The Taoy virus is a ransomware infection that belongs to the STOP/Djvu family. That malware family is famous for its file encryption capabilities. Once the Taoy virus infects a computer, it checks the disks for videos, photos, documents, and the like, and encrypts them. You can distinguish these files by the .taoy extensions at the end.
Taoy Virus Overview
Taoy
🤔 Taoy malware belongs to ransomware that originates from the DJVU/STOP ransomware family. Its primary purpose is to cipher all of your files it can reach. Then, the TAOY virus asks its victims for a ransom payment – ($490 – $980) in Bitcoin.
The Taoy virus is a malicious program that encrypts your files and demands payment for their recovery. This malware targets various file types and adds a distinct “.taoy” extension to the encrypted files. As a result, the files affected by this ransomware become inaccessible and unusable.
Subsequently, the ransomware demands a payment in Bitcoin from its victims, with the amount ranging from $490 to $980. Usually, the ransom instructions are provided in a text file named “_readme.txt“.
The Taoy Ransomware utilizes the Salsa20 encryption algorithm to scramble the contents of the targeted files. Due to the robust nature of this ciphering method, it is exceptionally challenging, if not impossible, to decrypt the files without the involvement of the attackers.
Upon completing the encryption process, the Taoy malware presents a ransom note to the victim, outlining the demand for payment in exchange for the decryption key. This note provides detailed instructions on how to make the payment and often includes threats of data loss or an increase in the ransom amount if the payment is not submitted within a specified timeframe.
I have created an all-encompassing list of potential solutions, tips, and approaches to disable the Taoy ransomware and decrypt and recover your files. There are situations when you can recover the files, while sometimes, it may be impossible.
📌 Important Note!
It is important to say that paying the ransom is not a guarantee of the successful files recovery. The crooks who stand behind the Taoy virus are not trustworthy. There were the cases where people have paid the ransom, only to be denied by the cybercriminals with the decryption key provision.
Taoy employs a unique key for every victim, with one exception:
- If Taoy fails to establish a connection with its command and control server (C&C Server) before starting the encryption process, it resorts to using offline keys. This key is the same for all users, allowing for the decryption of files encrypted by the ransomware.
The Taoy virus bears resemblance to other DJVU ransomware samples like Jaqw, Jasa, Jaoy, Yytw, Yyza, Tasa, and Poaz. This virus encrypts a wide range of common file types and appends its distinct “.taoy” extension to all files. For instance, a file named “1.jpg” would be altered to “1.jpg.taoy” and “2.png” to “2.png.taoy“.
After successful encryption, malware spawns a special text file named “_readme.txt” and places it in every folder containing the encrypted files. It also adds the readme file to the desktop, so the victim will not miss its appearance even without opening folders.
The image below provides a visual representation of files with the “taoy” extension:

This message asking payment is for restore files via decryption key:
_readme.txt (STOP/DJVU Ransomware) – The alarming alert requesting users to pay the ransom to decrypt the encrypted data contains these annoying admonitions.
The Taoy ransomware operates by executing a series of actions on a victim’s computer to carry out specific tasks. To begin with, it launches the winupdate.exe process, a misleading operation that displays a fake Windows update notification during the attack. This deceptive tactic aims to convince the victim that the sudden system slowdown is a result of a Windows update.
Concurrently, the ransomware initiates another process (named with four random characters) that scans the PC for targeted files and encrypts them. Subsequently, the ransomware eradicates Volume Shadow Copies from the system using the following CMD command:
vssadmin.exe Delete Shadows /All /Quiet
Once these copies are deleted, it becomes nearly impossible to restore the previous state of the computer using System Restore Points. The issue lies in the fact that ransomware operators eliminate any inherent Windows methods that could aid the victim in recovering files without charge. Furthermore, the hackers modify the Windows HOSTS file by appending a list of domains and associating them with the localhost IP address. Consequently, when the victim attempts to access one of the listed websites, a DNS_PROBE_FINISHED_NXDOMAIN error is encountered.
We have observed that the ransomware strives to restrict access to websites that offer various how-to guides for computer users. Clearly, by impeding access to specific domains, the malicious actors aim to prevent the victim from accessing pertinent and helpful information related to ransomware attacks online. The virus also places two .txt files on the victim’s computer containing details about the attack – the victim’s public key and personal ID. These files are named bowsakkdestx.txt and PersonalID.txt.
