uSjBVNE = "%Application Data%\sevnz.exe which we need to block in VSE policy.I just wanted to know what is the best possible rule we can create for blocking the registry as mentioned in the link to avoid the impact of Scarab Ransomware.
It has rules for different ransomware types, which includes application protection rules for blocking certain registry or file/folder creation/executions.
Whilst the link you gave indicates a specific executable name, its worth considering that there are likely to be versions of this that generate the executable with a random name, rather than one specific. This will be something to consider when you create you rules.
If you want specific details for what rules to create for Scarab, I think your best bet would be to log a request with Support.
