Satan Ransomware Removal Guide

What is Satan Ransomware?

Satan Cryptor is a dangerous virus that promises to delete personal files if the victim fails to pay a ransom

Satan Ransomware illustrationThere are numerous versions of the ransomware and the number will keep increasing

Satan ransomware is a crypto-virus which operates as Ransomware-as-a-service.[1] Alternatively, it is also known as Satan Cryptor and Satan Cryptor 2.0 which came back in 2020. Malware is spread via Server Message Block (SMB) exploit that was used by a scandalous Wannacry attack. However, it is still unknown if the virus is related to the previously-released ransomware that was presented in the underground market[2].

This crypto-malware appends the .satan extension and drops the HELP_DECRYPT_FILES.html or similar file as the ransom note. Originally, the ransomware creators required 0.5 BTC to be paid as the ransom. However, it seems like the amount of ransom decreased with the latest version, demanding 0.3 Bitcoin. The biggest changes to get infected are if you live in the USA, China, and Korea.

SUMMARY
Name Satan Cryptor
Type Ransomware/crypto virus/malware
Extension .satan file extension
Ransom note The virus is using HELP_DECRYPT_FILES.html and # SATAN CRYPTOR #.hta files to warn the victim about the encrypted data
Danger Level High. Encrypted files are unusable, the victim is demanded to pay a ransom
Targets users in Korea, China and USA
Distribution SMB exploit, spam emails, malicious websites
Elimination Fully scan your system with anti-malware tools. Manual removal not recommended
Repair Virus damage can be eliminated and fixed using ReimageIntego

Previously, crooks were offered to design their own Satan ransomware and start generating illegal profits from this hazard. They were encouraged to sign up and create their individual file-encrypting variants of ransomware. The malware creation procedure consisted of the following parts:

  1. Malwares;
  2. Droppers;
  3. Translate;
  4. Account;
  5. Notices;
  6. Messages.

Malware allowed its users to specify their ransomware settings. They were allowed to set the amount of the ransom, indicate how much it should increase and the period of time after which it should happen. Once the user finished completing this page, it was allowed to create malicious MS Office macros or CHM installers in the Dropper section which were used to distribute Satan Cryptor.

Satan ransomware imageSatan ransomware is offered as a service and its developers take 30% of the obtained profits.

Satan ransomware has also been spread in multiple languages. Once inside the system, it starts displaying such warning message:

Payment Time Left: XXXX
Some files have been encrypted
Please send 0.5 bitcoins to this wallet address: XXXX
If you paid, send the machine code to my email address
I will of give you key
If there is no payment within three days,
we will no longer provide a decryption support
We can give you the test file.
send 3 files that are smaller than 3 MB to my email address
Btc Wallet: [1BEDcx8n4PdydUNC4gcwLSbUCVksJSMuo8]
Mail Address: [satan_pro@mail.ru]

Note that there could be numerous versions of the threat and the number will keep increasing until people agree to pay the ransom. The developers of the file-encrypting virus promise to reduce their cut when the infection rate increases. It is clear that crooks are motivated to spread ransomware in order to gain a larger profit share.

Therefore, we recommend you to remove Satan Cryptor and do not pay the ransom under any circumstances. You should be aware that there are several reports on the Internet which inform that the decryption tool is ineffective and it is useless to spend such enormous amounts of money.

Be aware that SpyHunter 5Combo Cleaner or Malwarebytes is the best option to complete the virus removal for the regular computer user. Do not hesitate to do that since we also provide you alternative recovery methods at the end of this article to help recover data after a ransomware attack.

Satan ransomware returns in 2020

Malware analyst Bart published a tweet[3] regarding recent recurrence of Satan Cryptor. The new variant of the virus kills database-related processes and attempts to stop SQL-related[4] services.

