WASHINGTON - Unspecified nations played a role in a 17-fold jump in cyber attacks on US infrastructure since 2009, but this does not appear to reflect payback for a reported US role in malicious code known as Stuxnet, the head of the Pentagon's National Security Agency said on Thursday.
"I don't see the correlation there at all," Army General Keith Alexander told a security forum in Aspen, Colorado. "I don't see anything that goes to Stuxnet or anything like that."
Stuxnet was the first discovered malware designed to subvert industrial systems. Credited with setting back Iran's disputed nuclear program, it has been reported by The New York Times to have been part of a US and Israeli intelligence operation started under US President George W. Bush and expanded under US President Barack Obama.
Alexander, who also heads the US military's Cyber Command, told the Aspen Security Forum that he was unaware of any evidence that Stuxnet were now being turned against the United States, as some experts have predicted might be the case now that the malware has become available online.
