Void Botnet, also referred to as TheVoidStl, is a Rust-based botnet identified in March 2026 that uses Ethereum smart contracts as part of a dual-mode command-and-control architecture. The botnet is notable for combining decentralized, blockchain-backed command-and-control with a centralized web-panel fallback or alternate control path, illustrating a resilient design intended to complicate disruption and infrastructure takedown. Its reported tradecraft includes retrieving command-and-control information from blockchain-hosted smart-contract data through read-only blockchain queries, allowing operators to update backend coordination points without relying exclusively on conventional domain- or IP-based infrastructure. This approach aligns with EtherHiding-style techniques in which malware dynamically resolves active control information from public blockchain data. The use of Rust suggests an emphasis on portability and operational robustness. High-confidence reporting supports Void Botnet’s use of blockchain-enabled command-and-control and centralized management capabilities, but does not provide sufficient corroborated detail on victimology, geographic targeting, sector focus, monetization model, or broader intrusion lifecycle behaviors beyond command-and-control resilience. No confirmed sub-groups are established from the available information.
