Security specialist Sophos has put out a stark warning to anyone who has entered their credit card details on the PlayStation network, saying they should "cancel that card immediately".
Sony this week admitted that a hacker has infiltrated the PSN and, along with it, the personal information of potentially all of the 70 million people who use the service.
In the UK, three million people are part of the PSN, and Graham Cluely from Sophos believes that everybody should be changing passwords and cancelling cards to minimise any damage.
Treasure trove
"If you're a user of Sony's PlayStation Network, now isn't the time to sit back on your sofa and do nothing," said Cluely.
"The fraudsters won't wait around - for them this is a treasure trove ripe for exploiting. You need to act now to minimise the chances that your identity and bank account become casualties following this hack."
"That means, changing your online passwords (especially if you use the same password on other sites), and considering whether it would be prudent to inform your bank that as far as you're concerned your credit card is now compromised."
Alongside credit cards and passwords, there were also personal details obtained – such as dates of birth, email account information, names and addresses.
Sony does not yet know how systemic the hack was, but announcing that all credit card details could be compromised means that this could be one of the biggest data leaks the web has ever seen.

if your smart you'll leave you credit on > if anything happens to your money > sue sony = profit :carling:

That is probaly the best u can do but It will cost us between7-15euros for a new card
