RAR archive of 451 KB whose name points to MobaXterm, a Windows terminal program with SSH and serial-console support, stamped with a 2019-05-23 date and time. Despite being filed as firmware, it is almost certainly a software package or session file rather than a hardware dump. Repair technicians use such a terminal to reach the UART console of routers and embedded boards during flashing or debugging. Check the extracted contents before use, and do not try to program it into any flash chip.
