Just published a follow-up to my Adobe Reader symbols story on the Project Zero blog. Turns out there's even more debug metadata to be found in some old (and new) builds, including private CoolType symbols. Enjoy! googleprojectzero.blogspot.com/2020/01/part-i…

We updated the Security Servicing Criteria for Windows today clarifying a non-boundary (Hyper-V Administrator Group) & expanding the Administrator-to-Kernel non-boundary.
We do this periodically in response to research trends; feedback is always welcome.

The 7th part of the tutorial Hypervisor From Scratch is published!
In this part, I described EPT.
Thanks to Petr @PetrBenes as Hypervisor From Scratch could never have existed without his help and to Alex @aionescu for patiently answering my questions.

Awful. Thank you for sharing. Hopefully, making those bad behaviors public will help eradicating them over time...

Old news, but just for fun - the fact that the XMMs registers aren't reset (by the calling convention) is quite useful for pwns in CTFs. And not only for controlled data or heap addresses, libc as well ;)

Let's unearth my 'old' unpacking knowledge...
IIRC the only doc I publicly made on the topic was github.com/corkami/docs/b…
Which doc/tool would you recommend checking nowadays? #unpackingparty pic.twitter.com/D91TwYdGCH

I gave it twice: the first time really well, the second time was a bit harder (people with very different backgrounds), but I got good feedback :) :) I will give it again next year.
