Hackers have targeted Japan's electronics giant Sony, claiming that they have stolen personal information of more than one million user accounts.
A group calling itself "Lulz Security" announced a new round of cyber attack on Thursday, posting online snippets of data it says came from a breach earlier this week of personal information belonging to one million user customers, The Huffington Post reported.
The group claims the information includes unencrypted passwords, names, addresses as well as birthdates for thousands of people.
The group also claimed that the hack "compromised all admin details of Sony Pictures (including passwords) along with 75,000 'music codes' and 3.5 million 'music coupons.'"
In April, hackers managed to steal data of about more than 77 million Sony PlayStation network users in a cyber attack, which forced the electronics giant to shut down its PlayStation Network and other services for nearly a month.
"This type of attacks exposes [one] of the fundamental flaws that most companies take to risk management. Focusing on securing your primary site (such as a purchasing site) leaves secondary sites exposed, and they often contain valuable customer data," Jeremiah Grossman, CTO of WhiteHat Security, said.
On Thursday, the executives of the Japanese electronics giant came under heavy fire from US lawmakers over why Sony consumers were not informed more quickly about the cyber attack.
Over 100 million user accounts were affected and the company only recently was able to restore service, the report said.
