What is Matrix-THDA Ransomware?
Matrix-THDA Ransomware is a threat that drops a text file claiming the user’s files were encrypted because of some server vulnerabilities. The cybercriminals not only claim they can provide the necessary decryption key and decryption software but also offer to help the victim to secure the server/system. However, we would not recommend trusting them as no matter how friendly and polite the ransom note may appear to be, in reality, there are no reassurances they will hold on to their end of the deal. Therefore, what we recommend to those who encounter the malware is deleting it. We believe it is safer to recover files from backup copies. Not to mention, using backup files would be cost-free as Matrix-THDA Ransomware’s creators may ask for a ransom. If you want to learn more before coming up with a decision you should read the rest of this report. For those who have already decided we would suggest completing the steps listed below the article.
Where does Matrix-THDA Ransomware come from?
Matrix-THDA Ransomware could appear after opening an infected file, or it could be dropped on the system after exploiting the computer’s vulnerabilities like unprotected Remote Desktop Protocol connections. This is why our researchers at Anti-spyware-101.com advise taking all possible precautions to avoid receiving this threat. To begin with, you should watch out for malicious software installers and Spam email attachments. If you have doubts about the data’s security, you should always scan it with a legitimate antimalware tool just in case. Next, we advise removing possible system’s vulnerabilities, such as outdated software, weak passwords, and so on. Also, users should be careful when installing new software as it is both important to pick a reputable tool and download it from a legitimate source.
How does Matrix-THDA Ransomware work?
The user may not notice the malware is running and while being unseen, it should start encrypting users files one by one. Matrix-THDA Ransomware should target the victim’s personal files, e.g., pictures, photos, text or other documents, and so on. It is easy to separate affected files as all of them should have a new name and a particular extension (e.g., [FilesBack@qq.com].17vKnrMB-crt8aPoP.THDA). Clearly, the files left untouched would be the ones belonging to the computer’s operating system or other software. Otherwise, the device becomes unbootable, and the user would be unable to read the hackers’ ransom note. The cybercriminals call the malware “their automatic software” and use polite language in the note. Also, they give quite a lot of time (one week) to contact the Matrix-THDA Ransomware’s creators and a couple of options to do so. There is nothing said about paying a ransom, but you can understand you will be asked of it as the note says “We will definitely reach an agreement 
!!!” Sadly, even if these people sound polite and helpful in the end, they could scam you, and if you do not want to take any chances, we advise not to contact them.
