Tfudeq Ransomware – Decryptor Released
Recently a series of new STOP ransomware variants have been released in active attack campaigns. As revealed by security experts, the main difference between newly discovered strains is the extension they use to mark corrupted files. Here you could see a list of all other extensions that testify for infection with a strain of STOP ransomware:
Happily, security experts have managed to crack the code of almost all variants of this ransomware family and released a decryption tool. So at this point only victims of .puma, .pumax and .pumas, .djvu, .djvuq, .tfudeq, .djvut, .tfudeq, .pdff, .tfude, .tfudeq, .tro, .udjvu, .tfudet STOP ransomware versions are able to decrypt their files with the help of the decryption tool created by the security researchers AfshinZlfgh and Michael Gillespie.
In case that you are victim of one of these versions you can download it via the Decryption Tool link. The tool requires a pair of an original file and its encrypted version.
Tfudeq Ransomware – Distribution Ways
The Tfudeq ransomware can be acquired through any one of the popular virus delivery tactics. Depending on the size of the campaign and the intended victims the criminal collective can choose to select one primary method or several ones at the same time. Usually virus samples are delivered by email SPAM messages which are made to resemble legitimate messages from well-known companies and services. The Tfudeq virus files can be linked in the body contents or attached directly to them.
The other popular method relies on the creation of malicious web pages that impersonate real-world software pages, company landing pages or download portals. They may include fake or stolen security certificates and similar sounding domain names to the legitimate addresses.
To make the attacks more successful the hacking collective can generate payload carriers which lead to the Tfudeq ransomware infection. There are two popular types which are popular with ransomware creators:
- Setup Files — The criminals can take the legitimate installers of popular end user software and modify them with the necessary instructions. They will lead to the Tfudeq ransomware deployment as soon as they are started. Most commonly this tactics is made with the most popular choices of end users: creativity suites, system optimization programs, productivity and office apps and etc.
- Infected Documents — They are made by inserting macros into documents of all popular types: spreadsheets, presentations, text documents and databases. Whenever they are opened by the users by the users they will be asked to enable the built-in macros in order to correctly view the contents. In other cases merely clicking on any of the interactive elements will trigger the Tfudeq infection.
All of these Tfudeq virus carriers can also be uploaded to file-sharing networks like BitTorrent which is one of the most popular platforms for spreading both legitimate content and pirate data. Larger attack campaigns can be made by configuring browser hijackers to infect the target computers. They are malicious browser plugins that are made compatible with the most popular web browsers. Usually they can be found on the relevant repositories with fake developer credentials and user reviews in order to coerce the target into believing that they are installing a useful addition that will add new features or provide performance enhancement.
Tfudeq Ransomware – In-Depth Overview
This particular sample belongs to the STOP ransomware family and as such can be configured to execute whatever behavior pattern the criminals intend to make. The modular architecture can be set to run both the default actions as exhibited by the previous STOP ransomware or a different infection mechanism. We assume that the first batch of the samples will continue to behave like the STOP ransomware that we are all accustomed to.
The infection usually begin with an information gathering module which is configured to harvest sensitive data from the system. The obtained data can be categorized in two main categories:
- Personal Information — This is data that can directly expose the identity of the victim users. This is done by configuring the engine to search for strings that reveal the victim’s name, address, phone number, location and any stored account credentials. As soon as the data sets are retrieved by the hacker operators they can be used for crimes such as identity theft and financial abuse.
- Machine Metrics — This group of data is useful for creating an unique infection ID that is assigned to each individual computer. It is composed by running an algorithm that takes many parameters in order to generate it: a list of the installed hardware components, user settings and current operating system variables.
The extracted information can be used to scan for the presence of any applications or services that can interfere with the correct infection. This security bypass can act against a wide range of engines: anti-viruses, firewalls, virtual machine hosts and intrusion detection systems.
When the engine has overtaken control of the target computer it will have the ability to hook up to various processes — both third-party applications and operating system services. This allows the virus engine to inspect the users activities in real-time. Various types of system changes will be executed after this step has completed. Most of them will access and edit the Windows Registry. This can be done against the values used by the operating system, the effects will be that the users may face serious stability problems to the point where the infected computers are unusable. Modifications to registry entries belonging to any third-party apps can make the stop running or frequently display unexpected errors.
If a persistent infection is made then the boot options and important system configuration files will be edited to start the Tfudeq ransomware each time the computer is powered on. This will also disable certain recovery boot menu options which will render many manual user recovery guides non-working.
Malware infections like the Tfudeq ransomware are popular devices for delivering co-infections — many of these samples can be configured to deploy other threats such as Trojans, miners and hijackers. Depending on the attack campaign, infected computers and other metrics the Tfudeq ransomware can act in different ways.
Tfudeq Ransomware – Encryption Process
What is known for the encryption process of the Tfudeq ransomware is that every file that gets encrypted will receive the .tfudeq extension. The encryption algorithms used to lock the files are AES and RSA 1024-bit.
The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The Tfudeq cryptovirus could be set to erase all the Tfudeq Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete Tfudeq /all /Quiet
In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.
