How ONIX ransomware behaves

From our report of Feb 2020 · not reviewed since

ONIX ransomware - a malware form that comes from Major ransomware and adds the .ONIX appendix next to each filename after the encryption process

ONIX ransomware is a virtual parasite that has been discovered to come from Major ransomware family.

The first to announce about this ransomware infection on Twitter was a computer security researcher named Amigo-A. The dangerous malware enters Windows computer systems unknowingly and aims to lock up all the documents and files that are placed on the device by marking all of them with the .ONIX appendix.

For the encryption, ONIX ransomware employs ciphers such as AES, RSA, or SHA which hold specific codes that differ for each infected computer.

Right after that, the ransomware virus provides ransom demands via TRY_TO_READ.html message and also changes the desktop's background to the ransom note. The messages warn users not to try to unlock files by themselves as this can relate in permanent data loss.

However, the main goal of ONIX ransomware is to encourage users to write via Ad_finem@tutanota.com, adfinem001@cock.li, and Ad_finem001@protonmail.com email addresses and discuss all the ransom price matters with the cybercriminals.

ONIX ransomware is a dangerous malware string that has been detected as a virus by 58 antivirus engines out of the total 71. According to VirusTotal information, some of the detection names include ML.Attribute.HighConfidence, Win32:Trojan-gen, Gen:Heur.Ransom.Imps.1 (B), A Variant Of Win32/Filecoder.NSN, Ransom:Win32/Crowti.P!MSR, and others.

ONIX virus uses stealth distribution techniques for appearing on the targeted computer system. This malware infects Windows operating systems only and looks for people who are using the English language. This is also the language in which the TRY_TO_READ.html ransom message is written in:

ONIX ransomware manipulates locations such as the Windows Registry and Task Manager in order to fill these areas with malicious processes and keys. All of these tasks are planted to help the malware to operate smoother and reach its goals.

For example, ONIX ransomware might disable your antivirus protection to avoid getting detected and to stay in your computer system for a longer period of time. This way the program could prevent some particular software from deleting the malware itself and all the malicious components that it has brought to the computer system.

Furthermore, ONIX ransomware includes some type of an executable to the Windows computer that scans the entire device for encryptable files and documents. This happens in certain periods of time, for example, half an hour, an hour, and so on in order to make sure that all components were properly locked by the malware.

When ONIX ransomware applies the .ONIX encryption appendix to all of the files and documents found, the content gets locked and cannot be opened properly anymore. The only way to reverse the data back to its previous position is to get the decryption tool that would work. However, we suggest denying the option of buying the tool from the cybercriminals as these people might ask for inadequate amounts of money.

ONIX ransomware developers do not provide any particular information about the ransom demands, however, all of the conditions are likely to be discussed via email. You might not even notice how they will scam you and run off with your money.

Most of the time, malicious actors are likely to urge large amounts of money starting anywhere from $100 and ending up with $2500 or even more. Always be careful with demands that come from malware such as ONIX ransomware and overthink everything twice before deciding whether the price is worth to pay or not.

Keep in mind that you are likely to be asked for cryptocurrency transfers by ONIX ransomware such as Bitcoin. These types of payments allow the cybercriminals to stay untrackable and anonymous so no one could discover the transactions.

ONIX ransomware might try to harden the data recovery process for the victims by running the vssadmin.exe delete shadows /all /Quiet command via PowerShell. This way the malware will erase the Shadow Copies of all of the encrypted data and the users will not be able to employ software that could restore at least some of the locked files with the help of the deleted Shadow Copies.

To add, ONIX ransomware might target the Windows hosts file and aim to totally wreck them for their own purposes. This way the virus seeks to prevent the victim from accessing security-related networks, websites, and forums, where he/she could get reliable information on the malware removal process and data recovery task.

Furthermore, ONIX ransomware acts as a backdoor for other malware forms. The ransom-demanding threat makes the Windows computer vulnerable to other infections and increases the risk of getting attacked by dangerous virtual parasites such as Trojan viruses, spyware, worms, and others.

ONIX ransomware removal is the first step you should take the same minute you find the ransomware virus operating on your computer system. Keep in mind that you should not try to eliminate the cyber threat on your own as you can make damaging mistakes and hurt your computer system even more.

When you remove ONIX ransomware and all the bogus products that the malware has brought with the help of antimalware software, you should start looking for possible damage that might have been performed on your Windows computer. If you discover any affected areas, try repairing them with the help of software such as .

