So apparently someone has figured out how to milk people on Mt. Gox, where 80% of bitcoin trades take place, out of real money using DDoS attacks as part of their trading strategy.

It seems even 6 days ago they had a very serious problem. Maybe today it is more of the same? Or maybe things are simply working perfectly.

It's been an epic few days: What happened?
TOKYO - JAPAN - April 04, 2013
Dear Mt.Gox users and Bitcoiners, It’s been an epic few days on Bitcoin, with prices going up as high as $142 per BTC. We all hope that this is just the beginning! However, there are many who will try to take advantage of the system. The past few days were a reminder of this sad truth. Mt.Gox has been suffering from its worst trading lag ever, 502 errors, and at one point some users were not able to log in their account. The culprit is a major DDoS attack against Mt.Gox. Since yesterday, we are continuing to experience a DDoS attack like we have never seen. While we are being protected by companies like Prolexic, the sheer volume of this DDoS left us scrambling to fine-tune the system every few hours to make sure that things don’t go beyond a few 502 error pages and trading lag
Why has Mt.Gox become the target of a DDoS attack?
It is not yet clear who is behind this DDoS and we may never know, but these actions seem to have two major purposes:
• Destabilize Bitcoin in general.
It is not a secret Mt.Gox is the largest Bitcoin exchange with more than 80% of all USD trades and more than 70% of all currencies. Mt.Gox is an easy target for anyone that wants to hurt Bitcoin in general.
• Abuse the system for profit.
Attackers wait until the price of Bitcoins reaches a certain value, sell, destabilize the exchange, wait for everybody to panic-sell their Bitcoins, wait for the price to drop to a certain amount, then stop the attack and start buying as much as they can. Repeat this two or three times like we saw over the past few days and they profit.
What can be done?
Believe it or not, there is pretty much nothing that can be done. Large companies are frequently victims of these kinds of attacks. Even though we are using one of the best companies to help us fight against these DDoS attacks, we are still being affected. There are a few things that we can implement to help fight the attacks, such as disconnecting the trade engine backend from the Internet. By separating the data center from the Mt.Gox website, we will continue to be able to trade...
It seems even 6 days ago they had a very serious problem. Maybe today it is more of the same? Or maybe things are simply working perfectly.
