FreeLLMFireworks AI breach exposes Notion AI chat transcripts for <1% of workspaces
Hackers accessed billing data and chat logs from Notion users after breaching Fireworks AI's cloud provider.
Fireworks AI confirmed a cyberattack that let attackers breach its cloud provider and access a development system.
The breach gave the hackers billing information and datasets from Fireworks' customers, including Notion.
Notion disclosed that about 1% of its workspaces were affected, with chat transcripts from the Notion AI "Insights" feature stolen.
On November 3, Notion disconnected from Fireworks, deleted stored data, and halted all connectivity and training runs.
The company now provides affected workspace owners with CSV files to review and download the exposed content.
