What is UltraCrypter Ransomware?
Apparently, UltraCrypter Ransomware is the newest version of a Trojan infection called CryptXXX Ransomware. The malware encrypts user’s personal data just like the old variant. This time, the ones who created the infection demand a ransom of approximately 500 US dollars. If you do not wish to put up with these demands, you can eliminate the malware with the removal instructions available below. Furthermore, our specialists at Anti-spyware-101.com informs us that the ransomware could settle in your system with a help of a malicious tool called Angler Exploit Kit. At this point, you should worry not only about your encrypted data but also about the fact that your system is vulnerable to malware. In this situation, it is advisable to install a legitimate antimalware tool and scan your system.
How does UltraCrypter Ransomware work?
Firstly, UltraCrypter Ransomware creates a CLSID folder with a .dll file in the %TEMP% directory. Both the file and folder should have random names. Then, the malware modifies a legitimate system file known as rundll32.exe, copies it in the same CLSID directory and uses it to run the .dll file.
The encryption process might not start right away. The research revealed that the ransomware might wait from 15 to 60 minutes before it begins the encryption. Afterward, UltraCrypter Ransomware should place .txt, .bmp, and .html documents titled as “decrypt-instructions”. The text inside explains that all personal data was encrypted with a strong cryptosystem, and if you want to unlock it, you have to pay 1.2 Bitcoins. The ransomware’s creators give you some time to make the payment, but threaten to double it if you do not transfer the money. The most important thing is to stay calm because panic can lead you to a rash decision that you might regret later. These cyber criminals may not bother to send you the decryption key. Therefore, if you put up with their demands, you may lose not only your data but also a rather huge amount of money.
Where does UltraCrypter Ransomware come from?
UltraCrypter Ransomware might be dropped on your system by a malicious application called Angler Exploit Kit, which attacks your system while exploiting its security flaws. This indicates that your computer is left unprotected, and it is vulnerable to malware. Perhaps, you do have a fully updated antimalware tool, or you do not update other software. What is left to do now is to erase the malware and find a way to guard your system.
How to delete UltraCrypter Ransomware?
Some variants of UltraCrypter Ransomware could lock your screen to prevent you from deleting the malware. Our researchers noticed that you may be able to unlock your screen if you press Ctrl+Alt+Del and restart your computer. Then you can follow the instructions provided below and erase the ransomware manually. It might be difficult to locate the malicious .dll file because it could be placed in a CLSID folder that has a random name. However, our specialists noticed that some versions of the malware do not create CLSID folders, but rather place the .dll file in the Temporary files directory, so you should check this location too. If you do not think you can erase the ransomware on your own; install a legitimate antimalware tool and leave this job to it.
