Ufymmtjonc virus (Decryption Methods Included)

Ufymmtjonc virus Removal Guide

What is Ufymmtjonc virus?

Ufymmtjonc ransomware is a virus that encrypts files and marks them using a random appendix

Ufymmtjonc virusThe ransom note should encourage people to pay up since the message states that there are no other options.

Ufymmtjonc ransomware is the threat that locks files to have an opportunity to ask for the ransom. This demand can be set to 1 or even 5 and more Bitcoins or a different cryptocurrency. The amount depends on the particular version, but since the virus belongs to the Snatch ransomware family, we can note that paying shouldn't even be considered an option. When those files get marked using the .ufymmtjonc extension, the machine is fully infected and damaged. Besides the direct document, image, audio file encryption, this threat can affect processed and system data to ensure persistence.

Once the threat is done with encoding files, a ransom demanding message gets delivered on the system in the form of HOW TO RESTORE YOUR FILES.TXT file. This piece gets delivered on the desktop, in other folders with encrypted files, so the victim can see the file and read the message encouraging them to pay up to get the decryption tool. Developing the official decryption tool is not easy, and researchers take time to do so.

Type File-locking ransomware
Appendix .ufymmtjonc
Emails smtrx911@keemail.me, bcpfile17@tutanota.com
Family Snatch ransomware
Ransom note HOW TO RESTORE YOUR FILES.TXT
Distribution Mainly relies on malicious file attachments from spam emails, misleading and dangerous sites online with direct malware payload drops
Elimination The threat is a seriously damaging piece, so anti-malware tools should help with the proper cleaning and virus termination
Recovery File restoring can be possible with third-party apps or backups from external systems, system recovery is achievable with ReimageIntego or a similar tool

People who suffer from threats like this Ufymmtjonc cryptovirus and file damage only want to focus on data recovery. This process can get difficult if you do not pay attention to what happened and what got affected. You need to remove the virus instead of contacting these criminals and then think about the file restoring. Adding any copies of the files can result in secondary encryption or loss of money when you pay for the useless tool or key. Backups are the better option since these file copies are the source you can control.[1]

The message that virus developers try to encourage people into paying:

!!!Hello!!!
All your files are encrypted and only I can decrypt them.
My mail is

smtrx911@keemail.me or bcpfile17@tutanota.com

Write me if you want to return your files – I can do it very quickly!

Attention!
Do not rename the encrypted files, because of this you can lose them forever!!!!!
To prove that we are not scammers and really can decrypt your files,
you can send three files for test decryption !!! (except databases, Excel and backups)

PLEASE DO NOT CREATE A NEW LETTER! RESPOND TO THE
LETTER TO THIS LETTER.
This will allow us to see all the history of the census in
one place and respond quickly to you.

The first stages of the infiltration can yet cause system damage

Ufymmtjonc ransomware spreads silently, and users can't spot the exact time when the payload gets dropped, unfortunately. It is because malspam campaigns can trick people into visiting sites, clicking on links, or opening the attached file. The distribution is quick because once the victim opens the attached word file, macro viruses[2] get triggered, and the payload file is dropped on the machine.

Then the only thing you as the user need to do is ignore the slowness of the device and suspicious features, so the virus is running until those encoded files get locked. Unfortunately, that can happen quickly, and you will receive the message a few moments after the payload drop. However, file encryption is not the only issue that this infection can cause.

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 cannot do 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 reinstallation 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 can also remove malware that has already broken into the system thanks to several engines used by the program. Besides, the application can also fix 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
  • The analysis of your machine will begin immediately
  • 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 if things go very wrong for one reason or another.

You need to remove the infection before you even try to restore files yourself. We already mentioned that researchers hadn't released a trustworthy decryption tool for this version, but the time you need to wait for such an application is too long if you want to use the PC right now.

