JeepersCrypt Ransomware - How To Remove?

 

JeepersCrypt ransomware virus is categorized as a Portuguese malware since its screen-lock displays demands in this language. Let’s go straight to the pleasant part: JeepersCrypt variant was not created by professionals and its structure appeared to have been quite weak. As a consequence, it is now assigned to the group of ransomware infections that have already been solved. A universal tool for decryption, called StupidDecryptor, has been efficiently modified to detect and decipher files that have been affected by JeepersCrypt and got appended with .jeepers extension. It is possible that Perseus Trojan is involved in the distribution of this malware as this is suggested by results that security tools inform victims about.

Description of JeepersCrypt ransomware

JeepersCrypt crypto-virus gives a limited amount of time to make a transaction of bitcoins. In 24 hours, the sum of 0.02 BTC is expected to be transferred to hackers.

A letter called ‘I want to buy a key to decrypt my files’ is supposed to reach hackers. Since individual victims won’t receive different ID numbers, it is presumably that ransomware uses static keys which will act as universal decryption codes for all infected people. For this reason, it was relatively uncomplicated to solve this sample. We should also mention that JeepersCrypt ransomware does not appear to be extremely greedy as its ransom is only 24.95 US dollars. However, since this sample is easily decryptable, there is no reason to abide by the rules that hackers insist on.

Despite the fact that JeepersCrypt ransomware is not a sophisticated virus, it is still a threat. People might act irrationally and make transactions of bitcoins if they do not search for more information on the Internet. Since this malware blocks access to the computer and displays a ransom note instead, people can be eager to send 25 US dollars and get it over with. Before encryption with ciphers can be successfully executed, it is important that the virus would modify Windows Registry Keys. Entries will be altered so the JeepersCrypt.exe payload would join the list of software applications that get automatically launched after a computer device is rebooted.

Step 3. Restore JeepersCrypt ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Jeeperscrypt virus tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.

Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.

a) Native Windows Previous Versions

Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:

  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download Data Recovery Pro (commercial)
  • Install and scan for recently deleted files. Data Recovery Pro

Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
