Io.net CEO Ahmad Shadid Discloses Details of Sybil Attack
Io.net CEO Ahmad Shadid recently disclosed details of a Sybil attack on the network, emphasizing the company’s measures to bolster security. According to a postmortem Shadid published on social media, the attackers exploited vulnerabilities to spoof GPU availability and receive rewards of the decentralized computing network based on Solana.
Lessons Learned from Recent Attack
Following the discovery of the April 27 Sybil attack, Io.net’s team conducted a thorough analysis to understand how the attackers were able to exploit the network. The incident began when an unexpected surge in GPU connections was noticed, with approximately 1.8 million fake GPUs trying to connect to the network.
Shadid mentioned, “Over the last 120 hours, we worked to expel sybil attackers from the network, roll out multiple security patches, and put in place a new security model to prevent future incidents. During this time, I worked very closely with the team.”
Exploitation of Vulnerabilities
The attackers had exploited a vulnerability that allowed them to mimic the signals sent by genuine GPUs, thus fooling the network into recognizing them as legitimate. Shadid acknowledged the need for enhanced security measures and transparency within the company.
Enhanced Security and Transparency Measures
The company is actively implementing a series of measures to strengthen network security and restore confidence. Io.net is enhancing the clarity and transparency of its user interface by displaying key metrics on its dashboard, such as total GPUs/CPUs connected and verified GPUs/CPUs that have passed the Proof of Work process.
The technology team is committed to transparency and will publish a list of known issues to keep the public informed, including ongoing bugs and necessary updates. Additionally, the business team is coordinating a network reboot to strengthen supplier relationships and restore the network’s operational capacity.
