DHS official: Stuxnet a “game changer” – Homeland Security Newswire

A highly complex computer attack that may have been targeting Iran’s nuclear power plants is posing a serious security threat to critical infrastructure worldwide, according to government and cyber-industry experts testifying Wednesday on Capitol Hill.

The computer worm known as Stuxnet was discovered this past July and specifically targets computers that run critical infrastructure such as the electric power grid, water treatment and oil and gas pipelines.

The head of the Cybersecurity Center at DHS said Stuxnet is an incredibly large, complex threat with capabilities never seen before.
