Android TV Users Watch Out: Dangerous Vo1d Botnet Hits 1.6 Million Devices

Hackers are upping their game, getting better through attacks and strategies. The latest incident of this rise is the disturbing spread of the Vo1d malware botnet. Vo1d is a highly sophisticated malware and infected around 1,590,299 Android TV devices throughout 226 countries, changing them into “anonymous proxy servers" for malicious activities. 

Why is Vo1d malware so dangerous?

Vo1d is considered dangerous because of its persistence and potential to expand despite earlier discoveries by cybersecurity experts.

Research by Xlab suggests Void had 800,000 active bots, “Peaking at 1,590,299 on January 14, 2025.” Experts believe the botnet is being rented to hacking groups for various illegal activities, from escaping regional internet restrictions to ad frauds. 

Vo1d’s campaign trend suggests that the devices are leased out and then returned, causing a sharp rise and fall in the number of active bots in particular regions. The highest impact has been noticed in South Africa, Argentina, Brazil, China, and Thailand.

About Vo1d Malware 

Vo1d is not your average Joe, it is one of the most advanced and biggest malware in recent years, outperforming deadly botnets such as Bigpanzi and Mirai. Its Command and Control (C2) framework uses 2048-bit RSA encryption and Domain Generation Algorithms, making it indestructible. Vo1d uses 32 DGA seeds to create over 21,000 C2 domains, making it operational despite attempts to close its network.

It transforms infected devices into proxy servers, allowing threat actors to reroute malicious traffic via infected devices, hiding their source location and escaping detection. 

The proxies are then used for various illegal activities such as:
  1. Illegal Transactions
  2. Security evasion 
  3. Advertising Frauds

What makes Vo1d even more dangerous is its evolving nature

V01d is considered a severe threat due to its “evolving nature”. According to Forbes, the “latest version includes enhanced stealth capabilities and custom XXTEA encryption, further complicating detection and removal efforts.” In case researchers can register a C2 domain, they “can’t issue commands to disable the botnet due to the strong encryption measures in place."

The malware also uses special plugins like Mzmess SDK, used for ad-clicking scams. The SDK allows the botnet to mimic “human-like” interface, scamming advertising networks into payments. Vo1d can also harvest system data such as IPs, device specs, and network info from compromised devices. This can trigger further attacks. 

Evolution of Vo1d malware

Another important highlight about Vo1d’s expansion is its attack strategy. Although the experts don't know the infection vector, they believe the malware distributes via harmful firmware updates, Android TV system vulnerabilities, or sideloaded apps. Experts also suspect that illegal streaming services and infected third-party app stores may contribute to spreading the malware.

Tips to Stay Safe

IoT and Android TV users should follow these precautions to lower the chances of attacks:
  1. Update update update! Hackers exploit vulnerabilities in outdated software. 
  2. Buy IoT devices and Android TV from authorised manufacturers. Avoid third party sellers. 
  3. Disable “remote access” (if enabled) on your Android TV and IoT device, unless absolutely needed. 
  4. Only install apps from Google Play Store. Avoid installing apps from third-party.
  5. Disconnect inactive devices from the internet, if not in use.
  6. Use a network monitoring tool to identify malicious internet traffic patterns and find out about a compromised device.

Users should be more careful

Xlab warns about the dangers of Vo1d malware, “Many users harbor misconceptions about the security of TV boxes, deeming them safer than smartphones and thus rarely installing protective software.” 

Higlighting the dangers of using modded apps and software, Xlab says the “widespread practice of downloading cracked apps, third-party software, or flashing unofficial firmware—often to access free media—greatly increases device exposure, creating fertile ground for malware proliferation.”

Huge Data Leak Puts 2.7 Billion Records at Risk – What You Should Know

 



A security issue has surfaced involving an unprotected database linked to Mars Hydro, a Chinese company known for making smart devices like LED grow lights and hydroponic equipment. Security researcher Jeremiah Fowler discovered this database was left open without a password, exposing nearly 2.7 billion records.


What Data Was Leaked?  

