What is Fast_Decrypt_and_Protect@Tutanota.com ransomware? And how does it implement its attack?
Fast_Decrypt_and_Protect@Tutanota.com ransomware is a crypto-virus that belongs to the infamous Xorist ransomware family. Its primary goal, like its predecessors, is to encrypt certain files in an infected computer to extort money from victims. This crypto-virus was first released in 2016 and was once again seen out in the wild as of late. It uses both the XOR and TEA encryption algorithms in locking its targeted files and adds the “.firstname.lastname@example.org” extension to the files it manages to encrypt.
Once its malicious payload is executed, Fast_Decrypt_and_Protect@Tutanota.com ransomware will start to implement its attack by adding more malicious files to stop any programs installed in the system from interfering with its attack. It also creates and modifies Registry entries so it can run on every system boot. After these changes are made, it will begin the encryption process which might affect files with the following formats:
.1cd, .3gp, .7z, .a06, .ac3, .aleta, .aol, .ape, .arena, .aspx, .avi, .b64, .bak, .bd, .bmp, .cdr, .cer, .csv, .dat, .db, .dbf, .divx, .djvu, .dl0, .dl1, .dl2, .dl3, .dl4, .dl5, .dl6, .dl7, .dl8, .dl9, .doc, .docx, .dwg, .flac, .flv, .frf, .gdb, .gif, .gzip, .htm, .html, .ibk, .ifo, .jpeg, .jpg, .kwm, .ldf, .lnk, .m2v, .max, .md, .mdb, .mdf, .mkv, .mov, .mp3, .mp4, .mpeg, .mpg, .mt0, .mt1, .mt2, .mt3, .mt4, .mt5, .mt6, .mt7, .mt8, .mt9, .net, .odt, .p12, .pdf, .pfx, .png, .ppt, .pptx, .ps1, .psd, .pwm, .rar, .sql, .tar, .tib, .torrent, .txt, .vhd, .vhdx, .vob, .wallet, .wav, .wk0, .wk1, .wk2, .wk3, .wk4, .wk5, .wk6, .wk7, .wk8, .wk9, .wma, .wmv, .xls, .xlsm, .xlsx, .xml, .zip
Following data encryption, Fast_Decrypt_and_Protect@Tutanota.com ransomware drops its ransom note contained in a file named “HOW TO DECRYPT FILES.txt” that states:
“All your important files were encrypted on this computer. You can verify this by click on see files an try open them. Encryption was produced using unique KEY generated for this computer.

The single copy of the private key, with will allow you to decrypt the files, is located on a secret server on the internet; The server will destroy the key within 24 hours after encryption completed. Payment has to be made in maxim 24 hours. To retrieve the private key, you need to pay 3 BITCOINS.
Bitcoins have to be sent to this address:
After you’ve sent the payment to send us to email to email@example.com with subject: ERROR-ID-random(3BITCOINS). If you are not familiar with bitcoin you can buy it from here: SITE: www.localbitcoin.com.
After we confirm the payment, we send the private key so you can decrypt your system.”
