At InterConnect 2016, attendees can learn more about the vast number of threats the Internet of Things (IoT) is poised to battle in the near future. The bulk of these threats will come in the form of thingbots, which attack connected devices.

Thingbots: The Future of Botnets in the Internet of Things


The Internet of Things (IoT) is upon us. Everything from cars to home appliances, watches and even children’s toys are being connected online. It is projected that by the year 2020, there will be more 25 billion devices connected to the Internet.

Those numbers alone are enough to attract cybercriminals’ attention, but what is more relevant here is what these devices represent. It means more data to steal, more systems to take over and more money to be made.

The Next Evolution of Malware

In the past, this same line of reasoning sparked the evolution of malware. In the dawn of the Internet, we saw the proliferation of mass-mailing worms, when prior to that we had only seen file infectors and macro viruses. When Internet use became increasingly widespread in the early 2000s, financially motivated attackers took notice. That’s when we started seeing the likes of botnets, exploit kits and ransomware. We believe the rise of IoT will bring another evolution in malware in the form of thingbots.

Thingbots are botnets composed of infected IoT devices. These devices can be controlled by an owner to launch attacks, steal sensitive data or facilitate other malicious activities. We have already seen a few of these in the last couple of years.

Beware of Thingbots

Due to their ubiquity and the fact that they are usually connected directly to the Internet, wireless routers and modems are the primary targets for thingbots. Other devices that were targeted included network cameras and network storage systems. Most of these devices use Linux as their operating system, and this allows attackers to take existing Linux malware and recompile it to target the specific architecture the device is running on.

Access was gained on these devices mostly through Telnet default login credentials that the device owners left unchanged. There were also reports of infections through device vulnerabilities, as well. Distributed denial-of-service (DDoS) attacks were the primary use for the infected devices.

We believe that the current crop of IoT malware has not displayed a fraction of its potential yet. We know and expect that it will definitely increase in number, and it’s not a matter of if but how the malware will increase in sophistication. So we ask: What are thingbots capable of in the future? And most importantly, how can we protect ourselves from them?
