.cvc File Virus (Dharma Ransomware) – What Is It and How Did I Get It?
The .cvc virus is a new Dharma ransomware release which has been captured in an ongoing attack campaign. This campaign is orchestrated by an unknown hacking group and directed at users worldwide. The detected samples are very low at this moment, for this reason, we assume that these viruses are still a testing release. They are made by modifying the base source code of the Dharma virus and adding in the necessary variables and configuration options. At this moment we assume that the attacks are targeted to users around the world.
Like the previous versions of Dharma, it is possible that the same infection strategies will be used here as well. This involves the creation and operation of virus-infected files — they will appear as safe and legitimate data that is downloaded from a presumably trusted location. The criminals typically create them in documents, files that are commonly used by such programs: presentations, spreadsheets, text documents, and databases. Upon opening them a prompt will be shown asking for the execution of the built-in scripts. The same can be done with application installers — program setup bundles that are of popular programs. They are created by taking the original setup bundles of system utilities, creativity suites, and even computer games.
Different distribution techniques can be used to spread these virus samples. Usually this includes the creation and spreading of email messages. They are created using common templates and will include the virus data either attached or linked in them. The hackers will impersonate letters, notifications, and other types of documents that are received by using this medium. A similar strategy is used with hacker-created sites: they can be download portals, sites, landing pages, search engines, and etc. Such content can be hosted on similar-sounding domain names to confuse the users.
This particular version has also been found to activate a security bypass function — it will search for any active security programs and disable them. They can be anti-virus programs, firewalls, intrusion detection systems, and etc.
When the .cvc virus files are run on a given computer, the built-in action sequence will start. This is done using the common procedures as seen with previous Dharma ransomware versions. This will start with a data gathering procedure: this is used to hijack both users’ files and information from the operating system. This can potentially be used to identify the identity of the victims, as well as important information about the system. A generated hardware profile can be programmed to create a unique identifier (ID), it can be shown in the ransom note or be part of the extension applied to the hackers.
The .cvc virus can be used to carry out system changes, some of them may be the following:
- Persistent Boot Installation — This is a procedure that will automatically start the virus when the computer is powered on. It may also disable access to the recovery boot options, thereby making it very hard to follow most manual user recovery guides.
- Windows Registry Changes — The .cvc virus can modify the existing values found in the Windows Registry or create new ones for itself. This can lead to different types of issues for the criminals: the inability to launch certain services and applications, performance issues, data loss, and unexpected errors.
- Other Virus Installations — The .cvc Dharma virus can be used as a payload carrier for the deployment of other malware. Desktop threats will usually consider the installation of Trojan Horse clients — they are a very effective mechanism for causing damage to the hosts. They create a secure connection to a hacker-controlled server, thereby allowing the hacking group to take over control of the system, and also to steal user’s data.
When all modules have completed running, the final stage will be started. It will use a strong cipher to affect target users’ data. They will be governed by a built-in list of target file type extensions. They can be the following: multimedia files, backups, archives, documents, and etc. All of the affected files will be processed by a very strong cipher. The affected files will be renamed with the .cvc extension. A ransomware note will be created in folders where there are affected files. In some other versions, other signs of infection can also be created: wallpapers can be changed or lockscreens can be instituted. All of them will blackmail the victims to pay the hackers a quoted decryption fee.
