The fact that it happened in a "for free" situation means that the exploit was pretty good. It's a bit difficult to find an explanation of how to find collisions for MD5 and SHA1, but the general idea of a hash collision is very straightforward. The concept behind a hash collision attack is to take two different strings, and generate a file that somehow makes them into the same file. Since a file's hash value has to be unique, a good hash collision attack will make two files have the same hash. This is tricky because of the way in which hash values are built. Hashes are built by taking the hash value of some string, and XORing the hash value with itself. (XOR stands for Exclusive Or, a logical operation that works like an AND or OR but with only one bit set). This means that the hash value of two different strings will usually have the same values for their first half. There are a few methods to generate hash collisions, but the most common are iterative, which proceed as follows: Take two different random strings, let's call them x and y Take the hash of each string, sha1(x) and sha1(y) XOR the hashes together Check if the result is sha1(x) If so, repeat steps 2-3 with new x and y This method can be modified slightly to work with MD5 (just use the MD5() function instead of sha1()): Take a random string (you can use e.g. rand(0, 8).to_s() in ruby and hex(rand(0, 8) ^ rand(0, 8)) for C++ or any other random-looking string) Take the MD5 hash of the string XOR the hash together Check if the result is sha1(x) If so, repeat steps 2-3 with new x and y Both of these methods can be easily modified to work with any other type of hash by replacing sha1() and hashing(). Of course, making a hash collision is not very useful in and of itself - if you want to reverse engineer software and get access to sensitive data, a better method is an actual keylogger. Q: Is the issue you're having related to the new system (Windows 8)? You can get help and ask questions about Windows 8 here: The beta sites are all available in English only. If you're trying to get help with a store-bought app, you might try The forums also have a lot of help topics. You can follow progress in the Windows 8 software development blog. and the Windows SDK team's Q&A site. And in case you have any troubles with the *nix based software you use, it's possible they're on the Ask Different site, too. If you get stuck with an app, try a reinstall. If that doesn't work, uninstall and reinstall. That works for free apps, and if the app isn't in the store, you can try the Windows Store, though you'll probably be out of luck. You can report a problem directly to the Windows Store team. You can submit questions on the Windows 8 Apps forum. It may help to take a photo and post it on a web site like Or maybe you'll make a video. Hopefully, something that works with Windows 8 will work for Windows 7, too. Good luck. --Wil d0c515b9f4
