New Mirai Botnet Exploits Industrial Router Zero-Day

New Mirai-Based Botnet Exploits Vulnerabilities in Industrial Routers and Smart Home Devices

A new and sophisticated Mirai-based botnet is exploiting over 20 vulnerabilities in industrial routers and smart home devices, including the recently uncovered Four-Faith router bug (CVE-2024-12856). This alarming development has raised concerns among organizations globally, particularly in countries like China, the U.S., Germany, the UK, and Singapore. According to a report from BleepingComputer, these attacks facilitate distributed denial-of-service (DDoS) operations that generate massive traffic spikes, even though each attack lasts only 10 to 30 seconds.

Understanding the Mirai Botnet and Its Impact

The latest analysis from Chiainxin X Lab researchers highlights the botnet’s advanced capabilities. Here are some key insights into its operations:

• Vulnerabilities Exploited: The botnet takes advantage of widely known flaws in various devices, including DVRs and PZT cameras, making it a significant threat to both home users and industrial sectors.
• Attack Methodology: It employs a brute-forcing module and a modified UPX shell, utilizing Mirai-based commands for various functions such as client updates and network scanning.
• Compromise Rates: The botnet’s ability to leverage zero-day and n-day vulnerabilities allows for escalated compromise rates, creating further risks for affected organizations.

Recommended Security Measures

Organizations must take proactive steps to protect their devices from these DDoS attacks. Here are some recommended security measures:

1. Update Devices Regularly: Ensure that all devices are running the latest firmware to patch known vulnerabilities.
2. Change Default Credentials: Replace any default administrative passwords with strong, unique credentials.
3. Limit Remote Access: Disable unnecessary remote access features to minimize potential attack vectors.
