The malware has been outlined by experts to be spread with the assistance of spammed e-mail messages. Such messages may spread files or web links of the following infection characters:
- Malicious web link, which when clicked on downloads and executes the infection file.
- Web link which can cause an infection by simply being clicked on.
- The infection file directly uploaded as an e-mail attachment, masked as a legitimate invoice, receipt or other forms of documents.

In addition to this, there is also a chance that you may see the virus, masked as a fake installer of a program or an infected legitimate one which triggers the infection after you run the program or game. Other cases which have been reported also include using game patches, driver installers or fake license activators for software, uploaded on torrent sites with low ratings for security.
HERMES 2.1 Ransomware – Malicious Activity
After an infection with the HERMES 2.1 ransowmare threat takes place on your computer, the malware uses an unsecured port on your PC, via which it may silently drop the following malicious files directly on your PC:
→ Reload.exe
system_.bat
shade.bat
DECRYPT_INFO.txt
DECRYPT_INFORMATION.html
UNIQUE_ID_DO_NOT_REMOVE
hermes.exe
shade.vbs
The files of HERMES 2.1 may be dropped on system folders and Windows directories, the main of which may be the following:
→ %AppData%
%Local%
%LocalLow%
%Temp%
%Windows%
%System%
%System32%
After these payload files have been dropped and ran on the victim’s computer, they may also run automatically and create the following files on the victim’s computer:
→ Cversions.2.db
Computer Management.lnk
Multiple .db objects with random names, located in %Caches% directory.
As soon as this is done, the HERMES 2.1 virus may also use the Evelen method in order to bypass User Account Control (UAC) service. This may result in the malware being able to run Windows Command Prompt and execute the following commands in order to delete the shadow volume copies and disable file recovery services and all of this is usually done without the victim noticing this
→ 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 deletion process does not concern one backup method, since HERMES 2.1 is a bit more sophisticated than the traditional ransomware. The virus also attacks the following file formats, which represent backup copies:
→ .VHD .bac .bak .wbcat .bkf ,backup, .set, .win .dsk
As soon as all backup on your infected computer is gone, the malware may start to modify the registry editor of your computer. The modifications include adding value strings with data in them that allow the malware to run automatically when you boot your PC and also to open it’s ransom note automatically as well. The attacked registry sub-keys are as follows:
→ HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run” /v “allkeeper” /t REG_SZ /d “%USERPROFILE%\Desktop\DECRYPT_INFORMATION.html” /f
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run” /v “sysrep” /t REG_SZ /d “%PUBLIC%\Reload.exe” /f
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run” /v “allkeeper” /t REG_SZ /d
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run” /v “sysrep” /t REG_SZ /d
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\allkeeper C:\users\User\Desktop\DECRYPT_INFORMATION.html
The HERMES 2.1 ransomware also does not forget to add it’s ransom note file, which contains the following message to victims:
