.pr0tect File Virus – Infection Methods

The Pr0tector ransomware is no different than any other threat out there. The virus uses different malicious loaders which cause the infection by running obfuscated scripts which latter connect to the c2 servers of the cyber-criminals. These intermediary infection files are usually used in multiple different ways to deceive you into opening them:

  • In spam e-mails that are focused on tricking users with deceptive messages to open them as attachments.
  • As fake setups of programs posted on suspicious websites.
  • As files that pose as game cracks or program patches on torrent websites.
  • As fake updates.
  • Via other malware that may have already infected your computer.

Via potentially unwanted programs that may in some scenarios cause an infection by causing browser redirects or different types of third-party malvertising, which if clicked on executes a script.

.pr0tect File Ransomware – Infection Activity

After the infection happens, the malicious files of this ransomware infection are dropped on the infected computer, and they may reside in the following Windows folders:

  • %AppData%
  • %Roaming%
  • %Local%
  • %LocalRow%
  • %Common%

After the files are dropped, multiple processes of the compromised machine may be used to make sure that several settings on it are modified. One of those may be the deletion of shadow volume copies by executing a set of 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

The virus may also create String Values with custom data which leads to the location of the malicious executables of this ransomware infection. These executables may be set to run on startup. The same may be done to change the wallpaper on the infected computer. The usually targeted registry keys that may be used by the .pr0tect file virus are the following:

→ HKEY_CURRENT_USER\Control Panel\Desktop\
HKEY_USERS\.DEFAULT\Control Panel\Desktop\
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 this has happened, the .pr0tect virus may cause an error message to appear on the compromised computer and then either perform the encryption directly or force restart the machine and do the encryption process on system boot.
