- **Behavioral Indicators**: Unauthorized export or collection of extensive employee profile data from an internal proprietary service (MyPBS.org).

- **Recovery actions**: PBS reached out to affected users to inform them of the incident.
## Lessons Learned
- Internal services (like MyPBS.org) hold significant amounts of sensitive employee PII, making them high-value targets even if the primary motive is not immediate financial exploitation.
- The motivation for the leak appeared to be "novelty" or notoriety among peer groups rather than direct financial crime, underscoring that non-financial motivations can still lead to major organizational exposure.
- Exposure of internal data (especially including personal details like hobbies) can lead to severe workplace risk, such as doxxing or harassment, especially for publicly visible organizations.
## Recommendations
- Immediately review and restrict access controls to the MyPBS.org internal service, ensuring Principle of Least Privilege is strictly enforced.
- Audit data collection and export capabilities within all internal employee-facing applications to prevent bulk data harvesting via legitimate pathways.
- Segment employee data storage, ensuring personal information (like hobbies) is separated from core employment records if possible.
- Increase monitoring on outbound data transfers from internal systems, looking for bulk JSON or CSV file creation/transmission.
