Hackers Take Down Sony's PlayStation Network

The temporary attack appears unrelated to recent security breaches of Sony Pictures Entertainment's network

Hackers took down Sony's PlayStation Network for several hours on Sunday night, a company spokeswoman confirmed on Monday.

The attack appears unrelated to recent attacks against Sony's network.

"The ability to access our network services was temporarily impacted due to a distributed denial-of-service attack. We have seen no evidence of any intrusion to the network and no evidence of any unauthorized access to users’ personal information," Jennifer Clark, PlayStation's senior director of corporate and product communications, told The Hollywood Reporter in a statement.

In a distributed denial-of-service attack, a company's computer server is bombarded with numerous requests for information, which can paralyze the network but does not involve accessing it. The recent attacks against Sony Pictures Entertainment involved accessing the network and led to the release of sensitive employee information, including executives' salaries. A hacker group calling itself Guardians of Peace has claimed responsibility for the invasive attacks, while North Korea has denied involvement.

Another hacker group called Lizard Squad took responsibility on Twitter for Sunday's shutdown.

The same group claimed to cause a similar interruption to the PlayStation Network in August.

The PlayStation Network tweeted about the outage Sunday night, which lasted about nine hours, according to its updates.
