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

Pico ransomware is a data-encrypting virus created to lock files and demand ransom from victims. Creators of Pico ransomware asks its victims to pay $100 either in Bitcoin or Ethereum. Based on the analysis done by security experts, Pico ransom has taken the source code of Thanatos ransomware.
The instant it infects a computer, it creates the following folders and file in the Desktop:
%Desktop%\Ransomware\ThanatosSource\Release\Ransomware.pdb
After dropping its malicious components, Pico ransomware starts to implement its attack by modifying registry keys and sub-keys in the Windows Registry so that it can run its malicious components namely “Microsoft Update System Web-Helper” and “README.txt” automatically on every system boot. It may also collect information about the user and the system and use them for its attack. After that, it scans the computer in search for files with the following extensions:
.PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

Once it finds the files with the extensions listed above, Pico ransomware will encrypt them and add the .PICO extension to each one of the encrypted files. Following the encryption, it opens a file named README.txt” which contains the ransom note stating:
