Polymarket front-end compromised through third-party vendor; about $3M of users' pUSD drained
Polymarket disclosed on 25 June 2026 that a breached third-party vendor let attackers inject malicious code into its website for some users. Users who interacted with the compromised front-end had their pUSD (Polymarket's USDC-backed stablecoin) drained; Bubblemaps estimated about $3M taken from fewer than 15 users, and the funds were converted to ETH. Polymarket removed the code and says it will fully refund affected users.

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.

Bonk.fun domain hijacked to serve wallet drainer behind fake terms-of-service prompt
On Mar 11, 2026, attackers who had hijacked a Bonk.fun team account put a wallet drainer on the Solana launchpad's official domain. Visitors were asked to sign a fake terms-of-service message, and those who signed had their wallets drained. The team called losses minimal; SlowMist's database puts them at about $30,000. Only people who signed the fake message on the domain after the hijack were affected. If you signed it, move remaining funds to a new wallet.

Aerodrome and Velodrome front-ends hijacked via DNS, cloned sites serve Eleven Drainer
On 21 November 2025 an attacker changed the DNS records for aerodrome.finance and velodrome.finance, sending visitors to a cloned front-end running 'Eleven Drainer' code. Users who signed on the fake site lost tokens: Blockaid tied about $700K to nine attacker addresses, and Halborn put losses above $1M. The smart contracts were not touched. Anyone who signed on either site that evening should revoke approvals they don't recognise.
