Threat actors exploited the EtherHiding technique to store ClearFake payload routing instructions within smart contracts on the BNB Smart Chain testnet, creating an immutable command-and-control infrastructure that cannot be taken down. The attack began with injected JavaScript on a compromised Swiss website that queried blockchain contracts to deliver malicious payloads. Victims passing anti-analysis checks were fingerprinted by operating system and routed to platform-specific ClickFix social engineering overlays. The campaign simultaneously deployed SectopRAT, a .NET-based remote access trojan capable of browser session hijacking, and ACRStealer, a C++ infostealer targeting credentials and cryptocurrency wallets. An on-chain execution tracker confirmed each compromise in real time. Four smart contracts shared a single deployer wallet, with the oldest deployed nearly a year before analysis, indicating a long-running, actively maintained operation.