Note that you need to uninstall ONIX ransomware before you start taking any data recovery steps, otherwise, all of your files will be encrypted again. If you have terminated the cyber threat properly, you can start opting for file restoring solutions some of which we have provided at the end of this article.

Different techniques used for ransomware distribution

Cybersecurity experts from NoVirus.uk state that ransomware-related payload gets onto Windows computer systems through email spam and the malicious attachments that come clipped to the suspicious messages.

Crooks pretend to be from reliable healthcare, shipping, or banking companies.

You should not open any attached component without scanning it with antimalware software. Also, if the email message has a hyperlink included, you should not enter it if the content of the email and the sender looks suspicious to you. Things to search for:

Furthermore, ransomware infections can be pushed through malicious adverts that are also known as malvertising. The same can happen with hyperlinks that have a tendency to appear on third-party networks. The main thing to do here is to avoid entering suspicious-looking websites and closing all bogus pages that appear.

To add, ransomware viruses can get distributed through software cracks that are placed in peer-to-peer networks such as The Pirate Bay. Regarding this fact, use only reliable downloading sources for getting your wanted products and services.

Also, malicious actors search for vulnerable RDP configuration (one that includes weak passwords or none at all) and hack the port or brute force the password into the system and connect to the computer remotely. So, make sure that you always think of strong and reliable passwords that include some symbols, letters, and numbers.

  • A bogus sender email address such as repaircomputer@cock.li.
  • The content is filled with grammar mistakes.
  • You have received an email from a non-existing company.

How to remove ONIX 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 ONIX 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

    Unplug the network cable or turn off Wi-Fi, and disconnect USB drives, external disks and network shares, so ONIX ransomware cannot reach more files. Pause OneDrive, Google Drive or Dropbox sync, because synced folders upload the encrypted copies over the good ones.

    Leave the PC on but offline while you read the next steps, since a restart can let the ransomware run again. This applies to Windows 11 and Windows 10 alike.

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

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

    Your files now end in .onix and the instructions are in TRY_TO_READ.html. Save both to a USB stick, a copy of the note and two small encrypted files, before anything else.

    On another device, check them with ID Ransomware or Crypto Sheriff: the family name decides which decryptor, if any, can help. Keep the note's ID and contact line for your report.

  3. Step 3: Check for a free decryptor

    Our last check found that for ONIX ransomware, no free decryptor is known (checked 6 October 2026). Look again yourself in the No More Ransom list and the free decryptor pages of Emsisoft, Avast and Kaspersky, which add new families every year.

    A decryptor needs the ransomware gone first, or it encrypts the files again. Keep at least one copy of the encrypted files on an external drive, even if no tool works yet.

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

    Removing ONIX ransomware does not bring the files back, but it has to come first. Start with Defender's Full scan, then the offline scan from the same Scan options page, which checks the disk before Windows loads.

    If the scan cannot start, use Safe Mode with Networking. Delete the ransom notes only after you have saved a copy, because removal tools sometimes leave them behind on Windows 11 and 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

    Windows keeps shadow copies for restore points and backups, and some ransomware fails to delete them. vssadmin list shadows in an administrator Command Prompt tells you at once whether any exist.

    If they do, right-click the folder that held your files, open Properties > Previous Versions, select a version from before the attack, and click Open to check it before you Restore or copy the files out. Windows 11 and Windows 10 both have the tab.

    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

    A backup made before the attack is the surest way back. Connect it only once the PC is clean, then restore from File History, Windows Backup, OneDrive's Restore your OneDrive or your own external copies.

    Without a backup, try file recovery: the originals that ONIX ransomware deleted may still be on the disk until something overwrites them. Install nothing new on the drive you want to recover from on the Windows 11 or Windows 10 PC.

Know about ONIX ransomware removal possibilities

If you are looking for ways to remove ONIX ransomware from your Windows machine, you have come to the right place.

Our security experts claim that you should not try to eliminate the malware on your own as you might skip some malicious components and accidentally leave them on the computer system.

ONIX ransomware removal should be completed with the help of reliable antimalware software that is capable of detecting and eliminating the ransomware virus from your device. Afterward, scan the entire system for possible damage with or . If these tools find any compromised areas, you can try repairing them with .

When you uninstall ONIX ransomware properly, it is time to start thinking about data recovery possibilities. Rather than taking risks to get scammed and paying the cybercriminals, you should try some other file restoring alternatives like the ones that we have provided at the end of this article.

