This rule identifies and detects URLs linking to the Gamma App in presentation mode, which have become a target for malicious activities due to the trusted nature of the gamma.app domain. It filters incoming traffic and checks if there are fewer than 10 links in the body. If any of these links contain the gamma.app domain (either through the root domain or within the query parameters), and specifically if they reference presentation mode (indicated by query parameters containing 'mode=present'), the rule will trigger. This functionality aims to protect users from threats like credential phishing and malware that exploit the Gamma App's presentation capabilities.
