.cs16 Files Virus – Detailed Description

The .cs16 files virus as a new version of the Cryakl ransomware family is being spread to victims worldwide via different distribution techniques. We anticipate that the criminal group behind it is experienced enough in order to create this custom version.

It is being distributed using the most common techniques such as the coordination of email phishing campaigns and the subsequent creation of malware sites. They are intended to convince the users that they have accessed a safe and legitimate site. In order to do so they have included security certificates and host them onto legitimate sounding domain names.

Another tactic is to embed the necessary virus scripts into file carriers of which there are two main types. The first one is the insertion of the necessary code into documents across all popular file types: spreadsheets, presentations, databases and text files. When they are opened by the victims a prompt will appear asking them to enable the built-in code. The other type is the creation of malicious setup packages of popular applications. They are widely downloaded and used by the users. What’s distinct about the file carriers is that they can easily be made part of the phishing emails, sites and can even be spread over file-sharing networks — a popular one is BitTorrent.

As soon as the .cs16 files virus is deployed onto a given computer it will launch its own set of behavior patterns. The first component that is run is the data harvesting module which aims to acquire sensitive information. It can be related to the victims, the harvested information may be used to expose the identity of the victims and use it or crimes like financial abuse. Any machine data which is retrieved may be used to generate an unique ID for each compromised computer.

The retrieved information can then be used by the next component — the security bypass module. It will search the memory and hard disk contents in order to find out if there are any active security programs and services and bypass or remove them.

With this action completed the .cs16 files virus can proceed further by instituting various system modification. A popular step is to modify the configuration of the boot options so that the virus will be started every time the computer is powered on. If Windows Registry changes are made then they will lead to data loss, problems when using the computer and the inability to launch certain applications or operating system functions.

The actual file encryption is done when all prior modules have finished running. Using a strong cipher it will target user data according to a built-in list of file type extensions, including the following:

  • Multimedia Files
  • Backups
  • Archives

All processed files will receive the .cs16 extension and an associated ransomware note will be generated to blackmail the victims into paying the hackers a decryption fee.

.cs16 Files Virus – What Does It Do?

The .cs16 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. It will display the ransomware note to the victims.

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.

The .cs16 Files Virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.
