Advanced VPN Troubleshooting On MikroTik Devices
As more and more people are becoming captivated by the world of cryptocurrency, cyber criminals have found new and insidious ways to take advantage of the trend. One recent example of this is a form of malware that has infected over 200,000 Mikrotik routers, creating a network of compromised devices that can be used to carry out a range of nefarious activities.
So what exactly is this malware, and how does it work? Here's what you need to know:
1. The Malware is Called Coinhive
The malware that has been found on the compromised Mikrotik routers is known as Coinhive. It is a type of cryptocurrency mining malware that is designed to surreptitiously use the computing power of the infected device to carry out cryptocurrency mining – in this case, mining the privacy-focused Monero cryptocurrency.
2. Coinhive was Initially Used Legitimately
Interestingly, Coinhive was originally a legitimate tool that was used by various websites as a way to monetize traffic. The idea was to use the CPU power of visitors to mine Monero in the background, providing a source of income for website owners. However, it didn't take long for cyber criminals to realize the potential of this tool, and they soon began using it for their own purposes.
3. The Malware Affects Mikrotik Routers
The Coinhive malware was found on over 200,000 infected Mikrotik routers, which were mainly located in Brazil. These routers are widely used in homes and businesses across the world, and many people are unaware that they have been compromised. The malware is capable of persisting despite rebooting, and can be used to carry out a range of attacks and data exfiltration via the compromised routers.
4. The Malware Uses Multiple Exploits
The Coinhive malware uses a range of exploits to compromise Mikrotik routers. These include known vulnerabilities in the router's software, as well as brute-force attacks on the router's login credentials. Once the malware gains access to the router, it installs various components that allow it to carry out its mining activities and other attacks.
5. The Malware can be Difficult to Detect
One of the most insidious aspects of the Coinhive malware is that it can be difficult to detect. Because it runs in the background and doesn't typically cause any noticeable increase in system resources, it can go unnoticed for long periods of time. In many cases, people may not even realize that their router has been compromised until they start experiencing other problems, such as slow internet speeds or difficulty accessing certain websites.
6. The Malware can be Difficult to Remove
Removing the Coinhive malware from a compromised Mikrotik router can be a difficult and time-consuming process. In many cases, simply resetting the router to its default settings is not enough, as the malware is able to persist despite rebooting. Instead, it may be necessary to manually remove various files and components, or even to completely reflash the router's firmware.
7. Prevention is the Best Defense
As with many forms of cyber attack, prevention is the best defense when it comes to the Coinhive malware. There are a number of steps that you can take to minimize the risk of infection:
- Keep your router's firmware updated to the latest version
- Use strong, unique passwords for your router's login credentials
- Disable remote access to your router if you don't need it
- Use a reputable antivirus program to protect your devices
By taking these steps, you can help to minimize the risk of becoming a victim of the Coinhive malware – or any other form of cyber attack that may be targeting your devices and network.
The Bottom Line
The Coinhive malware that has infected over 200,000 Mikrotik routers is just one example of the growing trend toward cryptocurrency mining malware. As the popularity of cryptocurrencies continues to rise, it is likely that we will see more and more such attacks in the future. By taking steps to protect your devices and network, you can help to ensure that you won't become a victim of these insidious and difficult-to-detect threats.
