This article provides information on how to remove easily RotorCrypt ransomware and how to restore .RAR files without paying the ransom.
Security researchers detected yet another version of RotorCrypt ransomware that is released in active attack campaigns. The threat encrypts files that store important information and appends the long extension !@#$_____ISKANDER@TUTAMAIL.COM_____$#@!.RAR to their names. Following encryption, the ransomware generated a ransom message to extort a ransom from victims.

RotorCrypt Ransomware – Distribution
To infect users, this new RotorCrypt ransomware strain may be spread via several different methods. Some of the main are:
- Spam email messages that aim to trick into downloading malicious file attachment or clicking malicious URL that causes a drive-by-download attack
- Fake software updates, Windows system activators, game key generators and other scams that are designed to execute the malicious code after you click on them
- Infected USB driver or other external drives
RotorCrypt (v .RAR) Ransomware – Overview
Security researchers detected yet another version of RotorCrypt ransomware that is released in active attack campaigns. The main trait of this new iteration is the specific extension it uses to mark encrypted files. When it encrypts a file it renames it with a long string of symbols followed by an email and the .RAR extension at the end.
However, data encryption is not the only impact caused by RotorCrypt ransomware. Before encryption stage, the threat needs to establish its malicious files on the system and plague essential system settings. So along with its payload, several other files may be dropped or created on the system. They may reside in some of the following system folders:
When all target files are encrypted and marked with the extension .RAR, the ransomware generates a ransom note file called INFO.txt to instruct victims how to obtain the specific decryption key. The message is short and presents text written in Russian. All that it reads is:
Для связи с нами используйте почту
Translated in English the message reads:
For communication with us, use the mail
It lefts basic questions unanswered including: how much is the ransom, how it should be transferred, is there any time frame after which the amount increases? Supposedly the ransom amount varies between $100 and $1000. In most cases hackers demand it to be transferred in Bitcoin cryptocurrency.
The good news for you is that the code of this nasty ransomware was cracked by security researchers so you don’t need to contact hackers either to transfer them the ransom. When you reach the guide at the end you will find out how to secure your PC and decrypt .RAR files.
RotorCrypt Ransomware – Encryption Process
Data encryption module of the .RAR variant of RotorCrypt ransomware is believed to be the same as those of its predecessors. This means that target files may be encoded with RSA cipher algorithm that is known to generate two keys – a public and a private. For the decryption, you should have the private key. After the ransomware encrypts the last target file it sends the key to a remote server controlled by hackers. Happily, there is no need to worry that you don’t have this key. As mentioned in the previous paragraph at the end of our guide you will find a free decryption solution for all your .RAR files.
As regards the files which the .RAR version of RotorCrypt encrypts they are reported to be the following:
.1cd, .avi, .bak, .bmp, .cf, .cfu, .csv, .db, .dbf, .djvu, .doc, .docx, .dt, .elf, .epf, .erf, .exe, .flv, .geo, .gif, .grs, .jpeg, .jpg, .lgf, .lgp, .log, .mb, .mdb, .mdf, .mxl, .net, .odt, .pdf, .png, .pps, .ppt, .pptm, .pptx, .psd, .px, .rar, .raw, .st, .sql, .tif, .txt, .vob, .vrp, .xls, .xlsb, .xlsx, .xml, .zip
The ransomware follows specific pattern that includes four symbols, a contact email address and the extension .RAR at the end. For example if you have saved a file with the name lifegoal.docx following encryption the ransomware will rename it to lifegoal.docx!@#$_____ISKANDER@TUTAMAIL.COM_____$#@!.RAR
