Our tech team was able to take actions immediately to secure our platform and additional assets. The early incident analysis shows that our cyber security efforts are well structured and secure. Our main server infrastructure, data storages, wallet management and vaults have not been accessed and have not been compromised. The investigation and the identification of the responsible parties is ongoing. We also have identified additional wallet addresses used by the unauthorized party. However, we have been advised to not publicly disclose the ongoing tracking activities at this point in time.
In the past days we have completed setting up a new infrastructure with heightened security. The process of migrating our assets to the new secure vaults has been concluded.
We have begun the gradual rollout of service resumption across our platform. Our main priority was to make certain we resumed in a safe and secure manner, and we appreciate your patience in this regard.