The database contained sensitive details, including WiFi network names, passwords, IP addresses, and device identifiers. Although no personal identity information (PII) was reportedly included, the exposure of network details still presents serious security risks. Users should be aware that cybercriminals could misuse this information to compromise their networks.


Why Is This Dangerous?  

Many smart devices rely on internet connectivity and are often controlled through mobile apps. This breach could allow hackers to infiltrate users’ home networks, monitor activity, or launch cyberattacks. Experts warn that leaked details could be exploited for man-in-the-middle (MITM) attacks, where hackers intercept communication between devices. 

Even though there’s no confirmation that cybercriminals accessed this database, IoT security remains a growing concern. Previous reports suggest that 57% of IoT devices have critical security weaknesses, and 98% of data shared by these devices is unencrypted, making them prime targets for hackers.


Rising IoT Security Threats  

Cybercriminals often target IoT devices, and botnet attacks have increased by 500% in recent years. Once a hacker gains access to a vulnerable device, they can spread malware, launch large-scale Distributed Denial-of-Service (DDoS) attacks, or infiltrate critical systems. If WiFi credentials from this breach fall into the wrong hands, attackers could take control of entire networks.


How Can Users Protect Themselves?  

To reduce risks from this security lapse, users should take the following steps:

1. Update Device Passwords: Many IoT gadgets use default passwords that are the same across multiple devices. Changing these to unique, strong passwords is essential.

2. Keep Software Up-to-Date: Manufacturers release software patches to fix security flaws. Installing these updates regularly reduces the risk of exploitation.

3. Monitor Network Activity: Watch for unusual activity on your network. Separating IoT devices from personal computers and smartphones can add an extra layer of security.

4. Enhance Security Measures: Using encryption tools, firewalls, and network segmentation can help defend against cyberattacks. Consider investing in comprehensive security solutions for added protection.


This massive data leak stresses the importance of IoT security. Smart devices provide convenience, but users must stay proactive in securing them. Understanding potential risks and taking preventive measures can help safeguard personal information and prevent cyber threats.

Addressing the Security Risks Posed by IoT Devices

 


There has been a marked change in daily life as a result of the proliferation of IoT devices, and Transforma Insights estimates that 14 billion such devices are connected globally, indicating that this type of technology has profound effects. In today's modern lifestyle, the Internet of Things has become deeply integrated into our everyday lives, from smart home appliances to advanced automotive systems. IoT-enabled technology is increasingly prevalent thanks to the ubiquity of smartphones and wearables, which means that individuals are interacting with it nearly constantly. 

Although these interconnected devices are convenient and efficient for consumers, they also represent serious cyber threats, particularly for insurers and the people they insure on commercial policies. A growing reliance on the Internet of Things is being met with a growing number of threats, making it imperative to develop robust risk management strategies and implement enhanced protection mechanisms to combat these threats as they emerge. 

There is a vast network of internet-connected devices being used in the Internet of Things (IoT), which collects and exchanges data across a wide array of different devices, from smart appliances to systems critical to infrastructure. The Internet of Things involves making sure that devices are properly inventoried, visible and secure within interconnected ecosystems to ensure that they are monitored and controlled, as well as providing your data with the appropriate level of protection. We call this IoT security. Although IoT security is of the same kind as traditional network security, it is more complex as a result of the high stakes connected with IoT systems.

There is a serious risk of cyber attacks associated with IoT devices, as they can control power plants, healthcare systems, and surveillance systems differently than standard computers can. Security measures, authentication protocols, and proactive risk management are essential for safeguarding these systems from potential breaches that could have severe consequences if not taken care of promptly. There has been an explosion of the Internet of Things (IoT), which embraces a broader range of applications than just consumer applications, including critical sectors such as healthcare, utilities, and transport,t when it comes to security vulnerabilities. This has far-reaching consequences, both for consumers and for these sectors. 

