hawk: gathering information related to O365 intrusions and potential Breaches
What Hawk is and isn’t
Hawk provides a Limited analysis of the gathered data. This is by design! Hawk is here to help get all of the data in a single place it is not designed to make any significant conclusions about this data. This is intentional since it is impossible for the tool to know enough about your environment or what you are concerned about to make a legitimate analysis of the data.
Hawk’s goal is to quickly get you the data that is needed to come to a conclusion; not to make the conclusion for you. We’ve structured the exported data in a manner of which can help analysts quickly triage known malicious Indicators Of Compromise (IOC) but again is NOT an all exhaustive list.
Powershell Based tool for gathering information related to O365 intrusions and potential Breaches
The Hawk module has been designed to ease the burden on O365 administrators who are performing a forensic analysis in their organization.
It does NOT take the place of a human reviewing the data generated and is simply here to make data gathering easier.
HOW TO USE:
Hawk is divided into two primary forms of cmdlets; user based Cmdlets and tenant based cmdlets.
User-based cmdlets take the form Verb-HawkUser. They all expect a -user switch and will retrieve information specific to the user that is specified. Tenant based cmdlets take the form Verb-HawkTenant. They don’t need any switches and will return information about the whole tenant.
A good starting place is the Start-HawkTenantInvestigation which will run all the tenant based cmdlets and provide a collection of data to start with. Once this data has been reviewed if there are specific user(s) that more information should be gathered on Start-HawkUserInvestigation will gather all the User-specific information for a single user.
All Hawk cmdlets include help that provides an overview of the data they gather and a listing of all possible output files. Run Get-Help -full to see the full help output for a given Hawk cmdlet.
Some of the Hawk cmdlets will flag results that should be further reviewed. These will appear in _Investigate files. These are NOT indicative of unwanted activity but are simply things that should be reviewed.
