What appears to be another variant of a notorious STOP ransomware strain was recently detected under the file extension it adds to the files, encrypted by it. The ransomware may use the _open_.txt ransom note that contains the extortionist message of the cyber-criminals who are behind it. In the note, they usually ask for a ransom to be paid in BitCoin in order for your files to work again.

After the files are dropped, STOP .gropas ransomware could begin to modify your computer, starting with creating registry entries in the following Windows sub-keys:

→HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization
HKEY_CURRENT_USER\Control Panel\Desktop\ScreenSaveTimeOut
HKEY_CURRENT_USER\Control Panel\Desktop
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Furthermore, the .gropas variant of STOP Ransomware could begin to delete backed up files and other important files, saved on your computer. This can happen if the virus runs the vssadmin and several other commands that disable Windows Recovery services and delete the shadow copies of your PC.

To encrypt files, the .gropas variant of STOP ransomware may scan in all of your Windows folders, besides the ones that are system directories. In the targeted folders, all images, videos, documents and other types of files become AES encoded with the added .gropas extension:

After encryption is complete, the STOP ransomware virus generates several unique types of keys which are usually used by the crooks after you pay the ransom to unlock your files. Paying the ransom to the criminals behind .gropas ransomware is strongly inadvisable, no matter how convincing they might be. For one, you cannot trust them that they won’t continue extorting you and also you cannot keep supporting their cyber-criminal operation by funding them.
