DarkLocker Ransomware – How Does It Spread
For this ransomware infection to actually reach computers of unsuspecting users, the creators of the virus have also engineered a plan to spread it. One scenario of spreading the ransomware is by conducting a massive spam campaign of e-mail messages sent to many users on a global scale. To do this, the cyber-criminals may have a pre-configured e-mail list of legitimate e-mail addresses. To obtain such lists, they may purchase it on the black market by someone who collects personal information by stealing it or breaking privacy policy of shady websites.
Then, these e-mails may be embedded in a spam bot which in it’s turn sends spam messages with malicious e-mail attachments, like the example below:
Once the attachment is opened, infection by DarkLocker is inevitable.
But this may not be the only way of infecting with this virus. The DarkLocker malware may spread via fake updates, programs, patches and other “software” uploaded online as well.
DarkLocker Ransomware – Activity
Once the user becomes infected, the virus may situate it’s malicious files on the following Windows folders of great importance:
- %AppData%
- %Roaming%
- %Local%
- %LocalRow%
- %SystemDrive%
- %Startup%
- %Windows%
Among the malicious files may be different types of exectuables as well as support modules, but the main two identified are named as the following:
- can.exe
- Winlk.exe
After this infection drops it’s files, it may initiate modifications by adding value strings with data in the Windows Registry Editor. The predominantly targeted Windows Registry keys are the following:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
In addition to this, the DarkLocker ransomware may also delete backups, system restore points and shadow volume copies of Windows. It may also shut down critical system security processes to ensure uninterrupted file encryption
DarkLocker Ransomware – Encryption Process
For the file encryption of this virus, one or more than one encryption modes can be used to render the files no longer openable. This is achievable by combining the encryption mode with the cipher. The DarkLocker virus may be pre-configured to encrypt only a portion of the files, hence the larger the file, the more size will be encrypted. This is done to ensure a faster encryption process. For the infection, DarkLocker may target certain files of bigger importance than the average file types. Such files may be:
- Documents.
- Images.
- Audio files.
- Videos.
- Database files.
- Other files associated with often used software.
In addition to performing this, the DarkLocker virus may also be careful to avoid encrypting files in different system folders, that may cause Windows to misbehave and even crash.
After the encryption process is compete. The ransomware has been reported by researcher Amigo A to display the following ransom note type of file, extorting victims to pay ransom:
