@DefSecSentinel has been knocking it out of the park on X this year. That has translated nicely to his talk at #OBTS - great to see folks focussing on the behavioural detection side of the world 🍎

It never fails to amaze me how frequently ex-MWR researchers are referenced during conference talks 😍 Got to love seeing @alexjplaskett's name come up during @FuzzyAleks's talk into "Triangulating TrueType Fonts On macOS: Reconstructing CVE-2023-41990".
