Container Service

Executive Summary

Container Service (T1543.005) is a MITRE ATT&CK technique associated with Persistence, Privilege Escalation. Adversaries may create or modify container or container cluster management tools that run as daemons, agents, or services on individual hosts.

Why Attackers Use It

Attackers use Container Service because it provides a reliable way to advance their objective within the Persistence, Privilege Escalation tactic, often with a favorable balance of impact versus detectability on Containers environments. Defenders should assess this behavior in the context of the affected platform and adjacent activity rather than treating it as a standalone indicator.

MITRE Description

Adversaries may create or modify container or container cluster management tools that run as daemons, agents, or services on individual hosts. These include software for creating and managing individual containers, such as Docker and Podman, as well as container cluster node-level agents such as kubelet. By modifying these services, an adversary may be able to achieve persistence or escalate their privileges on a host.

For example, by using the docker run or podman run command with the restart=always directive, a container can be configured to persistently restart on the host.(Citation: AquaSec TeamTNT 2023) A user with access to the (rootful) docker command may also be able to escalate their privileges on the host.(Citation: GTFOBins Docker)

In Kubernetes environments, DaemonSets allow an adversary to persistently Deploy Containers on all nodes, including ones added later to the cluster.(Citation: Aquasec Kubernetes Attack 2023)(Citation: Kubernetes DaemonSet) Pods can also be deployed to specific nodes using the nodeSelector or nodeName fields in the pod spec.(Citation: Kubernetes Assigning Pods to Nodes)(Citation: AppSecco Kubernetes Namespace Breakout 2020)

Note that containers can also be configured to run as Systemd Services.(Citation: Podman Systemd)(Citation: Docker Systemd)

Attack Flow

1. Attacker gains the prerequisite access or context described below.
2. Attacker executes Container Service to achieve its tactical objective (Persistence, Privilege Escalation).
3. Resulting access/data/effect is leveraged to advance the broader attack chain (see Related Techniques).

Prerequisites

• Platform(s): Containers
• ATT&CK does not define one universal permission requirement for this technique. Establish the required access from the observed implementation and affected platform.

Common Tools

• Tool attribution is implementation-specific. Use ATT&CK procedure examples and local telemetry to identify the binaries, services, scripts, accounts, or cloud resources involved.

Commands

No universal command represents Container Service. Capture the exact command line, arguments, parent process, account, host, and execution time from the investigated environment; do not operationalize unverified examples.

Network Traffic

• Network observability is implementation-dependent. Review DNS, proxy, firewall, flow, authentication, and packet telemetry around the activity window, then correlate remote endpoints and protocol behavior with host evidence.

Detection Opportunities

No MITRE detection guidance published for this technique.

Relevant ATT&CK Data Sources: N/A

Sigma Rules

A universal Sigma rule would create unreliable results because this technique has no single guaranteed observable. Build detection logic from a documented behavior and supported data source, scope it to the affected platform, and validate it against benign administrative activity before deployment.

Splunk Queries

Start with the data sources named in the detection section. Scope searches by asset, identity, and time window; correlate the primary behavior with preceding access and subsequent actions. A portable query is intentionally not provided where the technique lacks a universal schema or observable.

Investigation Workflow

1. Confirm that the observed behavior is consistent with Container Service and rule out expected administrative or application activity.
2. Establish the first-seen time, initiating identity, source system, target system, and affected resources.
3. Collect relevant host, identity, network, cloud, and application telemetry for the surrounding time window.
4. Correlate parent and child activity, remote connections, file or configuration changes, and related ATT&CK techniques.
5. Determine scope by searching for the same observable across peer assets and identities.
6. Preserve volatile evidence and record confidence, assumptions, and telemetry gaps before containment.

Containment

1. Isolate affected host(s)/account(s) identified during investigation.
2. Revoke or rotate any credentials/tokens potentially exposed.
3. Apply the mitigations listed below where not already enforced.
4. Validate no related techniques (see Related Techniques) were chained against the same asset.

Mitigation

• M1054 -- Software Configuration: Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats.
• M1018 -- User Account Management: User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation.
