About
I Meysam, a software security researcher, with expertise in hypervisors, Windows, Unix-based systems, and XNU(macOS and iOS) you can find some of my old exploits I have written in here and here
Some vulnerabilities I’ve reported include an intriguing story behind them. for example CVE-2016-0040, which you can read in Microsoft’s blog post
And story of a vulnerability collision with in the wild exploits in the CVE-2022-22587(iOS/macOS kernel memory corruption), media and news coverages:
I also became one of the Microsoft’s 2020 Most Valuable Security Researchers( ranked #40)
