What information security risk could be identified with the use of the DPAT tool?

Identifying admin-to-user password reuse requires comparing hashes between separate account objects across privilege tiers, which is a different analytical function not central to DPAT's design.

DPAT correlates password hashes extracted from Active Directory with authentication event data to identify accounts whose credentials are used from multiple distinct workstations, which directly indicates credential sharing among users. When multiple individuals share a single account, the same hash appears across logon events originating from different machine names, a pattern DPAT surfaces during its audit. This makes it an effective tool for detecting shared account abuse in enterprise environments.

Remote connections from personal workstations to servers are a network access control and VPN policy issue, not detectable through password hash analysis.

Detecting password incrementing patterns requires cracking plaintext passwords and comparing them across multiple historical snapshots over time, which is outside DPAT's scope.
