Analyzing unknown binary files using information entropy
- snarfy 11y agoI always thought this idea could be greatly expanded upon. I've seen it used to guess the native language of a text file based on the compressed input. I always believed this could be used as a sort of universal translator. You could compress the audio sounds of birds, throw this algorithm at it, and extract meaningful content.
- woliveirajr 11y agoTo tell the truth, it already has been proposed and there are some papers about it. Search for "NCD - Normalized compression distance" and you'll get some results. It's even used to verify who is the author of some document (authorship attribution). Very interesting.
- woliveirajr 11y agoThere is some technique called "normalized compression distance" that does sort of it. It uses compression to compare how similar some data is to some another. For a similar problem, you can work like it was answered here: http://reverseengineering.stackexchange.com/questions/2897/tool-or-data-for-analysis-of-binary-code-to-detect-cpu-architecture/2900#2900 http://reverseengineering.stackexchange.com/questions/2897/t...
