ShivaGood virus Removal Guide
What is ShivaGood ransomware?
ShivaGood ransomware is a file locking virus that uses several other malware components
ShivaGood ransomware is a file locking virus that appends .good extension to all the encrypted files
ShivaGood ransomware is malware, which first showed up in the wild back in September 2018, attacking several businesses and regular computer users. Since then a few other variants emerged, although they all append the same extension to files – .good. The attackers ask to pay a ransom in Bitcoins for the decryption tool and provide firstname.lastname@example.org, email@example.com, or firstname.lastname@example.org emails for communication purposes.
ShivaGood ransomware, otherwise known as Mimicry ransomware, takes numerous characteristics from different malware: the same file extension was used by Scarab-Horsia, while initial identifications of a sample pointed at Crypt0L0cker due the name of the ransom note – HOW_TO_RECOVER_FILES.txt. Nevertheless, it turned out that it has nothing to do with these two families, and its a modified version of the open-source HiddenTear ransomware, which makes it secure. In other words, ShivaGood virus-encrypted files cannot be decrypted, and the server used by hackers turns out to be dead as well, so paying a ransom is useless.
|Alternative names||Mimicry ransomware, .good ransomware|
|Derives from||HiddenTear – the open-source ransomware|
|Main executable||Frost.exe which is dropped into “Frenchkiss” folder|
|Encryption algorithm||Malware applies AES cipher to lock all files located on the system, although it skips .exe and system files like .sys or .dll|
|File extension||Each of the files is marked with .good extension. Encrypted example: picture.jpg.good|
|Ransom note||HOW_TO_RECOVER_FILES.txt is dropped on the desktop and all the folders where encrypted data is located|
|Contactemail@example.com, firstname.lastname@example.org, or email@example.com|
Paying criminals is useless, as the server the malware is meant to contact is no longer accessible, so they will not be able to recover the data – even after the Bitcoin payment. Other options are as follows:
|Malware removal||Use reputable anti-malware software to get rid of ShivaGood. If not successful, you should run a different malware removal tool and/or access Safe Mode with Networking as explained below|
|Windows system recovery||In case your Windows system is crashing, returning BSODs, errors and similar, you can remediate your OS with the help of PC repair software ReimageIntego|
There is no precise information on how ShivaGood ransomware spreads. However, because hackers are keen to attack businesses, there is a high chance that the malware compromises servers and networks via weakly protected Remote Desktop connections. Other methods might include:
- Spam emails;
- Fake updates;
- Cracks, etc.;
Soon after the infection, the ShivaGood virus creates a folder named “Frenchkiss and places the frost.exe file inside it. From there, the executable is launched, and the infection of the computer, along with all the connected networks as well as servers, begins.
ShivaGood ransomware performs various modifications to the host machine, including dropping several malicious files, modifying the Windows registry, deleting Shadow Volume copies, etc. All the changes to the system are initiated for a different purpose; for example, registry modification ensures that the malware is booted with each system start while deleting of automatic Windows backups makes automatic recovery impossible. Nevertheless, after ShivaGood ransomware removal, victims can fix the damage done by the virus with the help of such tools as ReimageIntego.
ShivaGood is a ransomware-type virus that derives from the HiddenTear family
As soon as preparations are complete, ShivaGood ransomware locks all files with the help of the AES encryption algorithm, restricting the access to all data, although the system and executable files remain untouched. Likewise, all the encrypted files are marked with .good extension.
The ransom note HOW_TO_RECOVER_FILES.txt states the following:

As mentioned before, contacting hackers is useless, as they themselves would not be able to retrieve the required key for the data decryption. Instead, we would suggest focussing on ShivaGood ransomware removal with the help of anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes. In case of troubles, we provide full instructions on how to enter Safe Mode if malware is preventing security tools from working correctly.
Protect the RDP and apply other precautionary measure to reduce the infection chances to a minimum
As previously mentioned, there is a high chance that malicious actors are using unprotected Remote Desktop connections to infect victims with malware. The principle of this infection method is relatively simple, as crooks employ automated software that scans the internet for poorly protected connections (those running the default TCP port 3389) and then brute-force their way in with the help of other tools. As a result, the attackers gain access remotely and install ransomware manually. RDP attacks are extremely prevalent when it comes to malware attacks on businesses and organizations. Nevertheless, regular users using the feature are also in danger, so it is important to protect RDP connections with strong passwords and correct configuration settings.
Since many ransomware developers use several different tactics for distribution, it is vital to make sure that other precautionary measures are also practiced. Security experts at dieviren.de provide the following security tips:
- Backup all important data regularly;
- Equip your machine with comprehensive security software;
- Employ additional security tools like ad-blocks and a firewall;
- Patch your Windows OS along with all installed programs with security updates;
- Use strong passwords for all your accounts and never reuse them;
- Never download pirated software installers or cracks/keygens/loaders.
ShivaGood ransomware file encryption process might be as fast a few seconds, while it might take up to several minutes if the machine is connected to a server
Delete ShivaGood ransomware before trying to recover the encrypted data
Many users are perplexed about what to do once they are hit by ransomware, as most never encountered it or never even heard of it before. As a general rule, security researchers claim that many cryptomalware viruses simply self-delete after performing the encryption routine. Nevertheless, some might also infect additional modules that steal sensitive data or remain on the system until terminated. Therefore, ShivaGood ransomware removal should always be performed.
Nevertheless, before you remove ShivaGood ransomware, you need to make a copy of encrypted files, as the process might damage them permanently – and the same goes for the recovery. Thus, copy all the encrypted data to the USB flash or a remote server, and then scan your system with anti-malware software to get rid of all the malicious components ShivaGood virus might have dropped. If the malware is tampering with your AV, access Safe Mode, as explained below.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
