What is Tornado ransomware? And how does it implement its attack?

Tornado ransomware is a new crypto-malware designed to encrypt files to extort money from victims. As per the analysis done by security experts, it seems that this new crypto-malware is a new variant of InsaneCrypt ransomware. Its corrupted files can be recognized by the .tornado extension appended at the end of the affected files’ names. Once Tornado ransomware is able to infiltrate a targeted system, it will start to implement its attack by initiating a sequence of malicious actions. It will first connect to its Command and Control or C&C server in order to download additional malicious files it needs in its attack. These malicious files may be placed on essential Windows system folders like %AppData%, %Temp%, %Roaming%, %Common% and %System32%. After that, it will begin encrypting files using RSA encryption algorithm. According to researchers, it encrypts files with the following extensions:

.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2

Once it is done encrypting the targeted files, Tornado ransomware drops a ransom note on the desktop of the affected computer. The ransom note is contained in a text file named key.txt. Here’s the content of the ransom note:

“All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail: helpcrypt@airmail.cc.You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment, we will send you the decryption tool that will decrypt all your files.In case of no answer in 48 hours write us to these e-mails:

supphelp@cock.li

[redacted 512 hex]”

Paying the ransom is not recommended as you’d only end up losing your money so it is better to use other alternatives in recovering the encrypted files rather than negotiate with these crooks. Luckily, a decryptor is already made available by a security researcher named Michael Gillespie so there is no need for you to worry about a thing.

How does Tornado ransomware spread its malicious files?

Tornado ransomware spreads its malicious files via spam emails. The spam email may contain an infected email attachment that could be a macro-enabled document, an executable file, a PDF file or a link to the installer of Tornado ransomware. This is the reason why you shouldn’t just open any email that comes into your inbox, instead, you must carefully check if the email is worth opening or not as it may contain the malicious payload of Tornado ransomware and other similar threats.
