What is Colecyrus@mail.com ransomware? And how does it carry out its attack?

Colecyrus@mail.com ransomware is a new file-encrypting Trojan infection that corrupts important data stored on the infected computer and then demands a ransom from its victims. Colecyrus@mail.com ransomware’s first attack was observed on October 25, 2017. It behaves just like a typical ransomware infection – once this ransomware’s malicious payload is running in the computer, it initiates a sequence of malicious tasks to start its attack. One of the first things it does is to connect to its Command and Control server to send information about the infected system and download additional malicious components. Aside from that, Colecyrus@mail.com ransomware also creates new files in some of the important Windows system folders and proceeds to activate its malicious processes. It then starts to look for files to target, especially the ones who are generated by the user. According to researchers, it encrypts the files with the following formats:

.aif, .apk, .arj, .asp, .bat, .bin, .cab, .cda, .cer, .cfg, .cfm, .cpl, .css, .csv, .cur, .dat, .deb, .dmg, .dmp, .doc, .docx, .drv, .gif, .htm, .html, .icns, .iso, .jar, .jpeg, .jpg, .jsp, .log, .mid, .mp3, .mp4, .mpa, .odp, .ods, .odt, .ogg,.part, .pdf, .php, .kg, .png, .ppt, .pptx, .psd, .rar, .rpm, .rss, .rtf, .sql, .svg, .tar.gz, .tex, .tif, .tiff, .toast, .txt, .vcd, .wav, .wks, .wma, .wpd, .wpl, .wps, .wsf, .xlr, .xls, .xlsx, .zip.

On the encryption process, Colecyrus@mail.com ransomware utilizes the AES 256 cipher to leave the files unreadable along with adding the extension .colecyrus@mail.comb007 on the each one of them. The ransomware delivers the decryption key to its Command and Control server and creates a text file named Readme.txt in the desktop which reads as follows:
