.army Virus Files

One of the most popular communication forms – e-mail is one of the most common methods used by hackers who distribute ransomware infections like Army virus. Usually, criminals tend to disguise the infection file as some sort of an important document – an invoice, a receipt or another important file. The e-mails may appear as if they are sent by banks or big companies, like PayPal, eBay, etc. Their look is often very similar to the one of the legitimate ones.

The Army ransomware may also be spread via compromised websites, torrent sites or websites with low security reputation. There, the file may pose as something you may be looking to download, like:

  • A program’s installer.
  • A crack for a program or a game.
  • Key generator to obtain a license.
  • Some type of license activator.
  • Portable version of a program you want to use.

When the Army virus infects your computer, it may situate malicious files in the following Windows directories:

  • %AppData%
  • %Local%
  • %Roaming%
  • %LocalLow%
  • %Temp%

The malicious files are accompanied by the ransom note of the Army virus which is named HOW TO DECRYPT FILES.txt. It informs the following:

Attention! All your files are encrypted!
To restore your files and access them,
please pay

You have 5 attempts to enter the code.
When that number has been exceeded,
all the data irreversibly is destroyed.
Be careful when you enter the code!

Malicious files may be set to perform unwanted activities like modifying the Run and RunOnce Windows registry sub-keys. By adding entries in them, the threat can start executing the encryption module automatically every time you switch on the infected machine. The targeted sub-keys are usually:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

For the Army virus to encrypt target files, it may execute various different types of programs that perform a scan of the files. After the scan detects a target file, the threat runs a cipher module to encode the original code of the detected file. The files that may be encrypted include:

  • Documents.
  • Video file types.
  • Image formats.
  • Photoshop files.
  • Database files.
  • Audio file types.
  • Archives.
  • Other popular file types.

After this ransomware encrypts the files on the infected machines by it, they immediately assume the .army file extension and begin to appear like the following:
