I found the talk: https://www.wallofsheep.com/blogs/news/list-of-packet-hackin... https://twitter.com/ebrinkster/status/1028085975887429639

It doesn't look like it's on YouTube unfortunately.

Ah, thank you! I had spent 15 minutes unsucessfully looking through the program for it.

I can't find his slides on the media server: https://media.defcon.org/DEF%20CON%2026/DEF%20CON%2026%20pre...

Usually everything from defcon is present. Weird.

Anyway, someone more motivated than me may be able to turn them up. Thank you for finding the speaker.

Seeing the no camera symbol in the twitter picture, I think it not being on the internet was done on purpose.
