Wired News: Quickest Patch Ever:
Microsoft is in the business of making money, and keeping users secure by patching its software is only incidental to that goal.
There's no better example of this of this principle in action than Microsoft's behavior around the vulnerability in its digital rights management software PlaysForSure.
Last week, a hacker developed an application called FairUse4WM that strips the copy protection from Windows Media DRM 10 and 11 files.
Now, this isn't a "vulnerability" in the normal sense of the word: digital rights management is not a feature that users want. Being able to remove copy protection is a good thing for some users, and completely irrelevant for everyone else. No user is ever going to say: "Oh no. I can now play the music I bought for my PC on my Mac. I must install a patch so I can't do that anymore."
But to Microsoft, this vulnerability is a big deal. It affects the company's relationship with major record labels. It affects the company's product offerings. It affects the company's bottom line. Fixing this "vulnerability" is in the company's best interest; never mind the customer.
So Microsoft wasted no time; it issued a patch three days after learning about the hack. There's no month-long wait for copyright holders who rely on Microsoft's DRM.
This clearly demonstrates that economics is a much more powerful motivator than security.
