What types of attacks are most commonly aimed at home IoT devices?

Attack types

Home IoT devices are most frequently targeted by DDoS attacks, data interception and spoofing, exploitation of firmware vulnerabilities, and hacking through weak passwords and open ports. For example, the Mirai botnet in 2016 used infected cameras and routers to generate peak traffic of 1 Tbps, marking one of the earliest large-scale DDoS incidents in the IoT world. There are also known cases of data interception on smart locks such as the August Smart Lock Pro, priced from 18,000 ₽, where attackers can gain access to a home by spoofing signals.

Targeted devices

The main targets of attacks are surveillance cameras, routers, and smart locks, as well as devices with outdated or unpatched firmware. For instance, Xiaomi devices from the Mi Smart Home series often suffer from exploited vulnerabilities precisely because of missing timely updates. According to Kaspersky analytics (2026), about 70% of home IoT devices still use default passwords, which significantly eases hacking via open ports and lowers the overall network security level.

• DDoS attacks: peak traffic up to 1 Tbps (Mirai botnet, 2016)
• August Smart Lock Pro smart locks: from 18,000 ₽, vulnerable to data spoofing
• Xiaomi Mi Smart Home: frequent firmware vulnerabilities due to lack of updates
• 70% of home IoT devices use default passwords (Kaspersky, 2026)

How to properly choose and configure devices to reduce hacking risks?

Device selection

To reduce hacking risks in a home IoT system, choose devices that receive regular OTA updates to ensure security relevance. For example, the Google Nest Hub receives monthly updates, significantly reducing the chance of exploitation of known vulnerabilities. Pay attention to security certifications such as UL 2900-1 or ISO/IEC 27001, which confirm compliance with international information security standards.

• Google Nest Hub — monthly updates;
• UL 2900-1 and ISO/IEC 27001 certifications for manufacturers;
• Price for Zyxel Keenetic routers with UPnP disable option from 5,000 ₽.

Security settings

Proper device configuration includes enabling two-factor authentication (2FA), available in ecosystems like Samsung SmartThings and Apple HomeKit, which reduces the chance of unauthorized access. An important step is disabling UPnP on routers, such as Zyxel Keenetic, preventing automatic opening of external ports and minimizing attack entry points from outside.

• Two-factor authentication in Samsung SmartThings and Apple HomeKit;
• Disabling UPnP on Zyxel Keenetic routers (cost from 5,000 ₽).

What software and hardware protection tools are effectively used in home IoT networks?

Protection software

Effective protection of home IoT networks requires installing specialized software with traffic filtering and antivirus capabilities that can detect attacks on smart devices. An example is Kaspersky Internet Security Plus with an IoT protection module, costing about 2,500 ₽ per year and providing network connection scanning to prevent malware infection. It’s also useful to use routers with advanced built-in features, such as the ASUS RT-AX86U, priced around 15,000 ₽, supporting firewall and traffic filtering at the router level.

Hardware solutions

Hardware tools like routers with network segmentation capability and specialized security gateways significantly enhance protection levels. For instance, the MikroTik hAP ac² (about 9,000 ₽) allows creating VLANs and separate Wi-Fi networks for IoT devices, limiting threat spread inside the home network. More expensive devices, such as the Norton Core Secure WiFi Router priced around $250, offer comprehensive network traffic monitoring and automatic blocking of suspicious activities, boosting smart home security.

• Norton Core Secure WiFi Router — $250, threat monitoring and blocking

Why are standard protection methods sometimes insufficient and what user mistakes are most common?

User mistakes

The main user errors leading to vulnerabilities of home IoT devices are neglecting basic security rules. About 40% of owners do not change factory passwords, greatly easing attacker access (ESET report, 2026). Additionally, many use the same password for multiple devices and online services, increasing the likelihood of simultaneous compromise of several systems if data leaks occur.

Another common mistake is improper remote access configuration: open Telnet and SSH ports are often left unencrypted, allowing data interception and device control takeover. Ignoring regular firmware updates is another vulnerability since manufacturers regularly release patches to fix known security holes, yet 35–40% of users do not install them promptly due to inconvenience or lack of notifications.

Limitations of standard measures

Standard protection methods such as password changes and regular updates aren’t always enough due to configuration complexity and low user awareness. Many devices, for example popular TP-Link Deco models, come with basic security settings that require manual adjustment for effective protection.

• Factory passwords: 40% of devices remain with default credentials (ESET, 2026)
• Firmware updates: 35–40% of users don’t install patches on time
• Remote access: open Telnet/SSH ports without encryption increase hacking risk

Improving security requires a comprehensive approach that includes not only basic measures but also specialized monitoring tools and network segmentation that protect devices even if users make mistakes.

What legislative and standard requirements regulate IoT security in Russia and worldwide?

Russian regulations

In Russia, IoT device security is mainly regulated by GOST R 57580.1-2017, which sets mandatory data protection requirements including compulsory communication encryption and regular software updates. Federal Law No. 187-FZ of July 27, 2010, on information security also applies to IoT systems, providing the legal framework for personal data protection and preventing unauthorized access. Since 2025, mandatory labeling of IoT devices under FSTEC Russia requirements is in effect, enabling control over device compliance with cybersecurity standards and facilitating identification of vulnerable models on the market.
