The rise of the “Gayfemboy” Botnet: A New Mirai-Based threat Targeting IoT Devices
Table of Contents
In the ever-evolving landscape of cybersecurity, the Mirai botnet has become a household name—or perhaps more accurately, a nightmare. Known for its ability too hijack Internet of Things (IoT) devices like routers, cameras, and smart home gadgets, Mirai has been a persistent threat since its emergence in 2016.Now, a new variant, dubbed the “gayfemboy” botnet, has emerged, leveraging zero-day exploits and refined tactics to wreak havoc on industrial and consumer devices alike.
What Is the Gayfemboy Botnet?
Discovered by Chinese cybersecurity firm Qi’anxin XLab in Febuary 2024,the gayfemboy botnet is a Mirai-based threat that has evolved far beyond its predecessors. Initially, it appeared as just another iteration of the infamous malware. Though, its developers have as incorporated n-day and zero-day vulnerabilities to expand its reach and effectiveness.
This botnet targets a wide range of devices, including Four-Faith industrial routers (exploiting CVE-2024-12856) and Neterbit routers, as well as Vimar smart home devices. According to XLab, the botnet exploits over 20 vulnerabilities and weak Telnet passwords to spread, with around 15,000 active IPs observed across China, Russia, the US, Iran, and Turkey.
Key Features of the Gayfemboy Botnet
- Zero-Day Exploits: Leverages previously unknown vulnerabilities in industrial and smart home devices.
- DDoS Attacks: Launches distributed denial-of-service attacks, targeting hundreds of victims daily.
- Global Reach: Active IPs span multiple countries, with significant activity in China, the US, and Europe.
How the Gayfemboy Botnet Operates
The botnet’s operators have demonstrated a high level of sophistication. After XLab registered some command-and-control (C2) domain names to analyze the botnet,the attackers retaliated with relentless DDoS attacks.
“We resolved the registered domain name to our cloud vendor’s VPS. after discovering this, the owner began to regularly launch DDoS attacks on our registered domain name, with each attack lasting 10 to 30 seconds,” XLab said.
the attacks were so severe that the cloud vendor repeatedly blackholed XLab’s VPS traffic, rendering it inaccessible for over 24 hours at a time. “Once the VPS service was restored, it attacked again,” the researchers noted.
This cat-and-mouse game highlights the botnet’s resilience and the challenges faced by cybersecurity professionals in combating such threats.
the Broader Threat of Mirai-Based Botnets
The gayfemboy botnet is just the latest example of how Mirai malware continues to evolve. Originally designed to target IoT devices,Mirai has become a blueprint for cybercriminals seeking to exploit the growing number of connected devices worldwide.
As CIS explains,Mirai turns networked devices running Linux into remotely controlled bots,which can then be used in large-scale network attacks.This makes it a potent tool for launching DDoS attacks, disrupting services, and causing widespread chaos.
Why IoT Devices Are Vulnerable
IoT devices are often designed with convenience in mind, not security. Manny lack robust authentication mechanisms,leaving them susceptible to brute-force attacks and exploitation. As How-To geek points out, devices like routers, IP cameras, and even thermostats are prime targets for botnets like mirai.
Protecting your Devices from Mirai-Based Threats
While the gayfemboy botnet poses a significant threat, there are steps you can take to protect your devices:
- Update Firmware Regularly: Ensure your devices are running the latest firmware to patch known vulnerabilities.
- Change Default Passwords: Replace weak or default passwords with strong, unique alternatives.
- Disable Telnet: If not needed, disable Telnet access to reduce the attack surface.
- Use a DDoS Mitigation Service: Protect your network with a reliable DDoS mitigation solution.

The Rise of the “Gayfemboy” Botnet: A New Threat to IoT Security
The world of cybersecurity is constantly evolving, with new threats emerging at an alarming rate. One such threat is the “Gayfemboy” botnet, a Mirai-based malware that has been infecting a wide range of internet-connected devices. This interview with Dr.emily Carter, a leading cybersecurity expert, sheds light on this emerging danger and what we can do to protect ourselves.
What is the “Gayfemboy” Botnet?
Senior Editor: Dr. carter, can you explain what the “Gayfemboy” botnet is and why it’s causing concern?
Dr. Emily Carter: The “Gayfemboy” botnet is a new variant of the notorious Mirai malware. Mirai has been around for a while, known for hijacking internet-connected devices like routers, cameras, and smart home gadgets to launch powerful DDoS attacks. What makes “Gayfemboy” particularly worrying is its use of zero-day exploits – vulnerabilities that are unknown to device manufacturers. This allows it to infect devices that haven’t been patched with the latest security updates.
How Does It Work?
Senior Editor: How does the ”Gayfemboy” botnet spread and what kind of damage can it cause?
Dr. Emily Carter: It primarily spreads through these zero-day exploits and by scanning for devices with weak passwords. Once infected, a device becomes part of the botnet, effectively controlled by the attackers.They can then use this army of compromised devices to launch DDoS attacks, overwhelming websites and online services with traffic, rendering them inaccessible. Imagine a hospital’s website being taken down, preventing patients from accessing crucial information – that’s the kind of havoc a botnet like this can wreak.
Targets and Impact
Senior Editor: Who are the primary targets of the “Gayfemboy” botnet?
Dr. Emily Carter: This botnet has shown a particular interest in industrial routers – devices that control critical infrastructure. Think power grids, transportation systems – these are incredibly vulnerable. It also targets smart home devices. This is particularly concerning because it not only disrupts our daily lives but also raises privacy concerns. Hackers could perhaps spy on us through compromised cameras or smart speakers.
Staying Safe
Senior Editor: What can individuals and businesses do to protect themselves from this threat?
Dr. Emily Carter: There are several steps we can take:
Strong Passwords: Use unique and complex passwords for all your devices.
Software Updates: Keep your devices updated with the latest security patches. Manufacturers often release updates to fix vulnerabilities.
Network Segmentation: Separate your critical devices from your less-secure ones. This can help contain a breach.
Use a Firewall: A firewall acts like a barrier between your devices and the outside world, blocking unauthorized access.
* Be Aware: Educate yourself on the latest cyber threats and stay informed about potential vulnerabilities.
senior Editor: Dr. Carter, thank you for sharing your valuable insights. This is a wake-up call for us all to take cybersecurity seriously.
