Dear NiceHash users!
Unfortunately, there has been a security breach involving NiceHash website. We are currently investigating the nature of the incident and, as a result, we are stopping all operations for the next 24 hours.
Importantly, our payment system was compromised and the contents of the NiceHash Bitcoin wallet have been stolen. We are working to verify the precise number of BTC taken.
Clearly, this is a matter of deep concern and we are working hard to rectify the matter in the coming days. In addition to undertaking our own investigation, the incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency.
We are fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity.
We would not exist without our devoted buyers and miners all around the globe. We understand that you will have a lot of questions, and we ask for patience and understanding while we investigate the causes and find the appropriate solutions for the future of the service. We will endeavour to update you at regular intervals.
While the full scope of what happened is not yet known, we recommend, as a precaution, that you change your online passwords.
We are truly sorry for any inconvenience that this may have caused and are committing every resource towards solving this issue as soon as possible.
We will keep you updated on any new information we may find on this hack.
