“Good enough” emulation: Fuzzing a single thread to uncover vulnerabilities

A Cisco Talos researcher worked around the limitations of hardware-level Code Read-out Protection RDP on the Socomec DIRIS M-70 gateway by pivoting from physical debugging to a "good enough" emulation approach. By focusing on emulating only the single thread responsible for Modbus protocol handli...
