T1053.005: Scheduled Task
Adversaries may abuse the Windows Task Scheduler to perform task scheduling for initial or recurring execution of malicious code. There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel.[1] In some cases, adversaries have used a .NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.[2]
An adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence. The Windows Task Scheduler can also be abused to conduct remote Execution as part of Lateral Movement and/or to run a process under the context of a specified account (such as SYSTEM). Similar to System Binary Proxy Execution, adversaries have also abused the Windows Task Scheduler to potentially mask one-time execution under signed/trusted system processes.[3]
Adversaries may also create "hidden" scheduled tasks (i.e. Hide Artifacts) that may not be visible to defender tools and manual queries used to enumerate tasks. Specifically, an adversary may hide a task from `schtasks /query` and the Task Scheduler by deleting the associated Security Descriptor (SD) registry value (where deletion of this value must be completed using SYSTEM permissions).[4][5] Adversaries may also employ alternate methods to hide tasks, such as altering the metadata (e.g., `Index` value) within associated registry keys.[6]
Analyst context for executives and security teams
Windows Scheduled Tasks matter because they are a normal administration feature that can also provide adversaries with execution, persistence, and privilege-escalation paths. For leaders, the risk is not just that a task exists; it is whether the organization can distinguish approved automation from unauthorized recurring or one-time execution, including tasks hidden from common queries.
Executive priority
Prioritize this technique where Windows endpoints or servers support critical business operations, privileged administration, remote management, or regulated evidence requirements. Executive questions should focus on whether scheduled task creation and execution are audited, whether privileged accounts can create tasks broadly, and whether incident responders can quickly identify suspicious or hidden tasks during containment decisions.
Technical view
For SOC, detection engineering, and IR teams, validate coverage for suspicious scheduled task creation and execution on Windows, aligned to DET0441. Review task creation through schtasks, Task Scheduler GUI, WMI, netapi32, .NET wrappers, and PowerShell Invoke-CimMethod paths where telemetry supports it. Investigate tasks configured for startup, recurring execution, remote execution, or execution as privileged accounts such as SYSTEM. Include checks for hidden-task behavior, especially deletion of the Security Descriptor registry value or suspicious changes to scheduled task registry metadata such as Index values.
Likely telemetry
- Windows Task Scheduler operational and task registration events
- Windows audit events for other object access where configured
- Command-line process creation involving schtasks or PowerShell task creation methods
- WMI/CIM activity related to scheduled task creation
- Registry telemetry for scheduled task keys, including SD value deletion or metadata alteration
Detection direction
- Validate that task creation, modification, execution, and deletion are logged on relevant Windows systems; ATT&CK does not provide official detection text for this object.
- Tune detections around unusual task names, paths, triggers, run-as accounts, remote creation patterns, and tasks launching from nonstandard or user-writable locations, while accounting for legitimate administration and software maintenance.
- Add specific logic for hidden-task indicators, including removal of the SD registry value and suspicious scheduled task registry metadata changes.
- Correlate scheduled task activity with privileged account use, WMI activity, PowerShell Invoke-CimMethod usage, and lateral movement context when available.
- Confirm that common manual queries such as schtasks /query are not the only validation method, because hidden tasks may evade those views.
Mitigation priorities
- Apply user account management and least privilege so ordinary users and unnecessary service accounts cannot create or modify scheduled tasks broadly.
- Strengthen privileged account management for administrators and accounts capable of running tasks as SYSTEM or creating remote scheduled tasks.
- Harden operating system configuration and restrict unnecessary task scheduling pathways where operationally feasible.
- Enable and review auditing for scheduled task activity and related registry changes so detections and compliance evidence have reliable source data.
- Regularly review scheduled tasks on critical Windows systems and compare approved automation against observed task inventory.
Analyst notes and limits
This technique is a Windows sub-technique of Scheduled Task/Job and is mapped to execution, persistence, and privilege escalation. Relationship context shows broad historical use by many campaigns and groups, but that should be treated as relevance context rather than proof of current activity in any environment. The supplied mitigation relationships emphasize account management, privileged account management, operating system configuration, and auditing.
Official ATT&CK detection text is not provided for this object. Local conclusions require environment-specific baselines of legitimate scheduled tasks, enabled Windows logging, registry visibility, process command-line collection, and privileged account context. The supplied fields support Windows only for this sub-technique.

