IoT Scanner Checks for Vulnerabilities in Connected Devices
The Dyn DDoS attack last week that shut down parts of the Internet was triggered by bots crafted from compromised connected devices , such as Internet-connected cameras and DVRs, but could theoretically also involve connected routers, printers, and more . While there is no definitive solution for this problem, the IoT Scanner is a tool that can at least tell you if a device in your home is creating a vulnerability.
In the case of last week’s attacks, the botnet was created by taking control of a group of different connected cameras that still had default passwords. To scan if you have such devices on your network, Bullguard Security has created an IoT Scanner . Go to the site, click the scan button, and the IoT Scanner will find open ports on your network.
If the IoT Scanner reports that your network might be compromised, it means that some device connected to your Wi-Fi network has an open port that makes it accessible from the Internet. This can be done on purpose if you have a server or other device that you can access from outside your home network. If you don’t and the IoT Scanner reports that your network might be compromised, then it might be a good idea to dig in and see which device has that open port .
As with most tools of this kind, treat the results with a grain of salt and use them as a starting point to actually protect your network . The IoT Scanner results are vague, but they will at least give you a place to start your search.
