Detection: Memory Forensics and Hardening
- Memory forensics (Volatility): dump RAM and analyze it offline —
pslist (list walk) vs psscan (pool tag scan) reveals DKOM-hidden processes; ssdt, modules vs modscan expose hooks and unlinked drivers. - Driver Signature Enforcement (DSE): 64-bit Windows refuses unsigned kernel drivers — the hurdle Stuxnet dodged with stolen certs.
- PatchGuard / Kernel Patch Protection: on x64 Windows, periodically checks core structures (SSDT, IDT, key code) and bugchecks if patched — killing classic SSDT hooking.
- Secure Boot + TPM measured boot: verify firmware and boot loader signatures to stop bootkits/UEFI implants.
