Cardano DDoS Attack Thwarted: Blockchain Security Holds Strong

• Cardano network thwarted a DDoS attack on June 24 without downtime or user impact.
• The attack began at block 10,487,530.
• Community response and security measures ensured continued network functionality.

Cardano proved its resilience and security yet again on June 24th, after successfully deflecting a distributed denial of service (DDoS) attack. This type of cyberattack, designed to overwhelm servers with malicious traffic, failed to disrupt Cardano’s operations or user experience.

“Despite a recent DDoS attack that attempted to disrupt the operation of the Cardano blockchain, the network remained secure, operational, and online. Thanks to the swift actions of developers in the Cardano Community, the attack was mitigated without any downtime or impact on our users,” the network stated via an X post .

DDoS attacks are a common method of cyberattack where the perpetrator floods a server or network with spam traffic to prevent legitimate users from accessing it. In this instance, the attack involved transactions executing numerous smart contracts. 

Through an X post , Fluid Token’s chief technology officer reported that the attack began at block 10,487,530. Each transaction executed 194 smart contracts, with the attacker spending 0.9 ADA per transaction, filling each block with multiple transactions to stress the network.

Ultimately, Cardano not just maintained its integrity, but also had the attacker inadvertently donate to smart contracts audit and development company, Anastasia Labs!

Anastasia founder Philip Disarro noted that the attack could be stopped by deregistering the stake credential used by the attacker. The attack was stopped shortly after Disarro’s post, with some of the attacker’s funds being taken in the process.

“The DDoS attacker halted their attack after reading my tweet in an effort to protect their funds. Unfortunately for them, it was too late, and their funds are already being drained,” he said.

The failed network breach had no significant impact on Cardano’s market trend. ADA is currently trading at $0.4090, reflecting a notable 4.76% increase over the past month.
