The '.Jupstb File Extension' Ransomware also interferes with the victim's ability to recover the compromised files in other ways, such as by deleting the Shadow Volume Copies of the affected files and the Windows System Restore points.

The '.Jupstb File Extension' Ransomware's Ransom Demand

The '.Jupstb File Extension' Ransomware demands a ransom from its victims to provide them with the means to revert the files' encryption. To do this, the '.Jupstb File Extension' Ransomware delivers a ransom note in the form of a text file named 'Readme_Restore_Files.txt,' which is dropped on the infected computer's desktop. This ransom note delivers the following message to the victim's computer:

'Attention!
Do not rename the ciphered files.
Do not try to decrypt your data with the help of the third-party software, it can cause constant data loss.
If you, your programmers or your friends help you to decrypt your files - it can lead to data loss.
You do not joke with files.

Security experts do not endorse that computer users contact the criminals responsible for the '.Jupstb File Extension' Ransomware attack. Typically, the victims that attempt to pay the ransom or establish contact with the criminals responsible for the '.Jupstb File Extension' Ransomware attack will either be ignored or targeted for additional malware attacks and tactics. Because of this, there is no real positive outcome of trying to negotiate with the criminals responsible for the '.Jupstb File Extension' Ransomware attack.

Dealing with the '.Jupstb File Extension' Ransomware Infection

The best way to deal with the '.Jupstb File Extension' Ransomware infection is to restore any files compromised by the '.Jupstb File Extension' Ransomware attack from file backups. This is why having file backups is the best protection against these attacks. Computer security researchers also recommend that computer users have an anti-malware program that is fully up-to-date.
