In recent years, we have witnessed a rapid growth of Internet of Things (IoT) devices in our homes and workplaces. These network-connected devices such as smart thermostats, security cameras, light bulbs, and home appliances offer us convenience and efficiency, but they also pose new challenges in terms of cybersecurity. Hackers have set their sights on IoT devices, and in this article we’ll explore why this has happened and what steps we can take to protect ourselves.

The allure of IoT for hackers

Security vulnerabilities

One of the main reasons hackers are focused on attacking IoT devices is the security vulnerabilities inherent in many of these devices. Due to the lack of uniform security standards and the rush to bring products to market, some manufacturers have neglected to implement adequate security measures. This leaves IoT devices open to attack.

Number of IoT devices

The number of IoT devices in use has increased exponentially in recent years. According to estimates, by 2025 there will be more than 75 billion connected IoT devices worldwide. This massive proliferation of devices creates a vast playing field for hackers, as each device represents a potential gateway into a network or system.

Valuable information

IoT devices can collect a lot of valuable information about our lives and habits. From location data and behavior patterns to personal and financial information, these devices store and transmit sensitive data. This makes them an attractive target for hackers looking to obtain valuable information for personal gain or to sell on the black market.

Access to other systems

IoT devices are often connected to other systems on our network, such as routers, servers, or storage devices. By compromising a vulnerable IoT device, hackers can gain access to other systems on the network and expand their attack. This can lead to data theft, information hijacking, or even the interruption of critical services.

Types of attacks on IoT devices

Denial of service (DDoS) attacks

DDoS attacks are a common form of attack on IoT devices. Hackers take advantage of vulnerabilities in devices to infect them with malware and create botnets, networks of compromised devices. These botnets can be used to launch massive attacks that overwhelm an online service, rendering it inaccessible to legitimate users.

Theft of personal information

Hackers can target IoT devices to access valuable personal information. This includes identity data, access credentials, financial information and any other information stored or transmitted by the device. The theft of personal information can have serious consequences, such as identity theft or financial fraud.

Device hijacking

Some hackers seek to hijack IoT devices for ransom or to use them as part of criminal activities, such as sending spam emails or launching cyberattacks. By hijacking an IoT device, hackers gain control over it and can use it for their own malicious purposes.

Manipulation of device operation

Another type of attack on IoT devices is manipulation of their normal operation. Hackers can take control of a device to alter its settings, change its behavior, or even physically damage the device. This can have serious impacts, such as controlling a security system to disable it or sabotaging industrial equipment.

How to protect yourself from attacks on IoT devices

Change default passwords

Many IoT devices come with weak or common default passwords. It is critical to change these passwords to strong, unique passwords as soon as the device is set up.

Pink botnet has more than 1.6 million devices infected

Cybersecurity researchers from Netlab 360 disclosed details of what they say is a super botnet as the largest botnet discovered in the last six years, infecting over 1.6 million devices, mostly located in China, with the goal of launching distributed denial-of-service (DDoS) attacks and inserting advertisements into HTTP websites visited by unsuspecting users.

Mainly targeting MIPS-based fiber routers, the botnet leverages a combination of third-party services such as GitHub, peer-to-peer (P2P) networks, and central command-and-control (C2) servers for its bots to controller communications, not to mention completely encrypting the transmission channels to prevent the victimized devices from being taken over.

The name comes as the sample analyzed contained a large number of function names starting with “pink”, so the discovery team decided to name it pink botnet. The researchers said that Pink code raced with the vendor to retain control over the infected devices, while vendor made repeated attempts to fix the problem, the bot master noticed the vendor’s action also in real time, and made multiple firmware updates on the fiber routers correspondingly.

Pink has also been found adopting DNS-Over-HTTPS (DOH), a protocol used for performing remote Domain Name System resolution via the HTTPS protocol, to connect to the controller specified in a configuration file that’s either delivered either via GitHub or Baidu Tieba, or via a built-in domain name hard-coded into some of the samples.

More than 96% of the zombie nodes part of the “super-large-scale bot network” were located in China, with the threat actor breaking into the devices to install malicious programs by taking advantage of zero-day vulnerabilities in the network gateway devices. Although a significant chunk of the infected devices has since been repaired and restored to their previous state as of July 2020, the botnet is still said to be active, comprising about 100,000 nodes.

With nearly 100 DDoS attacks having been launched by the botnet to date, the findings are yet another indication as to how botnets can offer a powerful infrastructure for bad actors to mount a variety of intrusions. “Internet of Things devices have become an important goal for black production organizations and even advanced persistent threats (APT) organizations,” NSFOCUS researchers said. “Although Pink is the largest botnet ever discovered, it will never be the last one.”
