Honeyfile

What is a Honeyfile?

A Honeyfile is a decoy file designed to attract and detect unauthorized access or data exfiltration attempts. These files appear to contain valuable or sensitive information but are actually monitored to trigger alerts when accessed, providing early warning of data breaches, insider threats, and unauthorized data access.
