Validator nodes face constant exposure. This deep dive explains how NullRabbit Guard uses eBPF and XDP to enforce security directly inside the NIC driver, dropping scans and abnormal traffic at line rate before they reach the kernel or your node.
Recent Ethereum validator slashings showed how fragile infra can be. Our scan of Sui uncovered something worse: nearly 40% of validator voting power exposed.
NullRabbit's August 2025 scan of the Sui validator set revealed nearly 40% of voting power exposed to SSH, CVEs, and misconfigurations - leaving the network one step away from consensus failure.
Introducing our new research hub where we share insights on DePIN security, blockchain infrastructure, and decentralized network protection.
