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.
One of the world's most used cloud-storage services was attacked by hackers -- and not for the first time -- which led to spam messages being sent to email accounts used in some cases exclusively for Dropbox. The security community was quick to claim there had been a data breach, but Dropbox held off with any definitive answers for some days.
Eventually, the firm said that usernames and passwords stolen from other sites, such as LinkedIn, eHarmony, and Last.fm, were used to gain access to some Dropbox accounts. Along with this, a stolen password was also used to access a Dropbox employee's account with passwords as part of an internal project.
The firm then put in place additional security measures and has since implemented two-factor authentication, requiring two proofs of identity, such as those sent to your mobile device.
