The mega Sony PlayStation breach in April kicked off a slew of attacks for the electronics giant well into May. Sony took down its PlayStation Network login and password reset pages to block a serious security vulnerability following reports of yet another external hack targeting user accounts. The vulnerability occurred in the way that the password reset form is implemented, which contained a glitch that failed to properly verify tokens. The flaw enabled hackers to launch attacks only by knowing users' date of birth and e-mail addresses in order to access their PlayStation Network accounts.

Researchers at U.K.-based gaming news blog yleveia.com reported that they "provided a detailed description" of the exploit to Sony as soon as it was detected, after which Sony immediately took down the login and password reset sites. The hack followed just a few weeks after Sony suffered a massive cyber attack targeting its PlayStation Network and Qriocity services that compromised more than 77 million accounts.
