What happened

On May 4, 2022, MM Finance's Cronos frontend was compromised and users' transaction outputs were redirected to an attacker-controlled router. The attack affected swaps and liquidity operations for about three hours and caused losses reported at more than $2 million.

How it happened

  1. The attacker altered MM Finance's hosted frontend through a reported DNS-related compromise and inserted a malicious router address.
  2. Users who signed swaps, liquidity additions or removals interacted with the malicious route.
  3. The router redirected transaction outputs to the attacker.
  4. The frontend was taken down after roughly three hours; the opened report describes more than 600 redirected transactions.
