Remove REDROMAN Ransomware (Virus Removal)

REDROMAN ransomware is another crypto-virus that was designed to specifically lock the majority of computer files and deny user’s access to it. This virus will apply a complex algorithm technique to ensure that files remains unusable and convince computer users to obtain the decryption software in order to restore the entire .REDROMAN files back to their original format. Due to the applied advanced technique of encryption, it would be impossible to recover the files without the proper decryption tool. This is why attackers are taking advantage of this situation to extort money from their victims.

How REDROMAN Virus Infiltrates the Computer?

There are many ways for malware authors to introduce REDROMAN ransomware and because of the global connection via the internet, they can easily accomplish this task. Web injectors, malicious file installers, social engineering attacks, spam email campaign, Trojan Downloader, and exploiting the RDP (remote desktop protocols) are just some of the ways and means for widespread of REDROMAN ransomware.

With the mentioned channels of deployment, it was observed that the majority of ransomware victims have obtained the virus via phishing email campaign. REDROMAN ransomware is normally embedded as an attachment to legitimate email and purporting as a valid document file. Once opened or viewed, REDROMAN ransomware starts the first phase of its attack.
Malicious software installer comes as second widely used method to deploy REDROMAN ransomware. This executable file instantly launches the infection during the setup procedure and computer users will never experience any signs of the infiltration.

Attackers have two ways to deliver the goods. It is either directly load REDROMAN ransomware or inject a Trojan dropper on the computer that will later leverage to a ransomware infection. The latter found to be a better option because this petty virus can conceal itself better once inside the computer. Therefore, it can perform various malicious actions without being detected by security applications.

REDROMAN Ransomware File Encryption

Upon the successful penetration of the virus, it makes a connection to remote command-and-control server to fetch addition malware. The server was made also to deliver the public key to the infected computer and once obtained, REDROMAN ransomware will start the encryption process. The virus applies the key during the complex encryption method. In addition, all encrypted data will get appended with .REDROMAN file extension.

Like in the mainstream of ransomware attack as TG33, Slgh, Lockbit, and many more, REDROMAN ransomware is is going to inform computer users through a generated ransom note. It contains brief description as well as method to recover the encrypted files. As usual, victims has to pay the ransom demand before they can acquire the decryption software.

Recover Files from REDROMAN Ransomware Infection

On this section, we will provide ways to decrypt files infected with REDROMAN ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting REDROMAN infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by REDROMAN ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of REDROMAN virus.

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by REDROMAN virus, please follow these steps:

1. Open My Computer or Windows Explorer.

2. Right-click on the affected files or folders. From the drop-down list, please click on Restore previous versions.

3. New window will open display all backup copy of files and folders you wanted to recover. Choose the appropriate file and click on Open, Copy, or Restore. Restoring selected files overwrites the current locked files on the computer. The tool is not actually recovering files encrypted by REDROMAN. Instead, it restores files from backup copy.
