The Top 10 Security Breaches Of 2012


9. Yahoo

More than 400,000 plaintext Yahoo passwords were posted on the Internet on July 11th. While this is a lower number of victims than the Wyndham Hotels breaches, Yahoo gets bumped up a notch due to the "Tech-Company-Shoulda-Known-Better" factor. The hack appeared to have been focused on the voice services side of the house, but it was widely recommended that anyone with a Yahoo account reset their password immediately. The hackers are believed to have used Union-based SQL injection to collect the data, and they posted the passwords on the Internet as a means of embarrassing Yahoo and making a point about the oftentimes less-than-stellar state of information security.
