Distribution of Nozelesn Virus
Nozelesn virus is a new data locker ransomware that has been released in attack campaigns against computer users worldwide. The threat could be utilizing widely used tactics of distribution to infect computer systems.
One of the easiest ways for the criminals to spread the payload of Nozelesn ransomware is by attaching it to email messages that are later released in active attack campaigns. The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files which users open without hesitation. Once opened on a target host these compromised files trigger the ransomware payload and infect the device with Nozelesn crypto virus. Other infection tactic related to emails is hyperlink inserted in the content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest.
Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including Nozelesn virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.
The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind Nozelesn virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious add-ons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.
Impact of Nozelesn Ransomware Virus
The Nozelesn virus is newly discovered threat that appears to be made by the criminals behind it. It appears to contain no code sources from other ransomware strains which shows that this is probably a custom threat targeting specific computer networks.
It follows a sophisticated behavior pattern that first scans the host system for any anti-virus programs, sandbox environments or virtual machine hosts that can interfere with it’s correct execution. This means that the engine can be customized to harvest sensitive information as well — data that can expose the victim’s identity. Examples are their name, address, phone number, location and passwords.
The next step in the infection process is the manipulation of the Windows Registry so that the Nozelesn virus is automatically started once the users boot in their computers. This module can also be programmed to disable the boot recovery options which makes it very difficult to remove the threat using the manual methods.
If other system manipulations are specified in the sequence then the virus can also modify the entries belonging to user-installed applications and the operating system itself. This can result in the inability to start certain functions or services, as well as an overall drop in performance.
If the Nozelesn virus is programmed to include a Trojan instance then it will contact a hacker-controlled server from where the operators will be able to spy on the victims in real time. Other possible actions include the ability to take over control of the machines and deploy additional threats to the hosts.
An additional measure taken by the hackers is the removal of all Shadow Volume Copies and System Restore Data from the infected machines. This makes file restore possible only with a professional-grade solution, refer to our instructions for more information.
Once all modules have been executed the ransomware engine will be started. Using a strong cipher it will target files based on a built-in list. An example list includes the following data:
- Images
- Videos
- Music
- Documents
- Archives
- Backups
All victim files are renamed with the .nozelesn extension and the ransomware note is created in a HOW_FIX_NOZELESN_FILES.htm that reads the following message:
