endrift 🏳️⚧️Happy 25th Birthday to the Game Boy Advance! Feels weird that mGBA is roughly the age now that the GBA was when I first started working on it.

and this I learned about because Microsoft had a bug in their implementation that allowed an attacker to perform a memcpy as the Defender process

Exploiting the Windows Defender `AsProtect` Heap Overflow Vulnerability | PixiePoint Security
In the security updates of June 2021, Microsoft patched a heap buffer overflow in the Windows Defender mpengine.dll assigned as CVE-2021-31985. The vulnerability was found by Google Project Zero (GP0) and reported on May 25, 2021. The Windows …
it's for ASProtect which has apparently been studied by many, and microsoft has even written an unpacker for it (so that Defender can peek inside) but for which seemingly no one seems to have published any tools (just some hacky ollydbg workflows)
how many IDA Pro windows is too many?
1. packed dll
2. dll embedded in 1
3. exe in whose context I can observe unpacking of 1
4. merge of 1 and 2
5. simpler exe to test 4 in

GDC Presentation ReviewsGDC 2016: "Rendering 'Rainbow Six | Siege'" by Jalal Eddine El Mansouri of Ubisoft Montreal https://gdcvault.com/play/1023287/Rendering-Rainbow-Six-Siege
This presentation was a bit challenging to follow. There were 2 main topics of the presentation:
1. They try really really hard to reduce the number of draw calls they use. They do this in two ways: GPU-based culling (which seemed fairly standard to me), and by merging resources. For example, they have a single vertex buffer for the entire map.

Gabriele SveltoA few years ago I designed a way to detect bit-flips in Firefox crash reports and last year we deployed an actual memory tester that runs on user machines after the browser crashes. Today I was looking at the data that comes out of these tests and now I'm 100% positive that the heuristic is sound and a lot of the crashes we see are from users with bad memory or similarly flaky hardware. Here's a few numbers to give you an idea of how large the problem is. 🧵 1/5
