Hunting Rootkits with eBPF: Detecting Linux Syscall Hooking Using Tracee

Today, cloud native platforms are increasingly using eBPF-based security technology. It enables the monitoring and analysis of applications’ runtime behavior by creating safe hooks for tracing internal functions and capturing important data for forensic purposes. Tracee is an open source runtime security and forensics tool for Linux that is powered by eBPF and is more …
