The following analytic identifies attempts to stop services on a system using `net.exe`, `sc.exe` or the "Stop-Service" cmdlet. It leverages Endpoint Detection and Response (EDR) telemetry. This activity can be significant as adversaries often terminate security or critical services to evade detection and further their objectives. If confirmed malicious, this behavior could allow attackers to disable security defenses, facilitate ransomware encryption, or disrupt essential services, leading to potential data loss or system compromise.
The following analytic detects the execution of the Windows built-in tool netsh.exe to display the state, configuration, and profile of the host firewall. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions and process metadata. Monitoring this activity is crucial as netsh.exe can be used by adversaries to bypass firewall rules or discover firewall settings. If confirmed malicious, this activity could allow attackers to manipulate firewall configurations, potentially leading to unauthorized network access or data exfiltration.
The following analytic detects the execution of the `route.exe` Windows application, commonly used for network discovery. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process creation events. This activity is significant because adversaries often use `route.exe` to map network routes and identify potential targets within a network. If confirmed malicious, this behavior could allow attackers to gain insights into network topology, facilitating lateral movement and further exploitation. Note that false positives may occur due to legitimate administrative tasks or automated scripts.
The following analytic detects the execution of the Windows OS tool quser.exe, commonly used to gather information about user sessions on a Remote Desktop Session Host server. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs. Monitoring this activity is crucial as quser.exe is often abused by post-exploitation tools like winpeas, used in ransomware attacks to enumerate user sessions. If confirmed malicious, attackers could leverage this information to further compromise the system, maintain persistence, or escalate privileges.
The following analytic detects the execution of wbadmin.exe with flags that delete backup files, specifically targeting catalog or system state backups. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. This activity is significant because it is commonly used by ransomware to prevent recovery by deleting system backups. If confirmed malicious, this action could severely hinder recovery efforts, leading to prolonged downtime and potential data loss.
