Cow <span>DAO<\/span> issued a <a href=\"https:\/\/x.com\/CoWSwap\/status\/2044091639606522312?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">public warning<\/a> on X at roughly 15:41 UTC, advising users to stop interacting with the site entirely while the team investigated.<\/p>\n<p>A follow-up post at 16:24 UTC confirmed the DNS hijacking and noted that Cow Protocol\u2019s backend and APIs were not affected. The team paused those services anyway as a precaution.<\/p>\n<p>DNS hijacking is a well-known attack method in <span>decentralized finance<\/span> ( <span>DeFi<\/span>). Attackers gain control of domain registrar settings, redirect traffic to a lookalike site, and deploy wallet drainers that trigger malicious transactions when users connect their wallets or sign approvals.<\/p>\n<p>Cow Swap operates as a non-custodial platform, meaning the protocol itself does not hold user funds. <span>Smart contracts<\/span> and on-chain infrastructure were not touched in this incident. The risk was limited to users who visited the compromised frontend and signed transactions after 14:54 UTC.<\/p>\n<p>Cow <span>DAO<\/span> posted guidance at 16:33 UTC <a href=\"https:\/\/x.com\/CoWSwap\/status\/2044089589933965826?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">instructing<\/a> affected users to revoke any approvals granted after that time. The team pointed to revoke.cash as a tool for doing so.<\/p>\n<p>No large-scale confirmed losses were reported as of late afternoon UTC. Community members flagged isolated suspicious transactions, but there was no evidence of a systemic drain affecting the broader protocol.<\/p>\n<p>Security tool Blockaid <a href=\"https:\/\/x.com\/blockaid_\/status\/2044087924442997184?s=20\" target=\"_blank\" rel=\"noopener noreferrer\">flagged<\/a> swap.cow.fi and related domains, including cow.fi during the incident window. The team continued monitoring through approximately 18:15 UTC and asked users with potentially affected transactions to submit their transaction hashes for review.<\/p>\n<p>As of the latest available information, the protocol remained paused, and Cow <span>DAO<\/span> had not confirmed full restoration or released a post-mortem.<\/p>\n<p>Frontend and DNS attacks have targeted several <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-defi-decentralized-finance\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">DeFi<\/a> protocols in recent months.
