Offensive eBPF - From Input Events to a Basic bpftrace Keylogger

While the extended Berkeley Packet Filter (eBPF) it is frequently used for performance monitoring and networking, its ability to attach to almost any kernel function makes it a potent tool for security research and, theoretically, for building stealthy surveillance tools like keyloggers. In this post, we will build a keylogger from scratch using bpftrace. We will move from blind reconnaissance to

A Byte-wise Understanding of eBPF CO-RE

eBPF has revolutionized Linux kernel tracing and security by allowing user-space programs to safely execute in kernel space, but its power has historically been limited by strict kernel version dependencies. When a kernel structure changes between updates, hardcoded memory offsets break, leading to crashes or silent failures. To overcome this fragility, the ecosystem introduced BPF Type Format and
