Distribution of .gocr File Virus

The threat payload may be distributed via several ways. As preferred one are considered to be spam emails with malicious attachments or compromised links. Such emails usually impersonate well-known business organizations or even governmental institutions aiming to mislead the receiver and make him quite willing to act according to the text message. The email attachment may be documented with embedded malicious macros that contain the ransomware payload. When the document is opened, the user is asked to enable macros. If he does, an executable file triggers the ransomware infection. The links may be destined to mirrored web pages of popular websites. Usually corrupted web pages are designed to download and start the ransomware payload on the computer automatically. Other methods of distribution are fake software notifications, fake setups of free programs, and malicious adverts.

Overview of .gocr Virus Attack

Once the malicious .gocr ransomware payload is running on the system, the attack begins. The .gocr file virus also known as DCry ransomware performs a sequence of malicious activities starting with downloading additional malware files that support the successful infection. These files may be situated in Windows directories like:

  • %AppData%
  • %Temp%
  • %Roaming%
  • %Common%
  • %UserProfile%
  • %System32%

After all malicious files are obtained the ransomware can execute various functionalities. One of the most common actions carried out by crypto viruses like .gocr is shadow volume copies wipe. By acquiring administrator privileges, the threat can execute the following command in Windows Command Prompt:

→ vssadmin.exe delete shadows /all /quiet

This will delete all backed up files on the computer called shadow volume copies and prevent one of the possible ways for .gocr files recovery. In addition .gocr file virus is believed to create registry entries within 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

Those keys are targeted as they are behind all automatically executed processes on every Windows start up. When .gocr file virus adds its malicious values, it is able to load each time the user starts the PC. The ransomware uses the functionalities of Run and RunOnce keys to display its ransom note at the end of the attack. The message is stored in a text file with the name HOW_TO_GET_MY_FILES.txt. Once it is opened the victim can see the following text:

Hello my friend, first sorry for this.
Your files have been crypted with the AES-256 method.
Don’t try decrypt files use third-party software, otherwise you may loss all files permanently.
If you want to decrypt your data, write to e-mail: [email protected]
If you want to test the decrypt, go to https://s7c4wrcmzgbtldbs.onion (use tor browser)

Your ID: STGO_[redacted base64]

It is advisable to restrict any negotiations with cyber criminals. Even though they are likely to promise victims that after ransom payment all .gocr files will be decrypted, there is no guarantee that they will keep the promise. For the sake of your security, we recommend following the step-by-step instructions to remove .gocr file virus and restore corrupted data.
