  1. Note: It is recommended to make a backup of all important files before using the decrypter. Link to decrypter download page. <- The decrypter will tell you if your files are decryptable, whether you're dealing with an "old" or "new" variant of STOP/Djvu, and whether your ID is online or offline. Link to instructions for using the decrypter (PDF). Link to "file pair" submission form. Link to more information about the decrypter. <- Article at BleepingComputer.com Link to more detailed information about STOP ransomware (covers more than just STOP/Djvu). <- Forum post at BleepingComputer.com Can I report this encryption of my files as a crime? Yes. Distribution of malicious files and holding property for ransom are criminal acts in many countries, and we encourage all victims to report such incidents to the national law enforcement in the country where they reside as this helps them determine how best to prioritize investigations into such criminal activity. There is a list of national law enforcement agencies who are participating in the No More Ransom project at the following link with information on how to file a report (if you live in a country not on the list then feel free to report the incident to your local law enforcement): https://www.nomoreransom.org/en/report-a-crime.html Someone says they can decrypt my files, but I will have to pay them. Is this safe? Such individuals or companies are either scam artists, or they are paying the ransom without telling you and overcharging you for it. Either way we recommend avoiding any contact with those who claim they can decrypt your files for a fee. How do I remove the ransomware? The STOP/Djvu decrypter will stop the ransomware from running so that it can't continue encrypting your files, however it doesn't completely remove the ransomware. Most Anti-Virus software will detect STOP/Djvu if you run a scan for it, however if you don't have Anti-Virus software installed then you can run a Malware Scan with Emsisoft Emergency Kit (free for home/non-commercial use). Note that formatting the hard drive and reinstalling Windows will also remove the infection, however this ransomware is particularly easy to remove, so if a computer is only infected with STOP/Djvu then formatting the drive would be unnecessary. Will removing the infection unlock my files? No. Your files are encrypted. This encryption needs to be reversed (via a process called "decryption") before your files will be usable again. This encryption cannot be removed or undone simply by removing the STOP/Djvu ransomware infection. The decrypter can't decrypt my files? In most cases this means you have an online ID. It could also mean your files were encrypted by a newer variant of STOP/Djvu. See below for explanations. Why won't the decrypter run? The decrypter requires version 4.5.2 or newer of the Microsoft .NET Framework, so this could mean your version of the .NET Framework is out of date. We recommend installing the latest version of the .NET Framework (4.8 at the time of writing this), and then trying the decrypter again. What does "Remote name could not be resolved" mean? This can happen if your computer isn't connected to the Internet. If your Internet connection is working, then it can also be an indication of a DNS issue, and we recommend you reset your HOSTS file back to default if everything else seems fine. Microsoft has an article about this at the following link: https://support.microsoft.com/en-us/help/972034/how-to-reset-the-hosts-file-back-to-the-default Why is the decrypter stuck on "Starting"? When you run the decrypter, it looks for encrypted files. It will say "Starting" until it is able to find some. If the decrypter remains stuck on "Starting" for a long period of time, then this means it is unable to find any encrypted files. Offline ID. When the ransomware can't connect to its command and control servers while encrypting your files, it uses a built-in encryption key and a built-in ID. Offline ID's generally end in t1 and are usually easy to identify. Since the offline key and ID only change with each variant/extension, everyone who has had their files encrypted by the same variant will have the same ID and the files will be decryptable by the same key (or "private key" in the case of RSA keys). Online ID. In most cases the ransomware is able to connect to its command and control servers when it encrypts files, and when this happens the servers respond by generating random keys for each infected computer. Since each computer has its own key, you can't use a key from another computer to decrypt your files. The decrypter is capable of working around this with older variants as long as it has some help, however for newer variants there is nothing that can be done to recover files. Old Variants. Old variants were those in distribution until near the end of August, 2019. Our decrypter supports offline ID's for almost all older variants, and can decrypt files for those with offline ID's without needing any help. For online ID's, it's necessary to supply file pairs to our online submission form so that the decrypter can be "trained" how to decrypt your files. A list of extensions from older variants can be found at the bottom of this post. Is it possible to change an online ID into an offline ID? Your files' ID serves to identify which private key is needed to decrypt your files. If you were to somehow change the ID that was added to your encrypted files, then all you would accomplish is making it impossible to decrypt your files at all, even if you paid the ransom. It is imperative that you don't attempt to modify your encrypted files if you want to make sure that they can be decrypted some day. New Variants. These use more secure RSA keys which are impervious to most types of attacks. Support for some offline ID's has been added to the decrypter for newer variants, and support for new offline ID's will be added as we are able to figure out private keys (decryption keys) for them. As for online ID's, due to the usage of RSA keys, there's currently nothing the decrypter can do to help recover files. How long does it take to add support for new offline ID's to the decrypter? Private keys for offline ID's are donated by victims who paid the ransom, and there is no way for us to be able to estimate when this will happen. If you have an offline ID then try running the decrypter once every week or two, and if we have been able to add the private key for your ID then it will start decrypting files. Will it ever be possible to decrypt new variants with online ID's? That depends on whether or not law enforcement is able to catch the criminals who are behind this ransomware. If law enforcement is able to catch them and release their database of keys, then we can add those to our database for decryption. Are there any ways to recover/repair files that can't be decrypted? In most cases this is not possible, however there is a tool called DiskTuna that can help repair some videos that have been encrypted. This tool was made by a third-party, and they are not affiliated with us, however one of our developers has verified that it does work in at least some cases. You can find more information at this link. What is a file pair? This refers to a pair of files that are identical (as in they are the exact same file), except one copy is encrypted and the other is not. Our decryption service can analyze the differences between an encrypted file and an original unencrypted copy of the same file, allowing it to determine how to decrypt that type of file. For most victims with an older variant of STOP/Djvu, submitting file pairs will be the only way they will get their files back. File pairs only work for one type of file. Due to the way encryption works in STOP/Djvu, file pairs can only help the decryption service figure out how to decrypt one type of file. For instance, if you submit a file pair for an MP3 file, then the decrypter will be able to decrypt all of your other MP3 files, however it won't be able to decrypt any other type of file. There are some exceptions to this, such as certain newer Microsoft Office documents (such as DOCX and XLSX) since those files are technically ZIP archives. The decrypter can't decrypt all of my pictures even though I submitted file pairs for them? JPEG/JPG images have a format oddity that causes file pairs to be specific to each source of pictures, rather than the file format in general. As an example, if you have pictures from two different cameras, and submit a file pair from the group of pictures from one of the cameras, then the decrypter will only be able to decrypt files from the camera that the file pair came from. In order to decrypt all JPEG/JPG images, you will need to submit file pairs from every source you've obtained those pictures from. Extensions from older variants that the decrypter supports:

