.corrupt Ransomware – Spreading Methods

In order to get this ransomware out there and running, the cyber-criminals have though the process through. They may have utilized an exploit kit which uses vulnerabilities in unpatched Windows systems to enter undetected and drop the malicious files of the ransomware via an intermediary infection file or a malicious web link. These objects are often seen as fake e-mail attachments, like the one in the malicious e-mail that is carefully disguised below:

After the victim opens the malicious file, the infection process is triggered and the malicious file drops the payload of the virus on the victim's computer. Usually, the file may be obfuscated itself in order to avoid conventional antivirus programs from detecting it. This process ensures a more successful infection to take place.

In addition to via e-mail, the ransomware may infect users via multiple different types of files that may pose as legitimate ones, for instance:

Software setups.
License activators.
Game patches and game cracks.
Fake torrent files.

.corrupt Ransomware Virus – Activity

Once the payload of the .corrupt files virus is dropped, it may consist of more than one malicious files and these files may reside in the following commonly targeted Windows directories:

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

After having dropped it's malicious files, the .corrupt files virus may perform other activities on the computer of the victims, like interfere with the following Run and RunOnce Windows registry sub-keys by adding registry value strings with data in them:

→ 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

This allows for the .corrupt files virus to run it's malicious files automatically when Windows starts up. If you check the data of those registry entries, which are usually value strings with random names, the actual file encrypting executable's location can be discovered.

In addition to this, the .corrupt files virus also obtains permissions to run administrative commands via the Windows Command Prompt. Some of the commands which the virus may run on your computer may be hidden from your sight and delete your backups, shadow volume copies plus disable the Windows Recovery service. The commands are usually ran via a script and are the following:

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

Documents.
Videos.
Music files.
Archives.
Virtual drive files (.vdmk, etc.).

The encryption process may be performed by using the AES or RSA encryption algorithms (or both in combination) via different encryption modes, like RC4 for example. This is done with the purpose of increasing the difficulty to decipher the decryption key which is generated after the process is complete.
