UltraCrypter Ransomware Removal Guide

Do you know what UltraCrypter Ransomware is?

Recently, our malware researchers went on a hunt for malware and, lo and behold, they found a ransomware-type program called UltraCrypter Ransomware. Removing this infection is highly recommended because it is programmed to encrypt your personal files and ask you to pay a ransom of more than $500 USD. When it encrypts the files, it is already too late, and you cannot do anything about it. There is no alternative method to decrypt the files without having to pay the ransom because this program uses one of them most secure encryption algorithms currently available. However, the problem is that this infection’s developers might not give you the decryption key after you have paid.

Our malware researchers have found that this ransomware is distributed using the Angler exploit kit that can silently enter your computer from malicious websites. This exploit kit can get on your computer if you use an outdated version of Java or Adobe Flash, so you need to have them updated all of the time. This exploit kit is buried deep into a given website, and you will not notice if the infection takes place. This method is widely used by ransomware developers as these kits can drop files without alarming the anti-virus program. Therefore, you should have an anti-malware program that can complement the anti-virus program because these two types of programs are not one and the same. We recommend using SpyHunter as it has a large database that can prevent your computer from becoming infected with the likes of UltraCrypter Ransomware.UltraCrypter Ransomware Removal GuideUltraCrypter Ransomware screenshot

However, if this ransomware manages to get on your computer, then you will be looking at a lot of trouble because it is set to encrypt particular file types that contain personal information. Our malware analysts say that ransomware can encrypt approximately one hundred file types, such as .rofl, .hkx, .bar, .upk, .das, .sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, and so on. However, it will not touch system files as they are necessary for your computer to run so that you could pay the ransom.

Even the most low-grade ransomware these days uses advanced encryption algorithms to encrypt the files of their victims so that they would no change of getting them back without paying. However, UltraCrypter Ransomware uses the RSA-2048 encryption cipher that turns files into a useless pile of bytes, and it is impossible to decrypt them using some other means. In the past, some ransomware encryptions were cracked, and malware analysts have developed decryption tools, but, at least for now, this particular ransomware does not have such a tool. UltraCrypter Ransomware’s developers ask you to pay 1.2 BTC (Bitcoins) which are $567.6 USD. However, if you do not pay within the given time limit, then the ransom can increase to $1008 USD.

When a computer becomes infected with this ransomware, the Angler exploit kit drops a file named msxml6r.dll to %TEMP%. Interestingly, this particular infection is not run directly using an executable file. The msxml6r.dll file is executed using the rundll32.exe file that is copied to the %TEMP% folder from %WINDIR%\SysWOW64 or %WINDIR%\System32. Furthermore, this infection can rename rundll32.exe to svchost.exe. Once the files have been dropped and the encryption completed, the ransomware will create apparently randomly named .bmp, .html, and .txt files in %ALLUSERSPROFILE% and on the desktop, but the file names contain a unique user ID that is used to identify your computer. The .txt file contains information on how to pay the ransom while the .bmp file is set to replace your desktop’s wallpaper to make it clear on what has happened to your PC. The .html file redirects to one of this ransomware’s websites.

If you want to remove this infection without paying the ransomware, then you can use our removal guide composed by our malware researchers. However, due to the fact that its files are named randomly, it can be difficult to identify them. If that is the case, then use our recommended anti-malware tool. Note that after deleting UltraCrypter Ransomware you will be unable to restore the encrypted files.

Removal instructions

  1. Simultaneously press Windows+E keys.
  2. Enter C:\Users\User\AppData\Local\Temp\{randomly named CLSID} in the address box.
  3. Find msxml6r.dll (name may vary) and delete it.
  4. Then, C:\ProgramData and delete the randomly named .bmp, .html, and .txt files.
  5. Lastly, delete the .bmp, .html, and .txt files from the desktop.
  6. Empty the Recycle Bin.

In non-techie terms:

UltraCrypter Ransomware is a nasty infection that can enter your computer using a particular exploit that makes use of malicious websites. This exploit is configured to secretly drop this ransomware’s files to your computer. Then, it encrypts your files and makes them inaccessible. This infection wants you to pay money for the decryption key which you may or may not receive. If you want to remove it, then use our removal guide or SpyHunter, our recommended anti-malware program.
