The knowledge management application Notion has released an announcement acknowledging that some users' AI chat records have been leaked. The company stated that the affected workspaces account for less than 1% of all workspaces and is currently notifying the affected users. If users have provided their account, password, or credentials to the AI, Notion recommends treating them as compromised, immediately checking the login records of the relevant accounts, and changing passwords or credentials.The source of this incident is a hacker attack on the service provider Fireworks. Notion uses Fireworks AI to process data for a feature called Insights, which helps workspace administrators understand how team members are using AI. To generate this analytical data, Notion sends the saved AI conversation content to Fireworks for processing. Fireworks has also served as the inference service provider for some open-weight models in Notion's products.Notion stated that the potentially leaked data mainly consists of user chat records, including the chat content input by users and the replies given by the AI. The announcement explained that some users may have sent their account, password, or various credentials to the model while using AI. Notion advises the relevant users to immediately change these passwords or credentials and check for any unusual activity in their account login records.

Brian Hong announced that he has joined the social trading application fomo, responsible for the Asia-Pacific region. Brian Hong previously publicly identified as the head of growth for consumer blockchain Abstract in the Asia-Pacific region. He stated that many high-quality trading ideas around the world have never left the language in which they were originally written; traders in Seoul and New York can focus on the same asset for months but do not have access to each other's work. Both parties see the same prices, but the ideas behind the trades remain trapped in circles separated by language, local communities, and existing information flows.He wrote that for nearly a decade, he has been connecting products, services, and information between the East and West. Products are now easier to cross borders, but ideas are not; he feels this most acutely in the market, where some ideas with significant upside potential remain confined to a single language and community. He stated that fomo is the first product that makes him feel this situation can change, as it does not require consideration of chains or cross-chain bridges; it faces a single market where information flow shows what people are actually buying. A trade does not need translation; ideas from Seoul can reach New York on their own, with attribution remaining with the originator.Brian Hong expressed that this feeling has not faded, and he agrees with fomo's direction and development team, and will help grow a product he already uses daily. He referred to the Asia-Pacific as the most important region for this matter, but the Asia-Pacific is not a single location; the languages, cultures, and platforms differ. Most of what happens here exists in communities that are not visible to the outside world. Introducing users is only part of the work; a larger part is putting ideas that the world has yet to see onto the same map. He has opened private messages to traders, large players, creators, and chain builders in the region.
