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.
On Nov. 24, Trustwave researchers tracked that server,
located in the Netherlands. They discovered compromised credentials for
more than 93,000 websites, including:
- 318,000 Facebook (FB,) accounts
- 70,000 Gmail, Google+ and YouTube accounts
- 60,000 Yahoo (YHOO) accounts
- 22,000 Twitter (TWTR) accounts
- 9,000 Odnoklassniki accounts (a Russian social network)
- 8,000 ADP (ADP,) accounts (ADP says it counted 2,400)
- 8,000 LinkedIn (LNKD)accounts
Trustwave notified these companies of the breach. They posted their findings publicly on Tuesday.
"We don't have evidence they logged into these accounts, but they
probably did," said John Miller, a security research manager at
Trustwave.
