Hi 

Can i build a spam/phishing alert using o365 audit exchange logs ? 

 

Hi @rahul7514 ,

https://learn.microsoft.com/en-us/purview/alert-policies

Yes you can. The M365 Activity logs will generate a specific event with the operation `AlertTriggered`for any of the above policies.

The default parser should be mapping this to metadata.product_event_type = "AlertTriggered"

There are a few phishing ones included, just need to make sure they are enabled in your purview console and you have the correct licensing.

Here is sample sanitized payload

 

{ "CreationTime": "2024-12-05T00:08:34", "Id": "string", "Operation": "AlertTriggered", "OrganizationId": "string", "RecordType": 40, "ResultStatus": "Succeeded", "UserKey": "SecurityComplianceAlerts", "UserType": 4, "Version": 1, "Workload": "SecurityComplianceCenter", "ObjectId": "string", "UserId": "SecurityComplianceAlerts", "AlertId": "string", "AlertLinks": [ { "AlertLinkHref": "" } ], "AlertType": "System", "Category": "ThreatManagement", "Comments": "New alert", "Data": "{\\"ts\\":\\"2024-12-05T00:07:53.0000000Z\\",\\"te\\":\\"2024-12-05T00:07:53.0000000Z\\",\\"tid\\":\\"string\\",\\"tdc\\":\\"1\\",\\"af\\":\\"0\\",\\"tht\\":\\"Phish, Malicious\\",\\"dtech\\":\\"MLModel\\",\\"als\\":\\"Protection\\",\\"op\\":\\"Protection\\",\\"wsrt\\":\\"0001-01-01T00:00:00\\",\\"mdt\\":\\"u\\",\\"rid\\":\\"x\\",\\"cid\\":\\"x\\",\\"ad\\":\\"This alert fires when message containing phish was delivered due to an ETR override. -V1.0.0.5\\",\\"lon\\":\\"Protection\\",\\"an\\":\\"Phish delivered due to an ETR override\\",\\"sev\\":\\"Informational\\"}", "Name": "Phish delivered due to an ETR override", "PolicyId": "x", "Severity": "Informational", "Source": "Office 365 Security & Compliance", "Status": "Active" }`