  2. You've not yet adequately answered my questions. I have however noticed that EAM hasn't nagged me recently; does that mean that someone's tweaked the code to stop the nagging, or is it just coincidence (since the nags seemed to be at irregular intervals)? If the nagging is going to continue, then please explain once and for all WHY this authentication is needed for a user who is not using the website-based console. Please also address all the other points I've raised here, namely: - the possibility (if there's not multiple instances) that your backend server is a single point of failure - the possibility (if someone manages to hack into those server(s)) of the security of customers' systems being at risk. I'm sure you won't have forgotten that an Emsisoft server was breached in Jan-Feb 2021. I know that was reported as a fairly minor data leak, but that doesn't mean that other kinds of breach are impossible. I wonder how much thought Emsisoft have given to how they'd mitigate effects (on customers' systems) if such a breach were to occur. And, do you run disaster-recovery tests on your infrastructure? If eg a data-centre which houses your servers burns down (as did OVHcloud, Strasbourg, France, in March 2021) how long will your customers be affected for? - the point about the website console, if one chooses to change to "Local Only" resetting my (private) PC's EAM configuration to default - two problems there: why would it reset anything, and secondly how/why (if my PC is not authenticated to the workspace) does it have the right to perform a reset? - the tooltip text for the "Local Only" option I do not think I have muddied the waters with conjecture. But note that "conjecture" means speculation based on inadequate information. The very fact that I've been asking the initial question here (about the nagging) over and over again without a proper answer being given has not helped. Questions about single points of failure etc might have been less relevant before when your customers' systems were less tightly integrated with your servers; I mean all of us could cope with occasional absences of signature updates. But centralised control of our copies of EAM by your servers considerably heightens risk for customers. I would like you to understand that I ask about these things based on my professional experiences in a UK bank's datacentre.

  4. It's more difficult with pictures. They are more compressed and less fragmented than video files, so the cipher damages them much. If you transferred a collection of photos from one disk to another and after that did not fill this place on the disk with anything, then using data recovery programs you can recover some of the photos from the previous location.

