Type: Ransomware
 

Diamond Computer Encryption ransomware virus is a unique infection despite functioning on a similar level as the preceding infections we have discussed. Exactly like ABCLocker or KillSwitch malware samples, the new variant is based on Hidden Tear open source project. Without any surprise, such copycats of HiddenTear usually direct an AES cipher to encode executables that are located in ‘\test’ directory. After this crypto-virus encodes all files, it inserts _READ_IT_FOR_RECOVER_FILES.html file which loads up in users’ preferred browser.

Diamond Computer Encryption malware is a severe threat

The domain that gets loaded will display a picture of a diamond, allowing people to select a specific language in case they do not understand the language set by default: English. For translation, Google Translate will be exploited; therefore, there might be some inconsistencies with the texts, adjusted to people from other countries. Furthermore, this devastating virtual infection of Diamond Computer Encryption was crafted with .net framework, and it has a capacity of damaging VirtualBox guest entries.

Much to our concern, TeamViewer remote monitoring application is appended into terrorized operating systems, presumably Windows OSs. TeamViewer is exploited by thousands of people around the world; however, figures in charge of development and distribution of this software have investigated reports about ransomware infections, entering devices thanks to some sort of glitches in TeamViewer. Diamond Computer Encryption crypto-virus might not enter due to TeamViewer, but it could be exploited by hackers for the purpose of establishing remote connection.

A unique extension to all casualties of Diamond Computer Encryption crypto-virus: how to recover them?

Naturally, the encrypted data will be marked with randomly generated extensions, consisting of 6 digits: a template for it appears to be [a-z0-9]. This means that there is no specific extension that shall be applicable to all victims of this crypto-virus.

Step 3. Restore Diamond Computer Encryption ransomware virus 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 Diamond Computer Encryption ransomware 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.

Step 4. Use Data Recovery programs to recover Diamond Computer Encryption ransomware virus encrypted files

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.