Satan crypto-virusThe ransomware virus in depth

It seems like the extension applied to each of the infected files remains the same – .satan. The ransom note is also very similar to previous versions and is displayed in three different languages – English, Chinese and Korean. However, the amount of demanded ransom changed, which stands at 0.3 BTC.

Hackers are also accepting a personal file that can be sent to them, so they can show that decryption is possible. However, differently for its predecessors, the virus does not provide support for the decryption after three days of infection. It seems like crooks are trying to speed up the process by using scare tactics.

However, you should never get tricked into paying cybercriminals, regardless of how scary the situation might seem. There is no guarantee you will get your files back, and you will also be promoting illegal activities by supporting hackers.

Ransomware can be distributed in various ways

Computer hazards are distributed via multiple techniques to help infect as many computers as possible. The most widely used ones are malicious emails and obfuscate software updates. Both of them possess a deceptive appearance which tricks gullible people to open bogus files and install ransomware.

Users should be aware of the hidden dangers in spam emails. Usually, they hold a malicious attachment of the executable which infects the computer once clicked. Hackers impersonate invoices or job spot responses from famous companies or even governmental authorities. Thus, do not open suspicious emails despite how genuine they may look. You should check some phishing email examples online so that you would be able to spot suspicious emails straight away.

Additionally, it is common to place ransomware as obfuscate software updaters which might pop-up during browsing sessions. Note that the false alerts to fix problems related to Adobe Flash Player might be merely an attempt to lure you into downloading ransomware[5].

You should remove Satan ransomware without a delay

Since the ransomware has been offered as a ransomware kit which allowed creating customized versions of it, regular computer users might not be able to detect all components of the malware and fail to terminate it. Also, in some cases, it is possible to damage your computer system permanently when trying to get rid of this high-risk computer infection.

Therefore, Satan Cryptor removal is only possible with the help of a certified IT technician or a profession security software. Note that it is vital to make sure that the antivirus tool is reputable and powerful enough to identify and eliminate this dangerous computer hazard.

You can remove the ransomware with SpyHunter 5Combo Cleaner or Malwarebytes. Experts from LosVirus.es[6] assure you that these security programs are robust and able to terminate the ransomware within several minutes.

Getting rid of Satan Ransomware. Follow these steps

Identify ransomware affecting your PC

Modern-day ransomware had its roots in the early 2010s when cybercriminals began to understand the potential it has for money extortion. Over the years, thousands of new ransomware strains have been developed and spread all over the world, infecting regular consumers, small businesses, and high-profile organizations.

Because of the lucrative nature of ransomware, cybercriminals are creating new ransomware versions in the hopes of establishing themselves in this illegal business. Ransomware often uses different extensions, ransom notes, and other attributes that it can be identified by. However, quite often, this information can overlap or simply not be available, so identifying the threat might be difficult.

In order to deal with ransomware infection effectively, you must first identify it. Here are a few examples of how to determine the precise ransomware you are dealing with:

File extension

Almost all modern ransomware viruses are using extensions that are appended at the end of the original filenames. However, this is not a rule, and in some cases, cybercriminals change the name by replacing it with randomly generated characters, add the marker before the file name, or do not visually change the name of the file at all.

Here you can see an example of a unique extension .hhmgzyl that belongs to the Snatch ransomware family:

Hhmgzyl extension

If your files are appended with .exe, .locked, .encrypted, or other broadly-used extensions that are difficult to identify, proceed with the next step.

Ransom note

Ransomware family might sometimes be identified by the ransom note it uses. In most cases, cybercriminals create a simple .txt file and place it on users' desktops or other places that are easily reachable (typically, where the encrypted data is located). Other times, a pop-up window can also be used, which is launched as soon as the encryption is complete. In some cases, threat actors name the ransomware within this note:

Phobos ransomware

In some cases, it is possible to identify ransomware by its ransom note name, but they are typically very generic (e.g., FILES ENCRYPTED.txt, _readme.txt) and used by different cybercriminals groups.

