'This hunting query identifies GitHub activites its the first time a user deleted a repo that may be a sign of compromise.'
'This alerts when the account setting is changed to allow either external domain access or anonymous access to meetings.'
'This detection highlights executables deployed to hosts via either the Default Domain or Default Domain Controller Policies. These policies apply to all hosts or Domain Controllers and best practice is that these policies should not be used for deployment of files.
A threat actor may use these policies to deploy files or scripts to all hosts in a domain.
This query uses the ASIM parsers and will need them deployed before usage - https://docs.microsoft.com/azure/sentinel/normalization'

'This hunting query looks for file paths/hashes related to observed activity by Dev-0228. The actor is known to use custom version of popular tool like PsExec, Procdump etc. to carry its activity.
The risk score associated with each result is based on a number of factors, hosts with higher risk events should be investigated first.
