Jjtt ransomware (Removal Instructions) - Decryption Steps Included

Jjtt virus Removal Guide

What is Jjtt ransomware?

Jjtt file virus controls processes to ensure the persistency of the infection

Jjtt ransomwareThe infection controls the behavior of the victims by demanding ransom for the recovery

The threat locks down the computer and demands particular payment for the promised decryption tool. Jjtt ransomware uses an encryption algorithm and changes the original code of the image, video, document, even archived file. This makes the data unopenable and useless on the machine. The worst thing about it is the fact that there are no options for file recovery here.

Jjtt file virus attacks and locks commonly used files, tricks people into paying the ransom. A strong encryption algorithm allows this threat to change the chosen data, so they cannot be opened anymore or used. The creators behind these programs intend on extorting money from unsuspecting victims through threats like this. Scaring people into transferring cryptocurrency payments via ransom note text file.

When it comes to ransomware, you're never safe because the threat can run in the background for a while. This virus can be downloaded and carried by using various methods to spread the threat including downloading pirated content or malicious files from email messages without knowing what is included there.[1] The infection is quick, and you may see no symptoms until encrypted data gets locked down with a marker .jjtt.

What is the ransomware virus?

Cybercriminals are always looking for new ways to steal your money, so locking files away is one of them. They claim that the only way around this problem is by paying them off, but before doing anything else, think about all of those risks first. These threats should not be ignored because, if left unchecked could lead straight into major issues like losing data or even having files ruined permanently. However, the _readme.txt message is not the one that should be followed.

Unfortunately, the victim can't get their files back without paying the ransom or obtaining the decryption tool. There may be official tools developed for this type of malware that will decrypt it, but as far as we know there's no way currently in existence for Jjtt ransomware decryption. It takes time to develop such tools, and it is difficult since the threat is advanced and new.

The best advice would probably just involve removing infections and using backup copies instead. Eliminating the threat is the best option because repairing files on the infected machine can cause additional and permanent issues with the system. Jjtt file virus is a serious threat that can trigger problems with data and even the performance of the computer.

Step 1. Remove the infection

There is a common belief that paying the ransom will guarantee your data's security and recovery, but experts[2] recommend against this practice. Cybercriminals might not keep their promises resulting in financial losses for you.[3] Here we explain more how to deal with the Jjtt file virus by properly using available alternative methods. which may These steps should be taken as soon as possible since an infection can put a major strain on system resources during those additional processes.

The first tip is to ignore criminals and not consider paying or contacting them. These people are looking for your information, so you can't trust what they say on their sites. The crypto-virus will encrypt all important files on a Windows computer as well as restrict access. Contacting hackers via listed emails support@sysmail.ch, helprestoremanager@airmail.cc cannot get you anywhere.

Jjtt file virusThreat actors lock files to have the purpose for the money extortion

Don't believe any offers of discounts either because these tricks are only to encourage people more. Money transfers do not guarantee that threat is removed or that files get recovered. Remove Jjtt ransomware with applications like SpyHunter 5Combo Cleaner or Malwarebytes and make sure to terminate the threats related to the crypto-extortion virus.

Anti-malware tools help with the infection and security state of the system. These programs are not capable of decrypting encoded files or repairing system data, but the infection can be removed properly from the system and stopped, so the file recovery can happen safely. Otherwise, Jjtt file virus can run another round of encryption on the recovered files.

Step 2. Repair system data

Jjtt ransomware infects the machine and can cause various issues besides encryption. 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.

Unfortunately, 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 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 is also capable of removing Jjtt ransomware damage. 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 processReimage installation
  • The analysis of your machine will begin immediatelyReimage 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.

Step 3. Try the alternate option for the decryption

Jjtt file virus is a particularly dangerous member of the Djvu ransomware family. Its newest versions are constantly released and affect machines quickly due to the recent changes. Improvements allow them to spread and release new ones each week. This threat is spreading along with previously-distributed Ooii and Rtfg. Variants released after August 2019 are non-decryptable.

There are differences in encryption methods that affect the decryption options, and both offline and online keys can be in use. They're not always used interchangeably because there's a difference between them. Sometimes when servers cannot communicate with malware, offline IDs get used. It means that each version has one ID, and it is used for all devices.

Online keys that Jjtt ransomware mainly use are unique for each individual device that is affected by the threat. Decryption is only possible when the particular key is obtained as for the offline ids, researchers can have one key and decrypt data for many victims. However, these are not the options available right now.

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 behind the Jjtt file virus 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.
  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.

Jjtt file virus can be triggering the process that damages the machine and disable particular programs and computer functions. You can risk having the computer permanently damaged and files not only locked but destroyed if you do not remove the infection properly. This is where AV tools are needed because detecting ransomware is not easy.

Try running security software or anti-malware tool like SpyHunter 5Combo Cleaner, Malwarebytes, and terminate the infection fully. This way your machine is prepared for file repair and other processes. You still should check for virus damage with ReimageIntego and then go through the decryption options below, for example.

Getting rid of Jjtt virus. Follow these steps

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

Use Emsisoft decrytor for Djvu/STOP

If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.

Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.

  • Download the app from the official Emsisoft website. Download Djvu/Stop decryptor from Emsisoft
  • After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
    Click on decrypt_STOPDjvu.exe
  • If User Account Control (UAC) message shows up, press Yes.
  • Agree to License Terms by pressing Yes.
    Agree to License Terms
  • After Disclaimer shows up, press OK.
  • The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
    Add folders
  • Press Decrypt.
    Decrypt Djvu files

From here, there are three available outcomes:

  1. Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
  2. Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
  3. This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

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.

Report the incident to your local authorities

Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.

Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:

Internet Crime Complaint Center IC3

If your country is not listed above, you should contact the local police department or communications center.

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

  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 Jjtt and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