Removing the threat can be difficult due to the changes made to the system, but the detection rate[3] shows that anti-malware tools can be used to eliminate the Ufymmtjonc virus properly. Run a tool like SpyHunter 5Combo Cleaner or Malwarebytes that is designed to find infections and trust the process. Once the ransomware is eliminated, you can safely move on to file recovery.

Encryption and file-locking: ways to restore .ufymmtjonc marked files

Ufymmtjonc ransomware is not created by ordinary people. This is the program made by criminals focused on cryptocurrency extortion, so your belongings are not important to them. Your direct contact with them can encourage malicious actors to send the additional malware instead of disclosing the ransom amount. Stay away from the virus and remove it as quickly as you can.

Encryption is the process that is successful due to the encryption algorithms that change the original code of the document, video, audio file, or image. This takes a few minutes, so your files can get locked immediately after clicking on the malicious file or hyperlink. Once the marker is there, the file is unopenable and cannot be seen or read ever again.

Decryption is the solution for encrypted files, but the unique key is needed for the decoding tool to work. It is not common for threat developers to release such tools without interference from law enforcement. However, there are ways to restore those pieces affected by the Ufymmtjonc virus.

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.

Ufymmtjonc ransomwareThe random file marker is the sign of a particular Snatch ransomware family.

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.
  3. Follow on-screen instructions to install the software.
  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.Select what to recover
  6. Press Next.
  7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
  8. Press Scan and wait till it is complete.
  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

The threat can affect many parts of the computer, but you need to remove the infection and recover the proper performance to fight the Ufymmtjonc ransomware virus once and avoid possible damage, future infiltrations. Anti-malware tools should serve you when the virus termination is needed; other methods can be alternate, but try to go through the steps below to fully get rid of the virus.

Getting rid of Ufymmtjonc virus. Follow these steps

Important steps to take before you begin malware removal

File encryption and ransomware infection are two independent processes (although the latter would not be possible without the former). However, it is important to understand that malware performs various changes within a Windows operating system, fundamentally changing the way it works.

IMPORTANT for those without backups! → 
If you attempt to use security or recovery software immediately, you might permanently damage your files, and even a working decryptor then would not be able to save them.

Before you proceed with the removal instructions below, you should copy the encrypted files onto a separate medium, such as USB flash drive or SSD, and then disconnect them from your computer. Encrypted data does not hold any malicious code, so it is safe to transfer to other devices.

The instructions below might initially seem overwhelming and complicated, but they are not difficult to understand as long as you follow each step in the appropriate order. This comprehensive free guide will help you to handle the malware removal and data recovery process correctly.

If you have any questions, comments, or are having troubles with following the instructions, please do not hesitate to contact us via the Ask Us section.

IMPORTANT! →
It is vital to eliminate malware infection from the computer fully before starting the data recovery process, otherwise ransomware might re-encrypt retrieved files from backups repeatedly.

Restore Windows "hosts" file to its original state

Some ransomware might modify Windows hosts file in order to prevent users from accessing certain websites online. For example, Djvu ransomware variants add dozens of entries containing URLs of security-related websites, such as 2-spyware.com. Each of the entries means that users will not be able to access the listed web addresses and will receive an error instead.

Here's an example of “hosts” file entries that were injected by ransomware:

Hosts file

In order to restore your ability to access all websites without restrictions, you should either delete the file (Windows will automatically recreate it) or remove all the malware-created entries. If you have never touched the “hosts” file before, you should simply delete it by marking it and pressing Shift + Del on your keyboard. For that, navigate to the following location:

C:\\Windows\\System32\\drivers\\etc\\

Delete Windows "hosts" file

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
  2. Scroll down to pick Update & Security.
    Update and security
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find Advanced Startup section.
  5. Click Restart now.
    Reboot
  6. Select Troubleshoot. Choose an option
  7. Go to Advanced options. Advanced options
  8. Select Startup Settings. Startup 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 Ufymmtjonc and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

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. 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 the server or network manager that needs to monitor connections and activities. 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.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
