Federal charges have been announce in the mega security breach at Yahoo. And two of the suspects are Russian agents.

FOX's Jared Halpern has more from Capitol Hill:

A 2014 breach of Yahoo impacted at least half a billion accounts, potentially putting at risk email addresses, birth dates and other personal information.

Acting Assistant Attorney General Mary McCord says the Justice Department has charged four people with the cyberattack, including two officers with the Russian federal security service:

(McCord) "And two criminal hackers with whom they conspired to accomplish these intrusions."

The U.S. has charged foreign nationals with cyberattack before, but this is the first criminal case brought against Russian government officials. It comes amid a separate investigation of Russian efforts to interfere with the 2016 election.
