Privacy Protocol Umbra Shuts Down Frontend to Prevent Attackers from Transferring Kelp-Related Stolen Funds

Odaily News: Privacy protocol Umbra has shut down its hosted frontend website to prevent attackers from using the protocol to transfer stolen funds from a recent security incident. Umbra stated that approximately $800,000 in funds were transferred through its protocol, but the protocol only hides the recipient's identity, and the related transactions can still be tracked on-chain. This measure was taken after the Kelp protocol was attacked, resulting in losses exceeding $280 million. Umbra said it will restore frontend services after confirming that it does not affect asset recovery efforts, but it cannot prevent users from continuing to use the protocol via smart contracts or self-hosted frontends.
