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

XARCryptor ransomware is a crypto-virus discovered recently. It is reported to be the new variant of GarrantyDecrypt ransomware. Nothing much has changed in this new variant except for its ransom note and the extension it uses to mark its encrypted files which is “.odin”. Once XARCryptor 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, XARCryptor 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 “#RECOVERY_FILES#.txt” which contains the following content:

“All personal files on your computer are encrypted.

We STRONGLY RECOMMEND you NOT to use any decryption tools.

These tools can damage your data, making recover IMPOSSIBLE.
