RotorCrypt (PATAGONIA92@TUTANOTA.COM) Ransomware – Infection Process
Another version of RotorCrypt data locker ransomware associated with the contact email PATAGONIA92@TUTANOTA.COM has been spotted by security researchers.
Once the threat is running on a computer system it initiates a sequence of modifications that enable it to plague main systems settings and remain undetected during the attack. Before it completes its main purpose which is data encryption, RotorCrypt ransomware creates additional malicious files needed for the successful attack.
Some of the files are designed to access the Registry Editor, add values under predefined sub-keys in order to utilize their functionalities. Most of times target sub-keys are Run and RunOnce. This is due to the fact that with the help of their functionalities the ransomware could run automatically all malicious files during the infection process. Furthermore, once the ransomware values are added under the Run sub-key, its malicious files are executed on each system start.
A ransom note file called HELP.txt could appear on PC screen immediately after data encryption. It is short and urges victims to contact a presented email address:

The good news is that there is no need to follow hackers’ instructions and worry about data decryption. Security specialists at Kaspersky had cracked the code of this nasty infection and released free decryption tool. Keep reading to learn more about it and how to use it.
RotorCrypt Ransomware – Encryption Process
This iteration of RotorCrypt ransomware has a built-in data encryption module that is believed to be operating in the same manner as the previous versions of the ransomware. Following a predefined encryption pattern, the threat encodes all target files with RSA cipher algorithm. During the encryption process, RotorCrypt generates two keys – public and private. Decryption is possible only with the help of the uniquely generated private key. In order that hackers could blackmail infected users into paying the ransom, their ransomware code transfers the private key to a remote server. Happily, there is no need to worry that you don’t have this key. Security specialists at Kaspersky successfully cracked the code of RotorCrypt ransomware. And at the end of our guide, you will find their free decryption tool that will help you to restore encrypted files.
As regards the types of files that could be encrypted by RotorCrypt they are reported to be:
.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
