How to remove Root Ransomware and decrypt .root{number} files

What is Root Ransomware

Root Ransomware is a malicious software variant belonging to the MedusaLocker family, designed to encrypt files on a victim’s computer system, rendering them inaccessible. It modifies the filenames by appending a distinct extension in the format .root{number}, where the number can vary, signifying different iterations or versions of the ransomware. For example, an image file named 1.jpg would be renamed to 1.jpg.root4. The encryption process employs sophisticated algorithms, typically combining RSA and AES encryption methods, to secure the data so that it cannot be easily decrypted without a unique key. Victims discover the unwelcome encroachment on their data through a ransom note titled How_to_back_files.html, which is usually placed in every folder containing encrypted files. This note forewarns victims about the encryption of their files, discouraging them from attempting file recovery through third-party software, and threatens the public release of sensitive data if the ransom demands are not met.

Unfortunately, as of the current understanding and availability of cybersecurity tools, there are no known public decryption tools capable of reversing the encryption imposed by Root Ransomware without paying the ransom, assuming no critical flaws exist in the ransomware’s code. The absence of these tools highlights the importance of preventative measures such as maintaining regular data backups and employing robust security software. Decrypting files with the “.root{number}” extension without the key held by the cybercriminals is nearly impossible, emphasizing the risk associated with not having a comprehensive backup strategy. It is not advised to pay the ransom, as there’s no guarantee the attackers will deliver the decryption key, and it might further encourage malicious activities. For those affected, professional data recovery services or cyber-risk consultations might be their best bet in restoring access to vital data without falling into the trap of the perpetrators.

How Root Ransomware infects computers

Root Ransomware, a variant of the MedusaLocker family, infiltrates computers primarily through deceptive emails and malicious attachments or links, which lure unsuspecting users into clicking them. Often, these emails are crafted to appear legitimate, adding a layer of social engineering to trick the recipient. Apart from emails, this ransomware can spread via pirated software or compromised files downloaded from untrustworthy sources like unofficial websites or peer-to-peer networks. Vulnerabilities in outdated operating systems and software can also be exploited by attackers to deploy ransomware. Additionally, it may propagate through malicious advertisements, technical support scams, or infected USB drives, making it crucial for users to exercise caution and maintain robust security measures to prevent infection.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .root{number} files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with Root Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Root Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
