Kuus Ransomware – In Depth

Kuus Files Virus uses different methods for spreading its infection. The payload could be present in free download sites and torrent files. If something is promoted as free it could easily contain malicious scripts inside. STOP ransomware could implement such attack behaviors, as people have reported. Hacks, cheats and similar software often has ransomware inside.

The .Kuus ransomware might utilize other means of distribution too, such as spread its infection file as an e-mail attachment. Such emails intend to persuade you to download and run the attachment and they usually depict it as a “urgent” document that is extremely vital. Frequently, the subjects of the e-mail are similar to the examples below:

  • “Your order has been revoked.”
  • “Your ticket.”
  • “Your bank invoice.”
  • “Your PayPal invoice.”
  • “Problem with your visa/mastercard.”

The attachment themselves may either be a .js or various other files in an archive or they might be a .docx or .pdf document with embedded malicious macros. The latter two trigger infection when you allow their web content.

Another mean of distribution utilized by the .Kuus virus is to spread on your computer by being directly posted on a dubious site, where it might appear as If the virus is specifically what you are attempting to download and install, like:

  • Patch for a program.
  • Keygen.
  • Setup Wizard.
  • Self Extractor.
  • Portable program.
  • License activator for Windows or Microsoft Office.

The note has instructions from the virus authors on how to pay and allegedly get your files back upon confirmation. As no guarantee exists, you do not know if after paying the criminals, you will get your files back to normal. Free decryption is usually not available right away, either. Malware researchers warn that you have to have an OFFLINE key (stored on PC) for decryption to take place. If your files are locked with an ONLINE key (stored online), the decrypter cannot work.
