Popular dogecoin wallet service Doge Vault has confirmed speculation that its service has been hacked by cybercriminals, though it has not revealed how much of customers' deposits have been stolen.

On Monday, Doge Vault shut down its website without revealing why, but on Tuesday it confirmed widespread speculation that it had been hacked. A statement on its website reads:

On the 11th of May, the Doge Vault online wallet service was compromised by attackers, resulting in a service disruption and tampering with wallet funds. As soon as the administrator of Doge Vault was alerted, the service was halted. The attackers had already accessed and destroyed all data on the hosted virtual machines.

We are currently in the process of identifying the extent of the attack and potential impact on user's funds. This involves salvaging existing wallet data from an off-site backup. We will also closely be investigating potential attack vectors, and determining the security breach which enabled the attacker's to compromise the service.

The creator and sole maintainer of Doge Vault, Asad Haider added that customers should not transfer any funds to Doge Vault addresses while his investigation continues. Haider added that he will update customers on the situation with an additional statement - including his findings and plan of action - within the next 24-48 hours.

Haider has not revealed the volume of dogecoin lost in the attack, though some have speculated that it could be as much as 121 million dogecoin, pointing to this mega dogecoin wallet as proof.
