What is Cryptotes ransomware? And how does it carry out its attack?

Cryptotes ransomware is one of the latest crypto-virus discovered early in February 2019. After security experts analyzed the source code of this crypto-virus, it was found that Cryptotes ransomware is a new variant of Rotorcrypt ransomware. Nothing much has changed in this new variant as it still target files with the following extensions:

.csv, .doc, .ppt, .xls, .avi, .bak, .bmp, .dbf, .djvu, .docx, .exe, .flv, .gif, .jpeg, .jpg, .mdb, .sql, .mdf, .odt, .pdf, .png, .pps, .pptm, .pptx, .psd, .rar, .raw, .tif, .txt, .vob, .xlsb, .xlsx, .zip

The only notable difference between this new Rotorcrypt variant and its predecessors is that it uses .cryptotes extension in marking the files it encrypts. It still follows the same sequence of attack once it infiltrates a computer. It employs a data harvesting module used to gather data from the compromised system. The data harvested is used for the stealth protection module which is the one that bypasses any security programs installed in the computer and disables or removes them to prevent them from interfering with the attack. Moreover, Cryptotes ransomware also modifies some entries in the Windows Registry like the Run and RunOnce keys in order to automatically run each time the infected computer boots.

Once it starts the encryption, it uses a combination of AES and RSA ciphers. After encrypting its targeted files, it adds the .cryptotes extension to every affected file. It also drops a file named “readme.txt” containing the following content:

“ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file ROTO Readme file”

If you are one of the unfortunate victims of this crypto-malware, know that paying the ransom won’t guarantee the recovery of your files.
