What is .twist File Extension ransomware? And how does it execute its attack?

.twist File Extension ransomware is an encryption ransomware Trojan which was first spotted in the final weeks of February 2018. This ransomware is created using the HiddenTear open source platform. Once this crypto-malware infiltrates a system, it does not rush its encryption instead it modifies and creates entries in the Registry to achieve persistence. Aside from that, it also injects malicious code into various system processes and installs additional malicious files to perform other malicious tasks in the system.

This HiddenTear variant uses a strong encryption algorithm in encrypting different kinds of files that contains these 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

During the encryption process, .twist File Extension ransomware uses the AES 256 encryption algorithm in encoding its targeted file extensions. As you can see on the list above, this ransomware mostly targets user-generated files while avoiding the ones from Windows system as they want the victims to still be able to connect to the internet and use the infected PC to send a ransom payment in exchange for the decryption key needed to decrypt the files.

.twist File Extension ransomware displays a simple and short ransom note in a file named How_Decrypt_Files.txt that states:

“Hello !

All your files have been encrypted !

If you want to restore your files write on email – twist@airmail.cc

In the subject write -id-[redacted]”

Paying the ransom should not be part of your recovery solution as there really is no guarantee that the crooks behind .twist File Extension ransomware will do their end of the bargain once they receive the ransom payment. Usually, victims of ransomware threats are ignored by crooks that had successfully deceived them into paying the ransom.
