The main method which may be used to spread this ransomware infection is believed to be via e-mail spam messages. The .styver ransomware, discovered by the researcher Michael Gillespie* https://twitter.com/demonslay335/status/968489946964267008) may come as a result of opening a malicious e-mail attachment which might as well be sent from companies, like:

PayPal.
DHL.
FedEx.
Amazon.
eBay.

The e-mail messages themselves may be created in a deceitful manner, pretending that the attachment is an important document of some sort, from the likes of:

An invoice.
An order receipt.
Banking statement.

In addition to this, there may also be another means via which the .styver files virus may infiltrate a computer system and this is if the virus file that causes the infection pretends as if it is:

Setup or a program.
Key generator.
License activator.
Crackfix.
Patch.

.styver Files Virus – More Information

Once infected a certain computer system, the .styver files virus may begin to drop it’s payload on the computer of the victim. The payload consists of the HELP ME PLS.txt ransom note, which has the following contents:

Hello. If you want to restore files, write me to styver.goodman@aol.com.

In addition to this, the .styver ransomware may also check if it’s running on a virtual drive or actual machine and close itself if it’s running in a virtual environment. The malicious payoad files of the virus may be more than one and are likely in the following Windows folders:

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

After the .styver ransomware infection has dropped it’s payload on the victim’s computer, the malware may also add registry entries in the Run or RunOnce Windows registry sub-keys in order to make it’s executables and ransom note run automatically on system login. The sub-keys have the following locations:

→ 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 .styver ransomware has set it’s registry sub-keys to run on the computers of victims, the malware may begin to encrypt the files on the compromised computers and also may delete the shadow volume copies to eliminate any chances of restoring them via system backup. The commands to do this 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.
Archives.
Pictures.
Music.

The .styver ransomware may then encrypt those files on your PC, adding the .styver file suffix. After the encryption process is complete, the files can no longer be opened and contain the .styver file extension added after their name, looking like the following:
