Yahoo has had two breaches, one in early 2014 and now one in late 2016.
The FBI has now announced that this is the largest breach in cybercrime history, with over ONE BILLION accounts being hacked.
How? Apparently, it all started with an unsuspecting “spear phishing” email to a Yahoo employee in early 2014 (read more about spear phishing here). That makes this the biggest known hack of user data ever, and no other hack comes near to it.

The next time you visit Dropbox.com, you may be asked to create a new password. Why? Back in 2012 the cloud storage firm was hacked, and while it thought only email addresses had been stolen, new evidence has come to light that user passwords were compromised, too.
