What is M@r1a ransomware? And how does it implement its attack?

M@r1a ransomware, also known as .mariacbc Files Virus, is a data-encrypting malware that uses .mariacbc extension in marking the files it encrypt. Like other ransomware threats, M@r1a ransomware is designed to lock important files in a computer leaving them inaccessible to victims.

The instant it drops its malicious payload in the system, M@r1a ransomware will begin to implement its attack. It starts by connecting the system to a remote Command and Control server where it downloads its other components. After that, it gathers information about the victim and the system using a data gathering module. The information obtained is then used along with other components for the stealth protection module which is used to scan the system for digital signature of any security programs. In addition, it may also modify some entries in the Windows Registry so that it can run automatically on every system boot. Following these changes, it scans the system for files with the following extensions:

.3g2, .3gp, .7z, .accdb, .aes, .ARC, .asc, .asf, .asm, .asx, .avi, .backup, .bak, .bat, .brd, .bundle, .c, .cgm, .cmd, .cpp, .crt, .cs, .csproj, .csr, .csv, .db, .dbf, .dch, .der, .dip, .djvu, .doc, .docb, .docm, .docx, .dot, .dotx, .dwg, .edb, .eml, .flv, .frm, .gif, .gpg, .gz, .htm,.html, .hwp, .Iay6, .ibd, .iso, .jar, .jpeg, .jpg, .js, .jse, .key, .lay, .lbd, .log, .m2ts, .max, .mdf, .mdp, .mid, .midi, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .msg, .myd, .myi, .nef, .ocx, .odg, .odp, .odp, .ods, .odt, .onetoc2, .ost, .otg, .otp, .ott, .PAQ, .pas, .pdf, .pern, .pfx, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .pst, .pub, .py, .pyc, .pyd, .pyo, .rar, .raw, .rm, .rpa, .sb2, .sch, .sh, .sin, .sldm, .sldx, .slk, .snt, .sql, .sql, .sqlite3, .sqlitedb, .stc, .std, .sti, .stw, .suo, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .tbk, .tiff, .txt, .uop, .uot, .vb, .vbe, .vbproj, .vbs, .vcd, .vdi, .vdmk, .vmx, .vob, .vsd, .vsdx, .wks, .wma, .wncry, .wrav, .xdata, .xlc, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .zip

Once it finds its targeted files, M@r1a ransomware encrypts them using the AES 256 encryption algorithm and after file encryption, it adds the .mariacbc extension to every encrypted file. It also opens a GUI interface window which contains the following content:
