OSINT

Tenant information

This Open-source Intelligence (OSINT) tool will extract openly available information for the given tenant. The tool is using APIs mentioned in my previous blog post and in MS Graph API documentation.

Domain details is returned only for the 20 first domains. For complete recon information, please use AADInternals PowerShell module.

Note: CBA status is valid ONLY if email of an existing user is given. Using tenant id, domain name, or email of non-existing user may show false negatives.
Note: For tenants with many domains, it may take up to 30 seconds to complete.

Enter tenant id, domain name, or email:
