Microsoft defeated by crackers (again) Vista activation got cracked.

Since last week, rumors have surfaced about Vista's activation crack. Not until this weekend that the story was verified, its true. Vista got cracked and MS scrambled to release KB929391 WGA to patch the hole but warnings has already excalated not to apply the patch for cracked Vista.

The crack is ingenious, tit actually runs an emulated WGA authentication server and validates the Vista installation. This technique is not entirely new, using packet reverse engineering any server can actually be emulated, even Blizzard's complex WOW server has been emulated a few weeks after the game was released out of beta. Certainly MS WGA server isn't as complex as WOW server so it not surprising it was reversed that fast.
