This detection rule identifies potential open redirect vulnerabilities specifically involving the domain 'predictiveresponse.net'. Open redirects occur when a website allows users to be redirected to external URLs without proper validation, which can be exploited for phishing attacks and malware distribution. The rule analyzes inbound messages for links referencing 'predictiveresponse.net' that include a query parameter containing 'redirect='. It checks that these redirects do not directly point back to 'predictiveresponse.net', indicating an intended misuse of that infrastructure. Additionally, it ensures that the sender's domain does not match 'predictiveresponse.net', and negates trusted sender domains unless they failed DMARC authentication, refining the detection of potentially malicious activity. By leveraging sender and URL analysis, the rule aims to prevent credential phishing and malware attacks facilitated by open redirect mechanisms.
