New IoT-malware grew three-fold in first half of 2018: report Some smart gadget manufacturers are still not paying enough attention to the security of their products.

IoT devices were attacked with more than 120,000 modifications of malware in the first half of 2018, according to the Kaspersky Lab IoT report. That’s more than triple the amount of IoT malware seen in the whole of 2017.

Kaspersky Lab warns that the snowballing growth of malware families for smart devices is a continuation of a dangerous trend: 2017 also saw the number of smart device malware modifications rise to 10 times the amount seen in 2016.

“Compared to personal computers and smartphones, IoT devices might not seem powerful enough to attract cybercriminals and be used in their illegal activity. However, their lack of performance is more than outweighed by their number, and the fact that some smart gadget manufacturers are still not paying enough attention to the security of their products. Even if vendors begin to provide their devices with better security now, it will be a while before old vulnerable devices have been phased out of our homes,” warned notes Mikhail Kuzin, security researcher at Kaspersky Lab.

In addition, IoT malware families are customising and developing very fast, and while previously exploited breaches have not been fixed, criminals are constantly discovering new ones. “IoT products have therefore become an easy target for cybercriminals who can turn simple machines into a powerful device for illegal activity, such as spying, stealing and blackmailing,” Kuzin  added.

The market for IoT devices (also known as “smart” gadgets), and their role in everyday life, is growing exponentially. But cybercriminals are seeing the financial opportunities too, and are multiplying and differentiating their attacks as a result. The danger for consumers who love their IoT gadgets, is that threats can strike unexpectedly, turning seemingly harmless devices into powerful machines for illegal activity. This can include malicious cryptocurrency mining, DDoS attacks, or the discreet inclusion of devices in botnet activities.

Aware of these dangers, Kaspersky Lab experts regularly review the data collected from various sources including our honeypots - decoy devices used to attract the attention of cybercriminals and analyse their activities. The latest updates are striking: during the first half of 2018, the number of malware modifications aimed at IoT devices registered by researchers was more than three times higher than the number registered in the whole of 2017.

The statistics show that the most popular method of IoT malware propagation is still the brute forcing of passwords - repetitive attempts at various password combinations. Brute forcing was used in 93% of detected attacks. In most of the remaining cases, access to an IoT device was gained using well-known exploits.

The devices most often attacking Kaspersky Lab honeypots were routers (by a large margin). 60% of the registered attempts to attack our virtual devices were coming from them. The remaining share of compromised IoT gadgets included a variety of different technologies, such as DVR-devices and printers. The honeypots even registered an attack coming from 33 washing machines.

Different cybercriminals may have different reasons to exploit IoT, but the most popular goal is to facilitate DDoS-attacks by creating botnets. Some malware modifications are also tailored to turn off competing malware, fix its own vulnerabilities and shutdown vulnerable services on the device.
