If you’ve ever created an account and left a comment on Gizmodo, LifeHacker or any of the Gawker Media sites, this would be a good time to change your passwords, especially if you use the same password on other sites.
A group of hackers called Gnosis launched the attack and comprised passwords have already led to spam on Twitter. The attack has revealed not only the passwords but internal communication traffic on Gawker’s network and FTP information. You can read all about the event here and here and here, but the bottom line is you need to change passwords and learn the lesson that it isn’t a great idea to use the same passwords on multiple sites no matter how convenient it may be.
UPDATE: Here’s a process for you to check if your password has been hacked in this mess.
