Cyberattack on Fireworks AI exposed Notion customers' AI chat transcripts

Fireworks AI confirmed a cyberattack in which an attacker breached its cloud provider to reach a Fireworks development system, exposing some customer billing information and datasets. Notion said the incident affected about 1% of its customers and that hackers took chat transcripts from Notion AI users of its Insights feature; it disconnected from Fireworks on November 3. Fireworks believes the attackers were financially motivated and aimed to sell access to large language models, and this is its second breach in as many months after an October incident.
