Distribution of .PHOBOS Virus

The .PHOBOS virus is a new malware threat which at the moment has been spotted in a very limited attack wave. Due to the yet unknown criminals behind its launch the security experts cannot deduce which is the primary distribution method. As such we suspect that the most popular strategies are going to be employed.

One of them relies on creating email messages in an automated way which all deliver the .PHOBOS virus to the targets. A common way of doing this is by attaching the strains directly to the messages. This is one of the easiest way for the criminals to attempt the infection. However a lot of email hosting providers usually capture the signatures of the virus and as such discard such messages or label them as dangerous or spam. Other infection methods related to this one is the option of inserting hyperlinks in the body content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest. Redirects can redirect to hacker-controlled sites, infected payloads or other instances that can lead to an .PHOBOS virus infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the .PHOBOS 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 the .PHOBOS 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 addons 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 .PHOBOS Virus

At the moment the .PHOBOS virus is distributed in a very limited attack wave. The security researchers who are looking into the matter are not able to give out details on the identity of the hacker or criminal collective behind the malware. What is known is the fact that the .PHOBOS virus is made up of only a base ransomware engine. It is very likely that if the infections prove succesful the code will be updated by the hackers. The initial code analysis does not reveal a correlation with any of the popular malware families. This suggests that the virus has been developed from scratch by its creator.

Some of the updates that can be considered in future iterations include the following:

  • Persistent Installation ‒ This is a deep infection tactic which actively prevents manual removal attempts from the user’s part. When such a threat is involved in a computer attack the only way to effectively remove is by using a quality anti-malware solution.
  • Trojan Module ‒ It allows the hackers to remote control or spy on the users activities.
  • Data Theft ‒ The criminals can steal user files prior to the encryption phase.
  • Additional Virus Delivery ‒ The .locked virus can be used to install other viruses to the target machines as well.

If there are any predetermined conditions they are executed by the engine before the actual ransomware process is started. Like other similar malware the .PHOBOS virus uses a built-in list of target file type extensions. They usually contain the most popular data that uses utilize: documents, images, music, videos, archives, databases and configuration files. Depending on the case an exclusions list can also be implemented to exclude critical operating system components.

When the encryption process has completed all victim files will be renamed using the following template: ID[HEX].[

  • Hardware Components
  • Software Configuration
  • Individual User Settings
  • The email associated with the extensions can be changed to reflect the current contact address that are given to the criminal operators. When the string is constructed a ransomware note is created in a Phobos.hta file which reads the following:

    All your files are encrypted

    Hello World
    Data on this PC turned into a useless binary code
    To return to normal, please contact us by this e-mail: [email protected]
    Set topic of your message to ‘Encryption ID:6BBC6934’
