Detects Windows error reporting events where the process that crashed is LSASS (Local Security Authority Subsystem Service).
This could be the cause of a provoked crash by techniques such as Lsass-Shtinkering to dump credentials.
This could be the cause of a provoked crash by techniques such as Lsass-Shtinkering to dump credentials.
Detects the crash of lsass.exe caused by WLDAP32.dll, which is a strong indicator of exploitation of the LDAPNightmare vulnerability (CVE-2024-49113). This exploit causes a denial of service on unpatched Windows Servers.
Detects Ollama server errors and failures during model loading operations that may indicate malicious model injection, path traversal attempts, or exploitation of model loading mechanisms to achieve remote code execution. Adversaries may attempt to load specially crafted malicious models or exploit vulnerabilities in the model loading process to execute arbitrary code on the server. This detection monitors error messages and failure patterns that could signal attempts to abuse model loading functionality for malicious purposes.
Detects critical service crashes, fatal errors, and abnormal process terminations in Ollama that may indicate exploitation attempts, resource exhaustion attacks, malicious input triggering unhandled exceptions, or deliberate denial of service attacks designed to disrupt AI model availability and degrade system stability. The rule aggregates multiple termination events within a 5-minute window to identify sustained instability or attack patterns.
This rule detects when critical Windows services or processes associated with Active Directory (NTDS, Netlogon, LSASS, LDAP) or the Print Spooler (Spooler, spoolsv.exe) crash multiple times (3 or more) on a machine within a 7-day period. This could indicate instability, a denial-of-service attempt, or a system compromise affecting core services.
Detects potential exploitation of Dell ControlVault vulnerabilities (dubbed 'ReVault') by monitoring for related service crashes or the abnormal loading of the `bcmbipdll.dll` module. An attacker with local access can exploit these vulnerabilities for privilege escalation or persistence.
This query identifies crashing processes based on parameters passed
to werfault.exe and attempts to find the associated process launch
from DeviceProcessEvents.

Detects "BugCheck" errors indicating the system rebooted due to a crash, capturing the bugcheck code, dump file path, and report ID.
Detects exploitation attempts of CVE-2024-49113, known as LDAP Nightmare. This rule specifically looks for "Application Error" events (EventID 1000) where the faulting application is "lsass.exe" and the faulting module is "WLDAP32.dll". This combination indicates a crash in the Local Security Authority Subsystem Service (LSASS) related to the Windows Lightweight Directory Access Protocol (LDAP) client library, which is consistent with the described vulnerability exploitation.
This rule detects when an Nginx worker process crashes and generates a core dump, indicated by the log message 'exited on signal 6 (core dumped)'. This event can signify a serious underlying problem with the Nginx configuration, a plugin, or potentially an exploitation attempt targeting the Nginx server. Core dumps contain the memory state of the process at the time of the crash, which can be valuable for debugging but also sensitive if exposed.
This rule detects a suspicious crash of the Microsoft Malware Protection Engine (MsMpEng.exe) as indicated by an Application Error event (EventID 1000) containing both 'MsMpEng.exe' and 'mpengine.dll' in the event data. Such crashes could be indicative of an attempt to bypass or disable antivirus defenses, potentially through exploitation of vulnerabilities in the engine.
This rule detects a suspicious crash of the Microsoft Malware Protection Engine (MsMpEng.exe), specifically when the mpengine.dll module is involved. Such crashes can indicate an attempt to exploit vulnerabilities in the antivirus software to bypass security defenses or disable the tool. The detection relies on Windows Error Reporting (EventID 1001) logs containing specific process and module names.
Detects Windows error reporting events where the Local Security Authority Subsystem Service (LSASS) process crashes with a specific exception code. This behavior can indicate an intentional crash, often associated with techniques like Lsass-Shtinkering, to facilitate credential dumping from LSASS memory.
This rule detects a 'Segmentation Fault' error message in Apache error logs, indicating a crashing Apache worker process. This type of event can be caused by software vulnerabilities, misconfigurations, or malicious activity aiming to disrupt service availability.
Detects a crash of the "WinRAR.exe" application with a version lower than 6.23, which could indicate an attempted exploitation of CVE-2023-40477. The rule specifically looks for Application Error events (EventID 1000) where the provider is 'Application Error' and the crashing application is 'WinRAR.exe', excluding versions 6.23 and higher.
This rule detects when the Sysmon service crashes, indicated by an 'Application Popup' event with EventID 26 and a caption explicitly mentioning 'sysmon.exe - Application Error' or 'sysmon64.exe - Application Error'. This could signify an attempt to impair or disable Sysmon, which is a critical defense mechanism for endpoint monitoring.
Nginx Core Dump
Sigma
Detects a core dump of a crashing Nginx worker process, which could be a signal of a serious problem or exploitation attempts.
