What is Rryy virus?
Rryy virus is a new ransomware that attacks the victim’s computer by encrypting files and demanding a ransom for decrypting them. The ransomware attack can lead to data loss and financial losses. Rryy encrypts files, renames them by appending the .rryy extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “document.docx” will be renamed to “document.docx.rryy”, a “image.jpg” file to “image.jpg.rryy”, “invoice.pdf” to “invoice.pdf.rryy”, and so on.

Rryy ransomware is a malware that is the 493th variant of STOP (DJVU) ransomware. Like other variants of this ransomware, it is distributed through Windows/Office activators, hacked software, adware and torrents web-sites. Upon execution, Rryy creates a folder in the Windows system directory and copies itself there. Then the virus collects information about the victim’s computer and changes some Windows OS settings so that it starts automatically every time the PC is turned on or restarted.
Having collected information about the victim’s computer, the Rryy ransomware tries to establish a connection with its command-and-control server (C&C). If the connection has been established, the virus receives a key (so called ‘online key’) from the command server that will be used to encrypt files. In addition, Rryy virus may receive additional commands and files that will be executed on the victim’s computer. If the ransomware could not connect to the command server, then it uses a fixed key, which the security researchers called ‘offline key’.
There is a significant difference between ‘online key’ and ‘offline key’. The online key is unique for each victim, that is, the key from one victim will not help decrypt the files of the other victim. The offline key is the same for all victims. Thus, it can be used to decrypt files regardless of where they were encrypted.
Having a key to encrypt files, the Rryy ransomware proceeds directly to the process of encrypting files. It encrypts file-by-file, so that all files of the victim will be encrypted. It doesn’t matter where the files are located, on the internal drive, flash drive, external media, cloud storage, all of them can be encrypted. There is a small exception, the virus does not encrypt files located in the Windows system directories, files with the extension from the list ‘.lnk, .bat, ini, .sys, .dll’ and files with the name ‘_readme.txt’. Thus, almost all of the victim’s data will be encrypted, including documents, pictures, databases, archives and other types of files, such as:
.rtf, .mddata, .ncf, .iwi, .x3f, .7z, .ff, .pef, .odc, .upk, .xpm, .png, .sql, .crt, .snx, wallet, .wpt, .x, .apk, .layout, .dba, .xf, .xwp, .lrf, .doc, .xls, .psk, .xmind, .desc, .xdb, .odb, .ptx, .arw, .arch00, .ysp, .pptm, .eps, .cer, .wbk, .dxg, .qdf, .itm, .wpa, .z, .raw, .crw, .der, .wmd, .blob, .xls, .xyw, .zif, .big, .odp, .rw2, .dng, .w3x, .vpk, .xmmap, .wpl, .asset, .wps, .lvl, .2bp, .psd, .litemod, .das, .srf, .3fr, .p7c, .jpg, .wbd, .xdl, .vcf, .xy3, .svg, .bar, .raf, .wm, .yml, .bkp, .wp5, .p12, .zdc, .cdr, .wbc, .cas, .m3u, .wmv, .xxx, .nrw, .map, .hkdb, .hvpl, .xlsx, .ai, .syncdb, .d3dbsp, .wmv, .docx, .wp7, .kdb, .hkx, .wsh, .ltx, .cr2, .wmo, .tor, .cfr, .rgss3a, .jpeg, .mov, .mdf, .zi, .wav, .pptx, .rwl, .xlsb, .xll, .wpd, .3ds, .webdoc, .docm, .xx, .slm, .wcf, .hplg, .sis, .erf, .wpw, .dbf, .ztmp, .wire, .wbmp, .ppt, .xlsm, .sum, .avi, .1st, .zw, .indd, .rb, .db0, .r3d, .pdf, .menu, .sav, .itdb, .wp, .wdp, .pst, .t13, .bc6, .wot, .sidd, .vfs0, .x3f, .py, .p7b, .xlsx, .qic, .pem, .wpe, .js, .zabw, .wbm, .wn, .forge, .wma, .xbdoc, .sie, .1, .0, .dazip, .xlsm, .xlk, .sidn, .fsh, .itl, .xbplate, .wgz, .wri, .dcr, .mrwref, .txt, .wdb, .pkpass, .zdb, .yal, .dmp, .wps, .fpk, .xml, .gdb, .lbf, .vpp_pc, .rar, .wmf, .accdb, .wbz, .3dm, .bay, .mef, .ybk, .pdd, .xar, .fos, .sid, .xyp, .y, .gho, .csv, .srw, .mdbackup, .xld, .wb2, .zip, .flv, .orf, .z3d, .wpd, .wsd, .x3d, .tax, .m2, .esm, .re4, .wotreplay, .vtf, .wma, .m4a, .zip, .vdf, .icxs, .pfx, .css, .jpe, .ws, .bsa, .epk, .mdb, .wpg, .odm, .bkfi
Each file that has been encrypted by the Rryy ransomware will be renamed. It will append the extension ‘.rryy’ at the end of the name of the affected file. Thus, a file named ‘image.jpg’, after it is encrypted, will receive the name ‘image.jpg.rryy’. To encrypt as many files as possible in the minimum time, the virus does not encrypt the entire file, but only its initial part in the amount of 154 kb. The Rryy ransomware encrypts files sequentially, when all files in the directory are encrypted, it places a new file in it. This file is called ‘_readme.txt’ and its contents are shown below.
The ‘_readme.txt’ file is a ransom note that is a message from Rryy creators. In this message, the criminals report that the victim’s files are encrypted and there is only one way to decrypt them – purchase the key and the decryptor from them. Attackers set the price for the key and decryptor at $980. If the victim pays the ransom within 72 hours, then Rryy authors agree to make a discount of half the ransom, that is, reduce the size of the ransom to $490. Criminals offer to decrypt one file for free. To do this, the victim needs to send this file to one of the email addresses listed in the ransom demand message. But successful decryption of one file does not guarantee the possibility of decryption of files even after payment of the ransom.
Text presented in the Rryy ransomnote:

