NSA Denies It Knew About Heartbleed Bug Before It Was Made Public

The National Security Agency says it did not know about a critical security bug until it recently became public.

The NSA was responding to a report from Bloomberg that the agency had known about the vulnerability known as "Heartbleed" for two years and instead of alerting the tech community, it exploited the bug to "gather critical intelligence."

In a statement, the NSA said Bloomberg's report was simply "wrong." The US, the NSA said, would reveal this kind of vulnerability to developers if it ever came upon it.