Even after implementing these changes, the malware doesn’t halt its activities. Variants of the STOP/DJVU ransomware often deploy the Vidar password-stealing Trojan on compromised systems. This threat boasts an extensive array of capabilities, including:
- Collecting sensitive data by executing malicious software on the victim’s computer.
- Gaining unauthorized access to login credentials for Steam, Telegram, and Skype accounts.
- Manipulating and viewing files on the victim’s computer discreetly.
- Stealing cryptocurrency wallets from the victim’s system.
- Granting the hackers remote control over the victim’s computer for various malicious activities.
- Extracting sensitive information such as browser cookies, saved passwords, and browsing history.
The cryptography algorithm used by DJVU/STOP virus is AES-256. So, if your data got encrypted with an online decryption key, the chances to get your files back without paying the ransom are quite low. Thing is, this key is unique for each victim, and picking it will take too much time.
Retrieving the online key in another way is also nearly impossible. It is stored on a command server owned by the hackers who spread the Taoy malware. For receiving decrypting code the payment should be $980. To get the payment details, the victims should contact the hackers by email (support@fishmail.top).
The message by the ransomware states the following information:
ATTENTION! Don't worry, you can return all your files! All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key. The only method of recovering files is to purchase decrypt tool and unique key for you. This software will decrypt all your encrypted files. What guarantees you have?

Do not pay the ransom!
Please, try to use the available backups, or Decrypter tool
The _readme.txt file also indicates that the computer user must initiate contact with the hackers’ representatives within 72 hours following the attack. If the user complies within this timeframe, the hackers offer a 50% discount, thereby reducing the ransom amount to $490.
However, it is strongly advised to refrain from paying the ransom! I highly recommend avoiding any communication with these fraudulent individuals and refraining from making any payment. A highly effective solution for recovering the lost data involves utilizing existing backups or employing the Decrypter tool provided by Emsisoft.
What sets all these viruses apart is the utilization of a similar series of steps for generating decryption keys. Consequently, unless the ransomware is still under development or harbors elusive vulnerabilities, manual recovery of the encrypted data is an unfeasible task. The only effective measure to safeguard your valuable data against loss is to consistently create backups of your crucial files.
Keep in mind that even if you maintain regular backups, they should be stored in a dedicated location separate from your primary workstation. For instance, you could store the backup on a USB flash drive or an external hard drive that is not constantly connected. Alternatively, you might consider leveraging online (cloud) storage solutions.
It goes without saying that if you store your backup data on your main device, it might become encrypted alongside your files. Therefore, storing the backup on your computer’s disk is certainly not a prudent choice.
How I was infected?
Ransomware has a various methods to built into your system. But it doesn’t really matter what way had place in your case.
Ransomware attack following a successful phishing attempt.
- Using online free hosting resources as a means to distribute the virus undetected.
- Disguising the virus installer alongside various apps, particularly those offered as freeware or shareware.
- Spreading the virus through spam emails containing deceptive links that lead to its installation.
- Obtaining pirated software from illegal peer-to-peer (P2P) resources, exposing users to potential malware threats.
Some incidents occurred when the Taoy virus was disguised as some legitimate procedure, for example, the messages demanding to install a browser update or a vastly needed codec for online media playback. This is usually the way how some online deceptions aim to force you into installing the ransomware manually, by actually making you directly involve in this process.
Surely, the fraudulent update alert will not indicate that you are going to actually inject the virus. This process will be disguised under some alert stating that you need to install an urgent security update or some dubious program whatsoever.
Undoubtedly, the software cracks represent the harm as well. Using P2P is both illegal and may end up with the injection of severe malware, including the Taoy ransomware.
To sum up, what can you do to prevent the penetration of the ransomware into your PC? Even though there is no 100% guarantee to thwart your PC from getting infected, there are certain tips I want to give you to avert the Taoy penetration. You must be vigilant while using free software today.
Verify you always read what the installer offers aside from the main free program. Stay away from opening dubious email attachments. Do not run files from the unknown recipients. Certainly, your current anti-malware software must always be updated.
