Sub-technique of: T1087
Adversaries may attempt to get a listing of email addresses and accounts. Adversaries may try to dump Exchange address lists such as global address lists (GALs).
In on-premises Exchange and Exchange Online, the Get-GlobalAddressList PowerShell cmdlet can be used to obtain email addresses and accounts from a domain using an authenticated session.
In Google Workspace, the GAL is shared with Microsoft Outlook users through the Google Workspace Sync for Microsoft Outlook (GWSMO) service. Additionally, the Google Workspace Directory allows for users to get a listing of other users within the organization.
Platforms: Windows, Office Suite
Identify Attack Surface: Determine if the target environment is susceptible to Email Account by examining the target platforms (Windows, Office Suite).
