Remove DataCloud Ransomware

DataCloud ransomware is a crypto-virus that pretends to encrypt computer user’s files. Unlike the majority of ransomware, DataCloud archives the data into one large file and moves it to a cloud storage. This attack intends to deny user’s access to their data and DataCloud ransomware makers takes this opportunity to demand a ransom payment. In order for victims to restore the files back to their original state, they should follow the instructions from the ransom note dropped by this virus.

There are several ways that attackers are using to deploy DataCloud ransomware. Among the top distribution channels are malicious email attachment, cracked software, web injector, aggressive advertisements, botnet, and Trojan Droppers. As soon as DataCloud ransomware is executed on the computer, it looks for target files that are common to users like MS Office and Open Office documents, images, photos, videos, music, and similar files. As mentioned, DataCloud virus will process an imaginary encryption but in reality, files are archived and stored on an unknown location. Then, it generates a ransom note called README!!!!!!.txt, which informs user of the current attack. It also contains information on the full recovery of DataCloud infected files where in victims needs to contact the attackers by sending email message to data_cloud2012@aol.com. Here is the content of the ransom note.

Good time of day.
All your data has been moved to the cloud.
All of your information has two use cases.

Recover Files from DataCloud Ransomware Infection

On this section, we will provide ways to decrypt files infected with DataCloud ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting DataCloud infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by DataCloud ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of DataCloud virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by DataCloud virus, please follow these steps:

1. Open My Computer or Windows Explorer.

2. Right-click on the affected files or folders. From the drop-down list, please click on Restore previous versions.

3. New window will open display all backup copy of files and folders you wanted to recover. Choose the appropriate file and click on Open, Copy, or Restore. Restoring selected files overwrites the current locked files on the computer. The tool is not actually recovering files encrypted by DataCloud. Instead, it restores files from backup copy.

Option 2: Use ShadowExplorer to restore files encrypted by DataCloud Ransomware

Just like Previous Version tool, ShadowExplorer is taking advantage of shadow copy created by Windows. This tool allows you to retrieve older version of files before it was encrypted by DataCloud ransomware.

1. Download ShadowExplorer from the official web site.

2. Install the program with the default settings.

3. The program should run automatically after installation. If not, double-click on ShadowExplorer icon.

4. You can see the drop-down list on top of the console. Please select proper drive and the most recent point-in-time shadow copies of files you wish to restore prior to DataCloud ransomware infection.

5. Right-click on the Drive, Folder, or File you wish to restore and click Export...

6. Lastly, ShadowExplorer will prompt for location where you want to save the copy of recovered files.

How to protect the computer from DataCloud ransomware?

After the removal of the ransomware, it is important to prevent similar incident from happening again. In order to protect the computer effectively, computer user must know how DataCloud ransomware was able to infect the computer. To minimize the possible infection, staying away from the common sources of this virus is crucial.

How DataCloud ransomware can infect your computer?

The method of infecting the computers was found to be similar as other common viruses. Though, ransomware like DataCloud is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and through another virus infection.

Once the virus is executed, it immediately infects the system. Then, DataCloud ransomware communicates to remote server so that unique key can be generated for the specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. On the last stage of the attack, DataCloud ransomware demands for ransom money as payment for the decryption tool. To further understand the attack scheme, we have included an infographic below.
