What is Rapid ransomware? And how does it carry out its attack?
A new Rapid ransomware variant was released recently which uses the .RPD extension in marking its encrypted files. This new malware strain follows the Rapid 3 variant which was released not too long ago in May 2018. Just like its predecessor, this new variant will drop its malicious payload in the system and downloads more malicious files and drop them into system folders. This allows Rapid ransomware to launch and repress processes in the Windows environment. In addition, it also alters some registry keys and sub-keys which allows it to run automatically on every system boot.
After the changes are applied, Rapid ransomware scans the computer for the very same files which have 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
Once it finds files with the extensions listed above, Rapid ransomware will begin the encryption process by applying the AES encryption algorithm. After the encryption, it adds the .RPD suffix to each one of the compromised files. It then displays its ransom note stating:
“[ RAPID RANSOMWARE ] Hello, dear friend!

If you are one of the unfortunate users who got infected with this new Rapid variant, you must not follow the instructions on its ransom note as it could only lead you to the crooks behind this threat, which will demand a huge ransom from you. The best way to deal with this kind of threat is by killing its processes and malicious components from your computer and try alternative ways to recover your files.
How is the malicious payload of Rapid ransomware distributed?
Like other Rapid variants, the malicious payload for this one might also be distributed using malicious spam email campaigns.
