Had an amazing experience at @1ns0mn1h4ck this year, talking about adding NVMe-of/TCP to syzkaller. In case you want to check it out: Here’s the recording - m.youtube.com/watch?v=Jc25CM… And the slides - download.scrt.ch/insomnihack…

Quite a few people asked me if we’ve found more vulnerabilities in the NVMe Linux kernel driver. So, here is my answer! Check out the blog post of my colleague Alon on his journey of fuzzing the driver with some lovely findings!
Be sure to check out my recent blog about my latest research “Your NVMe had Been Syz’ed”. In there I show how to add new subsystems to syzkaller, and how to use it to find new vulnerabilities. cyberark.com/resources/threa…

Interesting reading on how to use Static Code Analysis tools for finding vulnerabilities (with a NULL Pointer Dereference in the NVMe driver of the Linux kernel as practical example) Credits @TalLossos (@TalLossos) cyberark.com/resources/all-b… #Linux #kernel #infosec

Did you know that NVMe over TCP exists? I sure didn't, but it's a super interesting attack vector. @TalLossos just put out an excellent blogpost of using CppCheck to find a null pointer deference in the Linux kernel’s NVMe driver. Check it out! cyberark.com/resources/threa…

Replying to @OmerTsarfati
@OmerTsarfati and I harnessed ChatGPT to create a #polymorphic #malware, which uses ChatGPT on runtime to load and mutate new code that easily bypasses the content-filter. We are looking forward to continuing and research the topic -:) cyberark.com/resources/threa…
