Good Morning! Just published a blog post diving into Windows Kernel LFH exploitation in the latest Windows 24h2 build, Focusing on controlled allocations to achieve arbitrary read/write in the kernel. r0keb.github.io/posts/Modern-(…
This is a great read for people interested in hypervisor development in both pre-boot and post-boot (Windows) environment, the source is public and written in rust as well. Great work @memn0ps 😀🙌 github.com/memN0ps/matrix… github.com/memN0ps/illusi… memn0ps.github.io/hypervisors-fo…
The embargo (12:00 UTC 2025-06-10) is over, let's start a thread on Hydroph0bia (CVE-2025-4275), a trivial SecureBoot and FW updater signature bypass in almost any Insyde H2O-based UEFI firmware used since 2012 and still in use today. English writeup: coderush.me/hydroph0bia-pa…

with offensivecon around the corner, i figured id write another post on linux kernel exploitation techniques - this time i cover the world of page table exploitation! enjoy 🤓 sam4k.com/page-table-ker…
Two new side-channel attacks against Apple CPUs that can leak sensitive data from the processor's memory SLAP (Speculation Attacks via Load Address Prediction) and FLOP (False Load Output Predictions) predictors.fail

Nice paper! 🔥 No fix implemented, AFAIK. Like the general idea that leaking the address of an exploit-controlled object of one type effectively means leaking the address of an object of another chosen type, as we can put the latter object onto the same page via cross-cache.

New attack on x86 secure enclaves, specifically AMD SEV this time. SEV is AMD's answer to Intel TDXs. Basically tricking the CPU into thinking the DRAM is a different size, causing physical address aliasing, which can then be exploited

Outrageous technique: barely legal use of x86 CPU instruction enables you to catch and 𝗰𝗮𝗻𝗰𝗲𝗹 impeding pagefault before it actually happens. ③: catch PAGE_GUARD or invalid access ⓪: do previously illegal reads at high IRQL, safely #vpgatherqq #vpscatterqq scatter/gather
Created a blog post explaining physical memory primitives, how they can be exploited and how we can abuse the address translation mechanism to access any memory on a system as well as inject code into any process. 0dr3f.github.io/Demystifying_P…
