The fact about all of these IoT gadgets are connected to the Internet means that sooner or later someone will try to crack them, and unfortunately, hacking IoT devices is usually easier than it should be.
Internet of Things Hacking:-
The network configuration of many IoT devices is often insecure from the start. There is no reason for the port to remain open, and the default login credentials set by the manufacturer are very easy to guess. Changing user names and passwords is often difficult or impossible, and operating systems used by these devices often present some of their own security risks. For hackers, breaking into many IoT devices is a child's game, and the real big problem is that once inside, it is not an easy task to cause serious damage. Unfortunately, we understand all of this from experience.
In 2016, hackers provided themselves with a list of default credentials for various IoT devices. They then scanned the endpoints that opened the Telnet port on the Web (the default configuration for many IoT gadgets). In some less complicated steps, the scammers managed to destroy a large number of Internet connected devices and formed the Mirai botnet. Mirai was later used to launch multiple record-breaking DDoS attacks, and at some point it even knocked down most of the Internet for users on the East Coast of the United States.
This is just one example of how terrible the security of the Internet of Things is. The problem is twofold. On the one hand, your manufacturer does not seem to draw any attention at all. Despite warnings from experts, smart devices are still being shipped with the appearance of security breaches . Even politicians have acknowledged this problem. California recently passed a law prohibiting the use of default passwords on connected devices, indicating that legislators are trying to take action on this. However, experts believe that this may not be enough.
On the other hand, you have users. The Internet of Things is still a relatively new concept for them, and they are not fully aware of the dangers it faces. This means they don't put enough effort into protecting their smart devices, and they don't put pressure on suppliers to properly configure expensive gadgets.
Due to numerous security issues, many people say that we should stop trying to place new "things" on the Internet, but we are not sure if this is a good suggestion. While we have seen that our fair-shared cloud-connected gadgets don't seem to be particularly useful, some innovations can really improve the quality of our lives. However, we all agree that safe, stupid devices are better than vulnerable smart devices.
