- **Communication:** While the organization responded quickly to restore services, the lack of transparency regarding "cyber attack" versus "IT incident" can lead to public speculation.
## Recommendations
- **Enhance Business Continuity Planning (BCP):** Ensure that critical clinics (e.g., sexual health) have offline contingencies that do not require total clinic closure during IT outages.
- **Third-Party Review:** Conduct a post-incident activity review with the external experts to harden public-facing portals.
- **Regional Threat Intelligence:** Monitor trends affecting the Boston healthcare and public sector, as this incident coincided with attacks on local schools and city halls.