  6. Because the decrypter already supports it. The reason it can't decrypt files encrypted by this newer variant is due to the fact that we don't have the private key for it's offline ID. We have to wait for a victim with an offline ID who paid the ransom to donate their private key to us.

  7. Hello, The posts you found are more than 5 years old. In terms of security software that means the information there is severely outdated. In the past years considerable changes have been made to our products and currently Emsisoft Anti-Malware protects against fileless malware. Fileless malware detection has nothing to do with the reputation settings you asked about; our behavior blocker routines were adapted to adequately detect and block fileless malware a few years ago.

  11. Hello @KYO, Welcome to the Emsisoft Support Forums. That extension is used by STOP(DJVU). Unfortunately, we no longer have any method to decrypt STOP(DJVU) unless the encryption occurred before the 29th of August 2019. Please refer to this blog post for information about a decrypter that may work, and also for support instructions if it does not: https://blog.emsisoft.com/en/34375/emsisoft-releases-new-decryptor-for-stop-djvu-ransomware/ I understand it is frustrating, but currently, we cannot decrypt files that we do not have the Private Encryption Key in our Database. There's the possibility that law enforcement may be able to catch the criminals and release their database of private keys, meaning that you could try again using the tool in few weeks in case something changed. We do not recommend paying the ransom unless there is absolutely no other choice. 22% of those who paid a ransom never got access to their data. 9% said they got hit with additional ransom demands after paying. We’re talking about criminals, after all. Our recommendation is to save a backup of your encrypted files and keep it in a safe place in case decryption is possible at some point in the future. Please review our Protection Guides at your leisure, they contain several tips on protecting your computer and data. We also recommend keeping an eye on BleepingComputer's newsfeed, as they will usually report on new developments with ransomware decrypters: https://www.bleepingcomputer.com/ If you have an RSS feed reader, then they also have an RSS feed so that you don't have to manually check for news: https://www.bleepingcomputer.com/feed/ Please consider subscribing to a reliable anti-malware application to avoid similar issues in the future. You can get our full version of Emsisoft Anti-Malware here: https://www.emsisoft.com/en/pricing/ I know it’s a big loss for you. We are glad to offer this service for free and help as much as we can, but there is not always an immediate resolution for all the cases.

I understand it is frustrating, but currently, we are not aware of any ways to decrypt files with Online-ID and some recent forms of STOP(DJVU). Please read this Topic. It contains information about your situation and whether or not your files can be decrypted. https://support.emsisoft.com/topic/32045-about-the-stopdjvu-decrypter/

  17. Yes, it is probably true. The Emsisoft Decryptor defines this fact very accurately. What to do? Everything is lost? No. It is recommended that you save the encrypted files to an external drive. It is possible that in the future the decryption method will change or the extortionists will publish the decryption keys. There have been several such unexpected cases recently when others extortionists shut down their ransomware projects and published decryption keys and master keys for everyone who got encrypted. The percentage of such happy cases is small, but it still exists. Next, I'll tell you what you need to do now, immediately, and what you can try after that.

  19. Adding the decryption key to the Emsisoft Decryptor depends on the voluntary transfer of the key by someone who paid the ransom. When this will be done, no one can predict. Therefore, the wait may drag on indefinitely. --- Only after neutralizing all malicious files ... I recommend this following method only when there is no other way. You decide what action to take. This is not the decryption, it is the recovery of certain types of files using the features of these files. 1) If you have encrypted archives, you can partially recover them. Only 1-2 files are damaged there. Remove the extension that the ransomware added to the archives, and extract the files in the usual way. Everything except 1-2 files will be fixed. If there is only 1 file in the archive, then it will most likely be unrecoverable. 2) There is an alternative (additional) way to recover some media files: WAV, MP3, MP4, M4V, MOV, 3GP. https://www.disktuna.com/media_repair-file-repair-for-stop-djvu-mp3-mp4-3gp But before trying the alternative variant with media files, it is recommended that you make a copy of the encrypted files. Something will be restored better, something will be restored worse. An alternative method for other files has not yet been found.

  22. Good, you have an offline ID. This is how the decryptor informs that it does cannot decrypt the files now because it does not yet have the decryption key for this variant. Its addition to Decryptor depends on the voluntary transfer of the key so that others victims can decrypt the files without paying a ransom. But we cannot predict when someone will share the purchased key with the 'Emsisoft Decryptor' developers. The encrypted files need to be saved to an external drive to prevent encryption from being repeated by another ransomware attack. Highly undesirable try different software that is not designed to decrypt files after the 'STOP Ransomware'. Other software can damage your files and make decryption impossible. If you are doing experiments, make a copy of the encrypted files for testing.

