Privacy Policy Umbra shuts down the frontend to prevent attackers from transferring Kelp-related stolen funds
ChainCatcher messages, privacy protocol Umbra has shut down its hosted front-end website to prevent attackers from exploiting the protocol to transfer stolen funds involved in recent security incidents.
Umbra said that around $2.8 billion in funds were transferred via its protocol, but the protocol is only used to hide the recipient’s identity and the related transactions can still be traced on-chain. This measure was implemented after the Kelp protocol was attacked, which led to losses of over $2.8 billion. Umbra said it will restore front-end 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 front ends.
