The company's networks

Sony's security woes are continuing unabated as two more hacking groups today claim to have broken into the company's networks.

According to information posted Tuesday on Pastebin.com, hackers have to all appearances broken into a database at Sony Ericsson's Eshop online store for mobile phones in Canada and extracted the names, usernames and passwords of thousands of users.

Sony sites have been hacked several times in several weeks, which analysts say shows that the company's online networks are very porous.

The biggest of these attacks

The biggest of these attacks by a long way happened in mid-April, when attackers broke into Sony's PlayStation Network and Sony Online Entertainment and compromised personal data of some 70 million account holders and another 12 million or so credit and debit card holders.

Those attacks caused Sony to take down PSN and SOE for several days during it worked with three external security firms to find and fix the security holes. About 10 days ago, Sony announced that it had fixed all problems with its PSN and SOE networks and partially restored those services.
