What is XUY ransomware? And how does it execute its attack?

XUY ransomware is a data-encrypting malware designed to lock important data in a computer leaving them inaccessible to victims. This crypto-malware was discovered early November 2018. You can tell if your computer is infected by this threat when you see the .xuy extension appended to your files.
The instant it invades a computer, it immediately starts modifying the system in order to control the system processes. It modifies the Windows Registry so that it can run automatically whenever you start your computer, making it a persistent threat. XUY ransomware also utilizes several modules in its attack such as the data harvesting module and stealth protection module. The former is used to collect information in the computer while the latter is the one that uses the harvested data along with some malicious components in stopping any security programs from interrupting its attack. Once all the system modifications are carried out successfully, it scans the computer for files with the following extensions:
.accdb, .acl, .acrodata, .automaticDestinations-ms, .avi, .bmp, .cfg, .crl, .csv, .customDestinations-ms, .dat, .db, .db-journal, .dic, .db , .dll, .doc, .docx, .dot, .dotm, .dotx, .flv, .gif, .glox, .html, .info, .jpg, .js, .json, .library-ms, .lnk .log, .lst, .m4a, .mdv, .mkv, .mp3, .mp4, .mpt, .mydocs, .odp, .ods, .old, .one, .ots, .pbk, .pdf, .png, .pps, .ppt, .pptx, .pst, .rtf, .sol, .sqlite, .swf, .thmx, .txt, .url, .vssx, .wav, .xls, .xlsx, .xltm, .xltx, .xml, .xsl
After finding its targeted files, it encrypts them using a sophisticated encryption algorithm and adds the .xuy suffix to every encrypted file indicating that they can no longer be accessed. You will find out more about the attack once the encryption is done as XUY ransomware will open a program window which contains the following ransom note:

How does XUY ransomware proliferate over the web?
XUY ransomware proliferate using several methods but it mostly uses malicious spam email campaigns. Cyber crooks tend to attach infected files in emails and disguise them to trick users in opening the email and downloading the infected attachment. This is why you have to double check the email before you download the attachment. It would also be better if you keep both your security programs and system up-to-date to avoid dangerous cyber threats like XUY ransomware.
