  1. When you pay, the criminal gives you a decryptor and your personal key. So yes, they don't require internet access because they give you a key you have to input into the program. We call them "online" and "offline" keys based on how they are used with the malware. The FAQ clearly states this, but I will re-summarize it for you... Online Key: The malware talked to their server at the time you were infected, and their server generated a key unique to you. Only the criminals have your key. Offline Key: The malware failed to talk to their server, and resorted to an "offline" key that is embedded in the binary. Everyone who has a file encrypted and has the corresponding ID (also embedded in the malware) will have the same key for those files. The NEW variants (aka yours) all use RSA encryption, so these keys are not breakable. Due to different circumstances, many times some files are encrypted with the Online key, and others with the Offline key; the malware constantly reaches out to it's command server, so if even one of those times fails, then that "run" of the malware encrypts with the Offline key. We sometimes are able to acquire the Offline keys after one victim has paid, and it can help others recover some files, but the Online keys remain unique and do not help anyone else. Our decryptor requires internet access because we store all the keys and keystreams we acquire on our server. This allows us to manage it without having to push a decryptor update every time we get a new key, and for ease of the user in not having to input anything additional to the program. Please READ THE FAQ, this is all explained in there. Only the criminals have the Online keys; they are impossible to break. If you really want to "name a price" and throw money at the problem, feel free to invest in the quantum computing industry; we're still decades away from even attempting to use quantum computers for breaking RSA-2048.
  2. If you have a valid file pair that is too large for the submission portal to accept, you will need to upload them to a third-party sharing site and provide them to us to add to the server manually.
  3. This company deceives its customers and pretends they have a magic method of decrypting everything, when they are clearly just paying the ransom. IT is one of many who do this with absolutely no transparency to the customer. And a bit of a more NSFW tirade I went on recently about them:
  4. The groups behind Phobos actually compromise your system via RDP or other remote software you had open... no antivirus on the planet can protect you if someone had full control of the server.
  5. With it being New Djvu, your files will only be decryptable for free if they were encrypted by the offline key once we acquire it. If the decryptor reports your files have the ID ZioGB1sCYacbrJajtnJKEUKt6xYM3QPgwAPNAwt1, then they were encrypted by the offline key, and thus possibly decryptable in the future. Otherwise, it is an online key, and there is nothing we will be able to do to help since only the criminals have your online key(s).
  6. We have not acquired any new keys since the release of the decryptor. The criminals stopped using that server by time we got the keys, and have been infecting users from another server.
  7. The ".Snc" variant is not supported by the decrypter, but we are currently working on it. Can't guarantee it will be decryptable at this point, they made some changes as expected.
  8. @broniusr I've fixed that now. Please try re-downloading for v1.0.0.1.
  9. @broniusr The decryptor has been updated, please try downloading it again. If you run it from the same directory as before, it should pickup the key file from the previous session, and you won't have to re-bruteforce it. Thanks for reporting the bug.
  10. You were encrypted more recently than we have keys for, that's why you get that message. Nothing we can do at the present time.
  11. @broniusr You are correct, the malware encrypts up to 0x27100 bytes of the file, and I forgot to test bait files smaller than that limit. I'll post here once the decryptor has been updated to factor for that bug in the malware. Every version of this malware family has had at least one such bug relating to the crypto, so annoying...
  12. Not yet, but decryption of 3.0 is coming soon. The idiot who coded it has an annoying bug that corrupts many files that we have to overcome.
  13. Please upload this file to VirusTotal and provide a link here. C:\Users\dasba\AppData\Local\a8402009-cadb-4977-b8d8-209fe362c63a\2.exe
  14. Yep, as I suspected. The files are corrupted. What's going on is the MP3 format is likely a little bit tolerant of some data loss. GlobeImposter 2.0 does not encrypt the whole file, only like the first few MB I believe. If you were to simply remove the ".DOCM" extension from the file, you would get the exact same result. GetCrypt Ransomware uses a random 4-character uppercase extension, so that's the only reason the decrypter is fooled into "accepting" your file pair. Due to the way I am breaking that ransomware, the tool also cannot actually verify whether the decryption was successful, it just has to blindly throw the crypto at the file.
  15. Mind sharing some of these encrypted MP3s that are supposedly "decrypted"? I have an idea as to what is going on, and it's not actually decryption...
  16. If you can find a file "bginfo.png" on the system in the same folder as the executable, there might be a chance. Otherwise, so far it does not look like it can be decrypted without that file at the current time.
  17. We will really need the executable or commands used to encrypt the files in order to analyze it any more. By the way, the filepair you provided are not the same file before/after the encryption. The encrypted file's filename decodes to "rollup.png". It's just simple base64 encoding on the name.
  18. No, the malware would re-encrypt them...
  19. Do NOT do that. Your files will just get re-encrypted with the offline key, which STOPDecrypter already has. So it's just a complete waste of time and won't accomplish anything but possibly causing more damage to your system.
  20. The .pumax variant is 100% decryptable if you follow the instructions in the README.txt and provide it an encrypted file and its original. Don't bother with the ID and MAC, I don't need to archive those for that variant.
  21. If you can zip up everything they gave you and a few encrypted files and attach it here, we can see what we can do.
  22. Possibly in the future, just give us some time. 😉
  23. To second @GT500, have you heard of a little something called CVE-2019-0708? It's literally an exploit that doesn't require even logging in, completely bypassing MFA... it's not the first such exploit recently, nor will it likely be the last. Good that you have MFA, but seriously put it behind VPN.
  24. It's STOP Djvu Ransomware, please read the FAQ here: In addition, we still need the malware executable for this extension. Please check Task Scheduler for a suspicious task running every 5 minutes, and disable it. Go to Properties, and find the executable it is pointing to, upload it to VirusTotal, and post a link here.
  25. Please follow the instructions in the link ID Ransomware gave you to provide the information needed to archive your case. In addition, we still need the malware executable itself. Check your Task Scheduler for a suspicious task running every 5 minutes or so - go to Properties and find the executable it points to, and upload it to VirusTotal, then provide us the link.
