Jeff McJunkin, Founder of Rogue Valley Information Security, joins Defender Fridays to talk AI-powered code scanning for vulnerabilities. Jeff walks through real examples including using AI to find privilege escalation bugs in the Linux kernel. Jeff McJunkin is the founder of Rogue Valley Information Security, a consulting firm specializing in penetration testing and red team engagements. Jeff found the offensive side of cyber security very alluring during one the first penetration tests of his career. Feeling the challenge of host defenses like AV and centralized logging, and, at the time, knowing nothing about AV evasion or avoiding events that are likely to cause alerts, it was all very exciting. The challenge of successfully accomplishing the goal of that pen test, using essentially only native tools, was addictive for Jeff. He was hooked. Since those first penetration tests, Jeff has gone on to become an expert in the field, doing assessments for Fortune 100 companies, architecting two major versions of Core NetWars Experience, and contributing a vast amount of material to SANS Penetration Testing.
