CoW Swap’s website was hijacked via a DNS attack on April 14 2026, leading the DAO to shut down the frontend and pause backend APIs while warning users to avoid the site and revoke token approvals; the incident knocked the COW token 3% lower to $0.2159【1】.

## DNS hijack shuts down the UI  
The DAO behind CoW Swap announced on X that an unknown party redirected traffic from its official domain (swap.cow.fi) through a DNS hijack, a technique that reroutes users to a malicious look‑alike site. The team responded by locking the domain, flagging the frontend as malicious, and pausing both the website and its APIs as a precautionary measure【2】. While the on‑chain contracts remain intact, the attack creates immediate user‑level risk, prompting Blockaid to advise users not to sign any transactions and to revoke existing token approvals【2】.

## Market reaction and broader context  
Following the announcement, the COW token fell more than 3% to $0.2159, down from $0.2229 the day before【1】. This move mirrors a broader trend of DeFi front‑end attacks; Balancer suffered a similar DNS incident in 2023 and Curve Finance reported multiple hijackings, underscoring the persistent vulnerability of web layers in otherwise secure smart‑contract ecosystems【1】. Hacken’s Q1 2026 report highlighted that phishing and social‑engineering hacks cost Web3 projects $482 million across 44 incidents, reinforcing the financial stakes of such attacks【1】.

## Immediate steps for users  
CoW Swap’s DAO urged users to stay away from swap.cow.fi until the platform is confirmed safe and to revoke any token approvals that may have been granted to the compromised site【1】【2】. The protocol’s core systems, including its backend and APIs, were paused “as a precaution,” but no on‑chain funds were reported as stolen or at risk【2】.

## What to watch
- **Domain status** – monitor whether the swap.cow.fi domain is restored and re‑listed as safe by security services.  
- **COW token price** – watch the $0.2100 support level and the $0.2250 resistance, which bracket recent trading.  
- **Future DNS incidents** – track any further front‑end alerts from Blockaid or similar services that could affect user confidence.

The hijack highlights that even well‑audited DeFi protocols remain exposed at the user interface level; how quickly CoW Swap can secure its domain and restore trust will shape the token’s short‑term trajectory and may influence broader market sentiment toward DeFi front‑end security.
