Microsoft WMP 10 and 11's DRM got cracked this week and now Apple's iTunes 6 DRM got cracked too.
QTFairUse6 looks at AAC frames in memory after they've been decrypted, but before the decoding step, and dumps the data into a file. It currently only runs under Windows, and relies on iTunes for the actual decryption work as well as FAAD for making the dumped data into playable AAC files. Unlike earlier tools like Hymn/JHymn and the original QTFairUse, this program can handle streams from iTunes 6.0.4 and later.
