The Binary Analysis Tool is an Open Source framework for analysing arbitrary binary files, such as firmwares, flash dumps and executables. The Binary Analysis Tool has proven to be especially useful in situations where software is purchased from a third party in binary only form and it needs to be checked for presence of open source code before shipping the code out. In this talk I want to present the (scientific) backgrounds and history of the Binary Analysis Tool, highlight why this tool is needed, when and where it can be used (and when not), how it fits into a procurement and compliance process, as well as give an extensive demo of the Binary Analysis Tool in action.
