Today I listened to a podcast from Defcon by Dan Kaminsky on how ISPs are shutting down individuals due to usage levels, SSL problems and how he was able to hack DNS. All interesting stuff, but the cream was in his description of pattern recognition in hex data.

This was really cool. He talked about a tool that takes chucks of file data (programs, MP3's, etc.) and looks for matching patterns and then displays it visually. He talked about how our brains can't remember unstructured stuff (strings of data and unrelated words), but can remember names and patterns.
His use for this was to look for patterns in programs that he can fuzz or look for changes in versions of a program. Very cool.
I need to think about how this might be used to recognize patterns in statistical data in my job.
Amazing how stuff from left field seems to apply to what I do on a daily basis...
