Message in a Broken Bottle - Exploring the Linux IPC Attack Surface

Explore the Linux IPC attack surface in this 35-minute Black Hat conference talk. Dive into the world of systemd and its communication with other system services through IPC, focusing on the central role of dbus-daemon as a message bus. Examine the potential vulnerabilities in this micro-kernel-like design where most of the operating system is implemented as userspace processes. Gain insights into the interactions between systemd and other critical system services such as polkit, accountsservice, UDisks2, and aptd. Presented by Kevin Backhouse, this talk offers a comprehensive look at the security implications of Linux's IPC architecture and its potential attack vectors.
