Emulating firmware is increasingly popular for systems research, particularly vulnerability research. In this paper we describe how we extend HALucinator to work with real-world systems that use the popular VxWorks RTOS. We describe the Re-hosting Support Layer (its definition and implementation) with the functions necessary to get a Schneider Electric SCADAPack 350 remote terminal unit, a Schneider Electric Modicon 340 programmable logic controller, and Hughes 9201 BGAN inmarsat terminal up and re-hosted (at least partially). We share the process and our path of performing this work over the last year, and give a retrospective approach for re-hosting other RTOSes. We provide a case study with 3 real devices, and show that we can re-host portions of the firmware and perform analyses to show the success of our approach.