Groups, software, and campaigns
G0022: APT3
APT3 is a China-based threat group that researchers have attributed to China's Ministry of State Security.[1][2] This group is responsible for the campaigns known as Operation Clandestine Fox, Operation Clandestine Wolf, and Operation Double Tap.[1][3] As of June 2015, the group appears to have shifted from targeting primarily US victims to primarily political organizations in Hong Kong.[4]
G0080: Cobalt Group
Cobalt Group is a financially motivated threat group that has primarily targeted financial institutions since at least 2016. The group has conducted intrusions to steal money via targeting ATM systems, card processing, payment systems and SWIFT systems. Cobalt Group has mainly targeted banks in Eastern Europe, Central Asia, and Southeast Asia. One of the alleged leaders was arrested in Spain in early 2018, but the group still appears to be active. The group has been known to target organizations in order to use their access to then compromise additional victims.[1][2][3][4][5][6][7] Reporting indicates there may be links between Cobalt Group and both the malware Carbanak and the group Carbanak.[8]
G0091: Silence
Silence is a financially motivated threat actor targeting financial institutions in different countries. The group was first seen in June 2016. Their main targets reside in Russia, Ukraine, Belarus, Azerbaijan, Poland and Kazakhstan. They compromised various banking systems, including the Russian Central Bank's Automated Workstation Client, ATMs, and card processing.[1][2]
G0114: Chimera
G0040: Patchwork
Patchwork is a cyber espionage group that was first observed in December 2015. While the group has not been definitively attributed, circumstantial evidence suggests the group may be a pro-Indian or Indian entity. Patchwork has been seen targeting industries related to diplomatic and government agencies. Much of the code used by this group was copied and pasted from online forums. Patchwork was also seen operating spearphishing campaigns targeting U.S. think tank groups in March and April of 2018.[1] [2][3][4]
G1034: Daggerfly
Daggerfly is a People's Republic of China-linked APT entity active since at least 2012. Daggerfly has targeted individuals, government and NGO entities, and telecommunication companies in Asia and Africa. Daggerfly is associated with exclusive use of MgBot malware and is noted for several potential supply chain infection campaigns.[1][2][3][4]
G0046: FIN7
FIN7 is a financially-motivated threat group that has been active since 2013. FIN7 has targeted the retail, restaurant, hospitality, software, consulting, financial services, medical equipment, cloud services, media, food and beverage, transportation, pharmaceutical, and utilities industries in the United States. A portion of FIN7 was operated out of a front company called Combi Security and often used point-of-sale malware for targeting efforts. Since 2020, FIN7 shifted operations to big game hunting (BGH), including use of REvil ransomware and their own Ransomware-as-a-Service (RaaS), Darkside. FIN7 may be linked to the Carbanak Group, but multiple threat groups have been observed using Carbanak, leading these groups to be tracked separately.[1][2][3][4][5][6][7]
G1018: TA2541
TA2541 is a cybercriminal group that has been targeting the aviation, aerospace, transportation, manufacturing, and defense industries since at least 2017. TA2541 campaigns are typically high volume and involve the use of commodity remote access tools obfuscated by crypters and themes related to aviation, transportation, and travel.[1][2]
G0093: GALLIUM
GALLIUM is a cyberespionage group that has been active since at least 2012, primarily targeting telecommunications companies, financial institutions, and government entities in Afghanistan, Australia, Belgium, Cambodia, Malaysia, Mozambique, the Philippines, Russia, and Vietnam. This group is particularly known for launching Operation Soft Cell, a long-term campaign targeting telecommunications providers.[1] Security researchers have identified GALLIUM as a likely Chinese state-sponsored group, based in part on tools used and TTPs commonly associated with Chinese threat actors.[1][2][3]
G0034: Sandworm Team
Sandworm Team is a destructive threat group that has been attributed to Russia's General Staff Main Intelligence Directorate (GRU) Main Center for Special Technologies (GTsST) military unit 74455.[1][2] This group has been active since at least 2009.[3][4][5][6]
In October 2020, the US indicted six GRU Unit 74455 officers associated with Sandworm Team for the following cyber operations: the 2015 and 2016 attacks against Ukrainian electrical companies and government organizations, the 2017 worldwide NotPetya attack, targeting of the 2017 French presidential campaign, the 2018 Olympic Destroyer attack against the Winter Olympic Games, the 2018 operation against the Organisation for the Prohibition of Chemical Weapons, and attacks against the country of Georgia in 2018 and 2019.[1][2] Some of these were conducted with the assistance of GRU Unit 26165, which is also referred to as APT28.[7]
G1043: BlackByte
BlackByte is a ransomware threat actor operating since at least 2021. BlackByte is associated with several versions of ransomware also labeled BlackByte Ransomware. BlackByte ransomware operations initially used a common encryption key allowing for the development of a universal decryptor, but subsequent versions such as BlackByte 2.0 Ransomware use more robust encryption mechanisms. BlackByte is notable for operations targeting critical infrastructure entities among other targets across North America.[1][2][3][4][5]
G1001: HEXANE
