Journey of ICS Project Files: Visibility and Forensics

In this technical reverse engineering session from the DEF CON Safe Mode ICS Village, a security researcher explores the forensic value and security risks of Industrial Control System (ICS) engineering project files. Opening at 00:00, the speaker introduces project files as rich repositories containing full plant architectures, PLC logic, I/O tag databases, and network topologies.

At 12:00, the presenter demonstrates how threat actors weaponize project files during reconnaissance to identify vulnerable controllers and map critical process tags prior to executing targeted physical disruption.

At 24:01 and 36:00, the talk dives into proprietary binary file formats, revealing how parser flaws and embedded database vulnerabilities in engineering workstations allow attackers to plant malicious payloads directly within project archives. Concluding at 48:00, the speaker urges defenders to treat ICS project files with the same scrutiny as executable macro files, establishing strict validation and sandboxing procedures before opening them on engineering stations.