The malware does not show itself openly. It will not be mentioned in the list of your available programs. Instead, it will be masked under some malevolent process running consistently in the background, that starts at the moment when you start your computer.

How to Restore .taoy Files?
In some case ransomware is not doom for your files…
The Taoy ransomware encryption mechanism algoritm is next: it ciphers every file byte-by-byte, then saves a file copy, removing (not overriding!) the initial file. Hence, the data of the file location on the disk drive is lost, but the original file is not erased from the drive. The cell, or the sector where this file was stored, can still contain this file, but it is not present in the file system and can be overwritten by data that has been loaded to this disk after the deletion. Hence, it is possible to retrieve your files using special software.
Anyway, after realizing it was an online algorithm, it is impossible to retrieve my encrypted files. I also had my backup drive plugged in at the time of the virus, and this was also infected, or so I thought. Every folder within my backup drive had been infected and was encrypted. However, despite losing some important files, I retrieved almost 80% of my 2TB storage.
When I started going through the folders, I noticed the readme.txt ransom note in every folder. I opened some of the folders and found that all files that were not in a subfolder within that folder had been encrypted. However, I found a flaw and glimmer of hope when I went into the subfolders in other folders and found that these files had not been encrypted. Every folder within my c and d drives, including subfolders, had been encrypted, but this was not the case with the backup drive. Having subfolders created within a folder has saved 80% of my data.
As I said, I believe this to be only a small loophole on a backup drive. I’ve since found a further 10 % of my data on another hard drive on a different pc. So my advice is if you use a backup drive, create subfolders. I was lucky, I guess. But I was also unlucky that the virus hit as I was transferring some files from my backup.
Hopefully, this can help some other people in my situation.
Jamie NewlandRecovering your files with PhotoRec
PhotoRec is an free program, which is originally created for data recovery from damaged disks, or for data recovery in case if they are unintentionally deleted. However, as time has gone by, this program adopted the ability to retrieve the files of 400 different extensions. Hence, it can be used for file restoration after the Taoy attack.
First, you need to download this app. It is 100% free, but the developer notifies that there is no warranty that your files will be restored. PhotoRec is distributed in a pack with another utility of the same developer – TestDisk. The resulting archive will have TestDisk name, but don’t worry. PhotoRec files are right inside.
To run PhotoRec, you need to find and open “qphotorec_win.exe” file. No installation process is required – the program has all the files it need inside of the archive, hence, you can mount it on your USB drive, and try to help your friends/parents/anyone who has been attacked by Taoy ransomware.
After the launch, you will witness the screen showing you the complete list of your disks. However, this details are likely futile, because the required menu is placed a bit higher. Click this tab, then choose the disk which was attacked by ransomware.
After choosing the disk, you need to choose the destination folder for the restored files. This menu is located at the lower part of the PhotoRec window. The best selection is to export them on USB drive or any other type of removable disk.
Then, you need to specify the file formats. This choice is located at the bottom, too. As it was mentioned, PhotoRec can recover the files of about 400 different formats.
Finally, you can begin files restoration by pressing the “Search” button. You will observe the screen where the findings of the scan and recovery are shown.

Frequently Asked Questions
No way. These files are encrypted by ransomware. The contents of encrypted files are not available until they are decrypted.
If your data remained in the .taoy files are very valuable, then most likely you made a backup copy.
If not, then you can try to restore them through the system function – Restore Point.
All other methods will require patience.
Of course not. Your encrypted files do not pose a threat to the computer. What happened has already happened.
You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.
In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.
Have patience. You are infected with the new version of STOP/DJVU ransomware, and decryption keys have not yet been released. Follow the news on our website.
We will keep you posted on when new keys or new decryption programs appear.
The Taoy ransomware encrypts only the first 150KB of files. So MP3 files are rather large, some media players (Winamp for example) may be able to play the files, but – the first 3-5 seconds (the encrypted portion) will be missing.
You can try to find a copy of an original file that was encrypted:
- Files you downloaded from the Internet that were encrypted and you can download again to get the original.
- Pictures that you shared with family and friends that they can just send back to you.
- Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc
- Attachments in emails you sent or received and saved.
- Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.
