How to Make Your Own FUD Crypter

Tweet

What is Crypter?

As said above, Crypter is free software used to hide our viruses, keyloggers or any RAT tool from antiviruses so that they are not detected and deleted by antiviruses. Thus, a crypter is a program that allow users to crypt the source code of their program. Generally, antivirus work by splitting source code of application and then search for certain string within source code. If antivirus detects any certain malicious strings, it either stops scan or deletes the file as virus from system.

What does Crypter do?

Crypter simply assigns hidden values to each individual code within source code. Thus, the source code becomes hidden. Hence, our sent crypted trojan and virus bypass antivirus detection and our purpose of hacking them is fulfilled without any AV hindrance. Not only does this crypter hide source code, it will unpack the encryption once the program is executed.

What is FUD?

FUD is acronym for Fully UnDetectable. With increased use of Crypters to bypass antiviruses, AV became more advanced and started including crypter definitions to even detect crypter strings within code. So, use of crypter to hide Ardamax keylogger and RATs became more complicated as nowadays, no publicly available crypter is FUD.

So, if you crypt RATs with publicly available crypters, they are bound to be detected by antiviruses. This is because most FUD crypters remain "FUD" for maximum of one or two days after their public release. To obtain FUD crypters, you have to either search for it in hacking forums or make one (which is somewhat tedius.. I am working on this).


Now you can make your own crypter by following on this tutorial.
