Gawker media has now posted an announcement that commenting accounts were compromised. Accounts had been compromised on all Gawker media sites which include: Lifehacker, Gizmodo, Gawker, Jezebel, io9, Jalopnik, Kotaku, Deadspin, and Fleshbot. If you have an account on any of those sites it is strongly recommended that you login and change your password.
The Gawker media sites were attacked by a group originating on 4-Chan called “Gnosis” which are suspected to be responsible for Twitter’s recent attacks as well. Users with accounts at Gawker had the same passwords as their Twitter accounts. So the attack at Gawker prompted another attack on Twitter where a spam message that advertised a “acai berry” diet was spammed from the accounts affected.
So if you have an account on Gawker and your Twitter account password was the same, take the time and change both passwords. Gawker is taking actions to improve security on its infrastructure so this attack will not be as easy in the future.
