JAPANESE ENTERTAINMENT FIRM Sony is contacting some users across the globe and recommending they change their passwords.
There has been a recent spate of email alerts about password changes, and Sony is one of the latest to react to what could be a far reaching attack.
It apparently has been reaching out to customers with an email campaign. At The Verge two staffers have been sent the email and a statement from Sony about what it means for users.
The email sent to customers suggests that they choose a strong password and use it. The message mentions "irregular activity", but doesn't go much deeper than that.
"The Sony Entertainment Network team routinely monitors for any irregular activity, and if such activity is detected, we may sometimes reset passwords of affected accounts to protect consumers and their account information.
"Your account password was recently reset as part of this process and you will need to create a new password the next time you access your account using the 'Forgot Your Password' option on the Sign in screen," said the email.
"We encourage you to create a complex unique password that you have not used before or isn't the same password as those associated with other online services. As always, we also encourage you to keep a close eye on your account for any unusual activity including emails about transactions you did not perform."
Sony was burnt by one of the biggest security assaults ever made on a company and was knocked offline for some months in 2011. Sony was fined £250,000 in the UK for the attack its gaming network that compromised millions of gamers' personal information.
Then Sony seemed to accept that it and other large organisations are always going to be targets for hackers.
"Criminal attacks on electronic networks are a real and growing aspect of 21st century life and Sony continually works to strengthen our systems, building in multiple layers of defence and working to make our networks safe, secure and resilient," it said.
This week firms including Facebook, Google, Yahoo, Twitter have all been compelled to alert users to possibly compromised accounts. µ
