eBPF Linux: XDP Packet Filtering, Kprobes Runtime Tracing & Kernel-Level Malware Detection
eBPF executes verified bytecode at kernel hook points — kprobes, tracepoints, XDP driver level — with JIT-compiled native performance and no module stability risk. XDP intercepts packets before the kernel networking stack for DDoS mitigation at millions of packets/second. Kprobes attach to any kernel function for real-time syscall argument tracing. Security application: behavioral detection that captures syscall sequences regardless of compiler artifacts or CFG obfuscation — the only reliable detection layer against pure assembly implants.
