## In brief

- Attackers accessed chat transcripts for fewer than 1% of Notion workspaces, according to SecurityWeek.
- The breach was tied to a hack of Fireworks AI.
- Most of the accessed transcripts could not be attributed to specific users.

## Why it matters

Teams whose Notion workspaces used the chat features may have had conversation content exposed, so they should assess what sensitive information was discussed there.
