Cybersecurity experts are raising alarms about the Murdoc Botnet Mirai Variant, a new and dangerous malware strain targeting Internet of Things (IoT) devices.
Leveraging known vulnerabilities in Avtech cameras and Huawei routers, this variant has rapidly grown into a global threat. According to a recent Qualys report, the botnet has been active for over six months, exploiting these vulnerabilities to recruit thousands of devices into its network.
With over 1,300 IPs implicated and 100 command-and-control (C&C) servers identified, this malware showcases the critical need for vigilance and timely security updates.
What Is the Murdoc Botnet Mirai Variant?
The Murdoc Botnet Mirai Variant is an evolution of the infamous Mirai malware designed to exploit specific security flaws in IoT devices. Once compromised, these devices are enlisted into a botnet — a network of infected devices used to execute cyberattacks such as distributed denial-of-service (DDoS) campaigns, data theft, and more.
The Murdoc variant specifically targets vulnerabilities in Avtech cameras and Huawei routers, making it a focused but highly effective threat.
Since its discovery, researchers have identified over 300 unique malware samples, indicating the botnet’s rapid adaptation and growth. The ability to quickly exploit unpatched devices underscores the importance of timely security updates.
Vulnerabilities Targeted by the Murdoc Botnet
1. Avtech Cameras (CVE-2024-7029)
- Vulnerability: The botnet exploits a critical remote code execution (RCE) vulnerability in Avtech AVM1203 IP cameras.
- Discovery Date: The U.S. Cybersecurity and Infrastructure Security Agency (CISA) identified this flaw in August 2024.
- Impact: Approximately 38,000 internet-facing devices are vulnerable, allowing attackers to take full control of these cameras.
- Manufacturer Response: Avtech has yet to release a patch, leaving many devices exposed to attacks.
2. Huawei Routers (CVE-2017-17215)
- Vulnerability: The malware leverages an older RCE vulnerability found in Huawei HG532 routers.
- Discovery Date: This issue was first reported in 2017, yet many devices remain unpatched.
- Impact: Unprotected routers provide an easy entry point for attackers, enabling the botnet to spread rapidly.
Global Impact of the Murdoc Botnet
The Murdoc Botnet Mirai Variant has infected devices worldwide, with a particularly high concentration in regions heavily reliant on IoT technology. Countries like Malaysia, Thailand, Mexico, and Indonesia are among the most affected.
| Country | Number of Infections |
|---|---|
| Malaysia | High |
| Thailand | Moderate |
| Mexico | Moderate |
| Indonesia | Moderate |
These infections disrupt essential services and compromise sensitive data, making it a significant concern for both individuals and businesses.
Why Is the Murdoc Botnet Dangerous?
The Murdoc Botnet’s ability to exploit unpatched devices and recruit them for malicious purposes poses several risks:
- DDoS Attacks: The botnet can launch large-scale attacks to overwhelm and disrupt services.
- Data Breaches: Compromised devices can expose sensitive user information.
- Operational Disruption: Businesses relying on IoT devices may face operational downtime.
- Economic Loss: Attacks can result in financial losses from downtime, repairs, and stolen data.
Real-Life Impact of Mirai-Based Malware
The original Mirai botnet was behind one of the largest DDoS attacks in history, targeting Dyn, a DNS provider, in 2016. This attack disrupted major websites, including Twitter, Netflix, and Reddit.
The Murdoc variant, though more focused on its targets, has the potential to cause similar damage.
Protecting Against the Murdoc Botnet Mirai Variant
To safeguard your IoT devices from this threat, follow these recommendations:
- Update Device Firmware: Regularly check for and install updates from your device manufacturer.
- Monitor Network Activity: Look for unusual traffic patterns that may indicate a compromised device.
- Change Default Passwords: Use strong, unique passwords for each device.
- Limit Remote Access: Disable unnecessary remote access features.
- Enable Firewalls and Security Tools: Protect your network with robust firewall settings and antivirus software.
How the Murdoc Botnet Operates
Murdoc employs a sophisticated network of over 100 C&C servers to communicate with compromised devices and distribute malware. Once a device is infected, the botnet:
- Deploys Payloads: It installs ELF and shell script files that enable the malware to run seamlessly on the compromised device.
- Launches DDoS Attacks: Like its Mirai predecessors, Murdoc conducts powerful DDoS attacks to disrupt targeted services.
- Spreads Further: The botnet continues to exploit vulnerabilities in other devices to expand its reach.
A Real-Life Example
In a similar attack in 2016, the original Mirai botnet disrupted internet access across the U.S., targeting DNS provider Dyn and causing outages for major websites like Twitter and Netflix.
