Hello boys and girls of America and beyond, and welcome to my latest
|
|||
|
|
endeavor into the performing art of coding. This software simply
|
|||
|
|
cracks encryption using any of the following techniques:
|
|||
|
|
|
|||
|
|
8-bit ADD and SUB 16-bit ADD
|
|||
|
|
8-bit XOR 16-bit XOR
|
|||
|
|
8-bit ROR and ROL 16-bit ROR and ROL
|
|||
|
|
8-bit NOT 16-bit NOT
|
|||
|
|
|
|||
|
|
Which means you can now easily decrypt the majority of computer viruses
|
|||
|
|
out there and see what text is inside without having to ever touch a
|
|||
|
|
disassemble. Not to mention the fact that there are LOTS of software
|
|||
|
|
which uses these encryption algorithms for its internal or external
|
|||
|
|
encryption purposes.
|
|||
|
|
|
|||
|
|
|
|||
|
|
How to Use:
|
|||
|
|
************************************************************
|
|||
|
|
The command line syntax is:
|
|||
|
|
VIROCRK [filename] [text]
|
|||
|
|
|
|||
|
|
[filename] is the file you're wishing to crack. It should not exceed
|
|||
|
|
62k
|
|||
|
|
[text] is a few bytes which you think will be contained in a decrypted
|
|||
|
|
copy of the file. This parameter is case sensitive. The more
|
|||
|
|
plaintext you can come up with, the fewer false positives will
|
|||
|
|
arise.
|
|||
|
|
|
|||
|
|
Examples:
|
|||
|
|
VIROCRK HELLO.COM COM
|
|||
|
|
VIROCRK ALPHA.TXT THE
|
|||
|
|
VIROCRK IVB.NTZ COM
|
|||
|
|
VIROCRK HELPME.EXE LA LA PA LOO ZA
|
|||
|
|
|
|||
|
|
While VIROCRK is running, hit a key to abort. The exit may not be
|
|||
|
|
immediate.
|
|||
|
|
|
|||
|
|
|
|||
|
|
Output From VIROCRK
|
|||
|
|
************************************************************
|
|||
|
|
When a successful decryption occurs, VIROCRK writes the decrypted
|
|||
|
|
file to a DEC-XXXX.??? filename. The last 4 bytes of this filename,
|
|||
|
|
and the extension indicate key and decryption technique used.
|
|||
|
|
|
|||
|
|
DEC-XXXX.??? :
|
|||
|
|
|
|||
|
|
XXXX- Key between 0 and FFFF. This is, ofcourse, hexadecimal.
|
|||
|
|
|
|||
|
|
???- 8XR = 8-bit XOR
|
|||
|
|
8SB = 8-bit SUB
|
|||
|
|
8RT = 8-bit ROR
|
|||
|
|
16X = 16-bit XOR
|
|||
|
|
16S = 16-bit SUB
|
|||
|
|
16R = 16-bit ROR
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||

|
History
|
|||
|
|
************************************************************
|
|||
|
|
v1.0 - Initial Release
|
|||
|
|
v1.1 - I changed something
|
|||
|
|
v2.0 - <20> Improved speed significantly by now attempting to encrypt
|
|||
|
|
the plaintext with each possible key rather than decrypt
|
|||
|
|
the ciphertext with key. Note that since I switched to this
|
|||
|
|
faster method, the plaintext sequence should be greater than
|
|||
|
|
three bytes or you'll have many false positives after adjusting
|
|||
|
|
the 16-bit addressing.
|
|||
|
|
<20> No longer attempts address-adjusted 16-bit XOR; no point in this.
|
|||
|
|
The byte-reversed key should have been successful in the
|
|||
|
|
non-adjusted 16-bit XOR.
