312: Two Meter Exhaust Port
Hosts Elecia White and Christopher White discuss how security vulnerabilities are exploited in embedded systems, using a fictional VoIP speaker phone as a case study for threat modeling. They explain the mechanics of buffer overflow attacks, detailing how stack corruption allows attackers to execute arbitrary code, and cover injection prevention and the risks of insecure firmware update mechanisms. The conversation emphasizes the importance of OWASP Embedded Application Best Practices, securing sensitive data, and conducting threat modeling to balance security with manufacturing constraints.
