What happened
Between July 8 and July 12, 2025, an unauthorized actor accessed HCIactive's computer network and copied files containing sensitive personal and health information.

What broke inside the model
- 01 · TriggerA request triggers retrieval or context loading.
- 02 · Model stepThe context pulls in another user's content.
- 03 · Control gapNo boundary enforces isolation at the moment of output.
- 04 · FailurePrivate data crosses into the response.
- 05 · ConsequenceOne user sees another's data, and disclosure follows.
One user's content crosses the retrieval boundary into another's response.
The failure was a breach of network security and access controls that permitted an external actor to exfiltrate files from the company's internal systems. While HCIactive provides AI-powered software, the mechanism of failure was a general infrastructure security breach rather than a failure within an AI model's logic or output.

Realm can detect when a response is about to emit data that falls outside the bounds of the current user and context, and block or redact it inline, at the moment of generation rather than after the data has left.
