How to protect your wireless router from malware

O D worries that other people, including criminals, can see his IP address. "What can happen if they come into my router"

As I pointed out last year, your router's IP address is anything but a secret. Every website you visit gets a look at that number. And from that IP address, they can discover your ISP and your general location (your neighborhood, but not your address).

But can they infect your router with malware It's not likely, but the danger is significant enough to take precautions.

Last year, researchers discovered a worm, which they called TheMoon, that infected several Linksys routers. Linksys soon issued a fix to stop it. This wasn't the first such attack, and it will almost certainly not be the last.

Note that TheMoon infected only Linksys routers. I'm not picking on Linksys; the next attack could be on D-Link or Netgear routers. That's the nature of this kind of  malware-- it's manufacturer-specific. So chances are that a worm that tries to attack your router won't be compatible with it--and for once, you can be thankful for incompatibility.

What follows are the basic precautions everyone should take. For more details, read this helpful router security piece by Michael Brown and Jon L. Jacobi.

Finally, if you're really worried, hide your IP address by using either an anonymity browser like Tor, or a virtual private network (VPN) like CyberGhost.
