Windows Defender ATP runs on over 2 million devices and combines host telemetry with cloud analytics; the talk demonstrates concrete evasion and disabling techniques that work in current releases. Examples include HKCU COM hijack to get persistent, signed-scriptlet execution that bypasses AMSI/ScriptBlockLogging; DLL hijacking or crashing of senseproxy and adding firewall rules to block Microsoft cloud endpoints to stop telemetry; using WMI/CIM for local-only AD recon, SPN enumeration plus silver tickets to avoid DC auth, and ephemeral golden tickets/AES keys to dodge ATA alerts.
