[Tuto] Learn hexadecimal crypt [FUD] - Zerotime - Aug 25, 2014
It's very good tuto to make FUD a server !
Hexadecimal crypt it's change the bit value detected by anti-spyware of your server to make undetectable.
If you have motivation, you can make FUD your servers for free in 2hours !
Make like on video because it's a very good tutorial 🤝
Use VM to crypt.
If you want help for hexadecimal notions, contact me.
P.S : sorry for wrong section...

That's a really nice video you shared with us, I like it.
I will sure try this method in an educational purpose, to see if I can get ride off BitDefender in a VM.
I have a few questions ... Why do you choose to fill with the hex value 1c and not another ?
What about an offset that is more than 1 column sized, how did it affects the functionalities of the exe file ?
Sorry about dumb questions, i'm pretty new to all of this, very curious.
Thanks to you :)

Thanks for you comment :)
You can't remplace value with anyone in hex, the value remplaced need semblabe of first.
No problem to work because it's just a bit and servers have millions Kbits 🤝

Thanks for the reply, I guess I just should try it now :)
For example, if I have a crypted file with a 5/35 detection ratio, could I UD'd it for a certain AV (nod32 for example) then take the new test2.exe and do the same operation for any other AV and make it FUD or 1/35 ?
I guess it takes time but eh, it's amusing.
Do you have any link for the softs you are using in the video ? (Signature tool and Hex editor ?) I checked on the website in description, but didn't find any :/)
