A shocking data breach at a Finnish psychotherapy service. Jenny Kleeman traces the story of a nation’s secrets held to ransom by a faceless hacker.

This is what happened to Tiina, a Headteacher living near Helsinki. When decades of stress and anxiety overwhelmed her, she sought support through a therapy service called Vastaamo.

Vastaamo was accessible, affordable, and a national success story. But in September 2020, the company received an email from a hacker claiming to have stolen their entire patient database - including therapy notes.

Antti Kurittu is the cybersecurity specialist tasked with saving the secrets of 33,000 patients, but can he and the police find a way to stop this hacker, who calls himself ransom_man?

Before long, Antti, Tiina and a whole nation learn just how far he is willing to go.
