This rule detects attempts to access typosquatted domains commonly used in phishing attacks. It specifically looks for HTTP requests where the host header contains variations of popular brand names like 'microsoft', 'google', 'paypal', 'amazon', and 'linkedin' with common typos (e.g., 'micros0ft', 'g00gle', 'paypa1', 'arnazon', 'linkedln'). The rule triggers on established HTTP connections to the server.
