Core checksums
For the checksum comparison, WordPress/WM Guard sends the installed WordPress version and package locale to the official WordPress.org checksums API. Results are cached for twelve hours.
Plugin directory
To check for closed or long-unmaintained plugins, the respective plugin identifier is sent to the official Plugin Info API. Results are cached for 24 hours.
Neutral user agent
WM Guard uses a neutral WM Guard/<version> user agent for these requests. This avoids the standard WordPress user agent that can normally contain the site address.
