NEW YORK (CNNMoney) — 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 firmTrustwave 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, Fortune 500) accounts
- 70,000 Gmail, Google+ and YouTube accounts
- 60,000 Yahoo (YHOO, Fortune 500) accounts
- 22,000 Twitter (TWTR) accounts
- 9,000 Odnoklassniki accounts (a Russian social network)
- 8,000 ADP (ADP, Fortune 500) accounts (ADP says it counted 2,400)
- 8,000 LinkedIn (LNKD)accounts
