Crucial information about VO_ ransomware virus

The good news is that VO_ virus might not be as dangerous as Locky which recently rampaged on the social media [1]. Since only several versions of this malware have been detected, many speculations arise about the capabilities of the ransomware. Once this misfortune befalls your computer, all personal and important files get locked up. What is more, they might all bear .vo file extension. We recommend starting VO_ removal right away. As it is little known about the virus, delaying the process might cause even more severe outcomes. One of the practical tools to speed up the process is to install an anti-spyware program, such as Reimage.

Luckily, not all emerging file-encrypting viruses are as hazardous as ransomware titans, for instance, Cerber virus or CryptoLocker which keep inspiring hacker-wannabees. Speaking of VO_ malware, it follows the manner of encoding the data with AES algorithm. It has been mainly used by National Security Agency to encipher the secret documents. Unlike stream ciphering, the main feature of AES is to encode the data by running several repeated cycles of block encryption [2]. If ransomware states that it has employed a AES-128 code, it means that 128-bit key comprises the algorithm formula. Such encryption method proves to be effective in IT cyber security field as well as in a hacking world. Felons, shifting to this method, make extra guarantees that even if victims are computer literate, they would not decrypt files without their “assistance.” At least, they want you to think so. Considering such psychological terror techniques, you should not trust VO_ ransomware hackers as well. The absence of clear instructions of decoding the files leaves room for speculations that this malware might be just a beta version of a more developed virus appearing in the future. In any case, remove VO_ virus right away.

The dangers of VO_malware

When did my computer get infected with the ransomware?

Spam and phishing perform the role of a haven for a variety malware, including banking trojans, ransomware, and extortionware [3]. The latter also possesses the same features as ransomware, but it is more oriented at blackmailing victims [4]. Getting back to the topic of this article and specifically, VO_ hijack, note that it might cover under the disguise of fake delivery email. Gearheads are quite crafty in devising officially looking emails. The ransomware payload might even get delivered in the email which is supposedly sent from Amazon [5]. Likewise, check your system for any adware files as well. A while ago, the PUP under the same title hit the internet stage. It might be linked to the current ransomware.

If your files are encrypted by VO_, you can use several methods to restore them:

How practical is Data Encryption Pro?

If you haven’t backed up your data, and haven’t saved copies of your most important data elsewhere, then, this utility might be one of the last chances to restore the data.

Windows Previous Versions feature – alternative to restore your data?

This method might require more time as you have to go through each affected file and implement the following steps.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Shadow Explorer and its modus operandi

This is one of the more viable ways to retrieve the data in case you do not have a backup. In short, this utility recreates the files based on volume shadow copies stored on Windows. 

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from VO_ and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
