Project: Passive Reconnaissance Assessment
Author: Gabriel S Passos
Date: 2026-03-25
Target: gabrielpassos.com
This report was generated exclusively using passive reconnaissance techniques. No direct interaction, scanning, probing, or traffic was sent to the target infrastructure. All information was obtained from publicly available sources.
This document presents the results of a passive reconnaissance assessment, aiming to identify publicly exposed information related to the target that could contribute to its external attack surface.
This section is intended for management and non-technical stakeholders.
The assessment relied solely on: - Public registration databases - Certificate transparency logs - Passive DNS datasets - Search engine indexing - Public code repositories - Archived web data
