gallia is an extendable pentesting framework with the focus on the automotive domain, developed by Fraunhofer AISEC under the Apache 2.0 license. The scope of the toolchain is conducting penetration tests from a single ECU up to whole cars. Currently, the main focus lies on the UDS interface but is not limited to it. Acting as a generic interface, the logging functionality implements reproducible tests and enables post-processing tasks.
The following blog post introduces gallia’s architecture, its plugin interface, and its intended use case. The post covers the interaction between its components and shows how gallia can be extended for other use cases.

A digital twin is a virtual representation of a real system or device. It accompanies its physical counterpart during its entire life cycle. Tests, optimization procedures and bug hunting can be carried out on the twin first without involving the real device (that may not even exist at that moment). In this article, I want to give you some recommendations on how to harness that potential for improving upon the state of OT security (Operational Technology Security), e.g., within manufacturing or building automation.
