Distribution of .tfudet Ransomware Virus
The so-called .tfudet ransomware is a devastating cryptovirus that has been recently released in attack campaigns against computer users worldwide. Threat actors could be utilizing widely used tactics of distribution to infect computer systems.
One of the methods that may be used by the malicious actors behind .tfudet ransomware includes the coordination of SPAM email messages — they are used to spread the threat by sending out messages that pose as legitimate notifications sent by popular Internet portals or services that the targets may use. The virus files can be either directly attached or linked in the body. They can also be uploaded to fake download sites which are designed to appear like any of the popular Internet portals or vendor download sites. The malicious actors may use similar sounding domain names, certificates and hijacked design and contents to coerce the victims into thinking that they are accessing the legitimate address.
Another way that the threat may spread is through infected payloads — the use of various files that are infected with virus code. A popular example is the malicious document which can take any form: presentations, rich text files, spreadsheets and databases. Once they are opened by the victims a notification message will pop-up asking the target users to enable the built-in scripts. If this is done the virus infection will follow. The other popular technique is the inclusion of the code in application installers. They are malicious copies of legitimate setup files of popular end-user programs that have been modified with the .tfudet ransomware code.
Ransomware files are also popularly spread by fake user profiles — they can post to community forums or social media accounts. The criminals can utilize both fake or stolen identities to increase the number of infected users.
In certain cases, the criminals may also be distributed via malicious browser plugins — additions to the most popular web browsers that are advertised as useful. The plugins are uploaded to the official repositories and often make use of fake or hijacked user reviews and developer credentials. Once they are installed by the users they will execute their built-in instructions that in many cases leads to the .tfudet ransomware virus infection in the end.
Impact of .tfudet Ransomware Virus
As identified by security researchers .tfudet cryptovirus is a strain of the infamous STOP ransomware family. Analyses of its samples reveal that it acts like a typical data locker ransomware as it contaminates system settings in order to encode targeted types of files and extort a ransom free for their decryption.
Even if .tfudet ransomware virus does not render your PC inoperable, it applies a lot of modifications that disrupt system security.
Once execution of .tfudet ransomware’s payload on the system is fact, the threat becomes able to proceed further with sequent infection stages. Since the completion of the attack is possible only with the help of additional malicious files, the ransomware initiates their establishment. It could be set to either create or drop them on the system. As locations, .tfudet may choose the following system folders – %Roaming% , %Windows% , %AppData% , %Local% , %Temp%
After this step, the threat starts executing them in a predefined order. This, in turn, results in heavy system settings modifications. Affected could be keys from the Registry Editor, legitimate processes and other essential components.
Following system corruption, .tfudet ransomware utilizes a built-in encryption module to mark the beginning of the main infection stage – data encryption. Since this module is designed to transform the code of targeted files with a sophisticated cipher algorithm, the last remain unusable until their code is reverted back to its original state.
Encrypted and as a consequence renamed with the extension .tfudet could be:
- Documents
- Archives
- Backups
- Databases
- Images
- Videos
- Music
At the end of the attack, .tfudet drops a text file with ransom message in it and loads it on the screen to inform you about its presence and impacts. This ransom message attempts to blackmail you into paying a hacker a ransom free, as well.
The good news for all of you who need to recover .tfudet files is that security researchers have managed to crack its code and released free decryption tool. So once you remove all malicious files and objects created from your infected system you don’t have to pay hackers for your files. Instead you could download the decryption tool and start the recovery process. Beware that you should first back up all encrypted files to an external drive. Otherwise, you risk their irreversible loss.
Note!
The same decryption tool is also working for STOP ransomware versions .puma, .pumax, .pumas, .djvu, .djvuq, .djvur, .djvut, .djvuu, .pdff, .tfude, .tfudeq, .tro, and .udjvu
Remove .tfudet Ransomware Virus and Restore PC
Please note that paying the requested ransom fee to cybercriminals does not really solve your problem with .tfudet cryptovirus. In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.
WARNING! Manual removal of .tfudet ransomware virus requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage. If you don’t feel comfortable with manual instructions, download a powerful anti-malware tool that will scan your system for malware and clean it safely for you.
