Here are my DEF CON notes from the sessions that I attended in 2025 for DEF CON 33:

• DEF CON 33 Notes & References (PDF)

Please feel free to do what you want with these notes.  I go to sessions, so you don’t have to.

Here are some quick links to notes from previous years: 32 (2024), 31 (2023), 30 (2022), 29 (2021), 28 (2020)*, 27 (2019), 26 (2018), 25 (2017), 24 (2016), 23 (2015), 22 (2014), 21 (2013), 20 (2012), 19 (2011), & 18 (2010). 

*I have 28 (2020) notes, but they still need work.

I plan on attending DEF CON 34 (2026). Best way to follow real time going forward is: Steve Holden (BlueSky).
