    I organized my notes and made it into slides when I learn about segment heap . If you find something wrong, please let me know. Hope it can be helpful fo those who want to learn segment heap in windows kernel.

    Here is my challenge in WCTF 2019. github.com/scwuaptx/LazyF…
 Hope everyone can learn more windows heap from this challenge. About windows 10 NT heap slideshare.net/AngelBoy1/wind… I only write Chinese version slide, I will release an English version soon.

    My exploit for my challenges at HITCON CTF 2020 github.com/scwuaptx/CTF/t… Lucifer challenge is a segment heap challenge in windows kernel. You need to use named pipe to spray in nonpaged pool and use it to do arbitrary memory reading. Hope everyone can learn more from our CTF.

    Nice writeup from LC↯BC for my windows kernel challenge "breath of shadow" !

In my intended solution, you need to deal with "KVA Shadow" so that you can jump to shellcode in userspace.
 Thank you for solving my challenge :) #hitconctf

    Although I did not find useful vulnerabilities in other targets and other attacker surface, it was a good experience for me. The most important thing is that I learned a lot during the research. Hope I can find more vulnerabilities in the future.
    I am surprised that we won the #Pwn2Own 2021 because we only registered for one entry. But we are actually the only team (out of 3 teams) got the full-win on Exchange Server! Thanks to the lucky draw results and my awesome @d3vc0r3 research team member @mehqq_ and @scwuaptx!
