The Able Ransomware In Detail
Similar to the Italian Bloccato Ransomware it has been executed on the computer, the Brazilian crypto malware may situate various files in the following Windows locations:
After this has been done, the malware may execute its malicious modules, and they may have different functions. One of the functions may be to modify the following Windows Registry Entries:
This may be done by the Brazilian ransomware to make its malicious file that encrypts the data on the compromised device to run automatically, usually when you restart your computer. Once this file runs, it may begin to scan for and encrypt files with different file extensions, such as the following examples:
→ “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.

After encrypting the files of the compromised computer, the ransomware adds the .lock file extension to the encrypted files of the compromised computer, for example:
After the files have been encrypted, the virus drops a “MESAGEM.txt” file on the desktop or on the folders with encrypted files. It contains the following ransom note:
TODOS OS SEUS ARQUIVOS FORAM BLOQUEADOS !
PARA DESBLOQUEAR SUAS INFORMAÇÕES, ACESSE O LINK: http://is.gd/comunicado1
ALL YOUR FILES WERE LOCKED!
TO UNLOCK YOUR INFORMATION, VISIT THE LINK: http://is.gd/comunicado1
Not only this, but the .lock malware also sets the following message as a wallpaper on the infected computer:
The message from the wallpaper roughly translates to the following:
→ “All your files were locked !!!
So the decryption is the same, go to the ‘message’ file created on your desktop, after accessing instructions follow them for the release of all your files!
If you do not follow the steps, your entire database will be deleted !!!
Without following the message instructions and impossible the recovery of files !!!!”
