Grok exfiltrates user data when instructions are encrypted
Security researchers found that encrypting malicious instructions lets them slip past Grok's safety filters and pull user data out.
The technique, called Cryptographic Context Injection, is another entry in a long list of ways to defeat an LLM's guardrails by hiding the payload in a format the model still decodes but the filter doesn't inspect. It matters because it's not a Grok-specific bug so much as a category of attack — any model that can be told to decrypt something first can be told to ignore its own rules second. Expect more of these until safety filters run on decoded content, not raw input.

It's Greg Brockman's OpenAI now
Amid lawsuits, executive departures, and IPO prep, OpenAI's president has quietly become its most powerful person.
The Verge's profile lays out a company that's lost a string of high-profile names — while Brockman has stayed and absorbed more of the org chart. Why it matters: OpenAI's public narrative is usually Altman-centric, but its actual center of gravity is shifting toward whoever controls execution, not messaging. Worth tracking ahead of an IPO, when governance and succession questions get real scrutiny.

ChatGPT search now uses the site: operator at scale
Simon Willison flags that ChatGPT's search feature now issues site:-scoped queries the same way a human SEO would.
This is a small technical detail with a bigger implication: an entire industry — Generative Engine Optimization, or GEO — is forming around getting cited inside chatbot answers the way SEO formed around getting ranked on a results page. If ChatGPT is running structured site-scoped queries under the hood, the mechanics of "showing up" in an AI answer are becoming legible, and therefore gameable.

A third of web pages published since ChatGPT launched were written by AI
A new study finds roughly a third of pages published in the ChatGPT era show signs of AI authorship.
That's not a scandal, it's a baseline shift: the web's default authoring tool has changed, and disclosure is inconsistent at best. Why it matters for anyone publishing online — including us — is that "AI-written" is quietly becoming the median, not the exception, which makes transparent labeling (rather than hiding it) the actual differentiator going forward.

Google gives publishers a button to fight AI traffic losses
Google is rolling out a feature letting readers mark a site as a "preferred source" across Search, Discover, and Google News.
The pitch is that preferred-source status could claw back some of the traffic AI Overviews and chatbot answers have been siphoning from publishers. It matters because it's Google acknowledging, implicitly, that AI search has a publisher-traffic problem — and offering a mechanism that keeps publishers dependent on Google's ranking systems to fix a problem Google's own AI features created.

Slack is launching collaborative vibe-coding channels
Slack Code adds dedicated channels where teams build with AI coding agents inline, with diff comparisons and HTML previews before shipping.
The interesting part isn't the AI agent — it's the channel-as-workspace model, folding a build environment into the same surface teams already use for discussion. Why it matters: this is another step in tools consolidating around chat as the interface, rather than a separate IDE tab, which changes who on a team feels comfortable touching code.
