Juan Francisco BolívarJose Miguel Marichal

Presents a Python tool to proactively identify typosquatted domains pre-configured against Office 365 infrastructure.

Summary

Preemptive Domain Squatting Discovery

0365 Squatting is a Python-based utility created to uncover malicious typosquatted domains targeting organizations before active attacks or phishing campaigns begin.

Querying Office 365 Infrastructure

The tool generates permutation lists of typosquatted domains and queries Office 365 services directly, identifying domains configured in Microsoft infrastructure that may not yet resolve in public DNS.

Defensive Mitigation and Bug Hunting

Identifying configured domains early enables defenders to block malicious mail routes, preempt credential harvesting, and detect potential domain takeover conditions.
