Ensure 'Proxy settings' is set to 'Enabled' and does not contain "ProxyMode": "auto_detect"
Description
Google Chrome offers the functionality to configure the proxy settings by automatic discovery using WPAD (Web Proxy Auto-Discovery Protocol). Setting this configures the proxy settings for Chrome and ARC-apps, which ignore all proxy-related options specified from the command line. Disabled (0): Lets users choose their proxy settings. Rationale: Attackers may abuse the WPAD auto-config functionality to supply computers with a PAC file that specifies a rogue web proxy under their control. Compliant when the proxy policy is configured (ProxyMode or ProxySettings under HKLM\SOFTWARE\Policies\Google\Chrome) and neither selects auto_detect.
