OneLogin, an identity management software company, announced yesterday that it suffered a data breach. Although the firm hasn't provided many details, the few that it has released suggest that the breach is extensive.

Another day, another mega breach. This time, it's social music website Last.fm, which was hacked in 2012 and over 43 million user accounts were compromised. The details of the breach were made public this week by Leaked Source, a website that tracks leaked databases. This comes off the back of revelations that a Dropbox hack that occurred a few years' back let hackers get their hands on over 68 million user credentials. What makes this Last.fm breach worse is that the website used an insecure method to store its user passwords. Here are the details.

The rumours were true; Dropbox was hacked back in 2012 and customer login credentials were compromised. It has now been revealed that over 68 million Dropbox usernames and passwords were stolen. This massive security breach happened because a Dropbox employee reused his account password on other websites. Read on for more details and for lessons that can be learned from this mega breach.
