Windows Deleted Registry By A Non Critical Process File Path: endpointEndpointrisk_score:362024-09-30version:4
The following analytic detects the deletion of registry keys by non-critical processes. It leverages Endpoint Detection and Response (EDR) data, focusing on registry deletion events and correlating them with processes not typically associated with system or program files. This activity is significant as it may indicate malware, such as the Double Zero wiper, attempting to evade defenses or cause destructive payload impacts. If confirmed malicious, this behavior could lead to significant system damage, loss of critical configurations, and potential disruption of services.
Windows Terminating Lsass Process: endpointEndpointrisk_score:642024-09-30version:4
The following analytic detects a suspicious process attempting to terminate the Lsass.exe process. It leverages Sysmon EventCode 10 logs to identify processes granted PROCESS_TERMINATE access to Lsass.exe. This activity is significant because Lsass.exe is a critical process responsible for enforcing security policies and handling user credentials. If confirmed malicious, this behavior could indicate an attempt to perform credential dumping, privilege escalation, or evasion of security policies, potentially leading to unauthorized access and persistence within the environment.
Suspicious Process File Path: endpointEndpointrisk_score:352024-11-28version:5
The following analytic identifies processes running from file paths not typically associated with legitimate software. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on specific process paths within the Endpoint data model. This activity is significant because adversaries often use unconventional file paths to execute malicious code without requiring administrative privileges. If confirmed malicious, this behavior could indicate an attempt to bypass security controls, leading to unauthorized software execution, potential system compromise, and further malicious activities within the environment.
Executables Or Script Creation In Suspicious Path: endpointEndpointrisk_score:202024-11-28version:5
The following analytic identifies the creation of executables or scripts in suspicious file paths on Windows systems. It leverages the Endpoint.Filesystem data model to detect files with specific extensions (e.g., .exe, .dll, .ps1) created in uncommon directories (e.g., \windows\fonts\, \users\public\). This activity is significant as adversaries often use these paths to evade detection and maintain persistence. If confirmed malicious, this behavior could allow attackers to execute unauthorized code, escalate privileges, or persist within the environment, posing a significant security threat.
