How Un1que ransomware behaves

From our report of Feb 2020 · not reviewed since

Un1que ransomware is the file-locking virus that derives from another famous malware family – IEncrypt ransomware

Un1que ransomware is the cryptovirus that uses a popular strategy to target large companies and businesses.

This is a typical target for the IEncrypt ransomware virus versions because the bigger the victim the bigger the ransom amount can be. But this particular version shows that everyday users can still get affected by such threats. Ransomware infects the machine and starts the encryption process immediately, so files chosen for the process can get affected as soon as possible.

Once that is done, each image, document, video, or audio file receives the .un1que file marker that distinguishes encrypted files from non-affected data. However, such infections, in most cases, encode tons of personal data and leave only system files un-encrypted.

Nevertheless, the Un1que ransomware virus damages such files with additional processes that get to be launched in the background. It manages to affect particular security functions, features that could be helpful for data recovery or virus removal. This threat can install programs, disable the ones that already run on the machine, or install secondary malware payload on the already infected system, so it damages even more than the encryption does.

Even though previous versions of the same family only targeted companies and businesses, Un1que ransomware appears to also spread on the systems of simple users. The main target still remains companies al over the globe. Once it gets on the system and those photos, documents, videos, databases, and other files get encrypted, the ransom message file appears on the desktop and in some of the folders with encoded data.

Un1que ransomware virus developers write their message in un1que_readme.txt file that contains particular contact emails and claims that there are no other options besides paying for the alleged decryption tool. To determine the particular ransom amount and receive further instructions, people need to contact those criminals as soon as possible until those files haven't gotten permanently damaged.

Typical Un1que ransom note:

When people contact Un1que ransomware developers they need to indicate the name of their company and the particular key included in the ransom note. This ID is unique per each target and determines the victim for developers. This unique victims' key is needed for the decryption too when researchers develop such tools or when the ransom gets paid, and the victim receives a tool capable of recovering those files.

However, no one that knows about cryptocurrency extortion-based viruses can offer to pay for these criminals behind the dangerous Un1que ransomware virus. Experts in various countries claim that there is no reason to pay the demand because criminals cannot guarantee that the decryption tool is going to reach you after that.

In most cases, even large governments and companies stay away from such options. The best option when dealing with ransomware is to get an anti-malware tool and run a proper Un1que ransomware removal process. Especially, when it is known that many AV engines can detect this threat and other related programs associated with the same family.

An important thing to note is the issue of detection names. You can see that many of the engines find safe malware malicious but indicates specific names. This is due to unique databases of threats, so rely on results and malicious detection, not the specific name:

You need to remove Un1que ransomware regardless of the particular name. The best way to remove the threat like this is to get a professional anti-malware program. This is a powerful malware that targets large networks of businesses, so it can be persistent enough to avoid detection and security tools. Make sure to choose an official source for the tool if you decide to get a new program.

You should reboot the machine in a Safe Mode before you run the anti-malware tool on the machine to eliminate Un1que ransomware. This way, malware can be found easier and deleted from the computer fully. Also, remember about all the changes threat makes on the system and get proper repair tools like that could find and fix affected files and repair things like registry entries.

Since Un1que ransomware interacts with the system and damages such functions like file or system recovery or startup, you need to take the settings back to normal, so the virus is no longer accessing removable storage devices or network shares and cannot create additional processes or install programs.

As for file recovery, the best option is to get files from backups on external devices or cloud services. This is how you can replace encoded files with safe ones without causing additional damage. If you don't have that option - read below the article.

Terminate the Un1que cryptovirus and repair the damage

Un1que ransomware removal is not the process that could be achieved manually and quickly.

Remember that this malware includes modules that allow the virus to keep persistent on the infected machine and avoid detections bu injecting existing processes with malicious codes and creating additional entries in registry or memory.

There are a few additional things about Un1que ransomware virus that should be indicated: malware can load data-stealers on the system, and obtain information about the device, steal other files with personal and useful information. Since this threat can get on the network of a company, such devices may store crucial information.

Make sure to remove Un1que ransomware before it is too late, and the threat hasn't loaded secondary payloads or malware on the machine. This is how you avoid permanent damage. Rely on security and system tools like , , or and clean the machine fully before recovering data.

[GI=method-1]Reboot the machine in Safe Mode with Networking and then run the AV tool to delete Un1que ransomware from the system

[GI=method-2]System Restore feature is helpful for Un1que ransomware removal because it can restore the machine in a previous state when the virus was not active yet

Windows Previous Versions is the method allowing the file recovery after Un1que ransomware virus attack

When you enable System Restore, you can choose Windows Previous Versions as a method for file restoring

ShadowExplorer is the feature of an operating system that allows users to restore encoded files

Social engineering strategies included in ransomware spreading campaigns

Email messages and hacker-controlled sites get employed for spreading the payload of cryptovirus globally.

