.a800 Ransomware – Distribution Techniques
The .a800 ransomware threat is a new sample release of the RotorCrypt malware family. It is designed to be distributed via different methods. We presume that the most popular ones are going to be used.
One of the most popular mechanisms is the coordination of email SPAM messages which aim to create impersonating letters that appear as being sent by legitimate and well-known companies, services and products. The recipients may receive messages that have the same design elements as the original emails. Using the stolen content the .a800 ransomware infections can happen when interacting with any one of them — banners, links, images, videos and etc. In some cases the virus files themselves can be directly attached to the messages.
The other popular strategy is to craft malicious web pages that pose as legitimate web sites that end users may frequently visit. This includes the likes of download portals, search engines, product landing pages and etc. As soon as they are opened links to the virus files may be presented either directly or through any of the posted content.
Most of the virus infections of this type are delivered via payload carriers of which there are two main types:
- Infected Documents — Dangerous macros that will trigger the ransomware infection can be embedded across all popular document formats: spreadsheets, text documents, presentations and databases. When such a file is opened the users may see prompt that asks them to enable the necessary scripts. The quoted reason is to enable the correct viewing of the file’s contents. As soon as the scripts are enabled the .a800 ransomware will be deployed to the infected machines.
- Application Installers — The other main type of payload delivery is the creation of infected software installers which are made by taking the legitimate files from their official sources and adding in the necessary code. The hackers will typically choose popular applications that the end users typically download: creativity suites, productivity and office apps, system utilities and even computer games.
The .a800 ransomware files can be spread on file-sharing networks as well which include BitTorrent. They are a popular outlet for serving both pirate and legitimate content, often the dangerous payloads are found there.
Large-scale infections can be caused by the use of browser hijackers. They are malicious plugins which are developed to be compatible with all of the popular web browsers. Most of them are uploaded to the relevant repositories using fake user reviews and developer credentials. The posted descriptions that advertise the plugins usually contain promises of new feature additions and performance optimizations. However as soon as they are installed not only the .a800 ransomware can be deployed, but also other major changes can occur. A popular strategy is to cause a redirect to a specific hacker-controlled page. This is made by changing the web browser settings: the home page, search engine and new tabs page. As this option depends on access to the browser it allows the criminals to also hijack data such as cookies, history, bookmarks and etc.
.a800 Ransomware – Detailed Analysis
The .a800 ransomware is a confirmed sample belonging to the RotorCrypt malware family. This is a well-known group of viruses that are known for assigning long extensions to the affected data and for having a modular framework allowing for various modules to be run in a succession or according to certain event triggers.
At the moment there is no information about the hacker collective behind the virus. We presume that this may be a non-experienced group as the RotorCrypt family of threats can be easily customizable. Customization services are widely available upon request on the dark web.
A complete code analysis was done on the collected samples showing that they are capable of interacting with the Windows operating system. An example is the removal of sensitive data — backups, shadow volume copies and restore points. This makes it very difficult to restore the infected systems without using a professional-grade data recovery solution.
The code analysis also shows that a persistent installation is made — this ensures that the .a800 ransomware engine will be started automatically when the computer is powered on. This disables access to the recovery boot menus which renders most manual user removal guides useless. In this case only the use of a quality anti-spyware utility can effectively remedy the infection.
Future releases might include other malicious actions as well:
- Information Harvesting — The .a800 ransomware can be configured to extract data from the infected computers that can reveal the identity of the victim users. This is done by programming the engine to look for specific strings in files data: a person’s name, address, interests and any stored account credentials.
- Machine ID Generation — An unique ID can be generated for every single infected computer. This is done by an algorithm that takes its input values from data sources such as the installed hardware components, user settings and operating system conditions.
- Additional Payload Delivery — Existing ransomware infections are useful for installing other threats including Trojans and miners.
- Windows Registry Changes — Many viruses have the ability to create, edit and remove strings from the Windows Registry. This can lead to very serious performance issues to the point of rendering the computers completely unusable. Changes to certain values can cause application errors, loss of data and unexpected behavior.
Users should know that .a800 ransomware virus files have the ability to hook up to existing processes and create ones of their own.
.a800 Ransomware – Encryption Process
Like other popular malware samples the .a800 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:
All affected files are renamed with the .a800 extension. A ransomware note will be produced in a text file called “recovery.instruction.txt” which reads the following:
