What is Ke3q ransomware? And how does it execute its attack?

Ke3q ransomware is a newly spotted data-encrypting virus that happens to be the latest variant of B2DR ransomware. This new B2DR variant uses a “.ke3q” suffix to mark the files it encrypts. Based on the analysis done by security researchers, there are no distinguished changes in this new B2DR strain, save for the extensions it uses and its ransom note.

Ke3q Ransomware

During the execution of its attack, the crypto-malware is launched in the system using a malicious executable file. This executable file is also responsible for connecting the infected computer to a remote C&C server where it downloads more malicious files. These other malicious files are dropped in the system folder and programmed to stop any programs installed in the system from impeding its attack. These files are also set to modify the Windows Registry, particularly the RunOnce sub-keys to make sure that Ke3q ransomware can run on every system boot. After these alterations, it will begin to look 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

Ke3q ransomware uses the AES encryption algorithm in encrypting its targeted files just like its predecessor. After it completes encrypting them, it adds the “.Ke3q” suffix to each one of the compromised files. It then releases its ransom note contained in a text file named “Readme.txt” that states:

“HOW TO GET MY FILES BACK?

If you are one of the unfortunate users who have fallen victim to Ke3q ransomware, contacting them to pay the ransom is certainly not recommended as these crooks are not really known to keep their promises to their victims once they get what they want. Thus, the best way to deal with this threat is to eliminate it from your computer immediately.

How is the malicious payload of Ke3q ransomware disseminated online?

At the time of writing, it isn’t clear how the malicious payload of Ke3q ransomware is disseminated online. However, it could employ malicious spam emails where a corrupted link or file is attached. These infected files are mostly documents with macro scripts which are used to execute some commands to download and install B2DR ransomware into the system. These documents are usually disguised as receipts, invoices, and other seemingly important documents so you need to beware of such tactics used by cybercrooks these days.

To eliminate Ke3q ransomware from your computer, use the removal guide as a reference.
