What is RSAUtil Ransomware?
RSAUtil Ransomware is a severe threat that can be responsible for rendering most of your files unusable. Once this beast manages to infiltrate your system, it can initiate the attack behind your back and encrypt your photos, videos, documents, archives, and even your .exe files to take them hostage. The main idea behind it is obviously extorting money from you for the decryption of your files. When it comes to ransomware infections it is important to understand that even if you have a backup copy of your most important files on a removable drive, it has to be always unplugged when not in use. Such a ransomware program can attack all mapped drives and unmapped network shares as well. So, if your removable drive is connected, you could lose all your files on it to this malicious attack. Also, some ransomware infections are capable of logging into your cloud storage account and destroy your files there. Although you are offered a way out of this vicious threat by paying a ransom fee to these criminals, we suggest that you do not consider it as an option. There is a good chance that these crooks would send more infections onto your computer disguised as a decryption tool or key. We recommend that you remove RSAUtil Ransomware immediately so that you can start recovering your files if you have a backup.
Where does RSAUtil Ransomware come from?
When your computer has been infected with ransomware, usually it is quite likely that you opened a spam mail previously and downloaded the attached file. This attachment generally can be an image, a video, or a document. However, in certain cases like this one it can also be a .zip archive carrying a number of malicious files related to the attack. So why would you click on this mail and save its attachment at all? The main reason behind this is that such a spam can make you feel like it contains important information, such as an unpaid invoice, a problematic online purchase with the wrong credit card details, and the like. Being more cautious around your mails could save you from most ransomware programs; however, not this one since RSAUtil Ransomware uses a different method to infiltrate your computer.
Some ransomware programs can also be spread by using malicious webpages created with Exploit Kits that can drop an infection without your knowledge the moment this page is loaded in your browser. In order for you to be able to avert such an attack, you should keep all your browsers and drivers updated. Nevertheless, even this would not save you from this particular infection because it uses yet another distribution method called Remote Desktop Protocol or RDP attack.
In this attack these criminals gain access to your computer or server somehow via a remote desktop program. This could be preceded by a phishing attack or social engineering to figure out your password. Although this could also be done by using brute force attack when all possible combinations are run in a trial-and-error way. It is very difficult to protect yourself and your computer from such an attack unless you use strong passwords. Once criminals gain access this way, they can easily disarm your security software if you have one at all. So when you have remote desktop software on board, you need to be very careful how it is configured and that it is protected by hard-to-crack passwords. Because when you finally delete RSAUtil Ransomware, it would just remove this malware infection but would not recover your encrypted files.
How does RSAUtil Ransomware work?
This is a Delphi-based malicious program similarly to Amnesia Ransomware and a few others. As we have already explained, this attack has to be initiated manually by the penetrator, i.e., the cyber criminal behind this malicious threat. First, a .zip file is dropped onto your system that contains all the necessary files related to this ransomware. The folder where these files are unzipped to contain the following files: config.cfg, DontSleep_x64.exe, How_return_files.txt, image.jpg, libeay32.dll, msvcr90.dll, NE SPAT.bat, svchosts.exe, and æ«ídG¿n_«t¿ßG¿G8.cmd. With the help of these files, the attacker can set up the environment for the ransomware to run smoothly. For example, the command file (.cmd) makes sure that all event logs that can be found on your computer are deleted so that the fact can be hidden that undesirable events have taken place. Then, this infection makes sure that the connection via RDP is kept alive by running DontSleep_x64.exe. The config (.cfg) file is used during the encryption process itself and carries vital information. Once everything is set up, the attacker runs the svchosts.exe file, which is the ransomware itself, and the encryption starts up.
Since this malicious program does not seem to have a file extension list to target, not even your .exe files are safe from this attack, which makes it even harder to stop and remove RSAUtil Ransomware. The encrypted files are easy to spot because they have a new extension: ".helppme@india.com.ID83994902." The ID part of this extension, or more precisely, the number code could different for all victims as this is the ID given by the ransomware, which can also be found in the ransom note. Speaking of which, this malware infection also places a text file named "How_return_files.txt" in every folder where files have been affected. Although the malicious .zip archive contains an image file that has some ransom note-like message on it, somehow this image is not used. Instead, a lock screen comes up with the very same information that you can find in the text files.
This note is written in broken English and asks you to contact these criminals via "helppme@india.com" or "hepl1112@aol.com" e-mail addresses, which also seem to be misspelled; however, this looks like it was done purposefully. You are to send your -- possibly -- unique ID that you can find at the top of the lock screen. In a reply message, you are supposed to get further details regarding the amount of the fee and the Bitcoin wallet address. We do not advise you to transfer any money to these criminals because you could lose more than your files. We recommend that you act immediately and remove RSAUtil Ransomware from your system.
How do I delete RSAUtil Ransomware?
