Detects potential exploitation of a critical ABAP code injection vulnerability (CVE-2025-42957) in SAP S/4HANA. An attacker with low-level privileges can leverage a vulnerable RFC module, /SLOAE/DEPLOY, to execute arbitrary code and gain full control of the system.
Detects potential misuse of AI model APIs by correlating process creation, network activity, and non-standard AI service ports.
Covers Ollama, OpenAI, Azure OpenAI, Anthropic, Google Gemini, Mistral, Cohere, Copilot, OpenRouter, Together, and Perplexity.

Detects activity related to the PromptLock ransomware, which leverages the Ollama AI API and is written in Go. This rule looks for network connections to the Ollama service (port 11434) and related process executions, specifically identifying processes like go.exe, curl.exe, wget.exe, python.exe, powershell.exe making connections or processes with 'ollama' in their command line.
This detection identifies suspicious child processes of SpeechRuntime.exe that could indicate abuse of a vulnerability. SpeechRuntime is vulnerable to an attack that allows a user to run code on another user's session remotely and stealthily by exploiting a Windows COM class. When this class is invoked, it launches SpeechRuntime.exe in the context of the currently logged-on user. Because this COM class is susceptible to COM Hijacking, an attacker can alter the registry remotely to point to a malicious DLL. By dropping that DLL on the target system (e.g., via SMB) and triggering the COM object, the attacker causes the malicious DLL to load into SpeechRuntime.exe and execute under the user's context. The rule specifically looks for SpeechRuntime.exe spawning common command and scripting interpreters or tools used for execution and file transfer.
No description available.
Detects the execution of the 'forfiles.exe' utility with the '/c' flag. This behavior, while legitimate, can be abused by adversaries to proxy execution of arbitrary commands or binaries, potentially bypassing application whitelisting controls. This technique is often associated with Living Off The Land Binaries (LOLBAS).
Detects a potentially suspicious one-liner command combining 'ping' and 'copy' within a 'cmd.exe' process. This combination is often used by malware for purposes such as network reconnaissance followed by data staging or exfiltration, or as a defense evasion technique by leveraging common system utilities in an unusual manner. The rule specifically looks for the presence of 'ping' and 'copy ' along with either the '-n' (count) or '-y' (yes to overwrite) flags in the command line.
This rule detects the use of PsExec or PAExec with command-line flags designed to escalate privileges to the LOCAL_SYSTEM account. Specifically, it looks for the '-s' flag, optionally combined with '-i', followed by common shell executables like 'cmd', 'powershell', or 'pwsh'. This behavior is indicative of an attempt to gain SYSTEM-level access on a Windows machine.
Detects various techniques, procedures, and indicators associated with the RustyPages macOS malware dropper, including persistence, defense evasion, payload download, and known IOCs. This rule specifically looks for the use of `curl` to download a hidden file, `launchctl` to establish persistence, `chmod` to make the payload executable, `xattr` to clear extended attributes, `pgrep` to discover security tools, shell commands to silence notifications, C2 domain/IP connections, and known malware file hashes.
Detects the expansion or decompression of cabinet files using 'expand.exe' from potentially suspicious or uncommon locations. This activity has been observed in attacks such as those related to Iranian MeteorExpress and Konni malware.
Detects TOSHIS malware, a loader used in the TAOTH campaign to deploy Cobalt Strike or Merlin Agent. This rule identifies the malware based on unique strings found in the payload.
Detects the execution of 'ftp.exe' with the '-s' or '/s' flag, which indicates script execution, or any child processes spawned by 'ftp.exe'. This behavior can be abused by adversaries for arbitrary command execution, often as a method of defense evasion or indirect command execution.
Detects the execution of 'lodctr.exe' with the '-r' flag, which is used to rebuild performance counter registry values. Attackers can abuse this utility by providing a malicious configuration file to overwrite performance counter configurations, potentially confusing or evading monitoring and security solutions.
This rule detects commands executed via the Run dialog (Win+R), which is often used by attackers or malicious scripts to launch tools like PowerShell, cmd, or other malicious payloads. It specifically looks for modifications to the 'RunMRU' registry key by 'explorer.exe' that contain suspicious keywords or patterns indicative of command execution, especially in scenarios like ClickFix-style attacks where users are tricked into running commands.
This KQL rule detects commands executed via the Run dialog by monitoring changes to the "Runmru" registry key. This key stores a history of commands entered into the Run dialog. Attackers or malicious scripts often use this method to launch tools like PowerShell, cmd, or malicious payloads, particularly in social engineering attacks where users are tricked into running commands.
This rule detects suspicious command-line activity, specifically file downloads using 'curl' initiated by a web browser. This behavior may indicate malicious JavaScript or HTML triggering command execution, a user being tricked into clicking a link that launches a command, or initial access/payload download in a phishing or drive-by attack.
Detects the PHP variant of the CORNFLAKE.V3 backdoor, which is often dropped as 'config.cfg' and used for C2 communications and payload execution.
This rule detects activities associated with the RomCom threat group, including exploitation of CVE-2025-8088 (WinRAR path traversal), COM hijacking for persistence, anti-analysis techniques (RecentDocs check), C2 communication, and suspicious WMIC execution, potentially linked to a Mythic agent.
This rule detects activities associated with the Charon ransomware, including DLL side-loading, process creation patterns, file modifications related to ransom notes and payload artifacts, shadow copy deletion attempts, and service creation for persistence. It also includes SHA1 hashes for known Charon ransomware executables.
Detects the execution of "forfiles" with the "/c" flag.
While this is an expected behavior of the tool, it can be abused in order to proxy execution through it with any binary.
Can be used to bypass application whitelisting.

Detects unusual domain resolutions originating from CScript/WScript that can identify malicious javascript files executing in an environment, often as a result from a phishing or watering hole attack.