This is how threat actors can target companies and businesses at the same time as everyday users - everyone receives emails. Visitors get confused into thinking that the message is legitimate and sent from an institution or company.

Emails include either link to a malicious website where the payload is triggered and dropped after interaction with the content or the file directly attached to the email itself, so the person needs to download the document and open it on the machine. Then additional pop-up encourages the victim to enable malicious macros or different payload dropper.

Infected files with ransomware payload also get uploaded in packages with pirated software on torrent sites and file-sharing services. You cannot notice the infection this way, especially when you choose wrong installation methods that allow every application or file included to get loaded on the system.

Pay attention to emails you receive, look for red flags, do not trust ransom senders. Also, rely on proper software providers, do not pirate or download cheats, cracks of games or software. This is the only way to avoid malware. As for companies and businesses - data backups and secure networks should be a priority.

How to remove Un1que ransomware

Tools you'll need

All of these are free except where noted. Download them on a clean device if the infected PC is offline.

  • A USB stick: to keep the ransom note, two or three encrypted files and screenshots off the infected PC.
  • Microsoft Defender Offline: built into Windows 11 and Windows 10; scans before Windows starts, so running malware cannot hide.
  • Microsoft Safety Scanner: a second, portable scanner with current signatures; each download works for 10 days.
  • ID Ransomware: identifies the family from the note and one encrypted file and says whether a decryptor exists.
  • No More Ransom: the free decryptors from police and security companies; check it again every few months.
  • Fortect (optional): scans Windows for malware and repairs the system files and settings it damaged. The free scan is in the box above.

How to remove Un1que ransomware and get your files back

Work in this order.

Disconnecting comes first, removal comes before any restore, and nothing here asks you to contact the attackers.

  1. Step 1: Disconnect the PC and unplug backup drives

    Un1que ransomware encrypts everything it can reach, including drives and shares you connect later. Cut the network first: cable out, or Wi-Fi off from the taskbar.

    Then unplug every USB stick and backup disk and pause cloud sync, so the encrypted versions do not replace your online copies. Do not reconnect any of them until the ransomware is removed from the Windows 11 or Windows 10 PC.

    Windows 11: turn off Wi-Fi to take the PC offline.

  2. Step 2: Save the ransom note and confirm the family

    Copy un1que_readme.txt and one or two files ending in .un1que to a USB stick, and leave the originals where they are.

    From another device, upload the note and a sample file to ID Ransomware or No More Ransom's Crypto Sheriff, which name the family from the note, the extension and the file structure.

    Write down the contact address and your personal ID from the note, because a decryptor or the police may ask for them.

    Warning: Never contact the attackers from the infected Windows 11 or Windows 10 PC.

  3. Step 3: Check for a free decryptor

    For Un1que ransomware, no free decryptor is known (checked 6 October 2026). Search the family name in the No More Ransom decryption tools list and in the free decryptors of Emsisoft, Avast and Kaspersky, because new tools appear years after an attack.

    Important: Keep the encrypted files even if nothing works today, and do not pay before every free option is ruled out: payment does not guarantee a working key.

    Decryptors run on Windows 11 and Windows 10, but only after the ransomware itself is removed.

  4. Step 4: Remove the ransomware before you restore or decrypt

    Restoring or decrypting files while Un1que ransomware still runs lets it encrypt them again. Run a Full scan in Windows Security > Virus & threat protection > Scan options, then the Microsoft Defender Antivirus (offline scan).

    If the ransomware blocks Windows Security, start Safe Mode with Networking and scan from there. Some families install a password stealer as well, so let both scans finish on Windows 11 or Windows 10.

    Windows 11: Windows Security > Virus & threat protection > Scan options.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

  5. Step 5: Look for shadow copies of the files

    Open Command Prompt as administrator and run vssadmin list shadows. If it lists copies dated before the attack, right-click a folder with encrypted files in File Explorer, choose Properties > Previous Versions, and open or restore a version from before that date.

    ShadowExplorer, a free tool, shows the same copies when the tab is empty or hidden. Most current families delete shadow copies, so an empty list is normal, but the check takes two minutes on Windows 11 or Windows 10.

    Command Prompt running vssadmin list shadows
    Windows 11: vssadmin list shadows shows whether shadow copies exist.

  6. Step 6: Restore the files from a backup or recover deleted originals

    Restore from an external backup, File History or OneDrive's version history, choosing a date before the attack. Connect the backup drive only after the scans are clean, or the ransomware encrypts it too.

    If there is no backup, file recovery software can sometimes find the deleted originals, because some ransomware writes an encrypted copy and deletes the original file.

    Stop writing to the drive and try recovery on Windows 11 or Windows 10 before new files overwrite the space.

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.

  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.

Report it and recover your files

Report it

Report the attack even if you do not expect the files back: insurers and banks ask for the report number, and police use the contacts in the note to link cases.

