Hi all,

I've put some more stuff online I created in the last two years; ASCII Art shellcode: http://skypher.com/wiki/index.php?title=ASCII_Art/Shellcode/Organic *http://skypher.com/wiki/index.php?title=ASCII_Art/Shellcode/Blocky*<http://skypher.com/wiki/index.php?title=ASCII_Art/Shellcode/Blocky> http://skypher.com/wiki/index.php?title=ASCII_Art/Shellcode/Julia

As the name suggests, it is working shellcode that's also ASCII Art. They all use the same basic principle: a small decoder embeded into the first characters of the ASCII Art. After the decoder, the original shellcode is encoded into the remainder of the ASCII Art. When executed, the decoder decodes the original shellcode and runs it, similar to how my ALPHA2 alphanumeric shellcode works.

If you are going to release an exploit, you might as well make it look good.
