    Oh, heads up this uses a reverse text padding infection to host the new dynamic strying table. Reverse text padding infections don’t work on position independent executables. So the infection technique should be switched over to something else like a PT note to PT load conversion

    Wrote a shared library injector (i.e. DT_NEEDED infect) that comes with a simple keylogger. Keyloggers are awesome.
