Tips To Restore Files from Ragnarok ransomware
Ragnarok ransomware is a file encrypting virus that belongs to the ransomware family. It is mainly designed to lock down the target System and encrypt all types of personal and System files as well as force the victim to pay ransom money. It is able to easily invade all version Windows Based Operating system including the latest version Windows 10. It gets inside into the target system without any users knowledge with the spam email attachments and other tricky ways. Once gets inside into the targeted PC successfully, then it starts to encrypt all personal and system files of the compromised system by using a powerful encryption algorithm AES and RSA. After that it makes all the files totally inaccessible for the users by renames their file names by appending “.ragnarok_cry” extension. That is why victims are unable to open even single file as earlier. While victim try to open even single file then the ransom note “How_To_Decrypt_My_Files.txt” appears on the system screen which demands ransom money.
The ransom note “How_To_Decrypt_My_Files.txt” contains a text message which states that victim’s personal and system files including word, documents, text, images, photos, videos, audios have been encrypted but not damaged. So it is possible to restore data and files to their original condition if a decryption key is purchased from the cyber-criminal within two days. Otherwise it will delete and encryption is impossible. In order to receive decryption key victim have to paid unspecified money. In order to know how to purchase the decryption key and other more information victim are highly advice to send an email to the cyber-criminal by using the provided email address.

Prevention tips to protect your System from Ragnarok ransomware related attacks in future
- You should have strong backup of all files and data stored in your computer because some ransomware is designed to look for network shares and encrypt all files stored in your machine. You would do well to store data backups on secure cloud server with high-level encryption and multiple-factor authentication.
- Ransomware type virus often relies on exploit kits to gain illicit access to a System or network. If you run outdated or obsolete software on your computer, then you are in risk of ransomware because the software developers are not putting out security updates anymore. To remove abandonware and replace it with software still being supported by manufacturer.
- The cybercriminals behind ransomware attack are using former banking Trojan as delivery vehicle for ransomware. It relies on malspam to infect your System and get foothold on your network. Once it gain access to your network, it shows worm like behaviour spreading from System to System using list of common passwords.
- You should be alert while surfing online and avoid installing freeware from unknown sources, stop opening attachments coming from unknown emails and click on ads or popup messages after double reading.
- Don’t pay extortion money in case of attack. We recommended you to stop paying ransom and FBI agrees. Cybercriminals don’t have scruples and there is no guarantee you will get files back. By paying extortion money, you are showing cybercriminals that ransomware attack work.
RAGNAROK ransomware on a rise in 2020
Contents
- RAGNAROK ransomware on a rise in 2020
RAGNAROK is a malicious ransomware-type virus which encrypts files on victim’s computer. The data encryption restricts access to these files. The virus marks affected files with .ragnarok extension and leaves a ransom note called !!ReadMe_To_Decrypt_My_Files.txt in every folder. The ransomware suggests contacting the attackers via [email protected], [email protected] or [email protected] to get a specific ransom price. The note threatens to make victim’s data public if the cybercriminals’ requirements aren’t followed.
RAGNAROK ransomware asks for approximately 1 Bitcoin for one infected PC, or 5 Bitcoins for computers on infected server. As specified in the ransom note, the attackers will specify an exact sum of money in Bitcoin after receiving victim’s ID.
Currently, there are no known ways to decrypt .ragnarok extension files for free. Victims who have data backups should remove the virus as soon as possible and restore data using external data storage devices.
Threat Summary
The behavior of the ransomware explained
Once executed on the target system, Ragnorak file virus first checks the language ID of Windows. It has a language exclusion list that shuts down the malicious process and doesn’t perform encryption if the victim’s PC is set to one of the listed languages:
- 0419 = Russia;
- 0423 = Belarus;
- 0444 = Russia;
- 0442 = Turkmenistan;
- 0422 = Ukraine;
- 042c = Azerbaijan;
- 0426 = Latvia;
- 043f = Kazakhstan;
- 0804 = China.
It must be noted that ransomware developers who are based in Russia or other CIS countries rarely exclude China.
If the ransomware detects any other language ID, it gives a greenlight for the attack to begin. The first thing that it does is attempt to disable Windows Defender by adding group policies in Windows Registry. The ransomware injects the following rules:
- HKLMSOFTWAREPoliciesMicrosoftWindows Defender “DisableAntiSpyware” = 1
- HKLMSOFTWAREPoliciesMicrosoftWindows DefenderReal-Time Protection “DisableRealtimeMonitoring” = 1
- HKLMSOFTWAREPoliciesMicrosoftWindows DefenderReal-Time Protection “DisableBehaviorMonitoring” = 1
- HKLMSOFTWAREPoliciesMicrosoftWindows DefenderReal-Time Protection “DisableOnAccessProtection” = 1
These attempts will be unsuccessful if the victim has Windows 10 Tamper Protection feature on.
Next, Ragnarok malware tries to delete Volume Shadow Copies (to prevent data recovery), then disables Windows auto startup repair feature, and turns off Windows Firewall by executing these commands via cmd:
- /c vssadmin delete shadows /all /quiet
- /c bcdedit /set {current} bootstatuspolicy ignoreallfailures
- /c bcdedit /set {current} recoveryenabled no
- /c netsh advfirewall set allprofiles state off
When the preparation tasks are completed, the ransomware begins data encryption. It uses AES encryption to generate the encryption key, which is then encrypted with a packed RSA4096 key. This ensures that only the virus’ developers can restore the encryption key.
The ransomware skips executive files, also .dll and .sys files, and the files that have already been encrypted by the virus (those with .ragnarok extension). As usual, the ransomware bypasses files essential for operating system to function.
The ransomware targets unpatched Citrix ADC servers
RAGNORAK virus is known to be targetting Citrix ADC servers with unpatched vulnerability which is known under CVE-2019-19781 code. Although the vulnerability is now patched, networks who fail to install the update are open to attacks and the said ransomware infection. The Citric vulnerability has also been exploited by Sodinokibi ransomware developers.
The EternalBlue vulnerability in Citrix ADC servers allow the attackers to perform arbitrary code execution remotely. In particular, the attacker can insert a specific DLL that is capable of downloading and launching Ragnorak ransomware payload on the computer or the whole computer network instantly.
