What Is FUD Crypter?
FUD is acronym for fully undetectable.It is a software that can be used to encrypt your exe files.
What is the use of FUD Crypter?
FUD crypters can be used to encrypt viruses,RAT,keyloggers,spywares etc to make them undetectable from antiviruses.You can also read my post on spywares,viruses and worms or How to fool Keyloggers.When these exe files are encrypted with Fud crypters they become undetectable with antiviruses
How Does FUD Crypter Work?
The Basic Working Of FUD Crypter is explained below
The Crypter takes the original binary file of you exe and applies many encryption on it and stores on the end of file(EOF).So a new crypted executable file is created.
Original Exe Crypted Exe
001————- 010                                      101————-110
100|Original File|000->  Cryptor  ->010|Original File|110
010————- 111                                        110————-010
The new exe is not detected by antiviruses because its code is scrambled by the crypter.When executed the new .exe file decrypts the binary file into small the data small pieces at a time and injects them into another already existing process or a new empty one, OR it drops the code into multiple chunks in alternative data streams(not scanned by most a/v) then executes it as a .txt or .mp3 file.
Why Most FUD Crypters Donot Work?
As a FUD crypter becomes popular it also get the eyes of antivirus companies.The antivirus companies update their software and employ detection mechanism that detect the encryption’s by the crypter.So, most of the popular FUD crypter are easily detected by antiviruses.
Note:-Donot test your crypter on virustotal.com as it distributes the samples and your crypter will not remain FUD if you scan with virustotal.
Where can I Download a Free FUD crypter?
As I already mentioned that as the crypter becomes popular it doesnot remain FUD.So the only FUD crypter available are those made by indivuals and they can be found by spending a little time on google by searching.It will not make profit to anybody if I share my FUD crypter here as it will not remain FUD for long as some noobs will surely scan it with virustoal.So,its better you search your own and keep it to yourself.
Note: .netframework should  be installed in your system before running the crypter.
