There is a constant arms race between law enforcement and criminals, especially when it comes to technology. For years, law enforcement has been frustrated with encrypted messaging apps, like Signal and Telegram. And law enforcement has been even more frustrated by encrypted phones, specifically designed to thwart authorities from snooping.

But in 2018, in a story that seems like it's straight out of a spy novel, the FBI was approached with an offer: Would they like to get into the encrypted cell phone business? What if they could convince criminals to use their phones to plan and document their crimes — all while the FBI was secretly watching? It could be an unprecedented peek into the criminal underground.

To pull off this massive sting operation, the FBI needed to design a cell phone that criminals wanted to use and adopt. Their mission: to make a tech platform for the criminal underworld. And in many ways, the FBI's journey was filled with all the hallmarks of many Silicon Valley start-ups.

On this show, we talk with journalist Joseph Cox, who wrote a new book about the FBI's cell phone business, called Dark Wire. And we hear from the federal prosecutor who became an unlikely tech company founder.

We are living in a kind of golden age for online fraudsters. As the number of apps and services for storing and sending money has exploded – so too have the schemes that bad actors have cooked up to steal that money. Every year, we hear more and more stories of financial heartbreak. What you don't often hear about is what happens after the scam?

On today's show, we follow one woman who was scammed out of over $800,000 on her quest to get her money back. That journey takes her from the halls of the FBI to the fraud departments of some of the country's biggest financial institutions. And it offers a window into how the systems that are theoretically designed to help the victims of financial cybercrime actually work in practice.

This episode was hosted by Alexi Horowitz-Ghazi and Jeff Guo. It was produced by Willa Rubin and edited by Keith Romer. It was engineered by Neal Rauch and fact-checked by Sierra Juarez. Alex Goldmark is Planet Money's executive producer.
