I'm trying to develop an alphanumeric payload that needs to do a JMP -600
bytes... ALPHA2 encodes shellcode to alphanumeric, unicode alphanumeric, uppercase alphanumeric and uppercase unicode alphanumeric. http://www.edup.tudelft.nl/~bjwever/documentation_alpha2.html.php You can download the source and compile it or use the online version.
Beyond that, I'd be extremely surprised if someone hasn't written tutorials on doing alphanumeric-only payloads,
Writing ia32 alphanumeric shellcodes by rix: http://www.phrack.org/show.php?p=57&a=15 Building IA32 'Unicode-Proof' Shellcodes by obscou: http://www.phrack.org/show.php?p=61&a=11 Writing IA32 Restricted Instruction Set Shellcode Decoder Loops by SkyLined http://www.edup.tudelft.nl/~bjwever/whitepaper_shellcode.html.php
if not even provided toolkits to take arbitrary code and "ASCII-fy" it.
See ALPHA2.
Would dissembler do what you want? It should be able to squeeze the ascii shellcode for you ;-)
Nice tool ;) But printable characters are not all alphanumeric characters. Cheers, SkyLined -- Berend-Jan Wever <berendjanwever () gmail com> http://www.edup.tudelft.nl/~bjwever
