Kernel ETW is the best ETW
This technical article examines Event Tracing for Windows (ETW), a logging mechanism used by Windows components and security products to monitor privileged operations. The piece compares kernel ETW providers, which offer stronger anti-tampering guarantees, with less reliable user-mode approaches, and catalogs four types of ETW providers (modern and legacy event providers, and modern and legacy trace providers). The author provides guidance on discovering and analyzing kernel ETW events through decompilation, metadata extraction, and reverse engineering techniques.
Why it matters: Security practitioners and endpoint detection and response (EDR) developers should understand kernel ETW capabilities and limitations to evaluate telemetry reliability; kernel-sourced events are significantly harder to bypass than user-mode equivalents, making them critical for detecting adversary actions that attempt to evade hooks or tamper with logs.