In industries such as banking, health care, and information technology, data breaches can hurt the reputation of the organization, resulting in the loss of sensitive personal data, disruption of operations, and the potential for more serious problems. IoT technology is becoming increasingly reliant on security frameworks as a consequence of its use, and as a consequence, we need to reassess them. There is a need to strengthen device security, implement more rigorous industry standards, and create a culture in which security is valued, as these are crucial steps that will allow industries and infrastructure to be protected from threats. 

IoT has fundamentally changed industries across the globe, transforming them from devices that were initially used in smart homes to a system that is designed to integrate agricultural practices, healthcare, transport, and manufacturing all in one intricate, interconnected ecosystem. The Internet of Things has the potential to transform businesses, automate complex processes, and increase operational efficiency at unprecedented scales by enabling real-time decision-making and automating complex processes. However, despite its transformative potential, significant security vulnerabilities pose substantial risks, which may undermine its potential.

IoT devices often lack the basics of security, such as encryption, regular firmware updates, and secure boot processes, which leaves them vulnerable to cyber threats if they are not secured. In addition to the overwhelming number of IoT devices being deployed, cyber attackers can exploit each device as a potential entry point for a cyber attack. This makes the situation even more difficult. Once an IoT device is compromised, it can serve as a gateway for more critical systems that enable malicious actors to take advantage of the interconnected nature of networks and escalate security breaches across interconnected networks. Because infrastructures are interconnected, there is a greater risk of widespread vulnerabilities cascading into the entire infrastructure, which can lead to compromise.

There is an urgency for security gaps, as well as a need to take a comprehensive approach that includes the development of robust authentication protocols, standardizing security measures across industries, and committing to continuous risk assessment as a proactive measure. In a rapidly evolving digital ecosystem driving innovation and efficiency, it is important to protect these devices from emerging cyber threats to ensure the integrity and resilience of the ecosystem as it continues to grow. IoT devices have grown rapidly over the past few years, providing businesses with considerable convenience and operational efficiency as a result of their internet-connected nature. This expansion, however, presents significant security challenges that must be addressed if sensitive information is going to be safeguarded and essential infrastructure is going to be protected from malicious threats posed by cybercriminals. 

Weak default passwords pose a primary vulnerability, as well as insufficient software updates and a breach in data protection can all lead to unauthorized access, operational disruptions, and serious security breaches, all of which pose a serious threat. Since IoT systems are increasingly being relied upon for several tasks, effective measures must be implemented to mitigate cyber risks and increase the defences against potential cyberattacks. As a result of the use of robust authentication methods like multi-factor verification and biometric authentication, IoT systems need to be protected from unauthorized access.

A rigorous application of encryption protocols is required for secure data exchanges to ensure that sensitive information is protected from interception and exploitation. As a further step towards strengthening IoT security frameworks, the use of encryption protocols and firewalls can also be used to establish secure network connections. Furthermore, IoT devices need to be regularly updated and constantly monitored to be able to detect vulnerabilities and to be able to respond proactively to potential threats. 

A further enhancement to IoT infrastructure protection is the implementation of physical security measures, including tamper-resistant device designs and secure storage solutions. IoT ecosystems can only be strengthened by utilizing a comprehensive, multi-layered approach that integrates policy enforcement, software security, and network segmentation. In an increasingly interconnected digital environment, organizations need to take steps to mitigate cybersecurity risks to ensure IoT systems remain secure, resilient, and capable of sustaining critical operations to combat emerging cyber threats. 

IoT (Internet of Things) adoption is becoming more and more prevalent in both personal and industrial environments, thus posing the need to consider the associated security risks critically. In today's ever so complex and interconnected world, every interconnected device presents a unique set of challenges, leading to the need for companies and governments to adopt a proactive and comprehensive security strategy to ensure sensitive data is protected, system integrity is maintained, and unauthorized access is prevented. There is no single approach to IoT security, and the framework should incorporate multiple elements that encompass device discovery, risk analysis, and continuous monitoring as part of the overall approach.

