The U.S. Department of Homeland Security (DHS) is reportedly assisting in the investigation into the intrusion that may have exposed millions of PSN users' personal data to unauthorized intruders.
"The Department of Homeland Security is aware of the recent cyber intrusion to Sony's PlayStation Network and Qriocity music service," DHS spokesman Chris Ortman told government technology site NextGov. "DHS' U.S. Computer Emergency Readiness Team [CERT] is working with law enforcement, international partners and Sony to assess the situation."
Computer hacking has been an increasing focus for the anti-terrorism department in recent years, but the cabinet-level division is usually focused on foreign and domestic attacks on computer infrastructure critical to government functions or public services.
CERT can help compromised companies restore service and implement new protocols to improve future security in these cases. The group also helps share knowledge of known vulnerabilities with other public and private sector organizations, to prevent similar attacks from happening in the future.
There is some concern among security experts that personal data gleaned from the PSN breach could help hackers with identity theft or cracking schemes focused on corporate or financial services.