Keep in mind that if ONIX ransomware has damaged your Windows hosts files, these components need to be eliminated too, otherwise, access to cybersecurity websites might still remain blocked even if the ransomware virus is no longer active.

[GI=method-1]To deactivate malicious settings on your Windows computer system and reverse the device back to how it was before the ransomware attack, you should follow the below-provided steps and boot your machine in Safe Mode with Networking.

[GI=method-2]To disable the malware on your device and get rid of all malicious processes that were brought by the ransomware virus, use the following instructions and activate the System Restore feature.

If you have been looking for a tool that would help you to recover the files and documents that were encrypted by the ransomware virus, you can try employing this piece of software.

Windows Previous Versions feature might be helpful software for file restore.

If you have enabled the System Restore function on your Windows computer, you can give this tool a try.

Shadow Explorer might be able to recover some data.

You can try using this piece of software for restoring at least some of your files. However, keep in mind that this tool might not work if the ransomware virus has eliminated or permanently damaged the Shadow Volume Copies of your locked data.

Cybersecurity experts are currently working on the .ONIX files decryption tool.

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.

Make the next attack harmless

ONIX ransomware could only hurt the files that had no second copy, and the signs (files that end in .onix and no longer open) showed exactly which ones those were.

The 3-2-1 rule fixes that:

  • three copies
  • two media
  • one disconnected

A practical version for a home PC: OneDrive or another cloud backup with version history, plus an external disk that you plug in once a week for File History and then unplug. Test a restore now and then by opening a few files from the backup on another device.

Details, schedules and what not to back up are in our 3-2-1 backup guide for Windows.

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 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
  • 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, can be your only hope to retrieve your invaluable files.

Questions about ONIX ransomware

How do I open .onix files?

You cannot open them by renaming or with another program, because the content of files ending in .onix has been encrypted. The only ways back are a working decryptor for the family, or clean copies from elsewhere:

  • OneDrive versions
  • File History
  • an offline backup drive
  • Previous Versions if the ransomware did not delete them

Identify the family first by uploading the ransom note and one encrypted file to ID Ransomware or No More Ransom. Avoid websites and programs that promise to open any encrypted file; they do not work and some are scams.

Should I pay the ransom in TRY_TO_READ.html?

Not before you have tried everything else. Identify the family from TRY_TO_READ.html and one encrypted file, check No More Ransom for a free decryptor, and look for clean copies in OneDrive, backups and Previous Versions.

Paying funds further attacks, may be illegal if the group is sanctioned, and is no promise of a working key: many victims get partial or broken decryption. If you consider paying for business-critical data, involve the police and a professional incident responder first, and never pay through intermediaries who promise their own decryption.

How did ONIX ransomware get on my computer?

The way ONIX 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 .onix 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.

Is there a free ONIX ransomware decryptor?

We last checked on 6 October 2026, and for ONIX ransomware no free decryptor is known. We check No More Ransom, which collects free tools from police and security companies, and the decryptor pages of the major antivirus vendors. A working decryptor exists only when the encryption has a flaw or the keys were leaked or seized.

Ignore sites and videos that offer a "ONIX ransomware decryptor" for download or for a fee: these are usually scams or malware. Real decryptors are free and come from known security companies or law enforcement. Keep the encrypted files in case a tool appears later.

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.

Did ONIX ransomware steal my files or passwords?

We do not know yet. Nothing published so far shows data theft by ONIX ransomware, but the only confirmed sign is files that end in .onix 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 ONIX 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.

Can I delete TRY_TO_READ.html?

Yes, the note itself is harmless text and deleting it does not affect your files. Keep at least one copy first, outside the infected PC. TRY_TO_READ.html contains your personal ID and the attackers' contact details, which identification services use to tell which family encrypted your files, and which a decryptor may need later.

Police reports also ask for it. Once you have saved a copy, you can remove the notes from every folder after the ransomware program has been removed and your files are restored or backed up.

Defender removed Ransom:Win32/Crowti.P!MSR. Am I safe now?

Often yes, but check two things. First, whether the detection was caught on arrival: a file in Downloads or in an archive that Defender quarantined before it ran is the best case.

Second, whether Ransom:Win32/Crowti.P!MSR comes back. If it returns, or if Protection history shows several different detections around the same date, something on the PC keeps producing the file and needs to be found.

Run a full scan and, if anything remains, an offline scan. If the category names a password stealer or a backdoor, change your passwords from another device even if the file is gone.

Will Fortect remove ONIX 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 ONIX 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.
