.UNNAMED Files Virus – Detailed Description

The .UNNAMED files virus is a dangerous new release that originates from the Kraken ransomware family. At the moment there is no information available about the hacking group behind it, we anticipate that they may be an experienced collective. As this is a custom version of a previously known threat it is possible that they have acquired the original code and modified it to produce the new iteration. The alternative is for the samples to be ordered from the dark underground markets where such services are often advertised.

These threats can be easily distributed to the target end users using a variety of methods. One of the most popular ones is the coordination of phishing attacks that take advantage of the fact that a large part of the recipients will interact with them. Their contents will include stolen or fake text and multimedia that impersonates famous companies and services. The .UNNAMED files virus can also be acquired from interaction with hacker-controlled sites that include such contents. They are hosted on addresses that sound very similar to the real sites. To make the victims interact with them the sites can include self-signed or stolen certificates.

The .UNNAMED files virus infection can be caused via the interaction with malicious files, two popular types are the following:

  • Infected Documents — These macro-infected documents will prompt the victims to enable the built-in code in order to display the contents correctly. When this is done the infection will be triggered. The dangerous fact is that they can take all popular file formats: text documents, spreadsheets, databases and presentations.
  • Setup Packages — The virus installation code can be placed in application installers of popular software — creativity suites, productivity apps, system utilities and even computer games.

These files can be uploaded to file-sharing networks like BitTorrent which are often used by computer users to share both legitimate and pirate contents. Many of the popular ransomware strains can be acquired by downloading and installing malicious plugins which are made for web browsers. They are often uploaded to their respective repository with fake user reviews and developer credentials. The posted elaborate descriptions may include long promises of new feature additions, videos and other contents.

The .UNNAMED files virus will probably feature the same behavior patterns as previous iterations of the ransomware family. The infections usually begin with a data harvesting engine which can gather information both about the victim users themselves and the machines. Using the collected machine details the algorithm can generate an unique ID that can be associated with the infected host. Any personal data about the users can be used for criminal activity like financial abuse and blackmail.

The data can be further used by another module called security bypass — it will scan the contents of the hard disk drive and memory in order to search for any programs that might interfere with the virus infection. They will be bypassed or entirely removed, depending on the instructions. Examples include anti-virus programs, virtual machine hosts, sandbox and debug environments and etc.

The .UNNAMED files virus can proceed with its many intended system changes such as the following:

  • Persistent Installation — This will manipulate the boot options in order to automatically start the ransomware when the computer is powered on. It can also disable access to certain recovery option thus making it very difficult to restore the computers.
  • Windows Registry Changes — The relevant engine can make the necessary modifications and edit existing values found in the Registry. It can alternatively also create specific ones for the virus. This will lead to data loss, unexpected errors, performance issues and the inability to start certain functions.
  • Files Removal — The .UNNAMED files virus can be set to delete sensitive information from the system like archives, backups, shadow volume copies and restore points.

As soon as the .UNNAMED files virus files virus has completed running its intended malicious actions it will proceed with the actual file encryption procedure. It can commit itself to deploying various threats including Trojans and cryptocurrency miners. The ransomware will use a built-in list of target file type extensions that will be processed by a strong cipher: documents, multimedia files, archives, backups, databases and etc. All of the affected files will be renamed with the .UNNAMED extension.

In the end of this process a ransomware note will be produced in a file called UNNAMED-DECRYPT.txt which will manipulate the readers into paying the hackers a decryption fee.