To ensure effective security management, it is essential to identify and classify all connected devices so that visibility and control can be maintained across the entire network. As a result of conducting comprehensive risk assessments, organizations may be able to identify vulnerabilities in real-time and implement targeted security measures to mitigate any potential threats to their business. For continuous protection to be ensured, regular monitoring and sophisticated defence mechanisms are essential, allowing rapid detection of emerging cyber risks and enforcing rapid response to them. 

It is imperative for maximizing IoT security that advanced security tools and platforms are incorporated into the design. As organizations are aware of the importance of cybersecurity, solutions such as Continuous Automated Asset and Security Management (CAASM) and Cyber Risk Quantification (CRQ) provide an organization with the capability of automatically identifying and profiling IoT devices as well as dynamically assessing risks and implementing effective security protocols. Utilizing these advanced technologies can enable organizations to enhance their cybersecurity posture, minimize the exposure of their IoT ecosystems to cyber threats, and ensure the resilience of their system against cyberattacks. 

IoT security should be viewed as a strategic and systematic approach to mitigate risks, maintain a secure digital infrastructure and mitigate the potential risks of the Internet of Things. Investing in cutting-edge security solutions will empower businesses to take proactive moves in addressing vulnerabilities, assuring network defences are strengthened, and safeguarding critical assets in the face of an ever-evolving cyber threat landscape.

Three Ways to Safeguard Your Smart Home From Cybercriminals

 

Your smart home is a technological marvel. However, when camera flaws allow our neighbours to spy on us, smart speakers are manipulated with lasers, robot vacuums are breached to shout obscenities, and entire security systems are compromised by a smart plug, it's fair if you're hesitant to link your home to the internet. 

However, there is no reason to completely forgo the benefits of smart home devices. The idea is to recognise the risks and make use of available security features. Whether you have a network of smart kitchen gadgets or a single voice assistant, these measures will ensure that no one messes with your belongings. 

Secure your wi-fi network 

The majority of routers come with a model-specific SSID and either a random password or something generic, such as "admin," making it easier for cybercriminals to gain access to your home Wi-Fi and snoop about your linked smart home devices. Keep in mind that these manufacturer-supplied credentials are available online for anybody to use, so the first step is to secure your Wi-Fi network with a strong password. 

The process differs slightly depending on the device, but the basics are the same; here's how to get started. Those employing a mesh system will be able to manage security settings via a handy smartphone app. If your router supports it, consider altering the SSID, which is simply the name of your Wi-Fi network (e.g., PCMag_Home). While older devices are limited to WPA2, newer routers support the more secure WPA3 protocol. 

Replace outdated routers

You presumably purchased a new phone or laptop during the last several years. But how about your router? Has it accumulated dust on a shelf for far too long? If your internet performance isn't already hurting, the security of your linked gadgets very likely is. 

An ageing router indicates ageing security protocols—and an easier access point for undesirable actors. If you need a new router, the latest home internet standard is Wi-Fi 6. Prices for Wi-Fi 6 routers have dropped dramatically in recent years, with more alternatives available. Meanwhile, Wi-Fi 7 is still in its early stages of release. Check out our reviews of the finest wireless routers, gaming routers, and mesh networks.

Manage your account passwords

After securing the Wi-Fi network, it's time to safeguard the individual devices and services that connect to it. Numerous smart gadgets are managed by a smartphone app, so you'll need to create an account for each one. Using the same password for everything is handy, but it also poses a security risk.

If one of those accounts is compromised and the password is revealed, hackers may gain access to all of the other accounts on which you used that password. Instead, create a one-of-a-kind password that no one else will be able to guess. You may use a random password generator to generate difficult-to-guess codes, and a password manager to remember them all for you.

2.8 million IP Addresses Being Leveraged in Brute Force Assault On VPNs

 

Almost 2.8 million IP addresses are being used in a massive brute force password attack that aims to guess the login credentials for a variety of networking devices, including those generated by Palo Alto Networks, Ivanti, and SonicWall.

A brute force assault occurs when an attacker attempts to repeatedly log into an account or device with many usernames and passwords until the correct combination is found. Once the malicious actors access the right credentials, they can use them to access a network or take control of a device.

