Detects cmd.jar, a JAR-based command executor used by threat actors on compromised Cisco Secure FMC to run arbitrary shell commands via /bin/sh -c
Detects the execution of a reverse shell on Linux systems utilizing a common technique involving mkfifo (named pipe) to redirect input/output for a shell session to a netcat network connection. This is often used by attackers to gain interactive remote access to a compromised host.

Identifies instances of Google Chrome running on endpoints with version numbers below the threshold patched for CVE-2026-85046. This detection focuses on specific build numbers (e.g., 152.0.7977.82 for Windows/Linux) to identify potentially vulnerable browser installations in the environment.
Detects instances where a development-oriented web server (such as Vite or Node.js) is configured to bind to all network interfaces ('0.0.0.0') and is simultaneously receiving inbound connections from non-private, external IP addresses on a common development port (5173). This rule filters out common CI/CD environments to focus on potentially insecure exposure of development tools to the public internet.
Detects attempts to access sensitive files like environment variables (.env), cloud provider credentials (AWS/Azure), or Terraform state files via a web server interface, specifically targeting Vite development server deployments.

This rule detects inbound HTTP requests targeting a Vite development server that attempt to access the '.env' configuration file via the '//@fs/' path, which is a known technique for sensitive file exposure in misconfigured Vite environments.
Detects high-volume bursts of HTTP GET requests against specific paths associated with a Vite development server (/@vite/client, /@fs/, /src/) on port 5173. This pattern is indicative of automated reconnaissance or vulnerability scanning targeting an exposed development environment.
This rule detects attempted exploitation of Adobe Commerce (Magento) via GraphQL, specifically targeting Template Property Poisoning through malicious 'styles' array injection as observed in the StyleSmuggler campaign (CVE-2025-54236).
Detects inbound HTTP POST requests to the /paypal/transparent/response/ endpoint containing encoded PHP webshell payloads, specifically attempting to execute base64-decoded code via eval.
Detects exploitation attempts against the WordPress LiteSpeed Cache plugin (CVE-2024-28000), including suspicious web requests involving ESI/crawler cookie hash manipulation, execution of known exploit binaries (wp28000, wp28000_cp), and subsequent unauthorized creation of administrator accounts via the WordPress REST API.
Detects instances where base64-encoded PHP code, obfuscated behind a 'data:image/gif;base64' MIME type prefix, is written to the disk as a .php file or initiated by web server processes. This pattern is commonly used in file upload bypass attacks to execute arbitrary code.
This rule detects administrative SQL statements (ALTER ROLE, CREATE ROLE, or GRANT) that assign the REPLICATION attribute to a database role. The REPLICATION attribute in PostgreSQL allows a user to initiate streaming replication and perform logical decoding. This is a security-sensitive privilege, as users with this attribute can potentially bypass standard access controls or, if the environment is misconfigured or vulnerable (e.g., CVE-2026-6471), potentially leverage malicious replication plugins to achieve arbitrary code execution.
Detects attempts to modify internal PostgreSQL system catalog tables (pg_authid or pg_proc) to grant superuser privileges or alter authorization records. This activity is commonly associated with exploiting logical decoding plugins to achieve persistence or privilege escalation in PostgreSQL environments.
Detects potential exploitation of PostgreSQL via logical decoding plugins, specifically targeting CVE-2026-6471. The rule monitors for the PostgreSQL server process spawning suspicious shell utilities or loading modules from locations outside of the expected PostgreSQL library or plugin directories, which is a common indicator of unauthorized code execution.
Detects instances of an mcp-grafana server responding with an HTTP 200 status code to a 'tools/call' request without an Authorization header, indicating potential unauthenticated remote tool execution on a vulnerable or misconfigured server.
Detects a single process accessing multiple distinct sensitive files related to cryptocurrency wallets, SSH keys, or seed phrases within a short duration. This pattern of bulk file access is highly indicative of automated credential harvesting modules like those found in the CRPx0 malware family.
This rule detects attempts by users to disable or clear command line history logs for shell environments, including PowerShell (e.g., modifying PSReadLine history) and Unix-like shells (e.g., unset HISTFILE, setting HISTSIZE to 0, or disabling history collection). Such actions are frequently performed by adversaries to hinder incident response and forensic analysis by obscuring their post-exploitation activity.
Detects the disabling of host-based firewalls (Windows Filtering Platform/Advanced Firewall, iptables, or nftables) via command-line tools. The rule excludes common management tools, system accounts, and events where the firewall is re-enabled within a short timeframe, effectively filtering for potentially unauthorized attempts to impair security defenses.
