Detects network connections to a known Amatera Stealer C2 IP address where the HTTP Host header is spoofed. This technique is used by the malware to masquerade its C2 traffic, often by using a legitimate-looking or unrelated domain in the Host header, while communicating directly with the malicious IP address.

This rule detects network connections or URL click events to a list of domains known to be associated with phishing or malware distribution. The rule specifically looks for connections to these domains that also contain certain path segments like '/wlc/', '/load/', or '/success/', which are often indicative of malicious activity or payload delivery. It also broadly checks for any URL click events containing these suspicious domains.

This rule detects patterns indicative of an Evilginx-style Adversary-in-the-Middle (AiTM) phishing attack. It specifically looks for HTTP requests to hostnames ending in suspicious top-level domains (TLDs) such as .click, .online, .cloud, or .shop, combined with specific URI paths like /wlc/, /load/, or /success/. These patterns are commonly used by AiTM redirectors to capture credentials and session tokens.
