A lot of security breaches have just happened.

myspace
linkedin
VK
thumblr
...

You can check or you have been hacked here:

The link is clear and thanks for heads up, but what do you mean with "just happened"?

Most of the big ones happened in one week.
Adobe held the record for being the largest data breach for a long time...

Odd that healthcareDOTgov never makes any mention of being hacked. Maybe they just stay hacked and no one knows the difference.

I like how they spend over half a billion dollar on that website...

I have so much passwords I usually spend 10 minutes playing the game: "guess my own password".
My previous password was 15 characters long and included special characters and numbers.
My new password is 34 characters long and exists of capital and non capital letters.

My new password is a pain to type in though :P
