In this episode of Critical Thinking - Bug Bounty Podcast, we're thrilled to welcome Frans Rosén, an OG bug bounty hunter and co-founder of Detectify. We kick off with Frans sharing his journey bug bounty and security startups, before diving headfirst into a host of his blog posts. We also cover the value of pseudo-code for bug exploitation, understanding developer terminology, the challenges of collaboration and delegating tasks, and balancing hacking with parenting. If you're interested in bug bounty or entrepreneurship, you won't want to miss it!
