From: psyphreak at phreaker.net (Peter Willis) Subject: Re: New whitepaper: Writing IA32 Restricted Instruction Set Shellcode Decoder Loops Hey, cool paper. Speaking of phrack, if in the future you have an article you think is print-worthy but is rejected by most zines, try sending it to Binary Revolution <articles@...rev.com>. Although they're newer and have had some delays in getting new issues out, they're starting to re-focus on the magazine and the number of their supporters is growing. Sorry if this comes off a little advertisey, but hopefully if more people write in then BinRev can publish more original articles about vulnerabilities which can then make it back onto the web as sample articles.

Most of it is based on my experience with alphanumeric decoders but the principles apply to any piece of code that is written to work with a limited instruction set.
