You probably have heard about Internet of Things (IoT) – the idea of inserting intellectual features into little gadget in daily life. Examples are Philips Hue smart bulb, Nike chips for shoes and Petnet smart pet feeder. But have you heard about Botnet of things?
Botnets are networks made up of remotely controlled computers, or “bots”. These computers are infected with malware that allows them to be remotely controlled. Therefore, if your computer is part of a botnet, it is invaded by a certain type of malware that could steal your personal information (e.g. password or confidential documents). (Hoffman, 2016) Botnet has come into existence since 2000. (Schneier, 2017) Although there are multiple ways of defending malware, botnet issues have never been solved. As firewall and it has been getting worse since then. As antivirus software keeps upgrading, new botnets keep appearing.
As many IoT utilize cheap gadgets that have little security, those devices are extremely vulnerable to hackers. (Schneier, 2017) In late 2016, the cyberattack on Dyn’s servers created a network of zombie out of 100,000 connected gadgets. This attack happened because the IoT devices did not have sufficiently effective security protocols to defend malware.
The public has come to realize the severity of botnet issues to IoT. Predicted by firm Gartner, by 2020, 20.8 million connected objects of IoT will invade our daily life. By that time, a major cyberattack could be a disaster since the network covers a huge part of daily gadgets. (Micro, 2017)
How do we mitigate the potential security issue of IoT? One of the solutions is to invest in cybersecurity measures and ensure that companies do take actions to defend malware. The key of this solution is to focus on manufacture of IoT devices, which is also the main issue at this moment. Using home routers is another solution, be it the doorkeeper of the new smart devices at home. Other solutions include creating passwords, regularly changing password, resetting devices to factory settings when malware is suspected. (Micro, 2017) (Internet of Business, 2017)
