Security researchers at Forcepoint are raising serious alarms about a vulnerability in AI agents that could reshape how we think about trust in these systems. Hidden text embedded on a webpage can quietly plant a false fact into an agent's memory, and that fabricated detail can persist for months, surfacing in completely unrelated tasks weeks later. The attack has already been demonstrated against ChatGPT, Gemini, Claude, and Microsoft three sixty five Copilot, which means this isn't a theoretical concern — it's already in the wild.
Shifting gears, a browser called Iris is turning the fundamental idea of a webpage on its head. Rather than fetching and rendering content that a server prepared in advance, it uses a language model to reconstruct every website from scratch on the fly. The experience is stripped down and sometimes imperfect, but it raises a genuinely interesting question about whether the document web we've known for thirty years is the only way this could have worked.
And over on Hacker News, a small project called Mastgate is quietly earning attention from the Fediverse crowd. It's a relay filter for Mastodon with a clean visual dashboard, giving instance administrators more granular control over what content flows through their servers — a modest but thoughtful tool for a decentralized ecosystem that often struggles with moderation at scale.
