Iterating Exploits & Extracting SGX Keys Sep 16, 2024

Show notes

We are back and testing out a new episode format focusing more on discussion than summaries. We start talking a bit about the value of learning hacking by iterating on the same exploit and challenging yourself as a means of practicing the creative parts of exploitation. Then we dive into the recent Intel SGX fuse key leak, talk a bit about what it means, how it happened.

We are seeking feedback on this format. Particularly interested in those of you with more of a bug bounty or higher-level focus if an episode like this would still be appealing? If you want to share any feedback feel free to DM us (@__zi or @specterdev) or email us at media [at] dayzerosec.com
