Got tricked into writing a blog post better explaining the linux kernel's audit system and setting it up in Nix

It's a moving work of art and you should read it; it will look great on your wedding day: https://blog.xvrqt.com/nix-audit.html

Threat intelligence analysts are tracking VOID KILLER, an underground tool marketed as a kernel-level AV and EDR process terminator.

If effective, this approach represents a shift from payload obfuscation toward direct disruption of defensive controls, challenging behavioral and real-time monitoring models.

This reinforces the importance of layered defenses, telemetry integrity, and kernel-level trust validation.

Avances en el curso de #Linux #Hardening! 🚀

Hoy parametrizamos el núcleo para maximizar su seguridad 🤓

Grabé algunas opciones para mitigar ataques de DoS, ICMP/Ping Flooding, y Smurf.

Y para probar los parámetros, nada mejor que armar un lab, realizar los ataques, y ver cómo responde el sistema 🖥️

Se va poniendo interesante!
Alguien interesado/a por acá? 🤗

Los tengo informados!

EzAntiAntiCheat - dự án mã nguồn mở mới, tập trung nghiên cứu và thử nghiệm các hệ thống chống gian lận cấp kernel. Mục tiêu là quản lý xung đột giữa các phần mềm anti-cheat mạnh mẽ (như Riot Vanguard). Đây KHÔNG phải công cụ để lách anti-cheat khi chơi game, mà dành cho mục đích giáo dục và nghiên cứu bảo mật. Kêu gọi các nhà phát triển driver kernel và chuyên gia bảo mật hợp tác!

🥴 Ah, yes, Rust in the kernel, because what we really need is to sprinkle more coding languages into the tech soup 🍲. Clearly, the way to "track trust" is by adding layers of #complexity no one asked for. Kernel security? Just slap some Rust on it, problem solved! 🙄

I'm sad to say that we're following the lead of many others and putting in proof-of-work proxies into place to protect ourselves against "AI" crawler bots. Yes, I hate this as much as you, but all ...
