Ragnarok ransomware

Ragnarok ransomware is the threat that marks encoded data with a .ragnarok_cry file extension after encryption

Ragnarok ransomwareRagnarok ransomware is the cryptovirus that encrypts common types of files such as audio, video, image files, and documents, or databases, and even archives, so developers have a reason to demand large payments for alleged file recovery. The ransom demand is delivered with a file named How_To_Decrypt_My_Files.txt that provides more details about the encryption process and contact information, as well as ways to get cryptocurrency needed for purchasing the decryption key from criminals. This threat was discovered by a researcher Karsten Hahn[1] in the middle of January and reported by other sources because crypto-malware got involved in huge attacks against companies and their customers.[2]

The name of this Ragnarok ransomware virus was in the headlines of news sources when it was discovered that specific vulnerability in the Citrix Application Delivery Controller allowed attackers to execute the arbitrary code and install malware on the targeted network. The company released patches for their software and the particular CVE-2019-1978 flaw, but many potential victims may not get the patch for their software or might already be affected by the cryptovirus, so you if you might be one of them, take actions immediately.

Name Ragnarok ransomware
File marker .ragnarok_cry or .ragnarok
Ransom note How_To_Decrypt_My_Files.txt
Contact email [email protected]
Distribution Threat gets delivered via spam email campaigns with infected email attachments and by exploiting various vulnerabilities that allow attackers to get into targeted systems and execute needed malicious processes
Symptoms The virus gets on the machine and encrypts various files in common types like photos, videos, documents. Then files get marked and the ransom note delivered with an encouraging message to pay up
Danger Ransomware can freely run in the background, affect functions, processes and disable some functions of the system to keep the persistence. Also, ransomware behavior involves blackmailing and often leads to loss of money or personal data
Elimination To delete Ragnarok ransomware, you need a proper anti-malware tool. Such software can detect threats and clean the machines
Repair Malware can affect processes and damage important files besides the encryption, so get a PC repair tool or a system optimizer and run it to fix such damage. Try Reimage Reimage Cleaner

Ragnarok ransomware infection spreads with the help f payload droppers that initiate the installation of the threat when the malicious script gets triggered by enabling the macro viruses or when the other malware injects already infected machine with a payload of cryptovirus. Once it gets on the machine t can run in the background and change needed system settings or disable/ install programs and functions. However, the first and the most dangerous, noticeable feature if this type of malware is encryption.

Ragnarok ransomware changes the original code of the chosen data by relying on the encryption algorithms that allow the virus to make files useless and unopenable. When that is done, the virus shows instructions in the form of a text file, in this case, named How_To_Decrypt_My_Files.txt that presents the following message to victims:

#what happend?

Even though all the claims seem convincing and the message scares you into consideration to pay these criminals, there is no reason to pay extortionists, especially, when money is the only aim of such malicious actors. You should remove Ragnarok ransomware instead and try to recover the system back to normal to restore those encrypted files using third-party programs or some system functions that could help.

The best way to react after you got affected by a threat like Ragnarok ransomware is to gather some of those encrypted files alongside other data related to this infection and store on an external drive, in case, decryption tool will be released by some experts[3] or malware researchers. Then you should get a tool falling into the anti-malware software category and scan the system fully.

Ragnarok ransomware removal cannot be that difficult, especially when AV detection is pretty high for the payload of this particular cryptovirus. That means that most of the anti-malware available to this day can find the threat and remove it from the machine, you just need to choose the proper program and run a full system scan. Then follow the suggested steps and clean the system from malware traces.   Ragnarok ransomware virus
Ragnarok ransomware – a virus that can be detected as malicious based on its behavior and files planted on the system.
Unfortunately, Ragnarok ransomware is not the threat that only encrypts files ad awaits for payment transfers to come. Extorsiotinsts want victims to pay for the alleged restoration of files but there are more changes the threat manages to do in the background of the system to keep running on the device. 

Ragnarok ransomware can make entries in the Windows registry, launch and repress processes in the system, inject other malware directly or open backdoors for remote access. There are many versions of secondary payload that ransomware can execute behind the victim’s back and do that successfully while the person is focusing on recovering those encoded files. Some files can get deleted to keep fewer data recovery methods for the person.

Nevertheless, altering those parts of the system yourself can be as damaging as the changes the virus does on the machine, so we don’t recommend searching for manual solutions with virus damage as well as with the termination of this infection. To tackle those affected parts and damaged data, get a tool that can run a scan on the system and find changes that Ragnarok ransomware did. Reimage Reimage Cleaner could be the tool that finds and fixes damaged files for you. Then you can be sure that ransomware is not going to renew itself and that your recovered files are safe.  Ragnarok ransom-demanding virus

Pay attention to details and avoid malware infiltrations

When you get emails on the daily, you should consider every one of them as potential spam and pay attention to the sender and the topic before you even get to open the notification. If you are not expecting to get financial information-related emails from a company or service, you should never open such a message.

Malicious actors use company names, services, government agencies to trick people that they have received an order or receipt details, payment information and so on, so the victim falls for the scam. Once the message is opened and the file attached to the email downloaded the only step left is to enable macros or visit the linked URL. Users often go straight to the suggested step and do that without thinking.

You need to look out for any misspelled company names, typos or grammar mistakes and letters from companies you don’t have a relation with. This is how you can avoid serious infections. Also, keeping the system virus free with a proper anti-malware or security tool.
