Unlock92 .zip – Distribution

In order to be spread onto the computers of victims, the Unlock92 ransomware may come either via e-mail messages that contain malicious attachments or via other types of files, uploaded on suspicious websites.

If spread via e-mail, te .zip variant of Unlock92 ransomware may be replicated with the aid of malicious attachments, whose primary purpose may be to get users to download and run the attachment while it pretends to be a document of importance, like an invoice, receipt or even legal document.

If the file is uploaded online for download, it is usually an executable type of file whose primary purpose is to convince users that this is a legitimate type of executable available for free download. Such files are often sought after programs, like installers, portable software, cracks, patches and other license activators of different types.

.zip Files Virus – Activity

Dubbed Unlock92 Zipper, this ransomware virus aims to archive the files on your computer and put them in a password-protected .zip file, preventing you from opening the files. The virus does this by dropping it’s malicious payload after you have triggered it’s infection file.

After the payload is dropped, it may reside in the following Windows directories:

  • %AppData%
  • %Temp%
  • %Local%
  • %LocalLow%
  • %Roaming%

After the files of the affected computer have been dropped on the victim’s computer, the ransomware may also display it’s ransom note with random name, which has the following contents:

Если хотите вернуть ваши файлы отправьте один небольшой архив и файл KEY.VL на e-mail: un92@protonmail.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: {Tor web page}
– там будет указан действующий почтовый ящик.
Пароль для архива состоит более чем из 50 символов. На самостоятельный подбор уйдёт не один год.

Judging by the ransom note, it appears as if the cyber-criminals want victims to visit a tor-based wep page where they can make the ransom payment.
