Russian spies hack into US electrical grid.

Wasn't this a storyline in 24? From Moscow Times:

Russian cyberspies have penetrated the U.S. electrical grid and left behind software programs that could be used to disrupt the system, the Wall Street Journal reported Wednesday.

The spies also came from China and other countries and were believed to be on a mission to navigate the U.S. electrical system and its controls, the newspaper said, citing current and former U.S. national security officials.

The intruders have not sought to damage the power grid or other key infrastructure but officials said they could try during a crisis or war, the paper said in a report on its web site.

Authorities investigating the intrusions have found software tools left behind that could be used to destroy infrastructure components, a senior intelligence official told the Journal.

"If we go to war with them, they will try to turn them on," he said.

Officials said water, sewage and other infrastructure systems also were at risk.

Protecting the electrical grid and other infrastructure is a key part of a cybersecurity review by President Barack Obama's administration that is to be completed next week.

The sophistication of the U.S. intrusions suggests that China and Russia are mainly responsible, according to intelligence officials and cybersecurity specialists.
