.Syrk Files Virus – Detailed Description

The .Syrk files virus is a newly discovered web threat which is being spread at the moment in an active attack campaign. There is no information available about the hacking collective behind it and as such we anticipate that they are probably going to use several distribition techniques.

One of the most popular distribution techniques relies on the coordination of email phishing messages that are designed to imitate notifications that have been sent in by well-known companies or services. As soon as the the users interact with the contents the infection will be started. These messages can also server as a model upon which specially-made hacker-controlled sites can be constructed. They are hosted on similar sounding domain names to the original services and may include stolen or hijacked security certificates.

The .Syrk files virus can also be embedded across file carriers that can range across different types of data. There are several popular types which are widely used for ransomware distribution:

  • Malicious Web Browser Plugins — These are specially made extensions made for the most popular web browsers. They are frequently uploaded to the browser repositories with fake user reviews and developer credentials. Usually the descriptions that are posted will promise new features and performance optimizations in order to entice the visitors into installing them.
  • Macro-Infected Documents — They can range across all popular file formats: text files, spreadsheets, databases and presentations. When opened by the users a prompt will appear asking them to enable the built-in scripts. The quoted reason is that this is required in order to correctly view the document.
  • Bundle Installers — The hackers can take the legitimate setup files of popular software and modify them with the necessary .Syrk files virus instructions. To a great extent this can be used with creativity suites, system utilities and even computer games. What’s particularly dangerous about them is that in many cases the users will not know that they have installed a virus onto their computers.

All data files can also be shared across file-sharing networks which are used by end users in order to spread both pirate and legitimate data.

When the .Syrk files virus has completed the intrusion it will start the built-in malicious actions which are governed according to local conditions or specific hacker instructions.

One of the most common actions which are run in the beginning of the attacks is the boot options modifications. This will result in the installation of the threat in a way which will make it a requirement to start the virus as soon as the computer is powered on. In certain cases this can also disable access to the recovery boot options which will make most of the manual user removal guides non-working.

The next step which is commonly done is to scan the system for any installed security software which will be bypassed or entirely removed. Ransomware samples like the .Syrk files virus usually will target the following applications: anti-virus engines, firewalls, virtual machine hosts, sandbox and debug environments.

To make it even more dangerous the virus can search for sensitive data which will be deleted which will recovery much more difficult. Examples include the following:

  • Shadow Volume Copies
  • Backups
  • Restore Points

Advanced virus samples can also proceed with dangerous Windows Registry Changes which can exhibit in multiple issues: data loss, unexpected errors and severe performance and stability problems.

Our analysis reveals that the following Windows Registry values will be affected:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\DisableAntiSpyware
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\\UNCAsIntranet
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\\AutoDetect
HKEY_CURRENT_USER\Control Panel\Desktop\WallpaperStyle
HKEY_CURRENT_USER\Control Panel\Desktop\TileWallpaper
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Hidden
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt

In the end when all modules have completed running the .Syrk files virus will proceed with the actual files encryption. This is done by following the typical behavior pattern of similar threats: target user data will be processed by a strong cipher. Usually this includes the following: backups, databases, multimedia files, documents, archives and etc.

All of the processed files will receive the associated .Syrk extension. In order to manipulate the victims into paying the hackers a decryption fee they will create a ransomware note or a lockscreen instance. The first type is a text document which will blackmail the victims, the second type is a computer program which will block the normal running of the system until it is completely removed.

.Syrk Files Virus – What Does It Do?

The .Syrk Files Virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers.

You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.

→vssadmin.exe delete shadows /all /Quiet
