Guide to Identify if ISPs are Spying on your IoT devices

By CIOReview | Friday, March 30, 2018

A lot of attacks today happen by tricking a user in different ways—by asking to open a malicious file, clicking on a link, or asking them to enter specific personal information in a fake website. But hacking strategies are a little different when it comes to IoT. This happens partly because often, there is no interface for the user to interact with, but additionally, the devices themselves present poor implementations and vulnerabilities of security measures.

Since, with IoT devices, every manufacturer has their own firmware, designs their architecture, and uses different protocols, understanding the architecture comes first, followed by identifying the components involved, and determining the way devices interact among themselves. The ideal way to do it is by making a diagram of service to find out what could go wrong with every part involved, thus allowing you to define the attack surface and work out the different individual vectors that could be used. Your analysis at this stage can be as precise as you require; try and identify the components that could be useful in helping you search for possible vulnerabilities.

Once you have the diagram and your analysis lab ready, look for the vulnerabilities by seeing how you interact with different components beyond the regular flow. Start with devices meant for communication that are intercepting some traffic entering or exiting the device, through Bluetooth, or Wi-Fi, or even a TV’s remote controller. It is very usual for such devices to send information between some of their components and not request any authentication or use insufficient encryption.
