Privacy Policy: Umbra shuts down the frontend to prevent Kelp attackers from exploiting its transfer of funds

ME News report, April 22 (UTC+8). Privacy protocol Umbra has shut down its front-end website to prevent attackers from exploiting the protocol to transfer funds stolen in multiple recent attacks. Umbra said that about $800,000 in stolen funds were transferred through its protocol, but the protocol itself is only used to protect the recipient’s identity rather than the sender’s, and all transferred funds can be identified. The decision came a few days after the Kelp protocol was attacked (losses exceeding $280 million, suspected to be North Korean hackers). Reports show that attackers are trying to move funds from the Ethereum to Bitcoin via protocols such as Umbra. Umbra said it has placed its custodial front-end in maintenance mode and will restore it after confirming that it will not interfere with the current fund recovery efforts. However, Umbra cannot prevent anyone from using its smart contracts or the open-source front-end of its self-custody version. (Source: PANews)
