Terminating Badfail@qq.com Ransomware (Crypto-Malware/Ransomware)

What is [email protected] ransomware? And how does it execute its attack?

[email protected] 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, [email protected] 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 [email protected] 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. The best course of action to take is trying out other alternative ways in recovering your encrypted files but before you do that, you need to terminate [email protected] ransomware from your system.

You should know better than to open these kinds of files, especially if the email is full of grammatical errors. To avoid getting infected with ransomware threats again, delete any suspicious-looking emails from the moment you notice one in your inbox.
