Everything You Need to Know About Superbug Heartbleed

A coding flaw in the encryption software that underlies much of the Internet was disclosed on April 7, triggering a scramble as Web administrators tried to fix the problem on sites including Yahoo, Facebook, Tumblr and OKCupid.

Although government websites -- including -- appear to have used software that was vulnerable to the Heartbleed bug, all major federal sites avoided exposure, according to the Homeland Security Department. The White House denied speculation that the National Security Agency knew of and exploited Heartbleed.

Although it’s not clear Heartbleed was exploited before it was disclosed to the public, the vulnerability could have allowed hackers to access passwords, chats and other information from websites across the Internet. They also may have accessed information that would enable them to impersonate affected sites that have already implemented the coding patch.
