What is Xorist-XWZ ransomware? And how does it execute its attack?
Xorist-XWZ or XWZ ransomware is a file-encrypting threat designed to lock files in an infected system. This new crypto-malware is actually a new variant of the infamous Xorist ransomware. It was first spotted on March 20, 2018, after some users reported finding their files with the “.xwz” extension which is it is named as “Xorist-XWZ” ransomware.
Once Xorist-XWZ ransomware is activated on a targeted system, it adds more malicious files to help it execute its attack – some of which are created by the ransomware itself while others are downloaded from its Command and Control server. After it successfully drops these files in the essential Windows system folders, it might also create and alter some Registry entries so it can run on every system startup. Following the modifications in the registry, Xorist-XWZ ransomware will scan the entire computer drive to look for files to encrypt. According to researchers, it still targets the same file types like all the other variants of Xorist ransomware such as:
.1cd, .3gp, .7z, .a06, .ac3, .aleta, .aol, .ape, .arena, .aspx, .avi, .b64, .bak, .bd, .bmp, .cdr, .cer, .csv, .dat, .db, .dbf, .divx, .djvu, .dl0, .dl1, .dl2, .dl3, .dl4, .dl5, .dl6, .dl7, .dl8, .dl9, .doc, .docx, .dwg, .flac, .flv, .frf, .gdb, .gif, .gzip, .htm, .html, .ibk, .ifo, .jpeg, .jpg, .kwm, .ldf, .lnk, .m2v, .max, .md, .mdb, .mdf, .mkv, .mov, .mp3, .mp4, .mpeg, .mpg, .mt0, .mt1, .mt2, .mt3, .mt4, .mt5, .mt6, .mt7, .mt8, .mt9, .net, .odt, .p12, .pdf, .pfx, .png, .ppt, .pptx, .ps1, .psd, .pwm, .rar, .sql, .tar, .tib, .torrent, .txt, .vhd, .vhdx, .vob, .wallet, .wav, .wk0, .wk1, .wk2, .wk3, .wk4, .wk5, .wk6, .wk7, .wk8, .wk9, .wma, .wmv, .xls, .xlsm, .xlsx, .xml, .zip
Xorist-XWZ ransomware uses the AES encryption algorithm in encrypting files. As soon as it finishes the encryption, it will begin to append the .xwz extension on every encrypted file then deliver a ransom note in a text file named “READ ME FOR DECRYPT.txt” that contains the following message:
“All your files is encrypted using an unknown algorithm!
Do not try to decrypt manually!
You can destroy your files!!
