Per Cnet article: "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," the Japan-based exchange said in a statement at the time. "Repeat this two or three times like we saw over the past few days and they profit."

Any truth to this, or something deeper behind the scenes?