United States
FBI IC3 · FTC ReportFraud

Give the victim ID, the note and the date the files were encrypted. A business that holds personal data may also have to notify its data protection authority, in the EU within 72 hours.

Protect the files you restore

Restore only after the scans are clean and the PC no longer shows files that end in .un1que and no longer open; otherwise the restored copies can be damaged again.

Then build a backup that survives the next infection:

  • one copy in the cloud with version history
  • one on an external drive that is disconnected between backups
  • the working copy on the PC

Version history matters because a backup that syncs damaged files overwrites the good ones.

How to do this with the tools built into Windows: the 3-2-1 backup rule on Windows.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity.

While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important - recover your lost files

Ransomware is one of the biggest threats to personal data.

Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as can also be effective and restore at least some of your lost data.

Questions about Un1que ransomware

Is there a decryptor for .un1que files?

That depends on the family behind the .un1que extension, which this guide cannot confirm yet from the reports alone. Check No More Ransom and ID Ransomware with your ransom note and one encrypted file; they list families with free tools.

If none exists today, keep the encrypted files and a copy of the note on a separate drive, because decryptors are sometimes published months later after flaws are found or servers are seized. Never buy a decryptor from a website that is not the security company that made it.

How do I open .un1que files?

You cannot open them by renaming or by choosing another program. The .un1que ending shows that Un1que ransomware encrypted the content, and only the matching key can reverse it. Renaming a file back to .docx or .jpg changes nothing except the icon, and it can confuse a future decryptor, so leave the names as they are.

To get the content back, use a backup, an unencrypted copy elsewhere, or a decryptor listed on No More Ransom if one exists for Un1que ransomware. Store the encrypted files on an external disk until then.

Can a data-recovery company decrypt my files for a fee?

Only if a decryptor already exists or the company pays the attackers for you. Some "ransomware recovery" services advertise that they can decrypt families with no known flaw; in practice they negotiate with the attackers and add their own fee. Others use the same free tools listed on No More Ransom.

Before you hire anyone, ask in writing how they will recover the files, whether they will contact the attackers and what happens if they fail. A legitimate service answers clearly. If a free decryptor exists for your family, you can run it yourself.

Should I pay the ransom?

We advise against it, and so do the FBI, Europol and national cyber agencies. Payment does not guarantee a working tool: some attackers never reply, some tools damage files, and some variants have no decryptor at all. Paying also funds further attacks and can make you a target again.

Before considering payment, try every recovery option in this guide and report the attack. Companies must involve their legal adviser and insurer, because payments to sanctioned groups can be illegal. If files are truly irreplaceable, store the encrypted copies and wait; decryptors sometimes appear later.

How did Un1que ransomware get on my computer?

The way Un1que ransomware spreads has not been documented yet, so look at your own recent activity. On home PCs, ransomware most often comes with cracked programs, game cheats, key generators and fake updates, or with an e-mail attachment that was opened. On business networks, attackers usually log in through Remote Desktop with a stolen or guessed password.

Think back to what was downloaded or installed in the days before files that end in .un1que and no longer open, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.

Did Un1que ransomware steal my files or passwords?

We do not know yet. Nothing published so far shows data theft by Un1que ransomware, but the only confirmed sign is files that end in .un1que and no longer open, which says nothing about what happened before. Many current ransomware attacks copy files or run a password stealer first, so it is wise to act as if they did.

From a clean device, change the passwords that were saved in the browsers on this PC, starting with e-mail and banking, sign out of all sessions and turn on two-step verification. Watch bank statements and account activity for the next few weeks.

Is Un1que ransomware the same as other ransomware with a similar name?

Not necessarily. Ransomware names come from the file extension, the note or a word in the code, so unrelated families often end up with similar names, and one family can appear under several names. The difference matters: a decryptor or advice for one family does not fit another and can damage files.

Compare the ending added to your files and the exact name of the note with the summary table at the top of this guide, then upload the note and one encrypted file to ID Ransomware from a clean device. If the result names another family, follow the guide for that family instead.

What does un1que_readme.txt tell me about the ransomware?

Quite a lot. The file name un1que_readme.txt, the wording, the contact addresses and the format of the personal ID are typical for each family. Uploading the note together with one encrypted file to ID Ransomware or No More Ransom's Crypto Sheriff usually names the family within seconds.

That name decides your options: some families have free decryptors, some can be partially recovered, and some cannot be decrypted at all. The note's claims about stolen data should be taken seriously but not at face value.

Should I reinstall Windows after the .un1que attack?

Reinstalling removes the ransomware but not the encryption: your files ending in .un1que stay encrypted afterwards. So first copy the encrypted files and the ransom note to a separate drive, in case a decryptor appears later. Then decide:

  • a clean-up with an offline scan is often enough for home PCs
  • while a full reset is safer if remote access was involved
  • scans keep finding new items

Restore your backups only after the PC is clean, and change passwords from another device.

Will Fortect remove Un1que ransomware?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For Un1que ransomware, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
