This article has been made to show how to remove Hermes 2.0 ransomware virus and restore files encrypted by this infection on your PC.

A new variant of HERMES ransomware has been detected out in the wild. The virus aims to encrypt the files on the systems infected by it, after which drops a ransom note, which is named “DECRYPT_INFORMATION.html” and “DECRYPT_INFO.txt”. The virus also generates unique decryption keys based on which files can be decrypted when the ransom is paid. In case you have become a victim of this ransomware infection we advise reading the following material.

HERMES 2.0 Ransomware – Distribution Methods

The HERMES ransomware virus is reported by malware analysts to be spread via malicious e-mail spam messages. These messages may contain:

A malicious web link or a web link leading to the download of the infection file.
The infection file embedded as an attachment(document with malicious macros, executable, JavaScript file or other malicious executables).

Other methods by which HERMES 2.0 infection can occur are via the usage of malicious exploit kits, updates as well as infected installers, repackaged files and fake key generators or software activators. Such can be uploaded on torrent websites as well as websites that are risky. Such can be opened automatically by having a potentially unwanted program, causing redirections(https://sensorstechforum.com/remove-wowstart-online-redirect/) on your web browser.

HERMES File Virus – Infection Activity

When the user opens the infection file of the ransomware virus, it may connect to a remote host and drop the following files on the infected machine:

Reload.exe
system_.bat
shade.bat
DECRYPT_INFO.txt
DECRYPT_INFORMATION.html
UNIQUE_ID_DO_NOT_REMOVE
hermes.exe
shade.vbs

In addition to those files, the virus may also drop the following objects:

Cversions.2.db
Computer Management.lnk
Multiple .db objects with random names, located in %Caches% directory.

Once an infection has happened, HERMES 2.0 ransomware may immediately begin to use the method Evelen to bypass the UAC service. Then, the virus may execute the following commands without the user noticing with the purpose to delete shadow copies:

→ 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 of shadow copies, includes erasing files with the following file types:

→ .VHD .bac .bak .wbcat .bkf ,backup, .set, .win .dsk

After the virus has deleted the shadow copies, it may begin modifications in the Windows Registry Editor. These modifications may include attacking the run and run once windows keys with the following data:

→ 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

After the Reload.exe file has been ran, the ransomware virus begins the encryption process.

HERMES Encryption Process

The encryption process of HERMES 2.0 ransomware targets a lot of different file types to be encoded. The file extensions which are encrypted if detected by this ransomware virus are reported by malware researchers to be the following:

For the encryption process, this iteration of HERMES ransomware uses the file extension of it’s name and adds it without a separated, dot. Files appear like the following:

The encryption by HERMES 2.0 is performed with the assistance of two of the most sophisticated ciphers so far, the AES and RSA algorithms. The encryption process includes the encryption of the files via the AES cipher and then the RSA cipher appends an extra key to the files, unique for every infection.

After this has been completed, the private decryption information Is sent to the cyber-criminals and the second version leaves the following ransom note asking to contact the cyber-crooks via Bitmessage address:

Remove HERMES 2.0 Virus + File Recovery
