Here's one more #ThrowbackThursday pic for you, and it's gonna throw you waaaaay back: this is what the #WallofSheep looked like at the beginning. All we had was a stack of paper plates, a homemade sign, some tape, and determination. 21 years later.... we've all come a long way!
I’ve had to explain to several folks what #badgelife is lately. I’ll just show them this from now on.

State Dept warns Americans to leave Ukraine: "information that Russia is stepping up efforts to launch strikes against Ukraine’s civilian infrastructure and government facilities in the coming days....US Embassy urges US citizens to depart Ukraine now" ua.usembassy.gov/security-alert…
Using my favorite @DEFCONPolicy swag, thanks @RoRoRah!
I’m still not functional after #HackerSummerCamp, anyone else?
“LAS VEGAS, Aug 17 (Reuters) - A team of hackers from two U.S. universities won the "Capture the Flag" championship, a contest seen as the "Olympics of hacking," which draws together some of the world's best in the field.” Nice article about @defcon CTF
NEW: Last week, hackers targeted 1,900 Signal users, specifically going after three of them. I was one of those three, and the hackers were able to take over my Signal account for 13 hours. Here's how we responded to this incident. vice.com/en/article/qjk…
Yes! I’m reinvigorated to get back to #BadgeLife. It’s been a while since I designed anything.
