IoT Scanner Checks for Vulnerabilities In Your Connected Devices
Last week's DDoS attack on Dyn
that shut down portions of the internet was fueled by
bots created from hacked connected devices
like internet-connected cameras and DVRs,
but can also theoretically include
connected routers, printers, and more
. While there's not exactly a fix for this problem, IoT Scanner is a tool that can at least tell you if a device in your house is creating a vulnerability.
In the case of last week's attacks, the botnet was created by taking control of a bunch of different connected devices that still had the default passwords in use. To scan if you have such devices in your network, Bullguard
If IoT Scanner comes back saying that your network can be breached, that means some device that's connected to your Wi-Fi network has an open port that makes it accessible from the internet. This could be on purpose if you're running a server or have some other device that you can access from outside your home network. If you're not doing that and IoT Scanner says your network can be breached, then it's a good idea to dig in and see which device has that open port .
