What it detects

This rule detects PowerShell adding Microsoft Defender exclusions for cryptomining components used by the DeceptiveDevelopment cluster after a ClickFix fake-interview lure. Attackers whitelist TsunamiClient and XMRig paths so the dropped miners run undetected, and matching this behavior surfaces active defense evasion before mining begins.
