Remove UmbreCrypt Ransomware

UmbreCrypt Ransomware is another crypto virus. UmbreCrypt Ransomware targets PCs running Windows OS. It requires from the victims to send an e-mail for instructions on how to decrypt their files. Every file that has been encrypted will have its extension changed to .umbrecrypt_ID_[victim_id].

When running, UmbreCrypt Ransomware will start creating executables in the Temp folder. Then, it will start encrypting files stored on local or mounted network drives using a AES-256 bit public-key cryptography, with the private key stored only on the control servers.

UmbreCrypt Ransomware will create README_DECRYPT_UMBRE_ID_[victim_id].txt. The file contain instructions explaining how to pay the ransom. Your wallper will also be changed to README_DECRYPT_UMBRE_ID_[8 random characters].jpg. When UmbreCrypt Ransomware is initiated on the computer, it will inject deep into the system infecting Explorer.exe and svchost.exe, modify the registry to start with Windows, and disable the Automatic Repair feature. Once active, it will start the processes of encrypting files. These types of ransomware are very hard to detect. Nevertheless, the virus will show its presence after the encryption finishes.

The instructions will show the victims how to send their ID to umbredecrypt@engineer.com or umbrehelp@consultant.com in order to get their files back Such software could lead to more malware coming into your computer and even cause a loss of data. Such threats are not to be underestimated!

How to Recover Files Encrypted by UmbreCrypt Ransomware:

You can try to recover your files from a system backup. If there is no backup available, one can try to restore the files using the Shadow Copy Service. Windows XP Service Pack 2 and future versions have an integrated feature called Shadow Copy Service which will automatically create backup copies of your files. This method is not bullet-proof, as HydraCrypt Ransomware may delete the shadow copies.

Method 1. Using Windows Previous Version tab:

*The Windows System Protection service must`ve been enabled before the infection, otherwise it will not work.

  1. Right-click on the encrypted file, select Properties from the menu.
  2. Click on “Previous Version” tab (If missing, this means that Windows System Protection has not been enabled).
  3. Choose a previous version copy and click on the Copy button. Select a directory you wish to recover the file to, or you can try to restore the selected file, directly, by hitting the Restore button.

The method could be used to recover an entire folder. Just right-click on the highlighted folder and select Properties, and then Previous Version tab.

Method 2. Using Shadow Explorer:

Using Shadow Explorer to restore whole folders. You can download the program from the link below:

2. Once you`ve downloaded it, you would have to locate any encrypted files on your system and also where you had an original unencrypted version. If you are not able to find both files, you would need to locate an encrypted PNG file and then download any random PNG image from the internet. Hilight both files, and then drag and drop them onto the DecryptHydraCrypt.exe.

5. Accept the license agreement.

6. Click the “Decrypt” button to start the decryption. If you have other drives or folders that you wish to add for decryption, you can add them by clicking on the Add folder button.
