THREAT REMOVAL

.{Killback@protonmail.com}KBK!Ransom Ransomware virus remove

The .{Killback@protonmail.com}KBK!Ransom ransomware is a dangerous new threat which appears to be made by an unknown criminal collective. A complete code analysis is not yet complete and we cannot report on details about the made infections. So far we have confirmed that it is based on the Globe Imposter 2.0 family. We anticipate that the most popular distribution tactics have been used. One of the most popular ones remains the coordination of email phishing messages which are made to impersonate well-known companies or services. The dangerous code can be placed either in the body contents or any attached files. A similar mechanism is the creation of malware sites that impersonate well-known services and companies. They are hosted on similar sounding domain names and may even include self-signed and stolen certificates.

A common mechanism is the creation of dangerous payload carriers, some of the most popular ones include the following:

  • Application Installers — The hackers can create dangerous setup files of popular end user software: system utilities, office and productivity tools and creativity suites.
  • Malicious Documents — Dangerous scripts can be embedded across all popular formats: presentations, databases, text files and spreadsheets. Whenever they are opened by the victims a prompt will appear asking them to enable the built-in scripts, if this is done the .{Killback@protonmail.com}KBK!Ransom ransomware will be deployed.
  • Browser Hijackers — A popular tactic is the creation of dangerous plugins which are made compatible with the most popular web browsers. They are usually uploaded to the relevant repositories using fake user reviews and developer credentials.

Other delivery methods can be used as well depending on the current attack campaign. They can also govern the specific behavior patterns used by the virus threat. Usually such attacks begin by starting a data harvesting engine which is designed to extract both sensitive information about the victims and their machines. This can be used to conduct crimes like identity theft and financial abuse. In addition the extracted information about the machines can be used to craft an unique ID which is to be assigned to each compromised computer.

When these two modules have finished running various system changes can occur. The most popular one remains the modification of the boot menu options in order to automatically start the threat as soon as the computer is powered on. In many cases this also includes access restrictions upon the boot options thus rendering most manual user removal guides non-working. This can be coupled with removal of sensitive files which will require the use of data recovery tools.

If any Windows Registry changes are planned then data loss and unexpected errors can be presented. In certain situations this can also lead with severe usability problems when accessing third-party applications or operating system services.

As soon as all components have finished running the actual file encryption will start. Like other similar threats a built-in list of target file type extensions will be used, most commonly this includes images, music, videos, archives, databases, executables and etc. The long extension of .{Killback@protonmail.com}KBK!Ransom will be applied to all victim files. An associated ransomware note will be made in a file called decrypt_files.html, as well as a lockscreen and desktop wallpaper.
