Distribution of Katafrack Virus

The Katafrack Virus is a new virus which has been sighted in a limited attack campaign. At the moment the security researchers cannot determine the primary infection strategy. We presume that the most widely used tactics are going to be employed.

Among them are the email messages created in an automated way and sent to large lists of potential victims. The Katafrack Virus can be directly attached 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 Katafrack Virus infection.

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

The latest Ordinal strain has been detected as the Katafrack virus. The original code of the Ordinal malware family is based on the open-source Hidden Tear project. They both represent some of the most widely used hacker tools. The Hidden tear code is widely used by beginner hackers and criminals as there are hundres of tutorials and guides that give details on customizing the code.

The base engine is entirely modular and the virus engine can be updated at any time if such a component is found. The initial security analysis shows that it is a reconfigured versiion of certain Ordinal ransomware strains. The experts note that there are some initial defensive options included that guard the malware Katafrack virus from discovery by virtual machines, sandbox and debugging environments.

The criminals can customize the Katafrack virus by including additional components such as the following:

  • Additional Malware Delivery ‒ The Katafrack virus can be used to introduce other threats to the compromised machines as well.
  • Trojan Component ‒ Future Katafrack virus samples can include a Trojan module that gives the hackers the ability to spy on the users activities in real time, as well as record their mouse movement and keystrokes.
  • Code Execution ‒ The hackers can program the Katafrack virus to execute various malware code on the compromised machines either automatically upon infection or when certain conditions are met.
  • System Changes ‒ Any changes made to the machines can result in performance issues, application failure or the inability to start certain functions.
  • Persistent Installation ‒ The Katafrack virus can be installed in a way which counters manual user removal attempts.

Once all prerequisite steps have been complete the ransomware component is launched. It starts to encrypt target file type extensions based on a list of target file type extensions. In the most popular case this includes files such as: images, videos, archives, documents, music, backups, databases and configuration files. The ransomware note is generated in a file called READ-ME-TO-GET-YOUR-FILES-BACK.txt which reads the following:

Your files have been encrypted by Ordinal Ransomware
Below is the information you will need to decrypt your files
After that, you’ll be able to see your beloved files again.

ETH Address 0x06394880c86383eccFbf27788D578C46ed562526
Amount To Send: 0.02 BTC

As it is a more or less copy of the Ordinal ransomware the hackers have distributed samples that contain the same ransomware message. Certain versions of the Katafrack virus can also include a dangerous lockscreen instance that prohibits ordinary use of the computer until the malware is completely removed. Here is an example message:

Follow the instructions to unlock your data
All your files have been encrypted with AES-256 Military Grade Encryption
Your files have been encrypted, the only way to recover your files is to pay the fee.
Once you have paid the fee all your files will be decrypted and return to normal.
Send the required fee (found below) to the Bitcoin address (found below). Once you have sent the required fee to the Bitcoin address send an email with your Identification key (without this we cant help you). It may take 12-24 hours for us to respond. You will recive a Decryption Program + Decryption Key. Ethereum is also accepted.

Depending on the version a ransomware note can be created which features generic messages blackmailing the victims to pay a Bitcoin ransomware fee. We recommend that all users abstain from communicating with the hackers and use our full Katafrack Virus removal guide below to recover their data and delete the active infections.
