| Microsoft Passport DOS (denial-of-service) attack For those not familiar with Passport, it is basically an attempt by Microsoft to increase it's ability to rule the world :-) They want everyone to store their login credentials there, then have all e-commerce, banks, and other sites transparently make authentication calls to the centralized Passport database to validate your identity (instead of the site itself maintaining your password and validating against it). MS also wants everyone to store their credit card information, and other vital personal details with them: MS wants all of our eggs put into their one basket.
Yesterday I tried to post at a web site where my credentials were stored in MS Passport and couldn’t. Why? An error message appeared stating that too many failed attempts had been made to login with the wrong password for my e-mail account, so my account was being temporarily locked. From a security standpoint, that’s the thing to do…you don’t want people being able to submit password after password against your account until they succeed. The problem is that while the locking of the account did prevent the attacker from logging in, it also prevented me from being able to log in. So I couldn’t post at that site yesterday. When someone does something malicious and thereby prevents you from able to access resources you should be able to, that’s a denial of service attack. And with Passport it is apparently quite simple to launch: just get a legitimate e-mail address (what Passport accounts are based on) and the submit some passwords. You don’t have to worry about guessing the correct password, just the act of you guessing locks the person out of their account.
Now, after a dozen attempts at various times in the morning yesterday, I finally give up. This morning, after at least 17 hours of no login attempts, I tried again. Still locked out. Wow, what a long TEMPORARY locking of my account. So far that makes a 2-day DOS. And I have no idea how long this will continue.
Big deal, you might say, I couldn’t post at one site. But, what if MS had their way and all of my personal information was stored on their servers, and e-commerce, banks, and other sites required Passport authentication? Then for 2 days - so far - I would have been unable to do anything on line…no banking, no shopping, no paying of bills, no posting at sites…nothing.
Worse, this is the SECOND time in about 4 months that my account has been temporarily locked because someone has made of too many wrong passwords attempts against my account. |
