Acala, the “DeFi hub” of the Polkadot network, suffered a major security breach. The exploit allowed the attackers to mint an additional 1.2 billion aUSD, the native stablecoin of the network, in its iBTC/aUSD liquidity pool. Following the exploit, aUSD depegged and plunged to a low of US$0.009 on 14 August. In response to the incident, Acala passed a proposal to burn US$1.28 billion aUSD to regain the peg. At the time of writing, aUSD is trading around US$0.88.

More than 600 addresses were hit with the same 0.01 ETH ($19.25) ‘dust attack’, including crypto exchanges and public figures.
