MailSniper — Attack Tool
MailSniper is a penetration testing tool for searching through email in a Microsoft Exchange environment for specific terms (passwords, insider intel, network architecture information, etc.). It can be used by a non-administrative user to search their own email, or by an Exchange administrator to search the mailboxes of every user in a domain.
Tool identity and evidence

Technique-specific simulations and detections
Detection links describe the associated behavior, not independently verified tool-specific signatures.
Telemetry context
Derived from the explicitly linked TTPs; not proof of sensor coverage for this tool.
Pinned research references. No browser attack runner or production-validated detector is asserted. Imported procedures remain unvalidated; any bounded lab evidence has its own scope. ATT&CK / Atomic provenance · Detection provenance.
