Two hackers, Mondo Armando and Mustaschio, are claiming April 2007 as the Month of MySpace Bugs.  On their blog, they are claiming that MySpace is full of security vulnerabilities and will reveal each bug one at a time.  Saying that they could easily hit sites such as Google and Yahoo, MySpace would be more fun:

“The purpose of the exercise is not so much to expose Myspace as a hive of spam and villainy (since everyone knows that already), but to highlight the monoculture-style danger of extremely popular websites populated by users of various levels of sophistication. We could have just as easily gone after Google or Yahoo or MSN or ZDNet or whatever. Myspace is just more fun, and is becoming notoriously dickish about responding to security issues.”

Actually, the reasons for going after MySpace are more: the News Corp-owned domain is the biggest social site in the world, thus bringing a lot of profits to its owners. There have also been many scandals in the past concerning MySpace’s security against phishing attacks and against sexual predators.
