A Cardano developer successfully thwarted a DDoS attack, ensuring the blockchain’s stability and even recovering some stolen funds.

The DDoS Attack on Cardano

Late Tuesday, the Cardano blockchain faced a distributed denial of service (DDoS) attack aimed at stealing tokens staked on the network. Despite the attack, the network experienced no downtime and continued to function normally.

Quick Mitigation Efforts

DDoS attacks flood servers or blockchains with spam traffic, disrupting access to online services. Fluid Token’s CTO, @ElRaulito_cnft, reported on X that the attack began at block 10,487,530, with each transaction executing 194 smart contracts. The attacker spent 0.9 ADA per transaction, filling each block with multiple transactions to stress the network.

Market Response

In the wake of the successful defense, ADA’s price saw a modest increase, up 0.4% in the past 24 hours, trading at 38 cents during Asian morning hours.
