"A government report says a cyberattack against 23 natural gas pipeline operators stole crucial information that could compromise security. Experts strongly suspect China's military."

"Cyberspies linked to China’s military targeted nearly two dozen US natural gas pipeline operators over a recent six-month period, stealing information that could be used to sabotage US gas pipelines, according to a restricted US government report and a source familiar with the government investigation.

From December 2011 through June 2012, cyberspies targeted 23 gas pipeline companies with e-mails crafted to deceive key personnel into clicking on malicious links or file attachments that let the attackers slip into company networks, says the Department of Homeland Security (DHS) report.

The report does not mention China, but the digital signatures of the attacks have been identified by independent cybersecurity researchers as belonging to a particular espionage group recently linked to China’s military."
