This detection rule identifies potential open redirect vulnerabilities related to the domain 'easycamp.com'. Open redirects can lead to various malicious activities including phishing and the spread of malware/ransomware. The rule analyzes incoming messages to check if they contain links redirecting to 'easycamp.com' and whether these links have specific redirect query parameters without being securely redirected to the same domain. It also incorporates checks on the sender's domain reputation, ensuring messages from high-trust domains are properly authenticated via DMARC. The rule ensures that unsolicited messages or those marked as malicious are also flagged for review. This is crucial as attackers often leverage open redirects to trick users into visiting harmful sites while appearing to come from a trusted source.
