This is the ultimate security key for professionals.
ZDNet looks back at the year, on a month-by-month basis, at some of the most publicized hacks, leaks and data breaches of 2012.
Online retail store Zappos suffered a significant data breach that exposed the accounts of about 24 million. Security experts thought it was the largest consumer data breach of 2012.
Amazon.com-owned Zappos said hackers attacked an internal corporate network through a Kentucky-based server, and swiped customer account information, including email addresses, the last four-digits of credit card details, and cryptographically scrambled passwords.
