What is CrossRAT?

CrossRAT is a Trojan that was found spreading via malicious links that are sent randomly via email, Facebook, WhatsApp, and other social networking platforms. The link should be supported by a misleading message to make you think that nothing bad will happen if you click it. Unfortunately, many bad things can happen if you let the Trojan in because it enables attackers to access your operating system remotely. The worst part about it all is that this infection is very clandestine, and it is unlikely that you will realize that it is active right away. Needless to say, the longer this infection is active, the more trouble you are likely to get in. Our research team at has tested the threat and has devised instructions that show how to delete it. If you are still unsure if you even need to remove CrossRAT from your operating system, quickly install and run a legitimate malware scanner. You should take this step even if you have already unveiled the Trojan because you want to check if any other malicious threats are active.

How does CrossRAT work?

The main task for the malicious CrossRAT is to enable remote access to the corrupted computer. The attacker behind this malicious Trojan – and it appears that it is a group called “Dark Caracal” – can use this access to perform in a highly intrusive and malicious manner. For example, they could drop and run malicious files or even delete files that are found on your operating system. This privilege would allow them to eliminate security software-related files, as well as to run other malicious files capable of performing in unpredictable ways. Remote access Trojans are also often used for the collection of data. Once in, CrossRAT could silently record your keyboard input, track your mouse movements, or even capture screenshots. Unfortunately, all of this could be used to reveal login information and hijack your personal accounts. If cyber criminals steal your virtual identity, they can successfully expose users connected to you to scams and malware. This could be used to spread the Trojan itself to grow its network. Overall, it is unknown how exactly this malware could work, but it is known that, at the moment, it connects to to receive commands.

It does not matter whether you operate on Windows, Solaris, Linux, or macOS because the malicious CrossRAT can adapt to any of these major operating systems. The threat is written in Java, and so if the user does not have Java installed, it will not work. However, if it gains access to your system, it installs as mediamgrs.jar to the %TEMP% directory. A key for this file is created in the Windows Registry as well. You can find it at HKCU\Software\Microsoft\Windows\CurrentVersion\Run. If you do not notice these components, it is unlikely that you would notice the Trojan itself. This proves just how important it is to install reliable security software to guard your operating system at all times. If legitimate anti-malware software is not installed, malware can slither in and stay active without your notice.
