Windows Service Abuse

• First Time Seen Running Windows Service :
  endpoint Endpoint risk_score:25 2024-10-17 version:6
  The following analytic detects the first occurrence of a Windows service running in your environment. It leverages Windows system event logs, specifically EventCode 7036, to identify services entering the "running" state. This activity is significant because the appearance of a new or previously unseen service could indicate the installation of unauthorized or malicious software. If confirmed malicious, this activity could allow an attacker to execute arbitrary code, maintain persistence, or escalate privileges within the environment. Monitoring for new services helps in early detection of potential threats.


• Reg exe Manipulating Windows Services Registry Keys :

  The following analytic detects the use of reg.exe to modify registry keys associated with Windows services and their configurations. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names, parent processes, and command-line executions. This activity is significant because unauthorized changes to service registry keys can indicate an attempt to establish persistence or escalate privileges. If confirmed malicious, this could allow an attacker to control service behavior, potentially leading to unauthorized code execution or system compromise.


• Sc exe Manipulating Windows Services :

  The following analytic detects the creation or modification of Windows services using the sc.exe command. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. This activity is significant because manipulating Windows services can be a method for attackers to establish persistence, escalate privileges, or execute arbitrary code. If confirmed malicious, this behavior could allow an attacker to maintain long-term access, disrupt services, or gain control over critical system functions, posing a severe threat to the environment.
