What is Badfail@qq.com ransomware? And how does it execute its attack?

Badfail@qq.com ransomware is another crypto-malware discovered on March 15, 2018. This new ransomware threat is a variant of Arrow ransomware, which, as it turns out, is a variant of Dharma ransomware. Based on the analysis done by security experts, Badfail@qq.com ransomware is not that different from its predecessors as there are only minimal changes to its code.

This crypto-malware will make modifications among Windows system files so it can obtain administrative privileges, the moment it enters the system. After that, it also alters the Windows Registry so it can run on every system boot. And once it accomplishes all these aforementioned modifications, it will begin its search for files to encrypt. According to researchers, it encrypts the following file types:

.gpx, .kml, .kmz, .asp, .aspx, .cer, .cfm, .csr, .css, .htm, .html, .js, .jsp, .php, .rss, .xhtml, .doc, .docx, .log, .msg, .odt, .pages, .rtf, .tex, .txt, .wpd, .wps, .csv, .dat, .ged, .key, .keychain, .pps, .ppt, .pptx, .ini, .prf, .hqx, .mim, .uue, .7z, .cbr, .deb, .gz, .pkg, .rar, .rpm, .sitx, .tar.gz, .zip, .zipx, .bin, .cue, .dmg, .iso, .mdf, .toast, .vcd, .sdf, .tar, .tax2014, .tax2015, .vcf, .xml, .aif, .iff, .m3u, .m4a, .mid, .mp3, .mpa, .wav, .wma, .3g2, .3gp

It encrypts its targeted files using the AEs encryption algorithm. Afterwards, it appends the .badfail@qq.com extension to each one of the files. Despite having your files encrypted, paying the ransom demanded by this ransomware is not recommended as it would only be a waste of money and time. Cyber crooks behind ransomware threats are not really known to keep their end of the bargain once they received the ransom payment.
