  We present an MPU-based hotpatching method, MPush, for real-time embedded systems that redirects execution from protected flash regions to RAM-resident patches via HardFault handling. Our demonstration on a syringe pump showed practical viability, with measured overheads of 15 cycles for activation and 136 cycles (46 without optional validations) for redirection. Our results confirm the approach's real-time compatibility. The MPU proves effective for runtime patching in constrained environments; however, system-specific constraints may affect its applicability.

  This poster introduces HarvETHter, a smart contract decompiler for EVM-based platforms such as Ethereum, Binance, and Polygon. We present the corpus completeness hypothesis, which we investigate through HarvETHter. Relying on our hypothesis, HarvETHter sources knowledge of the Ethereum blockchain and leverages it to decompile smart contracts to Solidity source code.
