Remove Stupid ransomware / virus (Virus Removal Guide) - Jul 2020 update

removal by Alice Woods - - | Type: Ransomware

Stupid – open-source ransomware that has a numerous variants 

Stupid ransomwareStupid ransomware is a file locker that encrypts data and urges a ransom for the decryption software

Stupid ransomware – a malicious program that can easily encrypt victim's files and leave them unreadable. Just like Annabelle ransomware, it belongs to the notorious group of crypto-viruses that are using the .NET programming language. The main difference between these variants is the extension appended to each of the infected files. Currently, malware is known for adding these suffixes:

  • .haters,
  • .xncrypt,
  • .mikoyan,
  • .failedAccess,
  • .xmdXtazX,
  • .try2Cry.

Stupid ransomware code is open on Github. It means that volunteer hackers can use the code for building customized versions without any restrictions. The latest version of this ransomware has been detected at the beginning of July 2020 by a G DATA team[1]. Dubbed as Try2Cry ransomware, the virus has a unique trait to worm USB flash drives. The number of extensions that it is capable of locking is rather low (up to 10), they are the most widely used and contain the most sensitive users' data. 

Questions about Stupid ransomware virus

It's not clear how much money the hackers expect to get for the Try2Cry virus and other Stupid variants decryption key. Nevertheless, experts do not recommend paying for the decryptor because most of the versions can be deciphered using a fully functional free Stupid decryptor. You can find download links below.

Locked files The ransomware virus is capable of locking 61 types of files. This includes images, word documents, audios, videos, and other files/documents
Distribution Such malware is spread via hacked RDP, malicious email messages and their infectious attachments, outdated software, etc.
Prevention Always manage your email, do not open any letters that look suspicious to you. Also, keep your software regularly updated, employ antimalware protection, etc.
Removal Get a tool such as Reimage Reimage Cleaner Intego to perform a full system scan. Afterward, continue to the end of this article where you will find automatical removal guidelines
Data recovery Some data recovery solutions have been added to the end of this article. In addition, you can use the official decryption key that is available for Stupid ransomware variants

Stupid virus is designed to corrupt 61 file types, including various image, audio, video and text files, that are stored in:

  • My Pictures,
  • My Music,
  • Downloads,
  • and other C:\\Windows and C:\\Programs top-level directories.

Following data encryption, Stupid ransomware gives victims instructions on how to redeem encrypted files. It’s unknown how much money it asks to pay; however, you should not consider this option. If you are thinking about paying the ransom, let us tell a few possible scenarios that should discourage you from reaching for your credit card.

Hackers are not obliged to recover your files. Ransomware is their illegal source of income, and they are interested in getting money. Keeping their promise to recover your data is a matter of their conscience. Thus, they may not provide a Stupid decryptor at all.[2]

If you decide to pay the demanded sum of money, you can always be asked to transfer more Bitcoins. Otherwise, authors of the Stupid malware might threaten to delete your files or cause other damage to the device. What is more, you might purchase not working or infected decryptor, and suffer from other malicious programs.

Thus, you should forget your damaged files for a while and remove Stupid ransomware using Reimage Reimage Cleaner Intego or another malware removal program. However, before installing security software, you may need to reboot your computer to Safe Mode with Networking first. You can find how to achieve such a task at the end of the article.

Some great news is that cybersecurity experts have already released a decryption tool for files that got touched by Stupid ransomware. Released by Michael Gillespie, the product works for Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10 versions. Additionally, the tool is active for both 32-bit and 64-bit-based operating systems.[3]

Stupid ransomware virusStupid ransomware is a notorious malware form that holds several alternative versions

At the end of the article, you will find detailed Stupid removal instructions, as well as alternative data recovery methods. Keep in mind that all infected directories and locations need to be cleaned from harmful content, otherwise, the ransomware virus might boot itself up within the next computer restart. Criminals inject malicious components into places such as the Windows Registry[4] and Task Manager.

In addition, note that dangerous malware such as Stupid ransomware might be able of modifying the Windows hosts file.[5] Such type of activity is performed in order to prevent Windows users from accessing security-related websites and forums. Once you are uninstalling the ransomware virus, you have to delete the corrupted hosts file in order to unblock access.

Versions of the Stupid ransomware virus

Haters ransomware virus. 

Authors of the ransomware were definitely inspired by the success of the Cerber. They claimed that Haters virus is a new version of a well-known cyber infection. It uses CryptoCerber.exe or Cerber3Ransomware.exe executables in order to run data encryption procedure on the affected computer.

During data encryption, it appends .haters file extension and shows up a ransom note called “Form 2” where victims are asked to pay the ransom. However, the virus is decryptable by entering this code into the ransom-demanding window: masihmaubullyguaanjeng. 

FailedAccess ransomware virus.

The significant feature of the ransomware is that it encrypts files on Desktop\projet sans fils\test folder only. All pictures, documents, multimedia and other files stored in this location is marked with .FailedAccess file extension.

Following data encryption, it triggers a ransom note in “You are Hacked by J.H” program window. Despite the fact users are asked to pay an unknown sum of money; there’s no need to follow such instructions. The virus is decryptable with a Stupid Decryptor.

