2 million Facebook, Gmail and Twitter passwords stolen in massive hack

Hackers have stolen usernames and passwords for nearly two million accounts at Facebook, Google, Twitter, Yahoo and others, according to a report released this week.

The massive data breach was a result of keylogging software maliciously installed on an untold number of computers around the world, researchers at cybersecurity firm Trustwave said. The virus was capturing log-in credentials for key websites over the past month and sending those usernames and passwords to a server controlled by the hackers.
