Next in our drone security series: having the right security mechanisms doesn't always mean they'll withstand a physical attack. From encryption to secure boot and readout protection, we explore why testing the actual implementation matters. eshard.com/blog/drone-securi…

Part 2 of our Android kernel exploit chain (CVE-2023-20938): the stale read returns garbage until you control what reclaims the freed slot. Land the right object there and it hands back a live kernel pointer instead. That’s your KASLR bypass. eshard.com/blog/kernel-uaf-2…

We tested Botan 3.7.1’s ECC from source code to EM attacks on an iMX 8. Constant-time on paper wasn’t constant-time on silicon: a timing leak and a table lookup leak both worked on real hardware. Accepted at HS3 @ ESORICS 2026. eshard.com/blog/botan-physic…

Lite VM Studio builds a quiet Windows VM from one prompt: emulation CPU drops from 86% to 1.3% of a host core on Windows 10, about 66x less noise. 🔗 See how we did it: eshard.com/blog/lite-vm-stud…
