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

Sguard ransomware is a dangerous file-encrypting virus that can corrupt important data in a computer. It is designed to encrypt files and demands a ransom worth €600 in Bitcoins. According to researchers, this new crypto-malware is a new variant of GarrantyDecrypt ransomware. It uses a “.sguard” extension in marking its encrypted files and seems to follow the same pattern as other variants of GarrantyDecrypt.

The moment Sguard ransomware infiltrates the system, it connects it to a remote server. After that, it creates and downloads more malicious files and places them on system folders. It then proceeds to make modifications in the Windows Registry by modifying some existing registry keys like RunOnce as well as create new ones to allow it to run on every system boot automatically. It also employs two modules namely, data harvesting and stealth protection modules. The first module is used to gather information from the computer and use it for the second module which is the one that bypasses any security programs installed in the system that could interfere with the attack. 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

After finding its targeted files, Sguard ransomware encrypts them AES cryptography. Following its encryption of the files, it appends .odin extension in every compromised file. You will then see a text file named “SGUARD-README.txt” which contains the following content:
