.RT4BLOCK Files Virus – Detailed Description
As the .RT4BLOCK Files Virus is descendant from the RotorCrypt ransomware we expect its samples to be spread using several of the most popular methods at once. One of the main tactics used by hackers is to prepare phishing email messages or construct such phishing sites. They are modeled to appear as legitimate companies or services urging the recipients into interacting with the content — clicking on links or downloading software. Such behavior will trigger the virus delivery.
The virus infections can also be caused by interaction with malicious files. They can take the form of macro-infected documents which can take all popular formats: presentations, text documents, databases and spreadsheets. When they are opened the users will be asked to enable the built-in scripts, if this is done the .RT4BLOCK Files Virus infection will begin. The other alternative is to create malware setup packages of popular software. They are made by taking the legitimate installers from their official sources and modifying them to include the virus code.
These files can also be uploaded to the relevant file-sharing networks such as BitTorrent where both pirate and legitimate data can be acquired.
Following previous versions of the RotorCrypt family we anticipate tha large-scale infections can also be done by the interaction with malicious web browser plugins. The hackers use phishing strategies in order to lure in more visitors into installing them. This is done by posting an elaborate description with fake user reviews and criminal credentials.
Due to the fact that this virus is a variant of the RotorCrypt ransomware we anticipate that the most common malware actions will be run prior to the actual file encryption. A list of the most popular modules is the following:
- Persistent Installation — The .RT4BLOCK Files Virus can be installed as a persistent threat meaning that the engine will edit the boot options in order to automatically start as soon as the computer is powered on. It can also disable access to the recovery boot options thereby making it very diffcult to follow most manual user removal guides.
- Security Bypass — The .RT4BLOCK Files Virus can search for any security software that can block the proper delivery of the threat. The list of the target applications includes the following: anti-virus programs, sandbox environments, virtual machine hosts and etc.
- Information Harvesting — The .RT4BLOCK Files Virus can include a data harvesting module which can hijack user information and machine metrics. This is done by programming the engine to look for specific strings in memory and on the hard disk drive. The collected information can be used for identity theft and financial crimes. The machine information can be used to generate an unique ID for every infected host.
- Windows Registry Changes — If the .RT4BLOCK Files Virus include this functionality then the engine can edit or create new strings in the Windows Registry. This can lead to data loss, system issues and the inability to access certain functions.
When everything has completed running the encryption phase will run. As a RotorCrypt variant it will follow a built-in list of target file type extensions: archives, multimedia files, documents, backups, databases and etc. When the processing has completed the victim files will be renamed with the .RT4BLOCK extension, the associated ransomware note will be crafted in a file called NEWS_INGiBiToR.txt.
.RT4BLOCK Files Virus – What Does It Do?
The .RT4BLOCK Files Virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.
You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.
The .RT4BLOCK Files Virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
