This rule monitors network traffic logs for HTTP requests directed toward domains identified as potentially malicious (gstatcs.com, webfaset.com, bulder.online). It further filters for events involving common web activity patterns, such as Google Tag Manager references or general HTTP/web traffic, which may indicate command and control communication or beaconing behavior.

This rule monitors DNS and email traffic for domains ending in .shop that fuzzy-match against a predefined watchlist of corporate brand names. This behavior is commonly associated with phishing campaigns, brand impersonation, or typosquatting, where attackers use similar-looking domains to lure users into revealing sensitive information or credentials.

Detects network connections to known command and control (C2) infrastructure, including hardcoded malicious domains, specific C2 IP addresses, and suspicious GitHub access patterns by processes other than standard web browsers, which may indicate malicious ingress tool transfer or C2 communication.

Detects network communication to Firebase infrastructure (.firebaseio.com) initiated by Android devices, which may indicate command-and-control (C2) activity associated with the Mantax Otax malware family. This rule tracks initial connections and should be correlated with specific suspicious domains for higher confidence.

Detects network traffic between internal hosts and a known malicious IP address on port 5556, characteristic of Go_RAT (hVNC) command and control communication. This rule monitors for established TCP connections to identify potential C2 beaconing or active remote management sessions by the GapiUpdate campaign.

Detects network activity associated with Rust-based stealer malware, specifically focusing on connections to a known C2 IP address (31.76.7.137) or HTTP requests directed at static-asset paths (e.g., analytics.gif, pixel.png, content.js) when the destination is an IPv4-literal address. This behavior is indicative of C2 beacons or data exfiltration disguised as legitimate web traffic.

Detects repeated manual HTTP GET requests from many distinct source IPs to a canary token resource. The URI pattern follows a format indicative of a tracked canary token resource, and the threshold of 49 unique source IPs accessing the resource within a prolonged period suggests potential unauthorized reconnaissance or probing activities.