Free ID Ransomware service

ID Ransomware is a free service that can easily let users identify the precise malware they are dealing with. All you have to do is upload the ransom note that can be found on the desktop and within folders where encrypted files are located and the sample of an encrypted file.

ID Ransomware

Soon after uploading the required files, you will be provided with all the relevant information, including what family ransomware belongs to and whether or not it is possible to decrypt files.

If none of the above helped you to identify which ransomware you are dealing with, you should use keywords (extension, contact email, ransom note contents, crypto-wallet address, etc.) to find the information on the internet.

Isolate the infected computer

Some ransomware strains aim to infect not only one computer but hijack the entire network. As soon as one of the machines is infected, malware can spread via network and encrypt files everywhere else, including Network Attached Storage (NAS) devices. If your computer is connected to a network, it is important to isolate it to prevent re-infection after ransomware removal is complete.

The easiest way to disconnect a PC from everything is simply to plug out the ethernet cable. However, in the corporate environment, this might be extremely difficult to do (also would take a long time). The method below will disconnect from all the networks, including local and the internet, isolating each of the machines involved.

  • Type in Control Panel in Windows search and press Enter
  • Go to Network and Internet Network and internet
  • Click Network and Sharing Center Network and internet 2
  • On the left, pick Change adapter settings Network and internet 3
  • Right-click on your connection (for example, Ethernet), and select Disable Network and internet 4
  • Confirm with Yes.

If you are using some type of cloud storage you are connected to, you should disconnect from it immediately. It is also advisable to disconnect all the external devices, such as USB flash sticks, external HDDs, etc. Once the malware elimination process is finished, you can connect your computers to the network and internet, as explained above, but by pressing Enable instead.

Scan your system with anti-malware

If you are a victim of ransomware, you should employ anti-malware software for its removal. Some ransomware can self-destruct after the file encryption process is finished. Even in such cases, malware might leave various data-stealing modules or could operate in conjunction with other malicious programs on your device. 

SpyHunter 5Combo Cleaner or Malwarebytes can detect and eliminate all ransomware-related files, additional modules, along with other viruses that could be hiding on your system. The security software is really easy to use and does not require any prior IT knowledge to succeed in the malware removal process.

Repair damaged system components

Once a computer is infected with malware, its system is changed to operate differently. For example, an infection can alter the Windows registry database, damage vital bootup and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstall is required.

Therefore, we highly recommend using a one-of-a-kind, patented technology of ReimageIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.

  • Download the application by clicking on the link above
  • Click on the ReimageRepair.exe
    Reimage download
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation process Reimage installation
  • The analysis of your machine will begin immediately Reimage scan
  • Once complete, check the results – they will be listed in the Summary
  • You can now click on each of the issues and fix them manually
  • If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically. Reimage results

By employing ReimageIntego, you would not have to worry about future computer issues, as most of them could be fixed quickly by performing a full system scan at any time. Most importantly, you could avoid the tedious process of Windows reinstallation in case things go very wrong due to one reason or another.

Restore files using data recovery software

Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.

While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.

Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:

  • Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
  • Only attempt to recover your files using this method after you perform a scan with anti-malware software.

Install data recovery software

  1. Download Data Recovery Pro.
  2. Double-click the installer to launch it.
    Launch installer
  3. Follow on-screen instructions to install the software. Install program
  4. As soon as you press Finish, you can use the app.
  5. Select Everything or pick individual folders where you want the files to be recovered from. Select what to recover
  6. Press Next.
  7. At the bottom, enable Deep scan and pick which Disks you want to be scanned. Select Deep scan
  8. Press Scan and wait till it is complete. Scan
  9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  10. Press Recover to retrieve your files. Recover files

Find a working decryptor for your files

File encryption is a process that is similar to applying a password to a particular file or folder. However, from a technical point of view, encryption is fundamentally different due to its complexity. By using encryption, threat actors use a unique set of alphanumeric characters as a password that can not easily be deciphered if the process is performed correctly.

