Slides from my lecture today on the ZIP file formats looked at from various sides (though mostly security related):

Download: slides (1.7 MB)
Files: files (46 KB)

EDIT: I've uploaded the weird ZIP files (examples, scripts, exploits, etc) I've used/shown on my presentation.

EDIT 2:
I've re-done the talk during one of my livestreams. Here's the archived video:

@Alex
There is an unofficial bootleg-style recording from Sebastian:
https://www.youtube.com/watch?v=9YYVl2wztlo (first few minutes, low quality)
https://youtu.be/LHN6sy0TNZw (the rest, higher quality)

I plan to re-do this talk on my livestream in a few weeks (according to the calendar linked at https://www.youtube.com/user/GynvaelEN/about it will happen on 9th of May).

@Marc
Thanks! :)
