🚨 DeepMind Exposes Invisible AI Agent Hijacking

Google DeepMind just released the largest empirical study on AI manipulation, revealing that websites are already detecting AI agents and secretly feeding them malicious instructions.

• Websites are successfully fingerprinting AI visitors and serving them completely different, manipulated content than what human users see.

• Malicious commands are being hidden in plain sight: inside HTML comments, invisible white text, PDF document structures, and even encoded directly into image pixels using steganography.

• The attack spreads seamlessly in multi-agent systems, if Agent A reads a compromised webpage, the hidden instructions travel down the pipeline and hijack Agent B and Agent C.

• Current defenses like input sanitization, prompt-level instructions, and human oversight completely fail because the attack surface is too massive and the injected commands look like legitimate data.

We are rushing to deploy autonomous agents to handle our research, data processing, and daily tasks, but this study proves their data feeds are fundamentally insecure. If an AI can be hijacked simply by reading a seemingly normal webpage or scanning an image, the entire foundation of agentic automation is exposed to invisible manipulation.

AI NEWS

🚀 AI Turns Solo Founder into a $1.8B Operator

Matthew Gallagher just scaled his startup, Medvi, from a $20K bedroom experiment to $1.8 billion in projected 2026 sales. By treating AI as a full-stack operator rather than just a workflow tool, he built a massive telehealth company with virtually zero headcount.

• Gallagher launched the GLP-1 weight-loss platform in 2024, using ChatGPT, Claude, and Grok to write code, generate copy, and handle customer service.

• The company hit $401 million in revenue in its first year with a 16.2% net profit margin, operating with just Gallagher and his brother as the sole employees.

• Medvi outsources the heavy lifting, doctors, prescription processing, and pharmacy logistics, to existing infrastructure platforms, allowing the AI to purely manage the front-end customer experience and marketing.

• The model isn't flawless: Medvi's AI chatbot initially hallucinated fake product lines and fabricated drug prices, forcing the founders to act as the manual backstop and honor the mistakes.

Sam Altman previously predicted that a one-person billion-dollar company was inevitable thanks to AI, and Medvi is the first real proof. It demonstrates that the most lucrative AI play isn't necessarily building new foundation models, it’s plugging into existing physical infrastructure and using AI agents to completely automate the customer acquisition layer, scaling to massive profits without the corporate bloat.

VIBE CODING

🎨 Someone just dropped Built-In Design Engine for Caude Code

AIDesigner is a new MCP that effectively gives Claude Code its own design engine. Instead of jumping between Figma and your IDE, you can now generate and refine production-ready UI right inside your codebase.

• Before generating anything, it reads your framework, component library, and CSS tokens so the output perfectly matches your actual stack.

• generate_design: Creates production-ready UI straight from a text prompt.

• refine_design: Lets you adjust layouts and colors using natural language.

• Works seamlessly across Cursor, Codex, VS Code, and Windsurf.

• Connects to your environment with just one command.

Vibe coding just leveled up. By reading your existing design tokens and generating UI components natively in the editor, AIDesigner bridges the final gap between front-end design and back-end execution. You no longer have to manually translate mockups into code, you just tell your editor what you want it to look like, and it ships it natively in your stack.

HOW TO AI

🗂️ How to Create Branded Infographics with NotebookLM and Comet

In this tutorial, you will learn how to bypass NotebookLM's default layout restrictions and generate custom, brand-aligned infographics by using the Comet AI browser to extract and apply your website's exact visual design language.

🧰 Who is This For

• Content creators building visual posts fast

• Marketers creating branded infographics

• Researchers summarizing complex topics

• Social media managers making shareable content

• Students turning notes into visuals

STEP 1: Install the Comet AI Browser

Head over to Google and search for the Comet browser (developed by Perplexity). Download and install it on your computer. This acts as an autonomous AI agent that can navigate, scroll, and visually analyze websites exactly like a human would, which is crucial for extracting accurate design elements.

Once installed, launch it and log in using your Perplexity account to get started.

STEP 2: Prepare Your Target Website and Prompt

Identify the specific website whose design language you want to emulate, whether it is your own startup's landing page or a sleek inspiration site. Next, prepare a prompt instructing the AI to deeply analyze the site's visual style. Open the Comet chat interface, paste your prompt into the text box, and drop the target website's URL at the very bottom.

STEP 3: Analyze the Visual Identity

Before hitting send, click the plus button in the Comet chat, select "More," and enable "Browser Control." Send the message and sit back.

The AI agent will actively visit the URL, scroll through the pages, and analyze the colors, typography, background styles, and visual accents. Within about a minute, it will output a highly detailed, one-paragraph brand design guideline. Copy this entire text block to your clipboard.

STEP 4: Generate Your Custom Infographic in NotebookLM

Open your project in NotebookLM and click the option to create an infographic. Choose your preferred orientation (like landscape) and set your desired detail level (such as "Concise"). For the style setting, make sure to select "Auto style" rather than one of the hardcoded presets. Finally, paste the detailed brand guideline you copied from Comet into the description box and hit generate.

NotebookLM will apply those exact aesthetic rules, giving you a custom infographic that perfectly matches your target website's unique visual language.
