A few years ago, a ransomware gang called LockBit rose from obscurity to extort over $100 million from organizations around the world. A security strategist named Jon DiMaggio wanted to understand how the organization worked. So he used the techniques of World War II-era spycraft to make contact with the hackers.

On today’s show, Jon tells the story of LockBit – from the way it borrowed techniques from mainstream companies to market itself and attract talent, to the response from international governments that used the gang’s own tactics against it. And he talks about how he got the hackers to talk to him.

Jon described the rise and fall of the company in a series of posts he called the Ransomware Diaries. You can read those here: https://analyst1.com/ransomware-diaries-volume-1/

Jared Baeten is senior vice president in virology at Gilead Sciences. Jared's problem is this: In a world without a vaccine, how do you make a medicine that people will actually take to help prevent HIV?

There’s already a daily pill that reduces the risk of getting HIV, but a majority of people who are at high risk are unwilling or unable to take it.

So Jared and his colleagues are developing a new drug, lenacapivir, designed to be given as a shot once every six months.
