Gah - What a dumb take. There's nothing APT about an agent that you can open on a webpage to do things. If anything it's a fantastic accessibility win. Some people's critical thinking turns off when it comes to AI flows.

Fine. Now give me back browser plugins that can actually do whatever I want them to.

You can justify manifest v3 for security reasons, or you can can do this. You cannot do both without severe cognitive dissonance.

Like that stopped anyone before from just ignoring the "cognitive dissonance" and moving ahead anyways with whatever gives shareholders the most short-term profits...

You can "hack" the agent by literally just putting some text on any website it reads. AI browsers have turned EVERY comment feature EVERYWHERE into XSS.

This is stupid but mostly benign where the AI only spits out text. It's catastrophic if the AI does anything to the webpage. (And AI firms want people to use this everywhere)

What is the future of this product supposed to be? I send a 1 dollar cent transaction to someone, with a prompt injection in the description, and their AI agent gleefully sends me a thousand bucks in return?

1) This is not APT.

2) While injection has potential, this is fairly well mitigated. Look at comet and others.

These are all whataboutisms coming from a place of fear.

Pretty sure simonw's lethal trifecta [1] has not been "fairly well" mitigated.

Good thing we're not talking about a LLM then.

From the article: It's a side page agent that has only access to the page, and outputs content in text only, and awaits user confirmation on actions. It's all on the page. It's I guess it's a mono-fecta?

Then it's contained but depending on the user it can be a vector for a (para)-social engineering attack.

PS: It is Gemini based, that's an LLM.

No LLM model has enough mitigations to prevent injections.
