In a small classroom in western China, children once learned to sing and count in the language of their ancestors — Uyghur. Then the doors were locked, and founder Abduweli Ayup went from teacher to enemy of the state. We return to the first episode in our series, ERASED.

ERASED is a four-part investigation into how China is wiping Uyghur culture from existence — one law, one app, one person, one website at a time. From shuttered schools to vanishing websites, ERASED uncovers an authoritarian regime’s campaign to delete a culture — and the unlikely rebels racing to stop it.

Zoom was built for speed. But in its rush to connect us, it may have left a few doors open. We return to a conversation with Dan Guido, the CEO of the cybersecurity firm Trail of Bits. He walks us through how one of Zoom's most mundane features became a hacker's best friend — and why the weakest link in crypto isn't the blockchain … it's the person who thinks they're too smart to get scammed.

An episode from kill switch:

On October 20, an Amazon Web Services outage knocked out big swaths of the internet — from Snapchat and Reddit to smart beds and government services. On the series kill switch, host Dexter Thomas talks with Dr. Corinne Cath, a cultural anthropologist and tech researcher, about how three companies — Amazon, Microsoft, and Google — came to dominate the cloud, why that’s risky for democracy, and what we can do about it.

We return to a conversation we had with Dr. Stephen Xenakis, a psychiatrist and retired Army brigadier general. He's has always had an open mind when it comes to cutting-edge technology. Now he’s looking at AI to see if it can help doctors treat veterans struggling with mental health.

An episode from The Homework Machine:

Three years after ChatGPT landed in classrooms, schools are still sorting out what comes next. What counts as cheating when AI can do your homework? How should teachers use it, or not? And how do students feel about learning alongside a machine? The Homework Machine explores the promises and pitfalls of AI in education through the people living it – teachers, students, and the communities caught in-between. 

For years, North Korea has quietly dispatched an army of IT workers overseas—not to innovate, but to infiltrate. Disguised as freelancers, they apply for jobs, breach systems, and wire stolen funds back to Pyongyang. We return to a rare conversation with one of them—a defector—about the regime’s digital underworld, and the personal toll of escaping it.

We return to a story on the Akira ransomware group. For 150 years Knights of Old, a U.K. logistics company, survived everything from two world wars to Brexit. Then Akira stormed the company's networks. In just a blink of an eye, everything changed.

Washington is trimming budgets… and bleeding digital expertise. So what happens when national security is run by agencies living in the past? Sue Gordon, former Principal Deputy Director of National Intelligence, helps us break it down.

We tend to picture cyberattacks as distant battles—state hackers, big targets, glowing maps of global chaos. But often, the frontlines are more local: a water plant, a 911 system, the power lines outside your window. In this CyberMonday crossover with WAMU’s 1A, we examine a small-town breach, the fragility of our digital infrastructure—and what it means for all of us.

Milo Comerford has been studying online extremism for more than a decade. He’s watched ideologies rise and fall, platforms shift, and tactics mutate. Now, as kids fall into violent online communities with no ideology at all, Milo says we’re overdue for a new playbook. Today: the solutions he thinks might actually work.
