SIDENOTE: This post was originally published in April 2019. But we gave it an update in July 2019

The .bmn63 ransomware is a new sample release of a new malware family called Sodinokibi ransomware. According to the available information there is an ongoing wave of delivery campaigns using a variety of distribution methods.

The available code analysis reveals that the .bmn63 ransomware contains numerous dangerous components which are launched as soon as the infection is made. As soon as all components have finished in their prescribed order the actual file encryption operation will begin. Using a strong cipher sensitive user data will be processed according to the virus’s built-in instructions, usually a list of target file type extensions. The most common ones are to be encrypted: documents, music, videos, images, archives, backups and etc. All victim data is to be renamed with the .bmn63 extension. The associate ransomware note will be created in a file called bmn63-readme.txt. Take note that other similar strains of the same virus family may assign another extension. They may be randomly created extensions or assigned through a special algorithm.

.bmn63 Ransomware – Update July 2019

As this Sodinokibi virus can spawn numerous versions including the .bmn63 files virus has been found to be active in several attack campaigns. The hackers are sending in custom strains of the threat that once have infected the target computer have the ability to assign a custom extension. This means that several Sodinokibi virus iterations can be sent against the victims, each with their own custom configuration file.

What’s particularly worrying about this release is that every single derivative will create its own extension and possibly a ransomware note. One of the latest iterations have been spotted to be using a lockscreen instead of a ransomware note. This means that the victims will be unable to use their computers in the intended manner and only the use of a quality anti-spyware solution will help them recover their systems.

.bmn63 Ransomware — May 2019 Update

A new code code analysis of the threat captured in a recent attack campaign shows that the samples include an elaborate collection of dangerous modules. In order to hide the made changes to the system the main virus engine will suppress the errors and failures during the boot up procedures. This is often linked to boot modifications that start the virus engines as soon as the computer is powered on.

Access to certain operating system menus and options is also blocked — startup repair for example. This is done so in order to make it very hard to follow manual user removal guides. As part of the virus ransomware configuration it will also delete sensitive data, including volume snapshots and backups. Process lookup and hookups to the system will lead to the harvesting of the user interactions thereby making it possible to spy on the victims.

An advanced intrusion tactic used by the criminals is to delay the startup of the virus module after it has been deployed. This means that it will bypass the typical behavior scans employed by security software. Following the virus installation the threat will also read the system configuration and certain operating system variables in order to search for the presence of such security software: anti-virus programs, firewalls, sandbox environments and intrusion detection systems.

To make it more difficult the virus engine will modify the operating system settings in order to redirect the Internet traffic through a hacker-controlled server. This will enable the hackers to spy on the victim’s activities in real-time. This behavior effectively allows them to acquire vast information without resorting to the deployment of a dedicated Trojan malware on the local machine. Coupled with the extensive gathering of data this ransomware proves to be a very dangerous threat. As soon as an infection has been detected it should be removed as soon as possible to prevent any extensive damage to the compromised machines.

.bmn63 Ransomware – How Does It Infect?

It is very likely that several distribution mechanisms are being used with it. A very common method is the orchestration of email phishing messages which are sent in a SPAM-like manner that imitates the design and contents of legitimate and well-known companies and services. Any interaction with them can lead to to the relevant infection. A related mechanism is the creation of malicious web sites that are made in a similar way. They are hosted on similar sounding domain names that resemble the pages of search engines, download portals, landing pages and etc.

The virus infection code can also be found within payload carriers such as malware documents that can be of all popular formats: databases, spreadsheets, text documents and presentations. The built-in macros will launch the virus installation as soon as the users interact with them. The other popular carrier is the creation and distribution of application installers that are virus-infected copies of setup files for programs like utilities, productivity tools and creativity suites.

All of these files can also be spread via file sharing networks such as BitTorrent where all sorts of data is shared — both legitimate and pirate files. The virus installation may also be made via browser plugins which are malicious in nature, they are also called hijackers and they are spread on the relevant repositories. Usually this is done with fake user reviews and developer credentials in order to coerce as many victims as possible to download it.

.bmn63 Ransomware – What Does It Do?

The available code analysis reveals that the .bmn63 ransomware contains numerous dangerous components which are launched as soon as the infection is made. Coupled with the large-scale distribution campaign we anticipate that the criminal collective is experienced. One of the first actions that are undertaken by the criminals is to lead to serious system changes which includes a wide range of actions. It can list all running processes, create files and processes of its own and additionally modify operating system related data. The analyzed information can be scanned for the presence of any security software which can block the proper running of the application bypass will scan for software like anti-virus programs, firewalls, sandbox environments and etc.

In order to facilitate a much more dangerous infection the virus engine can also renamed user data and delete or corrupt the automatic backups made by the operating system. Through interaction with the operating system services the ransomware may delete entries found within the Windows Registry and edit user preferences. Future versions can lead to other dangerous behavior such as the following:

  • Persistent Infection — The .bmn63 ransomware can be set to automatically start as soon as the computer is launched. This will make it very difficult to interrupt the malware processes and also in many cases this will disable access to the relevant recovery processes. This will render many manual user removal guides non-working.
  • Additional Malware Delivery — The ransomware can be used to deploy other threats to the system including Trojans, hijackers, miners and etc.

Any future releases can lead to the inclusion of further modules.
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 .bmn63 Ransomware 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
