ExilenceTG ransomware (virus) - Recovery Instructions Included

ExilenceTG virus Removal Guide

What is ExilenceTG ransomware?

ExilenceTG ransomware is a dangerous virus that locks users' personal files

ExilenceTG ransomwareRansomware infections can result in data loss if there are no backups

ExilenceTG ransomware is a file-locking virus that infiltrates the system and encrypts users' personal files. It is a variant of Key Group ransomware and uses complicated encryption[1] algorithms to lock photos, videos, documents, and other personal data. When the process is finished, victims cannot open or use their data.

It also appends the .exilenceTG extension to the affected files. The icons become white pages, obscuring the thumbnails. Threat actors then create a ransom note called cyber.txt, in which they inform victims about what has happened to their files and change the wallpaper image.

NAME ExilenceTG
TYPE Ransomware, cryptovirus, data-locking malware
DISTRIBUTION Email attachments, peer-to-peer file-sharing platforms, malicious ads
FILE EXTENSION .exilenceTG
RANSOM NOTE cyber.txt
FILE RECOVERY If no backups are available, recovering data is almost impossible. We list alternative methods that could help you in some cases below
MALWARE REMOVAL Scan your machine with anti-malware software to eliminate the malicious files (this will not recover your data)
SYSTEM FIX Malware can seriously tamper with Windows systems, causing errors, crashes, lag, and other stability issues. To remediate the OS and avoid its reinstallation, we recommend scanning it with the FortectIntego repair tool

The ransom note

ExilenceTG ransomware drops a ransom note named cyber.txt:

YOUR SYSTEM IS LOCKED AND ALL YOUR IMPORTANT DATA HAS BEEN ENCRYPTED.
DON'T WORRY YOUR FILES ARE SAFE.
To return them, write to telegram: @exilenceTG Email/ 534411644559@ngs.ru
greetings from keygroup777
your files were encrypted with military algorithms:)
our allies and friends:
employees of our program/company:
abuse@telegram.org
dmca@telegram.org
recover@telegram.org
security@telegram.org
sms@telegram.org
sticker@telegram.org
stopCA@telegram.org
support@telegram.org

This ransom note informs the victim that their system has been locked and all sensitive data has been encrypted using military algorithms. However, the note assures the victim that their files are safe, and the victim is instructed to contact the sender via Telegram or email if they want them returned. The note concludes with “greetings from keygroup777” and includes a list of email addresses for various Telegram departments.

Victims should not pay the ransom demanded in this note because there is no guarantee that even after payment, the attacker will provide the decryption key or return the victim's files. Furthermore, paying the ransom encourages the attacker to carry on with their criminal activities, putting other potential victims in danger.

It is advised that victims seek the assistance of cybersecurity professionals in order to recover their files and restore the security of their systems. Victims should also notify law enforcement in order to help prevent future attacks.

Distribution methods

Although it is unknown how ExilenceTG ransomware is distributed on the Internet, threat actors use some general tactics to distribute malicious programs. During “cracked” software[2] installations, malicious files can infiltrate the system. Avoid using torrent websites[3] and peer-to-peer file-sharing platforms because they are ideal breeding grounds for malware.

Email can also be used by cybercriminals to deliver ransomware into your system. This is accomplished by including malicious links or attachments in the email. It is not recommended to open emails from unknown senders. Even if you received an attachment from a friend, it is best to double-check with them via another platform.

Hackers may also use OS or software vulnerabilities as a distribution channel. That is why it is critical to keep everything current. Software developers release security patches for newly discovered vulnerabilities on a regular basis, so you should install them as soon as they are available.

Start the removal process

The critical step is to disconnect the affected machine from the local network. Disconnecting the ethernet cable should suffice for home users. If this occurred at your workplace, doing so may be difficult; therefore, we have instructions for corporate environments at the bottom of this post.

Attempting to recover your data first may result in permanent loss. It also has the ability to encrypt your files a second time. It will not stop until you remove the malicious files that are causing it. Unless you have prior experience, you should not attempt to remove the malicious program yourself. Manual removal of ransomware is extremely difficult and should only be attempted by people with advanced IT skills.

Use anti-malware tools like SpyHunter 5Combo Cleaner or Malwarebytes to scan your system. This security software should find all the related files and entries and remove them automatically for you. In some cases, malware does not let you use antivirus in normal mode, so you need to access Safe Mode and perform a full system scan from there:

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 XP/7

Windows 10 / Windows 8

  1. Right-click on Start button and select Settings.
  2. Scroll down to pick Update & Security.Update & Security
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find Advanced Startup section.
  5. Click Restart now.Recovery
  6. Select Troubleshoot.Choose an option
  7. Go to Advanced options.
  8. Select Startup Settings.
  9. Click Restart.
  10. Press 5 or click 5) Enable Safe Mode with Networking.Press F5 to enable Safe Mode with Networking

Repair corrupted system files

Performance, stability, and usability issues that necessitate a full Windows reinstall are not uncommon after malware infection. These viruses can change the Windows registry database, harm vital bootup and other sections, delete or corrupt DLL files, and so on. When malware corrupts a system file, antivirus software cannot repair it.

Manual troubleshooting of such damage is also very complicated and can take a long time. This is why FortectIntego was developed. It can fix a lot of the damage caused by an infection like this. Blue Screen errors, freezes, registry errors, damaged DLLs, etc., can make your computer completely unusable. By using this maintenance tool, you could prevent yourself from having to reinstall Windows completely.

  • Download the application by clicking on the link above
  • Click on the ReimageRepair.exe
  • 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

Try recovering data with third-party software

Only hackers have the decryption key that can unlock your files, so if you did not back them up previously, you may never get them back. You can try data recovery software, but keep in mind that third-party programs are not always capable of decrypting files. Whatever the case may be, we recommend at least trying this method. Before you continue, copy the corrupted files to a USB flash drive or another external storage device. Remember, only do this if the ExilenceTG ransomware has already been removed.

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.
  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

Getting rid of ExilenceTG virus. Follow these steps

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.

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.

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.

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.
