Blue Team — Operational Summary
A file integrity check was performed on the workstation ross-HP-Z230-SFF-Workstation at 2026-05-25 06:58 MDT, resulting in a warning due to detected differences between the AIDE database and the filesystem. The check identified four changes across several system and user configuration files. Specifically, the following files were modified or added: /etc/cron.daily/aide-check (Added), /etc/cron.daily (Changed), /home/ross/.config/dconf/user (Changed), and /home/ross/.config/tiling-assistant/tiledSessionRestore2.json (Changed). The summary indicates that AIDE found discrepancies in the system state, requiring review of the filesystem integrity.

Purple Team — Pattern Analysis
The observed changes involve system cron files and user configuration files, specifically related to scheduled tasks and desktop session restoration settings. The modifications to /etc/cron.daily and the addition of /etc/cron.daily/aide-check suggest potential tampering with scheduled job execution or integrity checking mechanisms. Changes to user configuration files, such as .config/dconf/user and the tiling-assistant session restore file, could indicate adjustments to user environment settings or application configurations. While the changes are localized to system schedule and personal settings, their simultaneous detection via AIDE flags a potential deviation from the established baseline. This pattern does not immediately align with typical background system maintenance or expected background radiation. The critical observation is that an integrity check (AIDE) was triggered and reported a discrepancy, implying that either a scheduled change occurred or the integrity check mechanism itself was modified, warranting a review of the workstation's operational baseline and recent configuration history.