In the ransom note, the Rryy authors report that it is impossible to decrypt files without a key and a decryptor. In general, this is true; to decrypt .rryy files, you must use the key and the decryptor. This is confirmed by the security researchers. As we reported at the very beginning of this article, there is a free Rryy File Decrypt Tool, which in some cases can decrypt .rryy files. In the case when it could not decrypt the files, there are several more methods, each of which can help the victim restore the files encrypted by Rryy ransomware. These methods do not require the use of a key and decryptor, and therefore are suitable for all victims.
How to remove Rryy ransomware virus
You need to remove the Rryy ransomware virus and its autostart entries before proceeding to decrypt or restore encrypted files. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection. Read the entire manual carefully. To make it easier for you to follow the instructions, we recommend that you print it or open it on your smartphone.
It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Rryy ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Rryy virus, then let us know in the comments, we will try to help you.
To remove Rryy ransomware, follow the steps below:
Kill Rryy virus
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Rryy ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Rryy ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Rryy ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable Rryy Start-Up
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.
Close Task Manager.

How to decrypt .rryy files
To decrypt .rryy files, you need to use a unique key and decryptor. Security researchers confirm that it is impossible to access the contents of encrypted files without decryption. Renaming the affected files, changing their extension cannot help the victim, the files will still remain encrypted. Fortunately, Emsisoft created a free decryptor, which in some cases can decrypt .rryy files.
To decrypt .rryy files, use Rryy File Decrypt Tool
- Download Rryy File Decrypt Tool from the following link.
STOP Djvu decryptor
- Scroll down to ‘New Djvu ransomware’ section.
- Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
- Run decrypt_STOPDjvu.exe, read the license terms and instructions.
- On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
- Click the ‘Decrypt’ button.
Rryy File Decrypt Tool is a free decryptor that can decrypt files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the ‘online key’ is in the hands of criminals and this key can not be determined. But even in this case, there is a chance to restore the contents of encrypted files, we will talk about this in section “How to restore .rryy files” of this article.
How to find out which key was used to encrypt files
Since Rryy File Decrypt Tool only decrypts files encrypted with the offline key, each Rryy’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.
Find out the type of key using ‘_readme.txt’ file
- Open the ransom demand message (‘_readme.txt’ file).
- Scroll down to the end of the file.
- There you will see a line with the text ‘Your personal ID’.
- Below is a line of characters that starts with ‘0493’ – this is your personal id.
Find out the type of key using ‘PersonalID.txt’ file
- Open disk C.
- Open directory ‘SystemID’.
- Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the Rryy ransomware used to encrypt files.
The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Rryy virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.
Rryy File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .rryy files, Rryy File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Rryy authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.
Rryy File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .rryy files, Rryy File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .rryy files.
This video step-by-step guide will demonstrate How to remove Rryy virus, Decrypt/Recover .rryy files.
How to restore .rryy files
If the Rryy File Decrypt Tool did not help you, or your files are encrypted using an online key, then there is no need to panic! There are several other alternative methods that may help you to restore the contents of encrypted files. Once again, remember to be sure to check your computer for ransomware and malware using free malware removal tools. You must be sure that Rryy ransomware is completely removed.
