.cbtl Ransomware – Distribution Techniques
The .cbtl ransomware threat has just been discovered during an ongoing attack campaign. It appears that the captured samples are early test releases as the infected machines are relatively low in number. We anticipate that future attacks will use the most common tactics.
One of the most common mechanisms used to spread viruses is to employ email phishing messages which are sent to the victim recipients in large volumes. They are designed to impersonate well-known companies or services that the users may know and use. By interacting with the built-in content or attached files the .cbtl ransomware can be delivered to the targets.
The hackers can create malicious web sites that attempt to replicate the home pages, product landing pages, search engines and download portals that are frequently accessed by users. Upon interacting with the web content the .cbtl infection can happen, all kinds of user interaction can lead to this: web banners, pop-ups, links, ads and etc.
Most of the virus infections of this type are made via opening up dangerous payloads — modified virus files that are usually one of these two categories:
- Documents — The hackers can embed the virus infection scripts in documents across all popular file formats: presentations, rich text documents, databases and spreadsheets. Whenever they are opened by the victims a prompt will be spawned asking for the macros to be executed. If this is doen the infection will follow.
- Installers — The criminals can also create malicious versions of popular software that is often downloaded by end users. Usually the list includes the likes of creativity suites, productivity and office applications, system utilities and etc.
The files can be spread through file sharing networks like BitTorrent which are popular for spreading pirate and legitimate content.
The hackers can also choose to create browser hijackers that represent hacker-made plugins for the most popular web browsers. They are usually uploaded to the relevant repositories with fake user reviews and developer credentials. The posted descriptions will promise new feature additions and performance optimization. If installed the users will infect themselves with the .cbtl ransomware. Other malicious actions that are effects of this behavior include the imposition of a hacker-controlled page as a redirect.

.cbtl Ransomware – Detailed Analysis
The .cbtl ransomware samples that were captured in the attack campaign are early test releases which appear to contain only the base ransomware engine. We anticipate that the most common malicious actions will be executed once a final verson of the virus is produced. A list of some of them is the following:
- Boot Options Modification — In order to make it very difficult active infections the hackers can modify boot options, configuration files, Windows Registry strings and other values in order to create a persistent infection. This means that the .cbtl ransomware engine will be started every time the computer is booted. In many cases this also makes it impossible to use manual user removal guides as they require access to boot options which are usually blocked.
- Data Harvesting — The engine can be programmed to harvest information that can directly reveal information about the users. This is done by searching for strings such as their name, address, phone number and any stored account credentials. If the .cbtl ransomware interacts with the Windows Volume Manager it can also hijack information from removable storage devices and available network shares.
- Machine Identification — An unique ID can be assigned to the compromised machines by using a built-in algorithm. It takes its input values from strings like the installed hardware components, certain user settings and operating system conditions.
- Windows Registry Changes — The engine can also be programmed to make changes to the Windows Registry by making new ones for itself or modifying already existing ones. This can affect the overall performance in a negative way by making the computers practically impossible to use. Services and applications can also behave in a non-intended way, produce errors, shut down unexpectedly and loss of data can also occur.
- Additional Payload Delivery — The .cbtl ransomware can also be used to drop other threats to the victim machines. Example threats include Trojans, miners, hijackers and etc.
As soon as addditional information is known about the .cbtl ransomware we will update this article.

.cbtl Ransomware – Encryption Process
Like other popular malware samples the .cbtl ransomware will launch the encryption engine once all prior modules have finished running. It will probably use a built-in list of target file type extensions which are to be processed by a strong cipher. An example list can include the following data types:
- Backups
- Databases
- Archives
- Images
- Music
- Videos
All affected files are renamed with the .cbtl extension. A ransomware note will be produced in an image or text file.
