We kicked things off by talking about the Holiday Hack Challenge, which is like this massive cyber playground that Sans puts out every year for everyone from fifth graders to government spooks. Ed Skoudis broke down how they're changing things this time, with an early release and a phased approach that'll give you more time to play and learn. But the real mind-bender was when Ed spilled the beans on how they build this whole thing using one giant Google sheet - I mean, we're talking hundreds of tabs, color-coded cells, and JSON to create entire virtual worlds. Then we covered the rest of the security news including hacking Mazda's infotainment system and more! Segment Resources: https://sans.org/holidayhack Show Notes: https://securityweekly.com/psw-851
