Turmio / Mikko Kenttälä
My journey to find vulnerabilities in macOS. During 2020 and 2021 I found two major vulnerabilities from macOS. In this presentation I walk you through the whole exploit chain to compromise users' sensitive data with one click. I will also explain my methodology to find logic bugs.
My journey to find vulnerabilities in macOS. During 2020 and 2021 I found two major vulnerabilities from macOS. In this presentation I walk you through the whole exploit chain to compromise users' sensitive data with one click. I will walk you through how I solved the following steps: - Fundamentals how I find vulnerabilities - Basics about the "extra" security protections in macOS - How to get payload delivered with one click - Code execution with arbitrary mount - Gatekeepper evasion - TCC protection evasion - SIP -protection evasion - Timeline - How Apple will credit the researches

This is a submission for a keynote talk at MCH2022. The Internet is both a familiar, comfortable place as well as a bottomless rabbit hole you can lose yourself in. The Internet has always been like this from its inception, the difference now is the scale and consequences are almost immeasurable - and it tests the limits of human imagination. When you look into the mirror of the Internet what you see reflected back depends on what you are looking for. It has become largely a reflection of ...

Have you ever forgotten a passphrase or lost a hardware token? Lost access to enough Bitcoin to buy a pizza or two? Encryption is fundamental to securing our liberties, but key and password management remain difficult even for professionals, let alone the general public. This talk presents Passcrow, an Open Source project attempting to address one of crypto's largest usability issues: password and key recovery in a decentralized environment.

The real problem however, is integration with existing protocols, instead of inventing something completely new and perhaps web-only. The purpose of our work on Realm Crossover mechanisms has been to design generic solutions that extend many different application protocols, without changing their protocol specs.
