Episode 61: In this episode of Critical Thinking - Bug Bounty Podcast Justin is joined by Jasmin Landry to share some stories about startup security, bug bounty, and the challenges of balancing both. He also shares his methodology for discovering OAuth-related bugs, highlights some differences between structured learning and self-teaching, and then walks us through a couple arbitrary ATO’s and SSTI to RCE bugs he’s found lately.
