Power_user_jo – What We Know About It

Power_user_jo is a cryptovirus that is pretty standard. Other infections, like it include
Divsouth virus and Motion ransomware. Just like these two viruses, the Power_user_jo ransomware can also infect your computer if it is being sent to you as an e-mail attachment. Such attachments often pretend to be legitimate types of documents that the user is pushed to open. Examples can be an important document from your bank, plane ticket, fake order invoice, etc.

Another way via which the Power_user_jo can infect your computer is by being downloaded and ran on your computer as a program of some sort. Usually, viruses like Power_user_jo are uploaded on sites with low reputation and pretend to be:

  • Portable programs.
  • Patches.
  • Crack for software or game.
  • Fake installers of apps.
  • Updates.

Once your computer gets infected with this ransomware, it may connect to a command and control server, operated by the criminals behind it. From there they may know all sorts of information from your computer, like Windows version, IP and Mac addresses and other details. Then, the virus may download and place its files in the following Windows directories:

  • %LocalLow%.>
  • %Temp%.
  • %ProgramData%.
  • %Windows%.
  • %AppData%
  • %System%.
  • %system32%.
  • %Roaming%.
  • %Local%

Once the files are set-up on your machine, the Power_user_jo ransomware may begin encrypting your data. It may start scanning for the following types of files:

  • Images.
  • Videos.
  • Documents.
  • Audio files.
  • Archives.

As soon as the files are detected, the Power_user_jo virus may encrypt them using an advanced encryption algorithm. The main purpose of doing this is to make sure the files cannot be opened, but can still be unlocked if you have a specific decryption key. These decryption keys are known by the cyber-criminals who infected your computer with this ransomware.

After the virus finishes the encryption process, it leaves its ransom note file, called Data recovery.hta. It has the following text:

power-user-joe ransom note

_RSA Encrypted Files

The files, encrypted by this virus have the _RSA suffix at the end of them. This points out to strong encryption being used, known as RSA cipher (Rivest-Shamir-Adleman). This cipher encrypts parts of files and generates unique keys per each file. After this the keys are sent to the criminals.

For this specific virus, the files are also renamed with a unique number and letter code, that also leaves the files looking like this:

rsa-key

Removal of the virus is highly advisable and we do not recommend negotiating with or trusting these criminals.
