Detects evidence of post-exploitation anti-forensic activity on Cisco SD-WAN components (vManage, vSmart, vBond). This rule monitors for unauthorized removal of logs and exploitation artifacts, the clearing of shell command history, and suspicious modification of file and directory permissions on critical system paths.
This rule detects a scenario where an AI agent (Python or Node.js based) reads a corporate document (PDF, DOCX, TXT, MD) and subsequently spawns a command shell (cmd.exe, powershell.exe, sh, bash) within a 30-second window. This behavior indicates a potential indirect Remote Code Execution (RCE) where a prompt-injected payload from a poisoned document was executed by the AI agent.
Detects bash or sh executing a fanout script from a temporary directory. This behavior is often associated with lateral movement or propagation activities by adversaries.
Detects attackers creating transient systemd units via systemd-run to persist malware or
reverse shells outside normal unit files. Linux malware families including cryptominers and
botnets use --remain-after-exit and custom unit names under /tmp or /dev/shm to survive
logout while evading static service file inspection.

logout while evading static service file inspection.
Detects the execution of commands that parse the /etc/hosts file for PeopleSoft-related node names (WEB, APP, csprd). This activity is indicative of an adversary attempting to discover internal application and web servers, potentially for lateral movement. Threat actors like ShinyHunters have used this technique.

Detects Jellyfin's automated ffprobe media scan pipeline spawning suspicious network-related shell commands. This indicates active exploitation of the PixelSmash vulnerability (CVE-2026-8461) via zero-click library scans.
Detects Jellyfin's automated ffprobe media scan pipeline spawning suspicious network-related shell commands. This indicates active exploitation of the PixelSmash vulnerability (CVE-2026-8461) via zero-click library scans.
Detects instances where FFmpeg media processing tools spawn interactive shell processes. This behavior is highly indicative of successful remote code execution (RCE) via CVE-2026-8461 (PixelSmash), where an attacker hijacks the AVBuffer struct to call libc's system() function.
Detects network traffic over port 6757, which is indicative of PureHVNC command and control (C2) communication.
This rule detects the creation, execution, or presence of specific file names and command-line arguments associated with local RCE research, proof-of-concept exploits, and server-side harnesses, specifically identifying artifacts prefixed with 'libpwn_'.
Detects the creation or execution of files associated with the Floci remote code execution (RCE) proof-of-concept tool. It monitors for specific filenames or command-line patterns indicative of this exploit, particularly when spawned from Java-based applications or involving shell command execution.
This rule detects a POST request to the MyBB administrative interface (specifically the user-users module) that contains parameters indicating an attempt to escalate a limited administrative user to a full administrator by assigning the 'usergroup=4' or 'gid=4' identifier, which corresponds to the default Administrator group in MyBB.
Detects anomalous process execution patterns associated with the Gitea Act Runner that indicate attempts to break out of container isolation. This includes the use of sensitive Docker flags like --privileged, --pid=host, or --ipc=host, the mounting of the Docker daemon socket, or the execution of nsenter to gain access to the host namespace, which are indicative of container escape techniques.
Detects potential HTTP Request Smuggling attempts targeting nghttpx proxies. The rule monitors for malicious request patterns involving HTTP/1.1 Upgrade headers combined with a body (Content-Length) designed to poison the request queue, as well as specific path patterns (e.g., /upgrade, /poisoned) or server-agent identification of the nghttp2/nghttpx service.
Detects Node.js or JavaScript runtimes executing code patterns commonly associated with GlassWorm-style supply chain attacks. The campaign abuses invisible Unicode variation selectors to hide malicious payloads that are decoded and executed through eval(). Investigate execution originating from repositories, package managers, VS Code extensions, or temporary development directories.
Detects potential privilege escalation within the MyBB Administrative Control Panel (ACP). The rule identifies POST requests to user management modules that set a user's group ID (gid) or usergroup to 4, which typically corresponds to the administrator group in MyBB. It verifies the escalation by correlating it with a prior session that lacked administrator privileges and identifying a subsequent login event.
Detects unauthorized attempts to escalate privileges within the MyBB Admin Control Panel (ACP) by creating a new account or modifying an existing one to belong to the administrator group (gid=4). This is indicative of an attacker attempting to gain full administrative control by bypassing module-level access restrictions.
This rule detects network connections from internal hosts to identified C2 or phishing infrastructure associated with the threat actor group UNC1151 (also known as Ghostwriter). It monitors both host-based network events (via DeviceNetworkEvents) and centralized network security logs (via CommonSecurityLog) for traffic targeting a curated list of known malicious IP addresses.

Detects potential credential theft activity where a user or compromised process executes shell commands to inspect environment variables, AWS credential files, or project configuration files (e.g., .env) for sensitive secrets such as API keys and access tokens.
