For defenders: Treat any F3 V6 as a potential entry point unless manually updated and strictly firewalled.
For researchers: The V6 is an excellent entry-level MIPS target for practicing embedded exploit development – the attack surface is large, and debugging via UART is straightforward (UART pads exist on the PCB near the CPU). The Tenda F3 V6 exemplifies the low-cost router
