What is CryptoManiac ransomware? And how does it perform its attack?
CryptoManiac ransomware is a file-encoding malware designed to encrypt files to leave them inaccessible to its victims. It demands victims to pay ransom in exchange for data recovery. It makes use of the AES cipher in corrupting its targeted files and insists on paying $500 in Bitcoins as soon as possible. Cybercriminals behind CryptoManiac ransomware encourage its victims to use the REQUEST RESTORE tool to recover their encrypted files.
CryptoManiac ransomware infects system through a file named CryptoManiac.py according to the analysis done by security experts. Various techniques could be used in distributing this malicious file. Once it reaches the targeted system, the malicious file will install CryptoManiac ransomware in the system and initiate a sequence of malicious operations to ensure persistence. After that, it scans the entire drive of the computer looking for files to encrypt. It most likely targets files with the following extensions:
.jpg, .jpeg, .raw, .tif, .gif, .png, .bmp, .3dm, .max, .accdb, .db, .dbf, .mdb, .pdb, .sql, .dwg, .dxf, .c, .cpp, .cs, .h, .php, .asp, .rb, .java, .jar, .class, .py, .js, .aaf, .aep, .aepx, .plb, .prel, .prproj, .aet, .ppj, .psd, .indd, .indl, .indt, .indb, .inx, .idml, .pmd, .xqx, .xqx, .ai, .eps, .ps, .svg, .swf, .fla, .as3, .as, .txt, .doc, .dot, .docx, .docm, .dotx, .dotm, .docb, .rtf, .wpd, .wps, .msg, .pdf, .xls, .xlt, .xlm, .xlsx, .xlsm, .xltx, .xltm, .xlsb, .xla, .xlam, .xll, .xlw, .ppt, .pot, .pps, .pptx, .pptm, .potx, .potm, .ppam, .ppsx, .ppsm, .sldx, .sldm, .wav, .mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa.wma, .ra, .avi, .mov, .mp4, .3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob, .m3u8, .mkv, .dat, .csv, .efx, .sdf, .vcf, .xml, .ses, .rar, .zip, .7zip, .jpg, .jpeg, .txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd
Once it is able to finish the encryption on the targeted files, it drops two different kinds of ransom notes but both have the same content such as:
All your files have been encrypted by CRYPTOMANIAC!
All your files have been encrypted due to a security problem with your PC.
