Dough Finance hacked for $1.9 million

Defi platform Dough Finance was hacked for 608 ETH ($1.8 million) by a hacker using a flash loan attack funded through the Railgun privacy service.

Dough Finance sent an on-chain message to the attacker, asking them to return the "misappropriated funds", threatening that they would "pursue all criminal, legal, and administrative avenues available" in the event that the attacker did not do so.
