Thrilled to be speaking at @reconmtl 2025 for the 20th anniversary!. My talk is "Call, Crash, Repeat: Hacking WhatsApp" and covers my reverse engineering efforts and the bugs I've found in deeplink handling, PJSIP usage, and XMPP signalling. Hope you find it interesting 🥳

On vacay in Taipei and I heard TSMC engineers place these chips (乖乖) next to their computers for good luck. Hoping they boost my odds of getting this talk on WhatsApp bugs past the CFP stage!

Focused on iOS research rn - pleasently surprised to see that user data persists when downgrading apps with TrollStore. i.e. Find bug in v7 - app auto updates to v8 - force downgrade to v7.0 with TrollStore - user data persists. For when you forget to turn off updates . 🤦♂️.
