The following analytic identifies the use of Ldifde.exe, a command-line utility for creating, modifying, or deleting LDAP directory objects. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution and command-line arguments. Monitoring Ldifde.exe is significant because it can be used by attackers to manipulate directory objects, potentially leading to unauthorized changes or data exfiltration. If confirmed malicious, this activity could allow an attacker to gain control over directory services, escalate privileges, or access sensitive information within the network.
The following analytic detects the execution of msiexec.exe with the /y switch parameter, which enables the loading of DLLRegisterServer. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process command-line arguments and parent-child process relationships. This activity is significant because it can indicate an attempt to register malicious DLLs, potentially leading to code execution or persistence on the system. If confirmed malicious, this could allow an attacker to execute arbitrary code, escalate privileges, or maintain persistence within the environment.
The following analytic identifies the execution of Odbcconf.exe within the environment. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process creation events where the process name is Odbcconf.exe. This activity is significant because Odbcconf.exe can be used by attackers to execute arbitrary commands or load malicious DLLs, potentially leading to code execution or persistence. If confirmed malicious, this behavior could allow an attacker to maintain access to the system, execute further malicious activities, or escalate privileges, posing a significant threat to the environment.
The following analytic detects the execution of odbcconf.exe with the regsvr action to load a DLL. This is identified by monitoring command-line arguments in process creation logs from Endpoint Detection and Response (EDR) agents. This activity is significant as it may indicate an attempt to execute arbitrary code via DLL loading, a common technique used in various attack vectors. If confirmed malicious, this could allow an attacker to execute code with the privileges of the odbcconf.exe process, potentially leading to system compromise or further lateral movement.
The following analytic detects the execution of odbcconf.exe with a response file, which may contain commands to load a DLL (REGSVR) or other instructions. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. This activity is significant as it may indicate an attempt to execute arbitrary code or load malicious DLLs, potentially leading to unauthorized actions. If confirmed malicious, this could allow an attacker to gain code execution, escalate privileges, or establish persistence within the environment.
This detection identifies potentially suspicious usage of sqlcmd.exe, focusing on command patterns that may indicate data exfiltration, reconnaissance, or malicious database operations. The detection looks for both short-form (-X) and long-form (--flag) suspicious parameter combinations, which have been observed in APT campaigns targeting high-value organizations. For example, threat actors like CL-STA-0048 have been known to abuse sqlcmd.exe for data theft and exfiltration from compromised MSSQL servers. The detection monitors for suspicious authentication attempts, output redirection, and potentially malicious query patterns that could indicate unauthorized database access or data theft.
The following analytic detects the use of the PowerShell cmdlet 'export-certificate' executed via the command line, indicating an attempt to export a certificate from the local Windows Certificate Store. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs and command-line arguments. Exporting certificates is significant as it may indicate credential theft or preparation for man-in-the-middle attacks. If confirmed malicious, this activity could allow an attacker to impersonate users, decrypt sensitive communications, or gain unauthorized access to systems and data.
The following analytic detects the execution of the SubInAcl utility. SubInAcl is a legacy Windows Resource Kit tool from the Windows 2003 era, used to manipulate security descriptors of securable objects. It leverages data from Endpoint Detection and Response (EDR) agents, specifically searching for any process execution involving "SubInAcl.exe" binary. This activity can be significant because the utility should be rarely found on modern Windows machines, which mean any execution could potentially be considered suspicious. If confirmed malicious, this could allow an attacker to blind defenses by tampering with EventLog ACLs or modifying the access to a previously denied resource.
The following analytic detects `wmic.exe` loading a remote XSL script
via a URL. This detection leverages Endpoint Detection and Response (EDR) data,
focusing on command-line executions that include HTTP/HTTPS URLs and the /FORMAT
switch. This activity is significant as it indicates a potential application control
bypass, allowing adversaries to execute JScript or VBScript within an XSL file.
If confirmed malicious, this technique can enable attackers to execute arbitrary
code, escalate privileges, or maintain persistence using a trusted Windows tool,
posing a severe threat to the environment.

The following analytic detects the execution of an XSL script using the WMIC process, which is often indicative of malicious activity. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions involving WMIC and XSL files. This behavior is significant as it has been associated with the FIN7 group, known for using this technique to execute malicious scripts. If confirmed malicious, this activity could allow attackers to execute arbitrary code, potentially leading to system compromise and further malicious actions within the environment.
Detects the ClickFix/fake-CAPTCHA initial access pattern where users are socially engineered into copying and pasting malicious commands into the Windows Run dialog or a browser-spawned shell. The rule matches on process creation events involving mshta.exe, powershell.exe, or wscript.exe initiated by explorer.exe or common shell-related processes, filtering out known administrative and deployment software.
Detects a suspected ClickFix social engineering attack where a user is tricked into pasting malicious commands into Windows Terminal, leading to a PowerShell download, followed by the appearance of specific known malicious artifacts (LockScreenContentServer.exe, dui70.dll, or 1.bat) within 15 minutes on the same device.
This rule monitors endpoint telemetry for indicators of compromise (IOCs) associated with known malicious activity. It checks for file creation, process execution, and network connections that match a defined list of malicious file hashes (SHA256, SHA1, MD5), C2 IP addresses, and malicious domains or URL patterns.
Detects the OIC-lure Mustang Panda PlugX infection chain with tightened false-positive controls: requires the console-resize artifact (mode.com with digit,digit args) that precedes the download, requires PowerShell to be parented directly by explorer.exe (filtering out legitimate scheduled-task/management-agent automation that also chains curl+tar), requires curl to combine -L with -k/-s (insecure/silent) flags, narrows all correlation windows to 2 minutes, and excludes shell/utility processes from the final execution match.

The following analytic detects the execution of a DCRat "forkbomb" payload, which spawns multiple cmd.exe processes that launch notepad.exe instances in quick succession. This detection leverages Endpoint Detection and Response (EDR) data, focusing on the rapid creation of cmd.exe and notepad.exe processes within a 30-second window. This activity is significant as it indicates a potential DCRat infection, a known Remote Access Trojan (RAT) with destructive capabilities. If confirmed malicious, this behavior could lead to system instability, resource exhaustion, and potential disruption of services.
The following analytic detects potentially malicious processes that initiate a ping delay using an invalid IP address.
It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions involving "ping 0 -n".
Malware like NJRAT was observed using this technique to introduce time delays for evasion tactics, such as delaying self-deletion.
If confirmed malicious, this activity could indicate an active infection attempting to evade detection, potentially leading to further compromise and persistence within the environment.
