How to remove Gunra Ransomware and decrypt .ENCRT files

What is Gunra Ransomware

Gunra Ransomware is a type of malicious software designed to encrypt digital data and demand ransom payments for access restoration. This ransomware appends the file extension .ENCRT to each encrypted file, transforming filenames like document.docx to document.docx.ENCRT, thereby locking users out of their own data. It employs sophisticated encryption algorithms, making decryption without the necessary keys virtually impossible. Once the ransomware has completed the encryption process, it creates a note, the R3ADM3.txt, which is typically placed in affected directories and prominently displayed on the victim’s desktop. This ransom note explains the encryption situation, claims the theft of sensitive business data, and outlines the process of contacting the cybercriminals via the Tor network to potentially regain access to compromised files. Victims are often lured into contacting the attackers by the incentive of decrypting some files for free as proof of capabilities, along with a stern warning that delays or non-cooperation will lead to public data exposure.

Currently, there are no available decryption tools capable of reversing the encryption carried out by Gunra without access to the specific decryption key held by the attackers. Unfortunately, this key is kept securely on a remote server controlled by the hackers, beyond reach of typical data recovery means. Restoring .ENCRT files without directly dealing with the attackers is unlikely, emphasizing the crucial role of preventative measures. Experts advise against paying the ransom, as payment does not guarantee decryption and only emboldens cybercriminals. Instead, focus on removing the ransomware from the system to prevent further encryption. Whenever a ransomware attack occurs, prioritize identifying and isolating the infection to stop it from spreading further. Regularly updated backups, stored separately from the main system, remain the most reliable method of recovery as they allow users to restore their files to a pre-encryption state without succumbing to extortion demands.

How Gunra Ransomware infects computers

Gunra Ransomware infiltrates computers primarily through phishing and social engineering tactics. Cybercriminals often disguise malicious files as legitimate attachments or bundle them with seemingly harmless software, luring users into downloading and opening them. These infectious files can take various forms, such as ZIP archives, executable files, or documents containing malicious macros. Once executed, Gunra Ransomware can quickly encrypt files on the system, appending a “.ENCRT” extension to each affected file. Additionally, this ransomware may spread through network vulnerabilities or self-propagate via removable storage devices. To mitigate the risk of infection, users should exercise caution with unsolicited emails, avoid downloading software from unverified sources, and maintain robust antivirus protection.

How to decrypt and restore .ENCRT files

Use automated decryptors

Download Kaspersky RakhniDecryptor

Use the following tool from Kaspersky called Rakhni Decryptor, that can decrypt .ENCRT files. Download it here:

Download RakhniDecryptor

There is no purpose to pay the ransom because there is no guarantee you will receive the key, but you will put your bank credentials at risk.

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 .ENCRT 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 Gunra 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:

How to protect computer from viruses, like Gunra Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

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. Gunra 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.
