What is XiaoBa ransomware? And how does it execute its malicious attack?

XiaoBa ransomware a file-encoding Trojan infect set to encrypt the important files in a targeted system. As it names suggests, this crypto-malware is created by Chinese cyber criminals and was recently discovered in the last week of February 2018. According to the analysis done by security researchers, XiaoBa ransomware seems to be combined with a Chinese ad-supported program or adware called FlyStudio. In other words, it spreads using an adware program.
The moment XiaoBa ransomware enters a targeted machine, it will begin its search for certain file types to encrypt. It is set to encrypt files with the following extensions:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2
Using the RSA 2048 and AES 128 encryption algorithm, it encrypts files and appends the [[email protected]].XiaBa extension on each one of the files. After the encryption, XiaoBa ransomware will display its ransom note which is written in Chinese that states:
“Ooops, your important files have been encrypted!
—— 重要加密 ——

This crypto-malware demands $38 up to $180 from its victims for the decryption software. Note that this ransomware deletes the shadow volume copies of your files so it would be hard for you to recover them using the Windows Previous version feature. Nonetheless, that doesn’t mean that you should purchase the decryption software from the crooks. in fact, doing so won’t be a wise move since there really is no guarantee that the crooks will give you the decryption software once they receive the payment.
