## Resource

Serge Humpich is a hacker who discovered a flaw in the Carte Bleue system used in France for credit cards. He tried to warn banks, but was unsuccessful, and therefore decided to perform a public "show" where he bought subway tickets while using the flaw in the card system. He was convicted in 2000 to a ten months suspended sentence, and lost his job as a result of the case. In this episode, Humpich joins host Heather Engel to discuss his experience, the ethical hacking landscape over 25 years later, and more. • For more on cybersecurity, visit us at https://cybersecurityventures.com