  28. I assume that when you run one of the .exe files shown in your first screenshot it unpacks another .exe, then runs that. The problem is that the second .exe - in a subfolder of \temp\ is the one that gets the BB detection. I expect that the subfolder has a different random name every time something is unpacked. There's probably not a satisfactory solution, since although you could set up an exception for files in \temp\, that's a really bad idea because malware is also quite likely to get unpacked and run there and if that happens you definitely want to know about it. Sometimes .exe's that contain packed files can be inspected or unpacked using a tool like 7z; if that's possible with these files you could at least unpack them into a specific folder whose name you determine, and have an exclusion for that folder.

  31. This ransomware hasn't changed much since it was first analyzed over 2 years ago. The only major change was when they switched to using RSA keys, which is what makes the ransomware non-decryptable. Right now there's no way to decrypt files that have been encrypted by the STOP/Djvu ransomware without having the private key for the ID embedded in the encrypted files.

  34. No. Your files aren't infected, they're encrypted. Just make sure the ransomware itself have been removed from your computer first, because it will continue to encrypt files if it's still running. Emsisoft Emergency Kit can detect and remove it. https://www.emsisoft.com/en/home/emergencykit/ You can save them wherever you want. My only recommendation is to keep them saved on a device that you don't keep connected to your computer, and it's not a bad idea to have two or more backup copies just in case anything happens to one of them. Probably not. Most ransomware will try to make sure that it is impossible to recover files, even from Volume Shadow Copies. Recovery points are stored in a protect folder, and most tools don't have access to them. There may be tools out there that can access them and save copies of them like Shadow Explorer does, however I'm not familiar with those tools.

  37. I don't think STOP/Djvu will usually double-encrypt files, however it's still technically possible because the ransomware is known to be buggy and sometimes it just does weird and unexplainable things. It's best to get it off of the system and then avoid any pirated software, movies, music, etc. after that to help prevent it from happening again.

  40. Hello @GRZESIUUUUUUU Dzień dobry ! The 'STOP Ransomware' variant with .weui extension adds has appeared recently. Decryption is only possible after the decryption key is obtained from someone who bought it. Recently, this has happened very rarely. Therefore, the chance of getting the decryption key is very small. We do not give up hope that this will be done. It is recommended to keep the encrypted files and the ransom note file in the hope that the decryption key will be obtained in the future. Powodzenia!

  42. You'd just make things worse. You can't remove the encryption without the private key, so all you'd do is double-encrypt the files, and risk corruption the original encryption that was applied by STOP/Djvu (thus potentially making files unrecoverable).

  47. Have you tried our decrypter yet? https://support.emsisoft.com/topic/32045-about-the-stopdjvu-decrypter/ Does it say your files have an online ID or offline ID? For files with offline ID's it will probably start decrypting them without requiring you to do anything else, assuming we have the private key for that variant's offline ID. For files with an online ID, you'll have to supply file pairs to our online submission form. There's more information at the link above.

  48. I recommend excluding the decrypter in your Anti-Virus software to minimize any interference with it.

  49. Hi @Kevin Zoll, Thanks for your comprehensive answer. Also I just read that informative post written by @GT500 I'm sure you'll find how to fix this issue someday As far as I can see for now, unfortunately, I think I should clean my driver from [useless] exe.topi files and go on... Thank you again.

  50. Hello @SalasKafa, Thank you for contacting Emsisoft Support. TOPI is a newer variant of the STOP/DJVU family of ransomware and is not supported by our decryption tool. Any ID ending in t1 is an Offline ID anything else is an Online ID. This is important as it tells us how the encryption key was generated. There may be multiple Ids, especially if communication between the target system and the command & control server is interrupted for any reason, or because the file encryption was done in stages to avoid detection. An Offline ID means that the encryption key pair was generated locally and the encryption key is encoded in a file. An Online ID means the encryption key pair was generated and stored on a remote command & control server under the control of the ransomware gang responsible for encrypting your files. Why is this important? The ID of the file(s) is how private encryption keys are identified. If we have a private encryption key matching the ID for a file(s) then that can be used to decrypt the file(s). However, this is all contingent on us having a matching private encryption key in our database. The downside of all this is that we are not currently in possession of private encryption keys for the TOPI variant of STOP/DJVU.
