[Privacy Protocol Umbra Shuts Down Frontend to Prevent Kelp Attackers from Moving Funds] According to Cointelegraph, the privacy protocol Umbra has shut down its frontend website to prevent attackers from using the protocol to transfer stolen funds from recent attacks. Umbra stated that approximately $800,000 in stolen funds were transferred through its protocol, but the protocol itself is designed only to protect the recipient's identity, not the sender's. All transferred funds remain identifiable. This decision comes days after the Kelp protocol was attacked (with losses exceeding $280 million, suspected to be the work of North Korean hackers). Reports indicate that attackers are attempting to use protocols like Umbra to bridge funds from Ethereum to Bitcoin. Umbra announced that it has placed the hosted version of its frontend into maintenance mode and will restore it once it is confirmed that doing so will not hinder ongoing recovery efforts. However, Umbra cannot prevent anyone from using its smart contracts or the self-hosted version of its open-source frontend.
