VIENNA (Reuters) - The technical sophistication of cybercriminals is swamping the world's ability to cope, a top U.S. official warned on Friday, demanding an accelerated cross-border campaign to combat the security threat.
"Most countries don't even have a legal framework that really governs cyber. It is such a new phenomenon in that regard so the legal systems -- both domestic and international -- have not kept pace with the technological advances we have seen,"U.S. Secretary of Homeland Security Janet Napolitano said.
"And that is just the plain fact of it. We need to accelerate that in response," she told reporters in Vienna.
Prominent cyber attacks of late have targeted the International Monetary Fund, theU.S. Central Intelligence Agency and the U.S. Senate, and companies such asCitigroup and Lockheed Martin Corp.
The attacks have raised questions about the security of government and corporate computer systems and the ability of law enforcement to track down hackers.
Napolitano, in Vienna to address an international security conference, declined to comment on the status of investigations into these cases but stressed countries had to step up their ability to cooperate.
"I would have to say that we are still at the nascent stage. There is no comprehensive international framework" for approaching the issue, she told reporters, adding that the situation was no better in the European Union.
"We are all scrambling but we are scrambling with some of the best minds in the world and we are confident that from a technological point of view we are going to get to a satisfactory resolution of some of these difficult problems.
"Right now there needs to be some sort of international legal framework to address those and that does not yet exist."
A senior Chinese official denied last week there was any cyber warfare going on between China and the United States, after weeks of friction over accusations that China may have launched a string of Internet hacking attacks.
Accusations against China have centered on an intrusion into the networks of Lockheed Martin and other U.S. military contractors, as well as efforts to gain access to the Google email accounts of U.S. officials and Chinese human rights advocates.
Napolitano deferred to the U.S. State Department questions about any heightened security concerns for Americans abroad. She said her department would operate normally even if the U.S. government partially shut down in a row over borrowing limits.
