On June 26, the Cardano blockchain successfully defused a DDoS attack against its staked ADA without causing any downtime. The attacker tried to steal tokens by executing a large number of smart contracts, but was discovered and countered by Cardano developers, recovering some funds. The CTO of Fluid Token said the attack started at block 10,487,530, executing 194 smart contracts per transaction and costing the attacker 0.9 ADA per transaction. The founder of Cardano development company Anastasia pointed out that the attack could be stopped immediately by canceling the attacker's staked credentials, which the attacker stopped after seeing the relevant tweets.
