A few months ago I flew to New York to film in the Good Morning America studio, for a segment on the "grandparent scams" where bad actors use AI to impersonate family members and steal money. Last night it aired on Nightline! 🥳 Incredible opportunity, thank you for having me!💙

Lotta chatter around #ScreenConnect vulnerabilities now as folks are getting spun up. Fellow Huntress researchers and I were up all night to recreate the auth bypass and RCE exploit. I'm not a huge fan of giving a PoC to threat actors, but I do dig snazzy video demos 😜
