Regardless of Microsoft's assurances that the whole NSA backdoor scandal from last week (story) was just a lot of unsubstantiated hype, a real and potentially serious backdoor has been discovered in Beta 3 of Windows 2000. According to ZDNet, there is "a simple technique that would give an attacker full access to a susceptible machine" and is due to the "autologin" feature of Beta 3. Microsoft plans to address this in Release Candidate 2, which is expected soon.
