ICYMI: The DEF CON 33 Hackers' Almanack is out now. Hackers have made it clear what policymakers should know and quickly act upon. It's time to start listening to what the experts have to say⬇️ harris.uchicago.edu/sites/defaul... #CyberCivilDefense #Take9 #HackersAlmanack

👏Great breakdown coverage of the Hackers’ Almanack by Sara Friedman in Inside Cybersecurity. Hackers laid it out, now it’s time for policymakers to act. Read more ⬇️ insidecybersecurity.com/share/17782 DC 33 Almanack⬇️ harris.uchicago.edu/sites/defaul... #CyberCivilDefense #Take9 #HackersAlmanack

More kudos to @politico.com for this coverage of the Almanack. It features themes and policy solutions, from creating multilateral standards for AI use in cyber to fighting back against despotism with digital means. Link in bio. @defcon.bsky.social #CyberCivilDefense #Take9#HackersAlmanack

My DEF CON talk on DIY web archiving and SUCHO made it into the annual publication, the Hackers' Almanack (p. 10)! All in all, it's a very accessible summary of major trends and highlights from the conference, worth checking out! harris.uchicago.edu/sites/defaul...

oh cool, the hackers' almanack from def con 33 is out... and seems like they think policymakers should know about our snitch puck research? (i agree, naturally, but the outside validation is nice)

🎉Thanks to the @politico.eu Cyber Insights newsletter for being the first to cover the Almanack! The threats are real. The systems are fragile. The gap between what hackers know and what governments act on is still wide. Read here⬇️ harris.uchicago.edu/sites/defaul...
