Hi

is there any possibility to make a bootable USB stick like Rufus and get it to autostart a RAT BEFORE the windows and its security tools are started?

alternative way: is it possible to replace with this bootstick a file like osk.exe in the windows directory so i can start the osk (on screen keyboard) and my rat will be executed ?

No there is no option how to run RAT before OS boots. Why ? Because RAT is depends on OS.

He's correct.

You need an OS to run a RAT. Why would you even need to run a RAT before the OS boots?
I sometimes come around and poke a few threads before leaving for a few months again.

Perhaps because his RAT's stub isn't fud so he simply wants to avoid the AV's. Imagine if you could run any RAT on any computer before the OS boots lol. Chaotic.

I know what you guys are saying, but i want to replace a useless EXE in the sysfiles like OSK.EXE

then i hit run type in OSK.EXE and my replaced exe (rat) will be executed

why do this? because of the security settings

Yes it is possible to start a RAT before any other programs loads and before AV. But not before windows (not with a basic rat i mean).

And yes you can replace any files in the rufus install. But it will not be protected from any good security good program. And Windows File Protection / Windows Ressource Protection will throw you a bsod at startup if you touch any protected files.

You can inject your RAT into that process (RunPE) but you will need to have administrator rights to do it. And also... Why you do not want to use startup function in crypter, change assembly information and put that file into sysfiles ?

Unfortunately thats not possible. Well everything is possible but its not easy. You could if you want it to run before anything and for it to be ignored. If you could replace the explorer.exe with your rat embedded into it. That way your antivirus would run it as soon as windows loads. There could be issues with this tho such as it not functioning on systems depending on operating system model and version. Thats the easiest way i can think of for it to be 100% and irremovable. You could just maybe embed code into your rat presume you were coding it that would disable that antivirus and add an exception, you could do this in many ways including creating a script that would run a hidden vnc and create the exclusion then delete it.
