> Two quick notes first. The impact I describe is hypothetical. It’s what an attacker could have done with this access, but luckily I found the bug instead, reported it, and never touched any customer data or PII.

I am the last person to judge someone for using AI to help them write a blog post, but what I wonder is: Do people not read what the AI produces before putting their name on it, or is the AI writing style not obvious to some people, or do they just not care that it's obviously AI and bad style?

What is Antares? Can't find anything related to it except for the 1B model, which does not seem to be capable of autoresearch.

UPD: It's his personal bot.

It's a little perplexing. Of course it's always a controversial topic since it's difficult to value an exploit, but whenever we read about these online, which probably goes through some survivorship bias, they seem pretty low.

On https://www.microsoft.com/en-us/msrc/bounty it seems the top is $100,000 or $250,000 depending which program this counts under.

What does HN think? Why would it be only $5000?

Next time you find a bug like that, offer it to the black market, you could make millions instead of measly salty peanuts

You’re going places kid :) keep up the good work

wow I am so surprised to hear once again how JWTs are terrible

Wait until someone does that to your favourite cloud provider's customer data.

>Microsoft had editorial control over this post, cutting sections and figures and reshaping how the impact is described before publication.

that is... not great. shame on microsoft.

There is an internal library at Microsoft that reliably avoids all these JWT problems - Microsoft Identity Service Essentials (MISE). Adopting MISE and upgrading to the latest versions of it have been part of the Secure Future Initiative (SFI) that can be read about in the news of previous years. Unfortunately it sounds like the service team intentionally deferred the compliance alerts they will have received.

Damn, these guys got schooled by a 15 year old! Say less...
