Kaspersky blocked over 330 thousand attacks on IoT devices in the Middle East in 2022

Over 2022, Kaspersky detected and blocked 337,474 cyberattacks on Internet of Things (IoT) devices in

the Middle East. All these attacks were blocked on Kaspersky honeypots – decoy devices used to attract

the attention of cybercriminals and analyze their activities.

IoT devices include wearables, smart home appliances, smart city systems, self-driving cars, automated

retail checkouts, and other smart devices for home and business use. These devices can collect and

transfer data over a wireless network without human input. Cybercriminals use networks of infected smart

devices to conduct DDoS attacks or as a proxy for other types of malicious actions.

The number of attacks on IoT devices has been increasing exponentially over the last years. This is

related both to the activity of criminal actors and to the increasing number of IoT devices that are in use.

According to open research, in 2020 there were 171 million IoT devices operating in the Middle East. By

2030, the number is expected to reach 729 million 1 . Capitalizing on weak security of IoT devices,

cybercriminals are intensifying their attacks.

A brute force attack uses trial-and-error to guess login & password info or encryption keys, with hackers

working through all possible combinations to guess correctly. Throughout 2022 in the Middle East there

were over 113,000 attempts to brute force logins and passwords to IoT devices using only the most

popular combinations (examples are provided in the table below); the total number of brute force attempts

is even higher.

 

Examples of the most popular brute force login combinations for IoT devices

 

in the Middle East region:

 

Username Password Count of brute force

attempts

nproc nproc 21409

shell sh 11948

admin admin 5383

admin adminpass 3272

root root 6028

root 12345 4664

 

“As the number of IoT devices grows and attacks intensify, cybercriminals use both advanced and simple

tactics to infiltrate smart devices. One of these tactics is using simple password and login combinations –

our research showed that on hundreds of thousands of IoT devices the most common login-password

combinations are admin-admin, guest-guest, or other variants that come as default on different kinds of

equipment,” commented Vladimir Dashchenko, security expert at Kaspersky ICS CERT 2 . “It is easy to

change the default password, so we urge everyone to take this simple step towards securing your smart

devices. Speaking of more thorough protection, IoT vendors should consider implementing the next

generation cybersecurity approach in their products – where devices would feature innate, built-in

protection that would make them Cyber Immune. Such technology is already available on the market,

including offers from Kaspersky. For instance, Kaspersky IoT Secure Gateway system is designed to

serve as a secure gateway for the Internet of Things on an enterprise network.”

Given the diversity of IoT devices and their related cybersecurity risks, the need for their protection is

clear, especially when it comes to smart cities or critical infrastructure. Traditional measures are not

sufficient for IoT protection, making it crucial that specialized security solutions are implemented.

To keep your devices safe, Kaspersky recommends users:

 Install updates for the firmware you use as soon as possible. Once a vulnerability is found, it can

be fixed through patches within updates.

 Periodic rebooting will help get rid of malware already installed (although in most cases the risk of

reinfection will remain).

 Change the factory passwords at initial setup, use complex passwords at least 8 characters long,

including upper and lower-case letters, numerals, and special characters.

 Use a strict access policy, network segmentation and a zero-trust model. This will help minimize

the spread of an attack and protect the most sensitive parts of the infrastructure.

 Check the IoT Security Maturity Model – an approach that helps companies evaluate all steps

and levels they need to pass to achieve a sufficient level of IoT protection.

 Use a dedicated IoT gateway that ensures the inbuilt security and reliability of data transferring.

For instance, Kaspersky IoT Secure Gateway is Cyber Immune, which means almost no attack

can affect the gateway’s functions.

 Use Kaspersky Threat Intelligence to block network connections originating from malicious

network addresses detected by security researchers.
