Malware Attack Hits 3CX Desktop App: IT Professionals Take Notice

The malicious world of hackers and cybercriminals is constantly evolving, and it can be difficult for IT professionals to keep up with the latest security information. However, an attack on the 3CX desktop app that was discovered by malware hunters recently has highlighted the importance of staying aware and vigilant.

What is 3CX?

3CX is a unified communications platform used by businesses and organizations to enhance their internal and external communication systems. The 3CX app for Windows allows for the installation of various plugins that add extra features to their core system.

What happened?

Malware hunters recently discovered a malicious file in the official catalogue of the 3CX desktop app. This file, when installed, would add malicious scripts to users’ machines. These scripts would cause the affected machines to phish information from the users and send it to a remote server. The attack appears to have been a supply chain attack, as the malicious file was found in the official catalogue and not injected into the system by hackers.

What can be done?

The fact that this attack was a supply chain attack means that IT professionals need to prioritize security at all levels. By doing so, they can ensure that any malicious code that is included in the system can be quickly identified and eliminated. Additionally, IT professionals should always keep an eye out for any suspicious activity, as well as any updates or changes in the system.

IT professionals should also be aware of the security of any third-party plugins that are installed on the system. These plugins may also be vulnerable to malicious attacks, and steps need to be taken to ensure that they remain secure.

The development team at 3CX have been quick to respond to this attack, and have already released a patch that should fix the issue. It is important for IT professionals to ensure that their systems are up to date and are running the latest version of this patch.


Malware attacks are becoming increasingly sophisticated and difficult to detect, and this attack on the 3CX Desktop App is a reminder of the importance of staying vigilant. IT professionals should always be aware of the security of their systems and take steps to ensure they remain secure. The development team at 3CX have acted quickly to issue a patch to fix this issue, and IT professionals should ensure that their systems are running the latest version.
