The tractor people?"},{"host":"Eric","text":"John Deere, SharkNinja, Cummins — all hit by one guy, using open-source AI agents on something called Cairn."},{"host":"Sloane","text":"And the companies say the impact was limited. So what exactly did he get into?"},{"host":"Eric","text":"He breached their sites, poked around. No massive data dump, no ransom. But that's not the point."},{"host":"Sloane","text":"The point is the demo reel, right? One man, a few thousand dollars, and a hundred companies."},{"host":"Eric","text":"Exactly! This used to take a team of hackers, months of work. Now you rent compute, spin up agents, and let them loose."},{"host":"Sloane","text":"So either they're downplaying it, or this was just a proof of concept that didn't do real damage."},{"host":"Eric","text":"Proof of concept? Sloane, if one guy can get inside a hundred corporate networks, that's not a concept. That's a broken lock on every door."},{"host":"Sloane","text":"But they didn't steal anything, they didn't shut anything down. It's like someone walked into an unlocked office, looked around, and left."},{"host":"Eric","text":"And now we know those offices are unlocked. You think the next guy won't take the files? Come on."},{"host":"Sloane","text":"The next guy might. But the companies say limited impact, so let's not turn a security test into Armageddon."},{"host":"Eric","text":"Armageddon? No. But it's a clear signal: AI agents are now a real tool for attackers, not just a lab experiment."},{"host":"Sloane","text":"And you think this is a turning point? Because I've seen a hundred breathless posts about AI agents, and most of them are just chatbots with extra steps."},{"host":"Eric","text":"This one actually breached live systems. That's not a chatbot. That's an autonomous intruder."},{"host":"Eric","text":"Which is scarier! No barrier to entry. Five thousand dollars in compute, and you're inside John Deere."},{"host":"Sloane","text":"I'll give you that: the cost is shockingly low. But if the impact was truly limited, maybe the agents aren't as capable as the headline suggests."},{"host":"Eric","text":"They're capable enough to find vulnerabilities across a hundred different sites. That's not nothing."},{"host":"Sloane","text":"Fine. It's a warning shot. But I'm not ready to call it a weapon until someone actually pulls the trigger."},{"host":"Eric","text":"The trigger's already pulled, Sloane. The question is who was standing behind the target."},{"host":"Sloane","text":"The post also says Google Trends shows AI agents up 62 percent in the last year. So everyone's paying attention now."},{"host":"Eric","text":"For good reason. This is being called the first real-world demo where AI did the hacking, not a human guiding every step."},{"host":"Sloane","text":"We'll see. Next time a breach happens, I want to know if the AI actually stole something or just rang the doorbell."},{"host":"Eric","text":"We'll probably find out sooner than we'd like."}]}
