YHK - yet another hacker news clone

This is a strong reminder that a company's security is only as strong as its third-party integrations. Even when customer data is handled by trusted platforms, external AI vendors can introduce additional risks. Businesses need to carefully evaluate vendor security, limit the data shared with external services, and maintain transparency when incidents happen. As AI adoption grows, third-party risk management should become a core part of every company's security strategy.

Forcing us to the Enterprise plan to see which members are affected huh? Classy move Notion.

So Fireworks is ZDR by default, yet Notion configured (asked) Fireworks to retain data? Otherwise, how is there anything to leak?

On the main fireworks breach page, they also say some customer weights of models and datasets to train them were leaked.

the whole incident response post feels like a huge cop-out. “abundance of caution”, the vendor is one of the biggest, so ofc it’s not our fault for choosing them… etc.

Does this reflect on Fireworks’ culture?

> Upon analysis of the new data, we discovered that it included unattributable Notion AI chat transcripts used for the Insights feature. Chats weren't labeled with who wrote them or which workspace they came from, and the transcripts did not contain any tool call results. Beyond the words in the chat transcripts themselves, the data contained no information that could specifically identify the workspace, user, or company.

> As a precaution, we recommend that you treat this unattributable data as if it were exposed. If anyone on your team pasted sensitive information like passwords, API keys, or other credentials into Notion AI during this timeframe, we recommend rotating them right away.

Okay, so the actual impact is quite interesting: they did not notify you if they could not attribute the transcripts to you! You should really treat anything sensitive sent to Notion AI as compromised because they are not sure where these transcripts came from.

Does anyone actually use the AI features? $job switched off because they spent too much time on AI features we never used, and too little time making a text editor that wasn't painful to use

> “Unattributable” means the chats weren't labeled with who wrote them or which workspace they came from, and the transcripts did not contain tool call results. Beyond what’s in the chat transcript itself, there’s no information tying the chat back to a workspace, user, or company.

This is astonishing.

They’re saying “OTHER THAN THE ACTUAL CONTENTS OF YOUR CONVERSATION, NO INFORMATION WAS PRESENT”. That is not what unattributable really means and they’re trying to assert otherwise.

It’s trivial to identify the organisation or individuals involved in a conversation most of the time, but Notion are trying to make out that because the metadata wasn’t present, it’s no cause for concern.

That’s absolute bullshit and will give people a false sense of security. The contents of your conversation IS the critical information. Notion’s desktop app is very aggressive in prompting users to transcribe their calls and I imagine a large proportion do so by default. The potential for harm here is large.

I appreciate it’s Fireworks’ fault this happened, but Notion’s response destroys my confidence in them.

If you’re looking for a Notion alternative you can self-host, I’m building Docmost. We launched on HN 2 years ago.

On Openrouter the Fireworks AI is labeled as ZDR.

> Private: this provider does not train on prompts and does not retain prompt data.

So how come notion discovered that they actually stored the data?

I used Notion as a form of social CRM and it really helped me out with that task. Now, all their contacts are out. Nice stuff Notion.
