One of the most famous forums about Bitcoin has been hacked and defaced by a group of hackers called “The Hole Seekers” to make profit. They say that they have the database which contains information for around 150000 users. The passwords were encrypted with SHA256 which is the same hash algorithm Bitcoin uses. Hackers are selling the database for 25 Bitcoins which is currently about $3000. Site owner on the other hand gives 50 Bitcoins (~$6000) to the first that will find the security hole. Attackers can get that instead or get greedy and receive both rewards. If you had account on Bicoin Talk and you used the same password in an exchange site it is strongly advised to change it or be prepared to loose your money. Bitcoin Talk source code is publicly available so if you can find the security hole you can make a quick profit.
