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 successful network connections to a known hVNC RAT (GapiUpdate) C2 infrastructure IP address on port 5556, based on DeviceNetworkEvents logs.
Detects unauthorized access and data retrieval attempts from a MinIO object storage instance using default administration credentials (minioadmin:minioadmin). The rule monitors both command-line execution of MinIO client (mc) operations and network connections to MinIO service ports (9000/9001) that involve the use of the default credential pair.

The rule monitors both command-line execution of MinIO client (mc) operations and network connections to MinIO service ports (9000/9001) that involve the use of the default credential pair.
This rule monitors for various types of events (user logons, network connections, API audits, cloud app events, and email traffic) originating from a specific CIDR block (160.79.104.0/21), which is flagged as suspicious or unauthorized.
This rule correlates email sender activity with network, cloud, and identity logs by matching traffic against a specific IP range (160.79.104.0/21) identified as malicious or suspicious. The rule flags instances where this range appears as an email sender IP or as a remote/source IP address across various infrastructure indices, potentially indicating adversary communication or exfiltration.

This rule detects various event types (email, identity authentication, network connections, and cloud audit logs) originating from or interacting with the specific IP address range 160.79.104.0/22 to 160.79.111.0/22, which is associated with known malicious activity.

This rule detects DNS queries for domains associated with potential Command and Control (C2) activity, specifically 'service-nowinc.com' and 'domainlify.net'. These domains are flagged as suspicious, and their presence in DNS logs suggests potential malicious intent or communication with adversary infrastructure.
Detects activity associated with the 'MovieReaper' threat campaign by identifying known malicious file hashes, command and control (C2) IP addresses, and communication with identified malicious domains. This rule monitors process execution, file operations, and network connections within the campaign's active timeframe.
Detects anomalous TCP stream reassembly where overlapping segments contain different data. This technique is often used to bypass Network Intrusion Detection Systems (IDS) by presenting different data to the target system than what the IDS inspects.
This rule monitors network traffic and internal logs for connections to known malicious IP addresses or domain names associated with 'ClickFix' social engineering campaigns (often impersonating services like HBO Max). The logic explicitly filters out known threat intelligence scanners and security researcher probes. It performs correlation by requiring domain/message matches for generic IP-based alerts to reduce noise, and aggregates events per host over 15-minute windows to produce consolidated alerts.
Detects network traffic matching a list of known malicious domains and IP addresses observed in CommonSecurityLog events, tightened to reduce noise from scanners/TI feeds, sinkholed infrastructure, and generic reused IPs by requiring domain-specific selectors and deduplicating repeated matches per host.

Detects network requests to the Gitea Prometheus metrics API that contain 'k=' and 'x=' query parameters, a pattern indicative of a C2 command channel disguised as legitimate telemetry traffic.
