Link: Google share.google URL shortener in google.<tld>/share.google path form

Description

Detects inbound messages with body links in the form google.<tld>/share.google?q=<code>, which inherits google.<tld> domain reputation to mask an attacker-controlled destination. This google.<tld>/share.google?q= path form is undocumented: Google publishes the share.google shortener feature, but not this on-Google-domain form or its 'q' parameter.
