Detects network activity associated with the 'ClickFix' campaign, specifically targeting the cdnsuicaches[.]com domain. The rules identify the initial DNS query, the subsequent TLS SNI connection, and the retrieval of malicious JavaScript containing the 'cookie-captcha-complete' overlay signature. This behavior is indicative of a browser-based social engineering attack.

Detects Sauron Loader C2 registration/polling: an HTTPS POST whose URI path matches the malware's exact <prefix>/v<1-9>/<action><Resource> structure (action = set|get; resource = one of the 10 known config/task resource names) combined with the malware's hardcoded Windows-10 Edge/Chrome 143 user agent. Narrowing the URI regex from a generic '/api/v1/anything' wildcard to the exact action+resource vocabulary eliminates matches against ordinary versioned REST API traffic, which was the dominant false-positive source.
