Random6 Ransomware – Distribution Methods

Since Random6 was detected to attack both companies and individual victims, the virus may be spread in more than one methods. One of those methods is reported to be via e-mail spam messages that carry malicious e-mail attachments in them. Such e-mails often pose as legitimate e-mails and their newest form includes carrying malicious Microsoft Word documents which infect your computer as soon as you click on the “Enable Content” button which triggers macros.

Other methods by which an infection with Random6 can take place is if the malicious files are downloaded via a fake web link posing as a legitimate button in the spam e-mail being sent, for example, the malicious spam below:

In addition to this, Random6 malicious files can also be uploaded online on torrent sites or suspicious software-providing sites. The virus may pretend to be a fake installer, fraudulent program activator or other key generators or license makers.

Random6 – More Information

As soon as it has infected your computer, Random6 ransomware aims to drop malicious files on multiple different Windows locations. The files may be under different, often random names, for example:

PIC

After the files are dropped on the computer the Random6 virus may create registry entries in the Run and RunOnce keys for the malicious file that is responsible for the file encryption process. These sub-keys of the Windows Registry Editor are located in the following places:

→ 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

In addition to this activity, the Random6 ransomware virus also aims to perform other activities on the compromised computer among which may be the deletion of all the shadow volume copies as well as backups on the infected computer. This is achievable in Command Prompt via the bcedit and vssadmin commands when the virus runs them as an administrator without the user noticing:

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

Among the malicious activities of Random6 ransomware is to drop it’s ransom note, named “RESTORE-{random 6 characters}-FILES.txt”. It has the following message for the victims of this virus:

“Your files are Encrypted!
For decryption send letter on email filesrestore@tutanota.com in letter attach your Personal ID.
If email don’t works, register here: https://bitmsg.me,
send letter to BM-N8azNh9xNVf2$gvav8pc3Uc9CCXtXMu
With your Personal ID and email for contacts.
After you send payment to given BTC adress in answer, you will get your files restored.
Your Personal ID:”

Random6 – Encryption Process

After Random6 infects your computer and triggers the malicious file which is responsible for encryption, it immediately attacks your documents, photos, music, videos, archives and other types of files. Among the file extensions targeted by Random6 may be many, for example:

Remove Random6 Ransomware and Restore Your Files

After the Random6 ransomware has infected your computer, the first action you must perform is to extract the encrypted files away from your computer (backup).

Then you can continue removing the malicious objects which Random6 creates on your computer. One method to do this is to follow the removal instructions after this article. Since manual removal may prove to be tricky primarily because Random6 modifies multiple different types of objects in Windows which may be risky to remove, experts advise using a more automatic approach. A ransomware-specific anti-malware scanner is advisable to be used in order to get rid of the malicious objects and settings changed by Random6 ransomware on your computer and protect it in the future as well.

If you are looking for a method to restore your files after you have removed Random6 ransomware, we have several alternative suggestions for you in step “2. Restore files encrypted by Random6”.
