FUD CRYPTER : by pass anti virus detection

I have already written about RATs in my previous article PRORAT - Remote pc access software. I have mentioned about antiviruses detecting RATs as hacking softwares (viruses) and hence, hacker has to use Crypters to avoid antivirus detection for RATs. So, read on to know more on Crypters - hacking software for bypassing antivirus detections. I have provided link for software download.

What is Crypter??

As said above, Crypter is free software used to hide our viruses, RATs or any keylogger 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. so i am going to give you a fud crypter witch is rare to get so please thank me in comments
