What is .cxk_nmsl files virus .cxk_nmsl files virus is also known as .cxk_nmsl ransomware and encrypts users’ files while asking for a ransom.
.Cxk_nmsl files virus also known as CXK-NMSL ransomware is a ransomware from an unknown hacking collective aiming to infect as many users as possible. Due to the fact that there is currently no information available about the distribution methods we anticipate that the most popular ones are to be used. The virus may start different malicious components and in the end will encrypt target user data with a strong cipher, resulting in them being inaccessible and renamed with the .cxk_nmsl extension. The victims will be blackmailed into paying the hackers a “decryption fee”.

cxk_nmsl Files Virus — Version 3.3 Released in February 2020
Security researchers have discovered a new version of the cxk_nmsl Files Virus ransomware which is titled as version 3.3 — so far this is the latest iteration. It includes a new ransom note which gives us reasons to believe that it may be possible that a different group is behind the attacks.
The virus analysis shows the threat contains a lot of advanced functionality, the active components are the following:
- Data Modification — The main virus engine can rename, delete and modify existing files which are found on the victim’s hard drive.
- Security Bypass — The virus engine has been found search for any installed security applications and actively bypass them. This can work against most of the popular types of software — firewalls, anti-virus programs, sandbox environments and virtual machine hosts.
- Network Activity — The cxk_nmsl virus can check if there is an active network Internet connection. We anticipate that in future releases the developers can integrate a Trojan module which will allow the hackers to take over control of the victim machines.
- Additional Malware Delivery — Other viruses can be installed by an active cxk_nmsl virus infection: Trojans, ransomware, hijackers and cryptocurrency miners.
A dangerous feature of this ransomware is that it includes valid signed security certificates which makes discovery very dangerous.
cxk_nmsl Files Virus — Update September 2019
The cxk_nmsl Files Virus is a generic malware which is known to researchers under several names including Chinese BAT or Trojan Bat Ransom. It is being spread by an unknown hacking group, presumably from China or a Chinese-speaking country. What’s particularly dangerous abut it is that the behavior will change depending on the actual local conditions or the instructions of the hackers. This malware sequence is run by creating a special BAT file that will include the commands that are to be run.
.cxk_nmsl Files Virus – Detailed Description
As a new ransomware the .cxk_nmsl Files Virus will use the traditional tactics of spreading to the intended users. A large part of the viruses that are sent by criminals make use of email phishing campaigns and can create malicious sites that appear as being operated by a well-known service and company. They are usually hosted on domain names that sound familiar and the pages may even include security certificates.
The other common way of spreading the .cxk_nmsl files virus is by crafting special file carriers that will institute the threat as soon as the users open them up. This includes any macro-infected documents which have malicious commands built into them, this can include all popular formats: presentations, text documents, spreadsheets and databases. The other type is the creation of malicious application installers which are often of software that is frequently downloaded by end users. These programs can also be spread over file-sharing networks, specifically BitTorrent where both pirate and legitimate content is found.
As soon as the infection is made the .cxk_nmsl Files Virus will start to launch its built-in modules. By following the example of most modern virus threats this will begin the infection with a boot options change which will automatically start the main engine as soon as the computer is powered on. This is done in order to make sure that the virus will always start and be able to meddle with the system. A very important component which is run by the main .cxk_nsml files virus engine is the data harvesting one which is designed to collected information that can be used to identify the victims and be used for crimes like identity theft. If any machine information is gathered then it can be used to create unique signature which will be assigned to each compromised machine.
The collected information about the infected systems can be used to scan the system for any security software that can block the proper execution of the threat. The list includes any anti-virus programs, firewalls, sandbox environments and virtual machine hosts. They will be bypassed or entirely removed.
What’s more dangerous is the fact that the virus may lead to various Windows Registry changes — this will result in serious performance issues, data loss and unexpected errors.
The ransomware engine will be started following the completion of the modules. By using a built-in list of target file type extensions: archives, databases, multimedia files, documents, backups and etc. All affected files will receive the .cxk_nsml extension and an associated ransomware note will be made in order to blackmail the victims into paying the operators a decryption fee.
.cxk_nmsl Files Virus – What Does It Do?
The .cxk_nmsl 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 .cxk_nmsl 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
