Detects HTTP beaconing and command-and-control (C2) communication patterns consistent with the 'Corp_MDM' Android spyware, specifically heartbeat check-ins, command polling, and result reporting to a known malicious C2 IP address.

Detects anomalous C2 traffic associated with SectopRAT that leverages JSON-RPC 'eth_call' methods on 'binance.org'. The detection monitors for a specific POST request pattern followed by a response containing 'START' and 'FINISH' markers within the result field, indicating command-and-control communication disguised as blockchain interactions.

Detects network activity (DNS queries, TLS SNI, and HTTP requests) associated with identified 'ShipmentsFree' scam domains. These domains are typically used in phishing or credential harvesting campaigns to trick users into visiting fake account or tracking pages.

This rule identifies DNS queries or web requests directed toward a known list of domain names associated with the 'ShipmentsFree' family of shipping-rebate scams. These scams are typically designed to lure consumers into unknowingly signing up for recurring, undisclosed subscription services.

This rule detects network communication (DNS queries and TLS connections) to known actor-controlled Slack workspace subdomains, as well as the presence of a specific hardcoded public key in Slack API traffic, suggesting the use of Slack as a Command and Control (C2) channel.
Detects HTTP GET requests to external services 'trycloudflare.com' or 'workers.dev' that return a file content starting with the 'MZ' and 'PE' header signatures within the first 256 bytes, indicating a Windows executable payload download often associated with AvisLoader activity.

Detects outbound HTTP requests to identified scam infrastructure (e.g., herokuapp domains) containing platform-specific query parameters (win or mac). This behavior is indicative of a user interacting with a malicious site that is delivering an OS-tailored locker or malware payload.
Detects high-frequency anonymous comment submissions to 'wp-comments-post.php' from a single IP address within a 10-minute window, characterized by minimal variations in User-Agent. This behavior is indicative of an automated script attempting to bypass comment moderation settings, potentially exploiting known vulnerabilities (e.g., CVE-2026-93485) to inject content without administrative approval.

This behavior is indicative of an automated script attempting to bypass comment moderation settings, potentially exploiting known vulnerabilities (e.g., CVE-2026-93485) to inject content without administrative approval.
Detects anomalous, high-frequency requests from a single source IP targeting sensitive NetScaler/Citrix ADC Gateway paths. This behavior is indicative of automated reconnaissance or vulnerability scanning often preceding exploitation attempts.
Detects HTTP PUT requests that follow a specific pattern associated with MacSync Stealer's exfiltration mechanism. The rule identifies multipart data transmission by looking for specific URI parameters ('upload_id', 'chunk_index', 'total_chunks') used to piece together stolen ZIP files over an established HTTP connection.
Detects an unauthenticated remote code execution (RCE) attempt against Langflow via the /api/v1/validate/code endpoint. The rule monitors for POST requests containing code execution patterns such as eval, exec, os.system, or subprocess, indicating an attacker attempting to leverage the vulnerability to execute arbitrary commands.
This rule monitors for network traffic directed to 'gitnow.dev' using TLS SNI or HTTP headers consistent with WebSocket upgrades. This domain is associated with 'ClickFix' social engineering campaigns where attackers instruct users to copy and paste malicious code into a terminal to establish a reverse-tunnel C2 connection.
Detects HTTP traffic originating from curl user agents attempting to communicate with known MacSync Stealer command-and-control URI patterns, specifically targeting GET check-in requests and POST payload exfiltration requests.
