.dcrtr files virus – How Does It Infect

The primary methods of infection that are being used to propagate this ransomware are both passive and active methods. If passive, the cyber-criminals are more lazy and may upload the files on torrent websites or suspicious software sites with high ranking in order to “fish” for potential victims. The files are carefully masked as:

  • The drivers or the setup of programs you may be looking to download.
  • Fake software license activators.
  • Fake game or program patches.
  • Fake cracks or key generators for software or games.

In addition to using this method, the cyber-criminals may also spread the virus actively by taking the job to manually send e-mails to a pre-configured lists of victims’ e-mail addresses. Such lists they usually purchase on the dark net, where organizations or hackers may steal personal information and sell it for their own profits. The e-mails which may be sent may contain your name, and they may pretend to come from reputable companies, from the likes of PayPal, eBay, FedEx or other big companies. They usually mask a malicious e-mail attachment which is then used as a legitimate document, for instance:

  • Invoice.
  • Activation code file.
  • Receipt for an order.
  • Banking information of importance.

Since the virus may also use malicious e-mail web links which may carry JavaScript code that may cause an automatic download and execution of files, it is also a possibility of infection with the .dcrtr ransomware virus. If we had to explain it with graphics, here is how the infection process would appear like as a chain of consequential activities:

.dcrtr Files Virus – Maliciious Activity

As soon as the .dcrtr files ransomware has infected the victim’s computer, the malware may perform series of unwanted activties on the victim’s computer, which may result in the virus receiving administrative privileges to read and write files on your computer. Then, the malware may connect to a C&C server from which the malicious files of .dcrtr ransomware may be dropped on the victim’s computer. They may reside in the following Windows directories:

  • %Local%
  • %LocalLow%
  • %AppData%
  • %System%
  • %system32%
  • %Temp%

In addition to this, the ransomware virus may also modify the following Windows registry sub-keys:

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

The .dcrtr files ransomware may create registry entries in those sub keys with data which points to the actual location of the malicious files which are being executed. This may result in the malware running automatically when you start Windows.

Furhtemore, the .dcrtr files ransomware may also perform other activities on the victim’s computer, such as delete the shadow volume copies and backups by executing a script that may run the following commands as an administrator in Windows Command Prompt without you even noticing it:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

After these commands are ran, the .dcrtr files virus may also perform other activities on the victim’s computer, such as set it’s ransom note, named ReadMe_Decryptor.txt to be automatically displayed and show the following message:

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail decryptor@cock.li
