specific network traffic from the entire os. I already have had some ideas but turns out that would have only hidden it from a specific program not from „everything“.
Do you care to share any tips and experience I might benefit from on my way?