Mikoyan ransomware virus.  

It’s a poorly written ransomware that appends .mikoyan file extension to the encrypted files. As soon as all files are locked, the virus opens a “MIKOYAN ENCRYPTOR” window. It’s a ransom note where criminals in a broken English tell to pay 1 Bitcoin and send an email to mikoyan.ironsight@outlook.com.

However, wasting the money and paying the ransom is unnecessary. Previously mentioned Stupid Decryptor could recover these files for free.

XmdXtazX ransomware virus. 

This version of ransomware pretends to be a warning message from the Federal Bureau of Investigation (FBI). The XmdXtazX virus threatens to delete all files if victims don’t transfer 35 euros within 24 hours and don’t send an email to wcffedde-1559@ycrcrtwlf.com. However, you should rush to remove the virus only.

You can type this code – 666444QSW6842QSW666444 – to the ransom-demanding window and rescue your files for free. However, once files no longer have .XmdXtazX extension, you should take care of your computer’s security by scanning the system with antivirus.

Suri ransomware virus.

This malware is another strain of the so-called Stupid ransomware. Once the virus manages to sneak into your Windows system, modifies entries, and launches the encryption process. When files are locked with secret keys, all of the documents end up with the .SLAV appendix and ransom demands start flooding victims through a ransom message that urges for 100 euros that need to be transferred in BTC cryptocurrency.

Stupid malware

Try2Cry ransomware virus has been revealed at the beginning of July 2020 by Karsten Hahn – a team member of the G DATA team. The ransomware may be spread via typical ransomware distribution means (spam emails, cracks, keygens, fake updates, etc.), though it stands out from the others due to the USB worm traits. 

According to the researcher, the Try2Cry virus is capable of infecting USB flash drives by copying the Update.exe malicious file onto the connected drive and altering the existing files on it by adding the LNK shortcut. In addition, it generates several folders named using Arabic symbols. Once any of the malicious files is launched, the ransomware launches the Rijndael algorithm and encrypts the .doc, .ppt, .jpg, .xls, .pdf, .docx, .pptx, .xls, and .xlsx files using .try2cry file marker. 

Although criminals are expecting the victims to contact them via Try2Cry@Indea.info email, experts recommend the only solution – a full Try2Cry removal using a professional anti-virus tool. This ransomware worm can be decrypted using the Stupid decryptor (the link provided below), so make sure to delete the virus from the machine and USB and then launch the decryption tool.

Security tips that will help to avoid ransomware

Developers of Stupid ransomware might use several strategies to spread malware and infiltrate devices. However, if you take precautions, you should not encounter ransomware. File-encrypting viruses can enter the system when you open a malicious email attachment, click on a malware-laden ad, install bogus software or fake update, etc. Thus, you should:

  • Stay away from spam emails[6] and do not open any attachments that are included in unknown emails.
  • Keep all your software updated.
  • Do not install any programs or updates from unknown or shady sources.
  • Avoid clicking suspicious ads, especially those that inform about detected viruses or offering to install software are dangerous!

In addition, we have noticed that some ransomware strains are able to distribute via hacked RDPs. According to research, the TCP port 3389 is the most vulnerable one that allows criminals to hack it and forcibly push the password in order to access the targeted machine remotely.

Lastly, you should be prepared for the worst and regularly update data backups.[7] They are crucial in case of the attack. The research team from Finland[8] reminds that not all ransomware-viruses are decryptable, so it’s better to keep copies of the most important files in the external storage device.

Terminate Stupid ransomware with the help of professionals

The only safe way to remove Stupid ransomware is to employ professional security programs. It’s nearly impossible to delete the file-encrypting virus manually without causing bigger damage because it can inject malicious code into legitimate system processes. Thus, you should install a powerful malware removal program to complete the elimination task. Taking risks and trying to complete the elimination on your own might bring big damage to your computer system or its software.

In order to lengthen the Stupid removal process for your computer, you can try scanning the entire system and look for malicious strings with a product such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes. These tools will observe all infected directories and provide you with results regarding the altered software and system locations. Once you eliminate the cyber threat, go to the very end of this article and there you will find data recovery solutions, including the original decryption tool.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Stupid from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If you have approached various encrypted data that was unknowingly touched by Stupid ransomware or its alternative versions, you have the possibility of recovering your files and documents. Below you will find a few methods regarding the file restoring process.

If your files are encrypted by Stupid, you can use several methods to restore them:

Try to restore files encrypted by Stupid ransomware using Data Recovery Pro

This professional software has already helped thousands of victims of ransomware. Hopefully, it will help to restore and your files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Stupid ransomware;
  • Restore them.

Access the most important files using Windows Previous Versions feature

If the System Restore method has been enabled before Stupid ransomware attack, you can copy individual files. By following the steps below you will be able to access previously saved versions of the encrypted files.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Use ShadowExplorer for data recovery

If Stupid malware did not delete Shadow Volume Copies of the targeted files, you may find ShadowExplorer handy as well.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Stupid Decryptor

Some versions of the Stupid ransomware virus can be decrypted with Stupid Decryptor. You can download it from here.

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

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
