Earlier this year, I was thrilled to hear that my submission for a talk at this year's [FrOSCon](https://www.froscon.de/) (Free and Open Source Software Conference) was accepted. [The talk](https://programm.froscon.de/2019/events/2350.html) is about Ghidra, the reverse engineering tool which was recently release into open source by the NSA. Since I expected a very heterogeneous audience with people from all kinds of industries with all kinds of backgrounds, I decided to give a long introduction with a lot of motivation for reverse engineering and only use the last quarter or so of the talk to actually show Ghidra's capabilities.
You can find the [slides here](https://blag.nullteilerfrei.de/wp-content/uploads/2019/08/FrOSConTalk2019-Ghidra.pdf), the source [of the slides on github](https://github.com/larsborn/FrOSCon2019-Ghidra-Talk) and a recording at [media.ccc](https://media.ccc.de/v/froscon2019-2350-ghidra_-_an_open_source_reverse_engineering_tool). Based on feedback after and during the talk, I added a bullet point under Motivation: a lot of people at FrOSCon seemed to be in the position where a wild binary blob appeared and they had to deal with it. Some because they found an old service running with source code not available (or readable) anymore and some because they want to re-implement a protocol that is not documented.
