CSGO Ransomware – How Does It Infect

The main method of infection, used by the CSGO ransomware virus has been reported to likely be via e-mail spam messages. The virus aims to slither it’s infection file by possibly sending messages that have malicious attachments within them or malicious web links that cause the infection. This process may include the e-mails to pretend to be legitimate and to come from big companies from the likes of:

  • PayPal.
  • eBay.
  • Amazon.
  • AliExpress.
  • FedEx.
  • DHL.

The e-mails often pretend to have invoices or receipts in them to increase the likelihood of the victim clicking on them.

In addition to via e-mails, the CSGO Ransomware virus may also be spread as a result of the crooks having to upload the malicious file on torrent websites and other suspicious software providing sites. The file may pretend to be:

  • Setup of a program or game.
  • Software crack.
  • License activation patch.
  • Crack.
  • Key generator.

Victims often look to “patch” games and play them without paying for them and this is what some cyber-criminals consider an advantage, infecting wide range of users, by making the file seem legitimate.

CSGO Ransomware – Analysis

Once the CSGO ransomware infection has been downloaded on your computer, it’s malicious file extracts or downloads the payload of the virus on the victim’s computer. The payload consists of multiple files that may have the following locations:

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

After the payload of this ransomware virus has been downloaded onto the computer of the victim, it may be extracted and activated. This may result for the ransomware obtaining various different details about your computer, such as:

  • If CS:GO is installed on it.
  • If the virus is running on a virtual drive or a real computer.
  • Your IP address and unsecured ports.
  • Security software installed on your PC.

The CSGO ransomware then may set various different types of registry sub-keys on the computer of the user, whose purpose is to usually make it run automatically when you boot Windows. Such keys are likely the Run and RunOnce 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

After the ransomware has done this, it may then orient towards deleting the volume shadow copies on the user’s computer. This is conducted by running a malicious script that triggers Windows Command Prompt as an administrator. The commands which it runs may be the vssadmin and bcedit commands:

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