CoW Swap domain hijacked via registrar social engineering; cloned site drains users through approvals
On 14 April 2026 attackers took control of the domain for swap.cow.fi and sent visitors to a cloned CoW Swap interface that asked for malicious token approvals. CoW DAO paused its backend and APIs and told users to revoke approvals made after 14:54 UTC; the protocol's smart contracts were not affected. Early estimates were about $500K drained; Halborn later put user losses at about $1.2M and said the registrar had been social-engineered.
