Detects an exploitation attempt against a known SQL injection vulnerability (CVE-2026-62262) in the Piwigo photo gallery application, specifically targeting the 'pwg.images.filteredSearch.create' method via the 'ratings' parameter. The detection monitors inbound HTTP traffic for common SQL injection patterns like UNION SELECT, SLEEP commands, and boolean-based injection payloads.
Detects installation of new certificate on the system which attackers may use to avoid warnings when connecting to controlled web servers or C2s
Detects files, such as container image layers or extracted binaries, that contain a combination of CARBONATO botnet registry infrastructure artifacts and cryptocurrency wallet application strings. This indicates the presence of a trojanized wallet application originating from the CARBONATO operators' unauthenticated registry infrastructure.
Detects the CARBONATO botnet's XMRig cryptocurrency miner attempting to hide its presence on Linux hosts by masquerading as the systemd-logind binary or by spoofing kernel thread names such as [kworker/u2:0] in process command-line arguments.
Detects the CARBONATO GH0ST Hermes Agent activity of harvesting and storing AI API keys (such as OpenAI, Anthropic, Google Gemini, etc.) as plaintext files within the /root/.hermes/loot/ directory. This is consistent with the agent's behavior of staging credentials for later exfiltration.
Detects persistence mechanisms associated with the CARBONATO botnet. The rule identifies two primary behaviors: the execution of a hidden watchdog binary '/usr/local/bin/.docker-network-monitor' by the cron daemon, and the use of 'chattr +i' to make this watchdog binary immutable, preventing deletion or modification.
This rule detects a multi-tool attack chain involving the Cairn autonomous exploitation engine and the Hermes Agent. It flags the co-occurrence of outbound network traffic to both the DeepSeek API (Cairn engine) and the Anthropic Claude API (Hermes Agent) from the same host within a one-hour window. This behavior is indicative of an automated, AI-driven post-exploitation orchestration campaign.
Experimental CommonSecurityLog template for sensor-reported attempts associated with Cisco advisory cisco-sa-ise-rce-se7bYU57: CVE-2026-20307, CVE-2026-20176 and CVE-2026-20211. Cisco links Snort SIDs 67114, 67115, 67116 and 67130-67132. Configure exact exporter event IDs, sensor vendor/product and confirmed ISE management IPs. A match does not prove successful exploitation or root compromise.
Detects attempts to bypass Vite development server file access restrictions by appending query parameters such as ?raw, ?import&raw, or ?import&url&inline to request paths for sensitive files like .env, cloud credentials, and terraform state files.
Detects the execution of bash commands that contain base64 decoding flags, typically used to obfuscate command-line arguments to evade detection, initiated from a terminal application.
Detects the modification of AI agent configuration files (e.g., mcp.json, config.json) followed shortly by the agent spawning a child process that matches typical Model Context Protocol (MCP) server execution patterns. This behavior may indicate an attacker has modified the configuration to inject malicious server commands or tools that the AI agent will execute upon next initialization, effectively achieving persistent code execution via the agent's legitimate functionality.
This rule monitors Linux system logs for attempts to modify the /etc/sudoers file, utilize sudoers.d configurations, or execute commands with NOPASSWD privileges. These activities are common precursors to privilege escalation or persistence through elevated command execution.
Detects instances where a Claude process accesses a 'SKILL.md' file, followed closely by a suspicious command execution on the same device. The rule specifically targets command-line activity that involves encoding, download-and-execute patterns, staging in sensitive directories, or communication with suspicious domains/IPs, which is indicative of a supply-chain or poisoned agent-skill file attack.
This rule correlates endpoint-based alerts related to credential theft or infostealer malware with subsequent successful cloud identity authentication events. It identifies situations where a user, who has recently triggered a credential theft alert on an endpoint, logs into a cloud environment from a country or IP address that has not been historically associated with that user within a 24-hour window.
This rule detects the execution of common command-line cloud synchronization and file transfer utilities (such as rclone, rsync, and MEGAcmd) when invoked with flags or patterns indicative of data staging or exfiltration, such as copy, sync, or targeting remote cloud storage locations.
Detects a single process reading browser cookie SQLite database files across multiple distinct browser profile directories or different web browsers within a short time window. This behavior is indicative of infostealer activity attempting to harvest session cookies for session hijacking and MFA bypass.
Detects the GitHub Actions runner executing the Bun runtime to run a hidden index.js payload, specifically associated with the compromised 'actions-cool/issues-helper' or 'actions-cool/maintain-one-comment' actions. The rule filters for process execution context tied to GitHub runner internals and validates that the Bun execution follows the pattern observed in these supply chain attacks.
Detects the first-ever observed network connection from a device to WhatsApp Web or Telegram Web within a 30-day lookback period. This behavior is used to identify potentially unauthorized companion-device linking to a user's messenger account, which could indicate credential theft or unauthorized access.
Detects network activity associated with the 'ClickFix' social engineering campaign, which commonly targets users with fake error messages to trick them into executing malicious commands. The rule identifies communication with known malicious infrastructure (domains and IP addresses) found in CommonSecurityLog events, while implementing filters to exclude common security scanners and deduplicating per-host alerts.
