SITUATION DETECTED: Nearly all of North Korea’s official websites have been offline for over 24 hours, including state media and government portals. No explanation has been given, and the cause is unconfirmed.

SCOOP: Major U.S. banks are detecting unauthorized third-party AI agents inside customer accounts, including some attempting to take actions that appear to be independent of user instructions, sources told Axios. The findings have alarmed banking executives, who are racing to restrict access to their systems as AI moves at a velocity faster than financial institutions can respond, multiple industry and bank executives told Axios. Several banks are now preparing for worst-case and even “day after” scenarios, including how to rapidly secure or restore customer accounts if things go wrong, the people said. Several bank executives told Axios they're struggling to distinguish between human users and AI agents. One executive said banks also struggle to determine whether agents are authorized by customers or potentially operating without their permission, more akin to rogue agent behavior.

Our bot detection benchmark reached the front page of Hacker News (@hackernews) yesterday! 🚀 We tested five leading bot detection systems against modern AI agents, including CloakBrowser, Chromium, Grok, and Perplexity. Proof of Human accurately detected between 95–100% across all five adversaries, with most alternatives specifically struggling against AI-native browsers. We're excited to contribute open research to this problem -- and grateful to the Hacker News community for the discussion!

We’re looking for our next GTM hire to scale and expand how Proof of Human goes to market. You’ll work directly with the founders and staff across sales, growth, and market development: generating pipeline, leading customer conversations, advancing deals, and turning both your intuition, your research, and what you learn on the front lines into sharper positioning, stronger systems, and clearer strategic direction. This is a deeply hands-on role for someone who wants to create the playbook while running it. Sound like you? Apply here: jobs.ashbyhq.com/proofofhuma…

The honor of a lifetime watching @MayankAgrawal & @mdahardy work thru the “trough of sorrow” & come out on the other side w/ @ProofOfHuman. Human verification is becoming fundamental internet infrastructure. 🧱
What began as an effort to build better infrastructure for online surveys and data collection has grown into something larger. Today, we're officially launching Proof of Human on @ycombinator. Our new name reflects our mission: to preserve human trust on the internet in the age of AI. As AI becomes increasingly capable, knowing whether there's a real human on the other side is becoming fundamental infrastructure. If you're working on a difficult human verification problem, we'd love to hear from you. Welcome to the Proof of Human era.

We're excited to officially launch our rebrand to Proof of Human. If you can't tell who's human, the incentive for many online interactions and transactions goes to zero. Proof-of-human technology will therefore become foundational infrastructure as the AI revolution continues. I've spent the last year looking at thousands of human and AI behavioral traces and obsessively improving our models. If human identity is an important part of your product I'd love to talk!

The internet is losing the ability to know who is human. Today, we're launching Proof of Human on @ycombinator. As AI becomes increasingly skilled at solving puzzles, recognizing images, and producing the right answers, knowing whether there's a human on the other side becomes fundamental infrastructure. That’s why we're building Proof of Human: to verify humans continuously, invisibly, and without any interruptions. I'm incredibly proud of what our team has built so far, and grateful to the customers, researchers, and friends who have helped us get here. And we're just getting started. Welcome to the @proofofhuman era.

How successful is Proof of Human at bot detection? A year ago, we evaluated five leading bot detection systems against automated browsers programmed to complete a set of predefined tasks. Since then, browser automation has advanced considerably. Modern AI agents can interpret webpages, plan actions, and interact with interfaces through increasingly capable browser environments. In our latest research, we revisited our bot detection benchmark with stealth browsers and modern AI agents. What did we find? Proof of Human identified 99% of automated sessions, followed by reCAPTCHA v3 at 69.4%, hCaptcha at 44.3%, Cloudflare Turnstile at 42.1%, and Cloudflare Bot Management at 9.1%.

What role do psychologists play in our age of AI? This question was on a lot of students' minds when I visited Yale's Department of Psychology last week. For me, I think the distinction between AI capability and humanness is important to understand as AI models become increasingly capable. It's an intuitive notion for people who studied psychology, but often ignored in traditional AI circles. And, some of the clinical psychology students in the audience were interested in the effects AI chatbots can have on people's mental health. Many people engage with AI for therapeutic help, but how effective are they compared to traditional mental health professionals? How do you think psychology should play a role in AI?

Am I hearing @proofofhuman x @pontifex collab??
In this era of artificial intelligence, it is becoming urgent to distinguish human art from what machines produce. There is an ontological difference, even before an aesthetic one, between art and what a machine can generate through statistical calculation based on millions of images created by others. Algorithms lack the spark of humanity. For this reason, the Church wishes to renew an alliance with artists and cultural institutions to safeguard our humanity.

I am convinced that CAPTCHAs are no longer checking if I am human, they are just using my free labor to train self-driving cars to identify blurry traffic lights.
