The digital world is under siege once again as spinoffs of the notorious Mirai botnet have launched a global wave of distributed denial-of-service (DDoS) attacks. These campaigns are exploiting vulnerabilities in Internet of Things (IoT) devices, compromising them to propagate malware and orchestrate large-scale cyberattacks. With organizations across North America, Europe, and Asia feeling the brunt of these attacks, the cybersecurity landscape is facing a renewed challenge from an old adversary.

1. Mirai Botnet Spinoffs in Action: Two separate campaigns leveraging Mirai-based malware are targeting IoT devices globally. One, dubbed “Murdoc_Botnet,” exploits specific vulnerabilities in Avtech cameras and Huawei routers, while the other uses a combination of Mirai and Bashlite malware to compromise devices with weak credentials.
2. Murdoc Botnet Details: The Murdoc botnet uses known exploits like CVE-2024-7029 and CVE-2017-17215 to download payloads onto compromised devices. Over 1,300 active IPs are involved, with most located in Malaysia, Thailand, Mexico, and Indonesia.
3. Global DDoS Campaign: A second campaign, detected by Trend Micro, has been targeting organizations in Japan, the US, Bahrain, Poland, and Spain. The attacks focus on wireless routers and IP cameras from brands like TP-Link, Zyxel, and Hikvision.
4. Attack Vectors: The campaigns employ two types of DDoS attacksâone that floods networks with packets and another that exhausts server resources by establishing numerous sessions.
5. Defense Recommendations: Researchers recommend monitoring suspicious processes, using firewalls to block malicious traffic, and collaborating with service providers to filter DDoS attacks. For session-based attacks, limiting requests per IP and using third-party services are advised.
6. Ongoing Threat: Miraiâs legacy continues to pose a significant threat, with its variants evolving and adapting to exploit new vulnerabilities.
What Undercode Say:
The resurgence of Mirai-based botnets highlights the persistent vulnerabilities in IoT devices and the evolving nature of cyber threats. Despite being over a decade old, Miraiâs leaked source code has spawned countless variants, each more sophisticated than the last. This latest wave of attacks underscores the importance of proactive cybersecurity measures and the need for organizations to stay vigilant.
The IoT Security Crisis
The widespread adoption of IoT devices has introduced a new frontier for cyberattacks. Many of these devices lack robust security features, making them easy targets for botnets like Mirai. The Murdoc botnetâs exploitation of specific vulnerabilities in Avtech cameras and Huawei routers is a stark reminder of how outdated or unpatched systems can become gateways for large-scale attacks.
The Global Impact of DDoS Attacks
The global nature of these campaigns demonstrates the far-reaching consequences of DDoS attacks. From disrupting major corporations in Japan to targeting critical infrastructure in the US, the ripple effects of these attacks can be devastating. The combination of network overload and resource exhaustion tactics makes it even harder for organizations to defend against them.
The Role of Weak Credentials
One of the most alarming aspects of these campaigns is the use of weak passwords to compromise devices. Despite repeated warnings, many users and organizations continue to use default or easily guessable credentials, leaving their systems vulnerable to exploitation. This highlights the need for better education and enforcement of strong password policies.
Mitigation Strategies
The recommendations from Qualys and Trend Micro provide a roadmap for defending against these attacks. However, implementing these measures requires a concerted effort from organizations, service providers, and manufacturers. Regular monitoring, timely patching, and collaboration with cybersecurity experts are essential to staying ahead of these threats.
The Future of Mirai
As long as IoT devices remain vulnerable, Mirai and its variants will continue to evolve. The cybersecurity community must work together to address these vulnerabilities, whether through improved device security, stricter regulations, or more robust defense mechanisms. The battle against botnets is far from over, and the stakes have never been higher.
In conclusion, the latest wave of Mirai-based DDoS attacks serves as a wake-up call for the global cybersecurity community. By understanding the tactics used by these botnets and implementing effective defense strategies, organizations can better protect themselves from this ever-present threat. The fight against cybercrime is ongoing, and staying informed and prepared is the best defense.
