Distribution of .OBLIVION Ransomware Virus

.OBLIVION 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 .OBLIVION 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 .OBLIVION 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 .OBLIVION 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 .OBLIVION 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 .OBLIVION Ransomware Virus

The .Oblivion virus appears to be based on the Scarab malware family. It is possible that the attacks originate from a hacker or criminal group other than the original developer(s) of Scarab if the code has been shared on the underground markets or forums.

It is presumed that the attacks are customized to each campaign. The captured samples so far seem to be test versions. It is very likely that the upcoming attack campaigns would include updated versions.

The data harvesting engine can be started as the first component in the predefined chain of commands. It is programmed into harvesting sensitive data from the victim computers. It is usually classified into two categories:

  • Personal Data — The engine is programmed to extract strings that are used to extract the identity of the victims. Example contents includes the person’s name, address, telephone number, interests, location, passwords and account credentials.
  • Anonymous Metrics — The information is used for analytical purposes. It contains mainly operating system related strings and information about the available hardware components.

The collected information can be routed to the stealth protection. This part of the virus is used to protect it from applications or services that can intefere with its correct execution. Example targets are anti-virus products, sandboxes and virtual machine hosts. Some advanced viruses are configured to delete themselves if they are unable to bypass the applications.

Various system changes are used to modify the victim computers. Usually they affect the Windows Registry by modifying entries used by user-installed applications and the operating system. This can render certain features or whole applications practically unusable. This can cause severe performance issues as well. In combination with other modifications to the system startup the .Oblivion virus can be instituted as a persistent threat. This means that it will be started every time the computer boots.

The malware engine can delete the Shadow volume copies of sensitive data with the intent to make recovery more difficult. Advanced customizations can also employ a Trojan like behavior. This is done by connecting to a hacker-controlled server and allowing the hackers to spy on the victims in real time. The criminals have the ability to overtake control of the victim machines in real time as well as deploy additional threats.

As soon as all components have finished execution the ransomware module is started. It follows the typical behavior by using a built-in list of target file types that are encrypted with a strong cipher. An example list contains the following data:

  • Archives
  • Images
  • Databases
  • Music
  • Videos
  • Backups

As a result all victim files are renamed with the .OBLIVION extension. A ransomware note is crafted in OBLIVION DECRYPTION INFORMATION.TXT file which reads the following:
