Fun fact about this picture in the blog post by @thezdi , I was actually exploiting my personal phone, the Galaxy Z Flip 6, to make sure it would still work against the Galaxy S24. Fun times on stage

How many advisories did we publish in 2024? What was the top CWE? How many were 0-day? How much money did Pwn2Own award? You can find this - and more - in our 2024 retrospective. zerodayinitiative.com/blog/2025/2/7/…

Okay #stepmaniax calm down. You can't implement features like custom sensitivity. You'll make the other dance games jealous

This year I got my 10th CVE. My thoughts on CVEs, security research, and doing research in general.

10 CVEs! My Personal Thoughts On Research And CVEs
Samsung issued their January 2023 patch, which included 2 more CVEs assigned to me. That makes 10 CVEs so far in my security career.

Replying to @topjohnwu
Literally all of my Samsung device CVEs / mobile research were possible because of Magisk. I really don't know what the security research field would do without Magisk.
