What is Minotaur ransomware? And how does it carry out its attack?

Minotaur ransomware is a file-encrypting threat that was discovered in the first half of October 2018. It seems to be targeting English-speaking users but could also affect other users all over the globe. The instant it enters a targeted computer, it drops its malicious payload and connects the system to a remote server. After that, it creates and downloads more malicious files and places them on system folders.

Afterward, it proceeds to make modifications in the Windows Registry by modifying some existing registry keys like RunOnce as well as creating new ones to allow it to run on every system boot automatically. It then scans the computer for files with specific formats such as:

.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as.txt, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .dxf.c, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .zip

Once it finds the targeted files, it encrypts them using the AES encryption algorithm and appends the .lock extension. It then releases a text file named “How To Decrypt Files.txt” which contains the following message:
