Classic. At #HackLu this morning one of the housekeeping announcements was if whomever changed the digital labels on the coffee machine could please change them back again as that would save them from calling a technician.

I've failed to post the #HackLu videos here because they only have a presence _there_ and on Mastodon.
Today I'll be correcting that, so word of warning: Backlog of ~50 video posts incoming, and another 20-ish for the talks of today.

I presented at HackLu about oddities of existing file formats and lessons learned along the way.
Consider it a teaser, as I presented 1/3 of the slide deck (to be released soon).

This talk from @wr is a masterpiece if you want to dive into all the gory details of the X.509 certificate format.

When working on Magika (Google's AI-powered content-type detection), I checked other file formats KBs and detection engines to create filesets to train the model on.
I gave a talk at HackLu to share an overview of the existing engines.

Seeing a presentation of the Kaitai project.

If you need to document or describe or decode binary format, Kaitai is clearly there to help.

At hack.lu I gave a presentation about "How to better identify (weaponized) file formats":

- Why do we need to identify file formats accurately?
- Why can the current tools (libmagic, magika) sometimes be bypassed?
- How can we do better?