The Shadowserver Foundation, a threat monitoring platform, reports that a brute force attack has been going on since last month, using around 2.8 million source IP addresses every day to carry out these attacks. Brazil accounts for the majority of them (1.1 million), with Turkey, Russia, Argentina, Morocco, and Mexico following closely behind. However, a very big range of countries of origin generally participate in the activity.

These are edge security equipment, such as firewalls, VPNs, gateways, and other security appliances, which are frequently exposed to the internet to allow remote access. The devices used in these attacks are predominantly MikroTik, Huawei, Cisco, Boa, and ZTE routers and IoTs, which are frequently hacked by big malware botnets. 

The Shadowserver Foundation stated to the local media outlet that the activity has persisted for some time but has recently escalated significantly. ShadowServer also indicated that the attacking IP addresses are distributed across various networks and Autonomous Systems, suggesting the involvement of a botnet or an operation linked to residential proxy networks. 

Residential proxies are IP addresses allocated to individual customers of Internet Service Providers (ISPs), rendering them highly desirable for cybercrime, data scraping, circumvention of geo-restrictions, ad verification, and ticket scalping, among other uses. 

These proxies redirect internet traffic over residential networks, giving the impression that the user is a typical home user rather than a bot, data scraper, or hacker. Gateway devices targeted by this activity may be utilised as proxy exit nodes in residential proxying operations, passing malicious traffic through an organization's enterprise network. These nodes are rated "high-quality" because the organisations have a good reputation and the assaults are more challenging to identify and stop. 

Changing the default admin password to a strong and distinct one, implementing multi-factor authentication (MFA), employing an allowlist of trustworthy IPs, and turning down web admin interfaces when not in use are some ways to defend edge devices against brute-forcing assaults. In the end, patching those devices with the most latest firmware and security upgrades is essential to eliminating flaws that threat actors could use to gain initial access.

Understanding and Preventing Botnet Attacks: A Comprehensive Guide

 


Botnet attacks exploit a command-and-control model, enabling hackers to control infected devices, often referred to as "zombie bots," remotely. The strength of such an attack depends on the number of devices compromised by the hacker’s malware, making botnets a potent tool for large-scale cyberattacks.

Any device connected to the internet is at risk of becoming part of a botnet, especially if it lacks regular antivirus updates. According to CSO Online, botnets represent one of the most significant and rapidly growing cybersecurity threats. In the first half of 2022 alone, researchers detected 67 million botnet connections originating from over 600,000 unique IP addresses.

Botnet attacks typically involve compromising everyday devices like smartphones, smart thermostats, and webcams, giving attackers access to thousands of devices without the owners' knowledge. Once compromised, these devices can be used to launch spam campaigns, steal sensitive data, or execute Distributed Denial of Service (DDoS) attacks. The infamous Mirai botnet attack in October 2016 demonstrated the devastating potential of botnets, temporarily taking down major websites such as Twitter, CNN, Reddit, and Netflix by exploiting vulnerabilities in IoT devices.

The Lifecycle of a Botnet

Botnets are created through a structured process that typically involves five key steps:

  1. Infection: Malware spreads through phishing emails, infected downloads, or exploiting software vulnerabilities.
  2. Connection: Compromised devices connect to a command-and-control (C&C) server, allowing the botmaster to issue instructions.
  3. Assignment: Bots are tasked with specific activities like sending spam or launching DDoS attacks.
  4. Execution: Bots operate collectively to maximize the impact of their tasks.
  5. Reporting: Bots send updates back to the C&C server about their activities and outcomes.

These steps allow cybercriminals to exploit botnets for coordinated and anonymous attacks, making them a significant threat to individuals and organizations alike.

Signs of a Compromised Device

Recognizing a compromised device is crucial. Look out for the following warning signs:

  • Lagging or overheating when the device is not in use.
  • Unexpected spikes in internet usage.

