Fileless ELF Execution via O_TMPFILE · 0xMatheuZ
O_TMPFILE creates anonymous inodes on real filesystems with no directory entry. Combine it with execveat(AT_EMPTY_PATH) and you get fileless ELF execution that looks nothing like memfd_create in …

What are physical side-channel attacks: how electricity can accidentally become a data channel. 📟⚡🔬👨🏻🎓🏆
Embedded security researcher Benedikt Gierlichs gave a lecture about physical attacks and, in particular, side-channel attacks: what they are, how they work, and the core principles of side-channel attacks.
The lecture is about something that you can rarely find in presentations and research papers - it is a source of solid foundational knowledge for understanding how systems become vulnerable to side-channel attacks in the first place.
No matter how advanced you are in hardware hacking, I really recommend that you invest those 43 minutes and watch this lecture. You will learn something new and very useful.
Enjoy!

Escaping the Red Hat Cult: Why I'm Done with SystemD and Wayland
I desire to break free from the Red Hat cult and explain why I’m ditching systemd, Wayland, GNOME, and the bloated Linux stack that’s taken over modern distros. I make the case for returning to the Unix Philosophy—small tools that do one thing well—and showcase…
