Have you recently scanned your operating system, and a threat called Crimson RAT (or CrimsonRat Trojan) has been found on your operating system? If it has, you might be in trouble because this RAT – which is short for “remote administration tool” – is a serious threat. Your virtual security could be put on a line if this malicious RAT was running wild on your operating system. The biggest problem is that users do not always understand what is going on because remote administrations tools can be very silent. This is why it is so important that users protect their operating systems and frequently scan them to check if any unwanted programs and threats have slithered in. Obviously, if malware is found, it must be removed immediately. Also, if you find that you need to delete Crimson RAT, there are things that must be done to ensure that your virtual security is strengthened. If you want to learn all about this, please keep reading.

Based on the research gathered by our malware researchers, Crimson RAT has been available for use since 2012. Remote administration tools are generally used to access to operating systems remotely. Legitimate RATs are generally used to solve technical and system issues that users cannot solve themselves. Malicious RATs exist as well, and they are controlled by cyber criminals who need to access an operating system to initiate malicious activity. While Crimson RAT might have been created with good intentions on the minds of its developers, it is publicly available, and anyone can use it to do whatever they want. The distribution of the malicious versions of this RAT is very unpredictable. Some parties could present them to users as something else. They could also be silently bundled along with more attractive pieces of software. Schemers behind bogus tech scams could also push users to install RATs so that they could allegedly assist them with the removal of malware. However this malware is installed, it can be used in various malicious ways.

Once schemers and cyber criminals gain access to the operating system, they can do all kinds of things. For example, they can download and execute malicious files. If that happens, malicious activities could be initiated even when you remove Crimson RAT. There is also a possibility that this malware could log keystrokes and mouse clicks, as well as capture screens to record information. Unfortunately, this could lead to the recording of login data and other sensitive information. If you have a microphone or a webcam connected to your operating system, they could be hijacked to spy on you as well. In fact, it is impossible to say how exactly the version of Crimson RAT installed on your PC is acting because every party using it can set it up to do different things. That is why removing this malware can be extremely difficult; especially if users decide that they want to get rid of this devious and clandestine malware manually.

Can you kill processes and delete malicious files? If you can, hopefully, you can identify malicious components as well because that is what you need to be able to do if you want to remove Crimson RAT manually all by yourself. Although manual removal is an option, our research team strongly recommends employing automated anti-malware software instead. Why? Because it can automatically erase all malicious files and programs, and since the RAT might have been used to download other malicious files, this is something you need to think about. Also, you need to think about security in the future, and anti-malware software can take care of that. However you delete the malicious RAT, you need to take care of your virtual security. For example, you should change the passwords of all sensitive account in case they were stolen by schemers.
