   "summary": "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."
