System Service Discovery
Adversaries may try to get information about registered services. Commands that may obtain information about services using operating system utilities are "sc," "tasklist /svc" using Tasklist, and "net start" using Net, but adversaries may also use other tools as well.
admin@338 actors used the following command following exploitation of a machine with LOWBALL malware to obtain information about services:
APT1 used the commands
|BBSRAT||BBSRAT can query service configuration information. |
Comnie runs the command:
Emissary has the capability to execute the command
Epic uses the
|GeminiDuke||GeminiDuke collects information on programs and services on the victim that are configured to automatically run at startup. |
|GravityRAT||GravityRAT has a feature to list the available services on the system. |
|GreyEnergy||GreyEnergy enumerates all Windows services. |
|Hydraq||Hydraq creates a backdoor through which remote attackers can monitor services.  |
|HyperBro||HyperBro can list all services and their configurations. |
|InvisiMole||InvisiMole can obtain running services on the victim. |
|Ixeshe||Ixeshe can list running services. |
|JPIN||JPIN can list running services. |
|jRAT||jRAT can list local services. |
Ke3chang performs service discovery using
Kwampirs collects a list of running services with the command
OilRig has used
|Poseidon Group||After compromising a victim, Poseidon Group discovers all running services. |
|PoshC2||PoshC2 can enumerate service and service permission information. |
S-Type runs the command
Sykipot may use
|SynAck||SynAck enumerates all running services.  |
|Tasklist||Tasklist can be used to discover services running on a system. |
|TrickBot||TrickBot collects a list of install programs and services on the system’s machine. |
Turla surveys a system upon check-in to discover running services and associated processes using the
|Ursnif||Ursnif has gathered information about running services. |
|Volgmer||Volgmer queries the system to identify existing services. |
|WINERACK||WINERACK can enumerate services. |
|ZLib||ZLib has the ability to discover and manipulate Windows services. |
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities, such as Lateral Movement, based on the information obtained.
Monitor processes and command-line arguments for actions that could be taken to gather system information related to services. Remote access tools with built-in features may interact directly with the Windows API to gather information. Information may also be acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.
