DDOS strikes BitCoin exchange Mt.Gox
Virtual currency in real trouble
Bitcoin exchange Mt.Gox has been attacked and its servers briefly taken offline.
The service confirmed the attack at 2:00 AM Japan time on April 22nd, posting a tweet to warn users of the outage.
UPDATE: This again appears to be another strong DDos attack. We are working hard to overcome it and will update... fb.me/14J8rINhm— MtGox.com (@MtGox) April 21, 2013
The Facebook post in the tweet describes the incident as a “Layer 7 Ddos” and promises a statement about the incident “later today”. That statement is yet to materialise, but the site was working at the time of writing. It's service was reportedly throttled, and users in Bitcoin forums report slow response to other requests. Mt.Gox says those queues, which have reached more than 20,000 transactions, can be attributed to limits placed on it by its banks.
Others have devised other theories for the delays, with some hypothesising attacks on Mt.Gox are designed to move the price of Bitcoins in ways that favour the perpetrators.
For its part, Mt.Gox says its recent slow performance is not all due to attacks, with an incident on April 10th be attributed to being a “victim of our own success” as huge numbers of new accounts and high volumes of trades have exceeded the capacity of its systems. The Reg awaits its statement about the DDOS with interest. ®
