By the end of 2021, there will be 12 billion connected IoT devices, and by 2025, that number will rise to 27 billion.

All these devices will be connected to the internet and will send useful data that will make industries, medicine, and cars more intelligent and more efficient.

However, will all these devices be safe? It’s worth asking what you can do to prevent (or at least reduce) becoming a victim of a cybercrime such as data theft or other forms of cybercrime in the future?

Will IoT security ever improve?

In recent years, the number of security vulnerabilities related to the Internet of Things has increased significantly.

Let us start at the very beginning — most IoT devices come with default and publicly disclosed passwords. Moreover, the fact is that there are many cheap and low-capacity Internet of Things devices that lack even the most basic security.

And that’s not all — security experts are discovering new critical vulnerabilities every day. Numerous IoT devices undergoing security audits repeatedly exhibit the same issues over and over again: remote code execution vulnerabilities at the IP or even radio level, unauthenticated or broken access control mechanisms.

Weak hardware security is one of the issues that have been discovered most frequently. By this complex term, we refer to all the attack possibilities that hackers can exploit when they have an IoT device in their hands: extracting security credentials stored in clear in the device’s memory → Using this data to breach into the servers where the device’s data is sent → sharing or selling these credentials in the “dark web” to remotely attack other devices of the same type, etc.
