Intro to Common Industrial Protocol Exploitation
Trevor Flynn
DEF CON 33 · Day 1 · Main Stage
Trevor Flynn's DEF CON talk, "Intro to Common Industrial Protocol Exploitation," provides a foundational yet detailed exploration into the Common Industrial Protocol (**CIP**), a cornerstone communication standard for industrial control systems (**ICS**). The presentation demystifies CIP, explaining its architecture, object-oriented nature, and unique networking capabilities, particularly its routing mechanisms that can traverse disparate network types. Beyond the theoretical, Flynn delves into practical methodologies for discovering vulnerabilities in CIP-enabled devices, primarily through **fuzzing**.
AI review
Flynn delivers a competent, well-structured introduction to CIP internals and fuzzing methodology that gives OT-adjacent security folks a genuine foothold in the space. The content is real and the technical grounding is honest, but 'intro' is the operative word — this is foundational education, not novel research, and it reads like exactly what it says on the tin.
