Here it comes. The first lawsuit since Sony admitted that there'd been a security breach over the PSN has been filed on behalf of Kristopher Johns (38), a resident of Birmingham, Alabama, in the U.S. District Court for the Northern District of California.

CNET reports that Johns is accusing Sony of not taking 'reasonable care to protect, encrypt, and secure the private and sensitive data of its users'. Furthermore, the complaint also encompasses accusations that Sony took far too long to notify customers of the breach and warn that personal information was at risk, alleging that Sony did not therefore allow customers 'to make an informed decision as to whether to change credit card numbers, close the exposed accounts, check their credit reports, or take other mitigating actions.'

Johns is requesting financial compensation and is also looking to upgrade the lawsuit to class-action status, a move that would allow any US PlayStation Network user to become a plaintiff in the case as well, if such status is granted.

The complaints echo those of Sen. Richard Blumenthal yesterday, in particular the request from Johns for free credit reporting services.

The 'reasonable care' part will no doubt be uncovered by an independent investigation, there is still no evidence suggesting fraud or misuse as yet, though the storing of some details as unencrypted text may well prove a sticking point. The communication issue, however, has been widely perceived as inexcusable, a view that will only be reinforced should any misuse come to light.
