The world of cybersecurity is always changing at a breakneck speed. Every day, new and more sophisticated attacks emerge. Despite the fact that most of these threats have been patched, some of them are still crawling around the internet. One such example is LemonDuck.
It’s a cross-platform virus that infects Windows and Linux computers and serves as a gateway for other malicious software. So, what is LemonDuck, exactly? What is the mechanism behind it?
What Is LemonDuck Malware?
LemonDuck is a powerful malware that targets Windows, Linux, and edge devices such as WiFi routers. It has been active since 2019 and is still infecting devices for various reasons.
LemonDuck steals credit card information, disables security rules, and installs tools for hands-on keyboard attacks, in addition to standard mining activities.
The malware’s name comes from the variable “Lemon Duck,” which appears in most of the malware’s scripts. During botnet connections, this variable is typically used to set up the user-agent.
How Does LemonDuck Infect IT Infrastructure?
LemonDuck is distinguished from other mining malware by its ability to withstand security patches. It spreads through phishing emails, USB drives, and older but still active exploits, among other methods. Furthermore, once LemonDuck has infected a system, it patches the same vulnerability it used to gain access.
It’s also begun to employ advanced command and control (C2) centers, as well as increased lateral movement. One of the most notable characteristics of the LemonDuck malware is its ability to run intelligent and successful campaigns. It gains access by compromising edge devices or infecting email accounts with bots.
Once inside, LemonDuck looks for open or weak SMB, SQL, RDP, Hadoop, or Exchange networks on the Linux or Windows host. It then tries to take advantage of them in order to spread to other devices.
How to Protect Your Windows or Linux Device From LemonDuck
It’s difficult to stay safe from sophisticated botnets. To gain access, LemonDuck exploits a number of old flaws. So make sure you’re up to date on your security patches to keep yourself safe from exploits that are readily available.
Because LemonDuck is spread through phishing emails, you should scan any email attachments for malware before or as soon as you download them.
Well, that’s all we have for you about the LemonDuck malware. We hope this guide helps you stay safe from malware.
