Soon after data encryption, malware drops a ransom note in ORID.jpg file which becomes a new computer’s wallpaper. The ransom note is written in the Russian[2] language:

Ваши файлы зашифрованы с использованием криптостойкого алгоритма RSA-2048.
Если хотите их вернуть отправьте один из зашифрованных файлов и файл keyvalue.bin на e-mail: unlock92@india.com
Если вы не получили ответа в течение суток то скачайте с сайта www.torproject.con браузер TOR и с его помощью зайдите на сайт:
http://fnjmegsn7tbrrnkl.onion – там будет указан действующий почтовый ящик. Без браузера TOR зайти на этот сайт невозможно.
Попытки самостоятельного восстановления файлов могут безвозвратно их испортить!

Unlock92 2.0 ransom note

Authors of the Unlock92 2.0 virus ask to send one encrypted file to unlock92@india.com and wait for their response. After that, victims are asked to download a TOR[3] browser and access specific website, where they can learn more about data recovery.

However, we do not recommend contacting them and following their instructions. You will be asked to pay a specific amount of Bitcoins for the data decryption software, but it doesn’t mean that crooks actually have it or are willing to let you use it even if you pay the ransom.

Unfortunately, malware researchers haven’t cracked ransomware’s code and haven’t released a free decryption software. However, victims report that Unlock92 2.0 fails to delete Shadow Volume Copies[4], so they were able to decrypt the majority of their files with ShadowExplorer and similar tools. Hence, there’s a chance to get back your files.

However, before you proceed with data recovery, you need to remove Unlock92 2.0 from the computer. While malware resides on the PC, it can encrypt files again and again after the system reboot. Additionally, if you think about plugging in the external drive with backups, you might get this device affected too.

Unlock92 2.0 removal requires scanning the computer with a reputable anti-malware software like Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus. Before downloading, installing, updating or running security software, you should reboot the device to Safe Mode with Networking as explained at the end of the article.

Malicious spam emails are used to spread ransomware's executable

Developers rely on the popular malware distribution method – malspam. This method allows sending a bunch of emails that inform about various issues, such as, failure to deliver a parcel, necessity to check invoice details, etc. Criminals often pretend to be from popular companies or organizations and copy their credentials. So, fraudulent emails might be hard to recognize.

Additionally, these messages from crooks include a link or button that leads to the infected website or has an attachment. As soon as a victim opens an attached Word, PDF or ZIP archive, malware executable is dropped and immediately activated on the computer.

  • Look up for grammar, spelling or use of English mistakes;
  • Check the attachment with online virus scanners without downloading it;
