What is FUD Crypter and how to use it to Bypass antivirus detection for RATs and viruses
I have already written about Keyloggers in my previous articles, like Azure AIO Keylogger, Star Tools, Ref Stealer and many other keyloggers previously to hack e-mail account passwords. I have mentioned about antiviruses detecting keyloggers as hacking softwares (viruses) and hence, hacker has to use Crypters to avoid antivirus detection for keyloggers. Here i'll tell you something more about Crypters - hacking software for bypassing antivirus detections.
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).
Download FUD Crypter for Free
1. Free Download Blackout Crypter with Stub Package to make virus undetectable and hack email passwords.
2. Run Blackout Crypter.exe application to see this:
3. Now, select AES or RC4 as your needs. I have selected AES over here. Hit on "Select a stub" and browse to Stub Package folder. Select AES or RC4 stub you want. Here, I have used "Stub 9" from AES folder. The difference between AES and RC4 Encryption System is that AES is the most secure and RC4 is fastest!
4. Hit on "Select a file" and select the server file you want to make undetectable from antiviruses. You can use Ref Keylogger, tDevil, Azure AIO Keylogger or Star Tools Keylogger to create a server.exe file. Now, hit on Crypt it and you will get "Crypted.exe" file created in current directory (in "Blackout Crypter" folder).
5. Features of Blackout Crypter:
- 100% FUD - No AntiVirus will detect your file!
- 100% FREE
- AES and RC4 Encryption System
- 256-Bit Password - Amazingly secure your file
- Destroy Antivirus - When ran, all antiviruses will be KILLED and DELETED, and then your virus will be ran. All this is done SILENTLY.
- Scantime and Runtime (After AntiVirus kill) FUD (AntiVirus will be destroyed before running your encrypted file)
- Supports every damn .exe file on the net!
- EOF Support - Works with Cybergate.
As the virus scan result shows, Kbw-Logger was 10/21 detectable to antiviruses. But, after crypting it with Blackout Crypter, this detection rate dropped to 1/21.

7. This crypter package contains 12 stubs. So, even if one stub becomes detectable, try out another one. I have personally tried this one and found useful to hack Hotmail password. If you have any problem in using this FUD Crypter to make server undetectable to antivirus, please mention it in comments.
Very Important: Do not scan these tools on VirusTotal. Use http://scanner.novirusthanks.org and also check the "Do not distribute the sample" option.
So guys, this is all about crypter. Hope you found this post useful.
