What is Guarded ransomware? And how does it implement its attack?

Guarded ransomware is a dangerous crypto-malware infection that can corrupt important data in a computer. According to security experts, it is a new and improved version of Sguard ransomware. This new malware strain appears to still follow the same pattern in implementing its attack. It uses a “.Guarded” extension to mark all the files it has managed to encrypt.
It starts to implement its attack by connecting to a remote server where it downloads its other components and places them on several system folders. These components allows the crypto-virus to launch or repress system processes. Using these components, it also employs a data harvesting module which gathers information from the system. The obtained information is processed and used for the stealth protection module which allows the crypto-virus to bypass security programs, virtual hosts, antivirus programs and sandbox environment that may interrupt the attack. To make its removal difficult, Guarded ransomware also alters some entries in the Windows Registry, allowing it to carry out its attack automatically in every system boot. Once it achieved in modifying essential system settings, Guarded ransomware will begin scanning the system for files with the following extensions:
.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
The instant Guarded ransomware locates these files, it encrypts them using the AES cipher. Following its encryption of the files, it appends .Guarded extension in every compromised file. You will then see a text file named “GUARDED-README.txt” which contains the following content:

How does Guarded ransomware spread online?
Guarded ransomware could spread online in various ways. It may spread via a payload dropper that initiates the malicious script used for the crypto-virus to run in the system. It might also spread by hacking into unprotected RDP configuration, exploit kits and fake software update which is why you must always keep your computer protected by constantly updating the system and all the antivirus and security programs installed in it.