HEXANE is a cyber espionage threat group that has targeted oil & gas, telecommunications, aviation, and internet service provider organizations since at least 2017. Targeted companies have been located in the Middle East and Africa, including Israel, Saudi Arabia, Kuwait, Morocco, and Tunisia. HEXANE's TTPs appear similar to APT33 and OilRig but due to differences in victims and tools it is tracked as a separate entity.[1][2][3][4]
S0588: GoldMax
GoldMax is a second-stage C2 backdoor written in Go with Windows and Linux variants that are nearly identical in functionality. GoldMax was discovered in early 2021 during the investigation into the SolarWinds Compromise, and has likely been used by APT29 since at least mid-2019. GoldMax uses multiple defense evasion techniques, including avoiding virtualization execution and masking malicious traffic.[1][2][3]
S9001: SystemBC
SystemBC is a malware family offered as a malware-as-a-service (MaaS) that is used to establish command and control and facilitate follow-on activity, including ransomware deployment.SystemBC executes a variety of tasks including setting up SOCKS5 proxies, maintaining persistence, ingesting malicious files, and handing C2 communication. SystemBC was first detected in 2018, and has been used by Wizard Spider since at least 2020, and by FIN7 since at least 2022.[1][2][3][4][5]
S0648: JSS Loader
JSS Loader is Remote Access Trojan (RAT) with .NET and C++ variants that has been used by FIN7 since at least 2020.[1][2]

S1014: DanBot
S0170: Helminth
S1015: Milan
S0697: HermeticWiper
S1166: Solar
Solar is a C#/.NET backdoor that was used by OilRig during the Outer Space campaign to download, execute, and exfiltrate files.[1]
S0266: TrickBot
TrickBot is a Trojan spyware program written in C++ that first emerged in September 2016 as a possible successor to Dyre. TrickBot was developed and initially used by Wizard Spider for targeting banking sites in North America, Australia, and throughout Europe; it has since been used against all sectors worldwide as part of "big game hunting" ransomware campaigns.[1][2][3][4]
S0335: Carbon
S0126: ComRAT
C0024: SolarWinds Compromise
The SolarWinds Compromise was a sophisticated supply chain cyber operation conducted by APT29 that was discovered in mid-December 2020. APT29 used customized malware to inject malicious code into the SolarWinds Orion software build process that was later distributed through a normal software update; they also used password spraying, token theft, API abuse, spear phishing, and other supply chain attacks to compromise user accounts and leverage their associated access. Victims of this campaign included government, consulting, technology, telecom, and other organizations in North America, Europe, Asia, and the Middle East. This activity has been labled the StellarParticle campaign in industry reporting.[1] Industry reporting also initially referred to the actors involved in this campaign as UNC2452, NOBELIUM, Dark Halo, and SolarStorm.[2][3][4][5][1][6][7][8]
In April 2021, the US and UK governments attributed the SolarWinds Compromise to Russia's Foreign Intelligence Service (SVR); public statements included citations to APT29, Cozy Bear, and The Dukes.[9][10][11] The US government assessed that of the approximately 18,000 affected public and private sector customers of Solar Winds’ Orion product, a much smaller number were compromised by follow-on APT29 activity on their systems.[12]
C0058: SharePoint ToolShell Exploitation
The SharePoint ToolShell Exploitation campaign was conducted in July 2025 and encompassed the first waves of exploitation against incompletely patched spoofing (CVE-2025-49706) and remote code execution (CVE-2025-49704) vulnerabilities affecting on-premises Microsoft SharePoint servers. Later patched and updated as CVE-2025-53770 and CVE-2025-53771, the ToolShell vulnerabilities were widely exploited including by China-based ransomware actor Storm-2603 and espionage actors Threat Group-3390 and ZIRCONIUM. SharePoint ToolShell Exploitation targeted multiple regions and industries including finance, education, energy, and healthcare across Asia, Europe, and the United States.[1][2][3][4][5]
C0034: 2022 Ukraine Electric Power Attack
The 2022 Ukraine Electric Power Attack was a Sandworm Team campaign that used a combination of GOGETTER, Neo-REGEORG, CaddyWiper, and living of the land (LotL) techniques to gain access to a Ukrainian electric utility to send unauthorized commands from their SCADA system.[1][2]
C0017: C0017
C0017 was an APT41 campaign conducted between May 2021 and February 2022 that successfully compromised at least six U.S. state government networks through the exploitation of vulnerable Internet facing web applications. During C0017, APT41 was quick to adapt and use publicly-disclosed as well as zero-day vulnerabilities for initial access, and in at least two cases re-compromised victims following remediation efforts. The goals of C0017 are unknown, however APT41 was observed exfiltrating Personal Identifiable Information (PII).[1]
C0001: Frankenstein
Frankenstein was described by security researchers as a highly-targeted campaign conducted by moderately sophisticated and highly resourceful threat actors in early 2019. The unidentified actors primarily relied on open source tools, including Empire. The campaign name refers to the actors' ability to piece together several unrelated open-source tool components.[1]
C0044: Juicy Mix
C0030: Triton Safety Instrumented System Attack
Triton Safety Instrumented System Attack was a campaign employed by TEMP.Veles which leveraged the Triton malware framework against a petrochemical organization.[1] The malware and techniques used within this campaign targeted specific Triconex Safety Controllers within the environment.[2] The incident was eventually discovered due to a safety trip that occurred as a result of an issue in the malware.[3]
