🔍 eBPF Rootkits ranges from Research to Underground Tradecraft A sponsored eBPF rootkits writing highlights forum tutorials and shared code for Linux rootkits using BPF interfaces supported by the kernel instead of kernel modules to load. Advanced techniques include the obfuscation process using Getdents64s, packaged execution, XDP-based traffic inspection, and filtering associated with anti-virus linked IP lists. Practically, this is important because the abuse of EBPF merges into legitimate kernel mechanisms and can evade the checks built around module loadings. The article also notes previous cases such as BPFDoor and LinkPro, and emphasizes that these methods are no longer limited to demonstration at a conference. 🛰️ Open sources - closed narratives.
