What is Crypt888 ransomware? And how does it carry out its attack?
Crypt888 ransomware is a malicious program that encrypts files to extort money from its victims. This ransomware was first discovered way back in June last year but apparently is now back with a vengeance as it was spotted having new distribution campaign that seems to mostly target users from Brazil. This updated version has done some changes to its code and uses redesigned ransom message and image in order to target new victims.
Crypt888 ransomware is also detected as Aviso ransomware or MIRCOP ransomware which encrypts victims’ files instead of placing them in a password protected archive file. Following its infiltration, Crypt888 may drop three malicious files named c.exe, x.exe and y.exe on the %Temp% folder. It also looks for the following file formats to encrypt:
.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .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, .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, .xqx, .zip.
After it’s done with the encryption, Crypt888 ransomware releases its ransom note which contains the following message written in Portuguese:
