You're tuned in to Tech Beat. Here's what's moving in technology today.

Federal agencies have issued a joint warning that US critical infrastructure is under active attack at an unprecedented scale. Hackers are deploying AI-generated malware against energy, water, and agricultural systems, targeting Siemens programmable logic controllers and disguising their tools as legitimate monitoring software. The attackers' identities remain unknown.

Shifting to a story about what the internet is quietly becoming — a new study finds that roughly a third of all webpages published since ChatGPT's launch show signs of AI authorship. That means a significant and growing share of the web's new content is being written or substantially edited by machines, raising real questions about trust, accuracy, and the long-term texture of online information.

And in a sign that even cutting-edge AI systems have rough days, xAI's Grok has been sending garbled, nonsensical responses to users since at least Wednesday morning. Affected users were running Grok Lite, and the company has yet to offer a full explanation for the breakdown — a reminder that reliability remains one of the harder problems in deploying these systems at scale.

That's your Tech Beat for today. Keep surfing. Tech Beat out.
