Title:Reverse engineering of PLC communication: Implications cyber forensics and security (Dr. Frank Breitinger)
Date:20.6.2017
On Tuesday, June 21, 2017 at 10 am there will be a research talk given by Dr. Frank Breitinger (University of New Haven, USA) at lab C304.

Abstract: Programmable Logic Controllers (PLCs) are common components implemented across many industries such as manufacturing, water management, travel, aerospace and hospitals to name a few. This presentation shows our findings from reverse engineering the GE-SRTP network protocol using a GE Fanuc Series 90-30 PLC and provide two major contributions: We first describe the Service Request Transport protocol (GE-SRTP) which was invented by General Electric (GE) and is used by many of their Ethernet connected controllers. Second, based on our understanding of the protocol, we implemented a software application that allows direct network-based communication with the PLC (no intermediate server is needed). While the tool's forensic mode is harmless and only allows for reading registers, we discovered that one can manipulate / write to the registers in its default configuration, e.g., turn off the PLC, or manipulate the items / processes it controls.
