    Hallo Oli, Ich benutze Google Translate und meine Muttersprache ist Englisch. Möglicherweise wurde der vorläufige Termin für das Ende des Windows 7-Supports für 2021 verpasst. Wir werden es dann neu bewerten und wenn es möglich ist, die Unterstützung für Windows 7 zu erweitern, werden wir es tun. Andere Antiviren-Unternehmen verwenden ein Datum von 2022, enthalten jedoch Formulierungen, mit denen sie den Support vorzeitig beenden können. Wir haben diesen Wortlaut nicht aufgenommen und sie zu gleichwertigen Aussagen gemacht. Stapp, Claude, bitte kläre, ob mein Wortlaut verwirrend ist. Google.

    This is a newer variant of STOP/Djvu, and your ID is an online ID, so there is currently no way to decrypt your files. There is more information at the following link: https://support.emsisoft.com/topic/32045-about-the-stopdjvu-decrypter/

    Hello @Mike77, 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. Despite that, I would like for you to run the STOP/DJVU decryption tool anyway. That will accomplish a couple of things. First, it will deactivate and remove any malware that was installed by the ransomware. This will prevent new files from being encrypted and will prevent re-encryption if files are restored from a backup. Second, the decryption tool will determine the ID of the encrypted files. 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. NOTES: If the decryption tool tells you the files cannot be decrypted, then they cannot be decrypted. That is not an error message. If your file(s) have an Online ID that means that the file(s) encryption keys were generated and stored on a command & control server under the control of the ransomware gang responsible for encrypting your files. We do not have access to those keys. If your files(s) have an Offline ID and were not decrypted it is because we do not have the corresponding decryption key in our database. Do not ask us when we plan on adding it, because we do not have it or a way for generating your decryption key. Our database does include some Offline ID decryption keys for newer variants of the STOP/DJVU family of ransomware. If the files were encrypted with an Offline ID that matches the ones in our database, then our decryption tool will be able to decrypt those files.

    The taskmanager IO write bytes, does not necessarily mean HD writes. network writes etc are logged too. You can check real HD writes in the Windows resource monitor, a2service selected, Disk tab, see example below. This shows disk IO during an update. simple check to proof this is: Disable EAM selfprotection and kill process a2start and a2guard, you will notice that the IOwrites counters nearly stops. The continuous IO writes mainly is internal EAM network communication and no disk writes.

    Thanks for updating rustyDusty, and for helping, JeremyNicoll.For anyone else reviewing this, the exclusion is made like this: Open Emsisoft Anti-Malware, click "Settings" then the "Exclusions" tab. Click 'add folder' in the exclude from monitoring section, navigate to the target folder "C:\Program Files\MPC-HC\" (or other location if you did not install it there), and click OK. Note: Exclusions only apply to programs started after the exclusion is made. To be effective, you may need to restart the process or program, or restart the computer, depending on the program being excluded. In this case, a reboot is recommended.

    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? It's an indication of a DNS issue. Our first recommendation is to reset your HOSTS file back to default. 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 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 in the YouTube video at this link (there's a download link in the video's description). 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:
