This rule detects activity from a list of specified malicious IP addresses across network connection events and sign-in attempts. It correlates `DeviceNetworkEvents` (network connections from devices) and `SigninLogs` (user authentication attempts) to identify instances where these IPs are involved. The rule is designed for hunting, looking back 30 days for any activity originating from the defined IP addresses.

'Any Alerts that fired related to a given IpAddress during the range of +6h and -3d'
This query uncovers seen IPAddressV4 network subnets
This query is a function that consumes the publicly available Azure IP address list and checks a list of remote IP addresses against it to see if they are Azure IP addresses or not.
To use this, replace the demo portion of the query (DeviceNetworkEvents | take 10000) with your query with the column name of the IP address to check named RemoteIP. The function will add a new column to the end called IsAzure denoting if the IP address range is in the published list or not.
Please note that over time the URL to the Azure IP address list may need to be updated.

Determines DeviceId from internal IP address and outputs all alerts in events table associated to the DeviceId.
Example use case is Firewall determines Internal IP with suspicious network activity. Query WDATP based on date/time and Internal IP and see associated alerts for the endpoint.
