Forensic narrative
The Polkadot ecological project Acala caused an additional issuance of aUSD due to an error on the chain, allowing attackers to mint aUSD. The vulnerability caused aUSD to lose its peg to the US dollar, initially falling to $0.60 and hovering around $0.90. Acala suspended the protocol shortly after the attack and disabled the transfer of the stolen aUSD and the attackers exchanging Acala tokens for some of the aUSD. Attack method (per SlowMist): On-chain setup error. Reported loss: $ 52,000,000.