XorBot Evolves with Advanced Evasion Strategies, Targets IoT

 


A resurgence of the XorBot botnet was detected by NSFOCUS, which has been identified as a powerful threat to Internet of Things (IoT) devices across the world. XorBot was first discovered in late 2023; since then, it has evolved significantly, gaining advanced anti-detection mechanisms as well as a wider array of exploits and methods from which to sneak past detection. 

Cybersecurity defenders are now faced with a new challenge, especially in light of the latest version, version 1.04. The XorBot has consistently proven its ability to adapt and evade detection since it was first introduced in 2009. "XorBot is unequivocally one of the biggest threats to the security of the Internet of Things (IoT)," NSFOCUS reports. 

It targets devices such as Intelbras cameras and routers from TP-Link and D-Link, as well as a variety of other internet-connected devices. There are currently up to 12 exploit methods available in the botnet, and it has evolved to control a significant number of devices over the years. XorBot is particularly known for propagating its infection by exploiting vulnerabilities in IoT devices to spread. It has been confirmed by Thawte that one of the threat actor groups Matrix, has been linked to a widespread distributed denial-of-service (DDoS) campaign which exploits devices which are connected to the Internet of Things (IoT) due to vulnerabilities or misconfiguration. 

The devices involved in this operation, including IP cameras, routers and telecom equipment, have been co-opted into a botnet for purposes of launching disruptive attacks against a network. It appears that the campaign is primarily targeting IP addresses related to China and Japan, with a lesser degree of activity present in other regions including Argentina, Brazil, and the United States. Interestingly, Ukraine has not been targeted. This suggests that the campaign is being launched for financial reasons, not for political reasons. 

As part of the matrix attack, Matrix exploits known vulnerabilities in internet-connected devices by making use of publicly available tools and scripts, including those found on platforms such as GitHub. A variety of internet-connected devices, such as IP cameras, DVRs, routers, and telecommunication equipment, are vulnerable to attacks via attack chains using known security flaws and default or weak credentials, allowing adversaries to access a wide variety of internet-connected devices. 

Besides misconfigured Telnet, SSH, and Hadoop servers, it has also been observed that this threat actor is targeting IP addresses that belong to cloud service provider (CSP) IP address ranges such as Amazon Web Services (AWS) and Microsoft Azure, as well as Google Cloud Platform and rival cloud services just to name a few. As part of the malicious activity, a large number of publicly available scripts and tools are used, which is ultimately used to deploy the Mirai botnet malware and other DDoS-related programs on compromised devices and servers, as well. 

PYbot, Pynet, DiscordGo, Homo Network, and a JavaScript program that implements a flood attack using HTTP/HTTPS, as well as a tool that enables the disabling of Microsoft Defender Antivirus running on Windows machines are all included in the toolkit. Moreover, this botnet monopolizes resources in infected devices, leading to the /tmp directory being set as a read-only directory, making it impossible for any other malware to compromise the same device. 

The operators of XorBot have taken a new focus on profitability. They openly advertise distributed denial of service (DDoS) attacks as a service, advertising themselves as the Masjesu Botnet, an alias for XorBot. According to NSFOCUS, Telegram has become a central platform for recruiting customers and promoting services, as well as providing an excellent foundation for further botnet growth and expansion. This botnet, whose activity is aimed at evading detection by using advanced evasion techniques, poses a significant threat to cybersecurity efforts, as it utilizes advanced evasion techniques. 

As part of the anti-tracking design, it uses passive online methods to connect with control servers without sending identifiers such as IP addresses, thereby preventing an automated tracking system from being set up, such as how it will wait for instructions and respond with random data to obscure the tracking attempt. In addition to that, this attack uses "code obfuscation" to further impede detection through the embedding of redundant code and the concealment of its signatures, preventing static analysis from being performed. 

In addition, XorBot implements a unique communication mechanism that minimizes its visibility over the network, thus making it more stealthy. It is evident from these sophisticated tactics that the botnet has evolved rapidly and that it faces a growing number of threats that are related to the Internet of Things. The NSFOCUS report estimates that botnet operators invest heavily in anti-detection and anti-tracking techniques, making it significantly more difficult for defence mechanisms to counter.
