If you’re looking to strengthen the Wi-Fi signal in your home or business, be sure the equipment you use doesn’t have a vulnerability that could give free rein to hackers.
IBM X-Force researcher Grzegorz Wypych has found such a firmware flaw, one that would let an attacker execute code remotely without having to log into the wireless device. The vulnerability is in an “extender” — a piece of gear used to expand Wi-Fi coverage — made by networking company TP-Link Technologies. Often available for cheap through electronics retailers, Wi-Fi extenders are used in homes and small businesses to boost connectivity. But, as Wypych pointed out, the extenders can also make their way into larger businesses looking for easy internet access for employees.