There are several algorithms that can be used to lock data (whether for good or bad reasons); for example, AES uses the symmetric method of encryption, meaning that the key used to lock and unlock files is the same. Unfortunately, it is only accessible to the attackers who hold it on a remote server – they ask for a payment in exchange for it. This simple principle is what allows ransomware authors to prosper in this illegal business.

While many high-profile ransomware strains such as Djvu or Dharma use immaculate encryption methods, there are plenty of failures that can be observed within the code of some novice malware developers. For example, the keys could be stored locally, which would allow users to regain access to their files without paying. In some cases, ransomware does not even encrypt files due to bugs, although victims might believe the opposite due to the ransom note that shows up right after the infection and data encryption is completed.

Therefore, regardless of which crypto-malware affects your files, you should try to find the relevant decryptor if such exists. Security researchers are in a constant battle against cybercriminals. In some cases, they manage to create a working decryption tool that would allow victims to recover files for free.

Once you have identified which ransomware you are affected by, you should check the following links for a decryptor:

No More Ransom Project

If you can't find a decryptor that works for you, you should try the alternative methods we list below. Additionally, it is worth mentioning that it sometimes takes years for a working decryption tool to be developed, so there are always hopes for the future.

Create data backups to avoid file loss in the future

One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.

Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:

  • Backup on a physical external drive, such as a USB flash drive or external HDD.
  • Use cloud storage services.

The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.

Using Microsoft OneDrive

OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:

  1. Click on the OneDrive icon within your system tray.
  2. Select Help & Settings > Settings.
    Go to OneDrive settings
  3. If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
    Add OneDrive account
  4. Once done, move to the Backup tab and click Manage backup.
    Manage backup
  5. Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
  6. Press Start backup.
    Pick which folders to sync

After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).

Using Google Drive

Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.

You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.

  1. Download the Google Drive app installer and click on it.
    Install Google Drive app
  2. Wait a few seconds for it to be installed. Complete installation
  3. Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
    Google Drive Sign in
  4. Click Get Started. Backup and sync
  5. Enter all the required information – your email/phone, and password. Enter email/phone
  6. Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
  7. Once done, pick Next. Choose what to sync
  8. Now you can select to sync items to be visible on your computer.
  9. Finally, press Start and wait till the sync is complete. Your files are now being backed up.

Manual removal using Safe Mode

Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.

Step 1. Access Safe Mode with Networking

Manual malware removal should be best performed in the Safe Mode environment. 

Windows 7 / Vista / XP
  1. Click Start > Shutdown > Restart > OK.
  2. When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
  3. Select Safe Mode with Networking from the list. Windows 7/XP
Windows 10 / Windows 8
  1. Right-click on Start button and select Settings.
    Settings

  9. Press Restart.
  10. Now press 5 or click 5) Enable Safe Mode with Networking. Enable safe mode

Step 2. Shut down suspicious processes

Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Click on More details.
    Open task manager
  3. Scroll down to Background processes section, and look for anything suspicious.
  4. Right-click and select Open file location.
    Open file location
  5. Go back to the process, right-click and pick End Task.
    End task
  6. Delete the contents of the malicious folder.

Step 3. Check program Startup

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Go to Startup tab.
  3. Right-click on the suspicious program and pick Disable.
    Startup

Step 4. Delete virus files

Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:

  1. Type in Disk Cleanup in Windows search and press Enter.
    Disk cleanup
  2. Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
  3. Scroll through the Files to delete list and select the following:

    Temporary Internet Files
    Downloads
    Recycle Bin
    Temporary files

  4. Pick Clean up system files.
    Delete temp files
  5. You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):

    %AppData%
    %LocalAppData%
    %ProgramData%
    %WinDir%

After you are finished, reboot the PC in normal mode.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Satan Ransomware and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

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.
