There is finally beginning to be more awareness of router security. All of us have routers, large or small; it’s the bridge between ‘The Internets’ and our LAN, and smaller ones have a built-in firewall which many rely on as their only protection.
All routers come with a well-known default username and password, which most people have enough sense to change. This helps prevent not only unauthorized access over the airwaves, but also through the internet itself, although WPA2 should also be turned on for airwaves protection.
Recently there’s been more black hat exploitation of certain brands of small router, specifically Asus and the sorry Linksys and DLink routers. Users often opt for convenience and so turn on Remote Admin… and black hats have automatic worms running around (check at :23 seconds) out there specifically looking for vulns to exploit for fun and profit. NEVER turn on Remote Admin, and it’s not a good idea to turn on router disk sharing as it uses the terrible Windows Server Message Block (SMB) protocol.
