What is Wq2k ransomware? And how does it carry out its attack?

Wq2k ransomware is a file-encrypting virus discovered recently. It is a new variant of B2DR ransomware. Since it’s a newly discovered threat, malware researchers have yet to find a copy of this new B2DR variant to analyze its encryption method for flaws which is why it’s hard to tell yet if the files it encrypt are decryptable.

Once Wq2k ransomware carries out its attack, it drops its malicious payload in the system and connects it to a remote C&C server where it downloads its other malicious components. These malicious components are then dropped into several system folders and have their own tasks. Some are used for the data gathering module and stealth protection module while the others are used to modify important settings like the Windows Registry where it alters registry keys and sub-keys like Run and RunOnce. This allows the crypto-malware to run automatically on every system boot making it a persistent threat. After the system modifications, it scans the system looking for files with the following extensions:

.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

As usual, just like other variants of B2DR, Wq2k ransomware also uses the AES 256 encryption algorithm in encrypting the targeted files listed above. Once it completes encrypting them, it adds the .wq2k extension to each one of the files. It then releases its ransom note contained in a text file named “Readme.txt” that states:

“Your files were encrypted with AES-256.
