Sony had again had their security broken where this time is only around 93,000 accounts were affected. 3 sections of Sony were involved which are the Sony Entertainment Network, PlayStation Network (PSN) and Sony Online Entertainment services according to Sony blog.
Philip Reitinger, the Chief Information Security Group of Sony Group who were hired 5 weeks ago decided to locked all the 93,000 accounts that are affected for security purposes. Those affected users will be emailed and asked to proof their identity later before their account can be activated back.
Sony who had already been breached terribly about 6 months ago is now like a ship with a hole in the middle sinking down slowly where Philip Reitinger is the newly hired guy to fix the hole and stabilize the entire ship. So far, the issue had been handled professionally.
How Sony discovered the break in?
According to Philip Reitinger, there was particularly high rate of unauthorized attempts for login which forced them to lock all the affected accounts. It is suspected that it could be some automated script where the cyber crooks might got the username from the previous data breach that happen to be shared somewhere on the internet.
Since the previous breach, I believe Sony had taken some action to enhance their IT security infrastructure. As a result, suspicious activity such as the current one is reported and immediate action is taken to stop further damage.
What should you do if you are affected?
Basically on the Sony part, they had taken all the countermeasure to stop the attack from going any worse. However, if you happened to be the unlucky one, remember to change your password if you happen to use the same password for your Sony account and other online accounts.
This is to prevent the attacker who successfully compromised your current account to use it on your other accounts. Of course if you are having some difficulty in creating a password, do always refer to my guide on how to create a strong password.
