Scheduling a task on a remote system typically required being a member of the Administrators group on the the remote system. (Citation: TechNet Task Scheduler Security)\n\nAn adversary may use task scheduling to execute programs at system startup or on a scheduled basis for persistence, to conduct remote Execution as part of Lateral Movement, to gain SYSTEM privileges, or to run a process under the context of a specified account.\n\nDetection: Monitor scheduled task creation from common utilities using command-line invocation. Legitimate scheduled tasks may be created during installation of new software or through system administration functions. Monitor process execution from the <code>svchost.exe<\/code> in Windows 10 and the Windows Task Scheduler <code>taskeng.exe<\/code> for older versions of Windows. (Citation: Twitter Leoloobeek Scheduled Task) If scheduled tasks are not used for persistence, then the adversary is likely to remove the task when the action is complete. Monitor Windows Task Scheduler stores in <code>%systemroot%\\System32\\Tasks<\/code> for change entries related to scheduled tasks that do not correlate with known software, patch cycles, etc. 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 network connections made for Command and Control, learning details about the environment through Discovery, and Lateral Movement.\n\nConfigure event logging for scheduled task creation and changes by enabling the \"Microsoft-Windows-TaskScheduler\/Operational\" setting within the event logging service. (Citation: TechNet Forum Scheduled Task Operational Setting) Several events will then be logged on scheduled task activity, including: (Citation: TechNet Scheduled Task Events)\n\n*Event ID 106 - Scheduled task registered\n*Event ID 140 - Scheduled task updated\n*Event ID 141 - Scheduled task removed\n\nTools such as Sysinternals Autoruns may also be used to detect system changes that could be attempts at persistence, including listing current scheduled tasks. (Citation: TechNet Autoruns) Look for changes to tasks that do not correlate with known software, patch cycles, etc. Suspicious program execution through scheduled tasks may show up as outlier processes that have not been seen before when compared against historical data.\n\nMonitor processes and command-line arguments for actions that could be taken to create tasks. Remote access tools with built-in features may interact directly with the Windows API to perform these functions outside of typical system utilities. Tasks may also be created through Windows system management tools such as Windows Management Instrumentation and PowerShell, so additional logging may need to be configured to gather the appropriate data.\n\nPlatforms: Windows\n\nData Sources: File monitoring, Process command-line parameters, Process monitoring, Windows event logs\n\nEffective Permissions: Administrator, SYSTEM, User\n\nPermissions Required: Administrator, SYSTEM, User\n\nRemote Support: Yes\n\nContributors: Travis Smith, Tripwire, Leo Loobeek, @leoloobeek, Alain Homewood, Insomnia Security", |

schtasks commands
Schedules commands and programs to run periodically or at a specific time, adds and removes tasks from the schedule, starts and stops tasks on demand, and displays and changes scheduled tasks.
[!NOTE] The schtasks.exe tool performs the same operations as Scheduled Tasks in Control Panel. You can use these tools together and interchangeably.
Required permissions
-
To schedule, view, and change all tasks on the local computer, you must be a member of the Administrators group.
-
To schedule, view, and change all tasks on the remote computer, you must be a member of the Administrators group on the remote computer, or you must use the /u parameter to provide the credentials of an Administrator of the remote computer.
-
You can use the /u parameter in a /create or /change operation if the local and remote computers are in the same domain, or if the local computer is in a domain that the remote computer domain trusts. Otherwise, the remote computer can’t authenticate the user account specified, and it can’t verify that the account is a member of the Administrators group.
-
The task you plan to run must have the appropriate permission; these permissions vary by task. By default, tasks run with the permissions of the current user of the local computer, or with the permissions of the user specified by the /u parameter, if one is included. To run a task with permissions of a different user account or with system permissions, use the /ru parameter.
