(Reuters) — Past cyber attacks on scores of organizations around the world were conducted with top-secret hacking tools that were exposed recently by the Web publisher Wikileaks, the security researcher Symantec Corp said on Monday.

That means the attacks were likely conducted by the U.S. Central Intelligence Agency.

Symantec said it had connected at least 40 attacks in 16 countries to the tools obtained by WikiLeaks, though it followed company policy by not formally blaming the CIA.
