The remainder of the stolen funds are frozen on the attacker's account on exchanges.

We have contacted the authorities and will provide them with our gathered data.

Markets will reopen as soon as we can arrange that the funds on C-CEX will remain frozen.

The balances on the chain have been restored to their legitimate order and users will be able to transact as soon as the markets start.


The attacker tried to extort us on email with the email [email protected] and via pm on bitcointalk as the user MarkedlySuperior.

We'd like to thank Bittrex, C-CEX, Livecoin on their amazing support on a holiday.

Merry Christmas,
Xaurum Team

Update:


All the exchanges have been closed and our blockchain transactions stopped. This means that the attacker can not move his stolen funds.

Our team is doing an analysis of the adressess used to transfer the stolen funds, and have a plan on how to restore the majority of it.

We have had a breach in our RICO website, the hacker has stolen customer funds that were still not withdrawn.

XAUR markets are disabled untill we can remedy the situation. We ask users to help us by stopping transactions, while our team works on a solution.

We will restore the legitimate balance, hopefully soon. We'll keep you updated on the developments.

We apologize for the inconvenience and assure you, that we will solve the problem.

Best regards,
Xaurum Team
