Query: indicators of Additional Container Cluster Roles
Matching passage: T1098.006 Additional Container Cluster Roles. Tactics: persistence, privilege escalation. Description: An adversary may add additional roles or permissions to an adversary-controlled user or service account to maintain persistent access to a container orchestration system. For example, an adversary with sufficient permissions may create a RoleBinding or a ClusterRoleBinding to bind a Role or ClusterRole to a Kubernetes account.(Citation: Kubernetes RBAC)(Citation: Aquasec Kubernetes Attack 2023) Where attribute-based access control (ABAC) is in use, an adversary with sufficient permissions may modify a Kubernetes ABAC policy to give the target account additional permissions.(Citation: Kuberentes ABAC) This account modification may immediately follow [Create Account](https://attack.mitre.org/techniques/T1136) or other malicious account activity. Adversaries may also modify existing [Valid Accounts](https://attack.mitre.org/techniques/T1078) that they have compromised. Note that where container orchestration systems are deployed in cloud environments, as with Google Kubernetes Engine, Amazon Elastic Kubernetes Service, and Azure Kubernetes Service, cloud-based role-based access control (RBAC) assignments or ABAC policies can often be used in place of or in addition to local permission assignments.(Citation: Google Cloud Kubernetes IAM)(Citation: AWS EKS IAM Roles for Service Accounts)(Citation: Microsoft Azure Kubernetes Service Service Accounts) In these cases, this technique may be used in conjunction with [Additional Cloud Roles](https://attack.mitre.org/techniques/T1098/003).
Near-miss passage: T1098.001 Additional Cloud Credentials. Tactics: persistence, privilege escalation. Description: Adversaries may add adversary-controlled credentials to a cloud account to maintain persistent access to victim accounts and instances within the environment. For example, adversaries may add credentials for Service Principals and Applications in addition to existing legitimate credentials in Azure / Entra ID.(Citation: Microsoft SolarWinds Customer Guidance)(Citation: Blue Cloud of Death)(Citation: Blue Cloud of Death Video) These credentials include both x509 keys and passwords.(Citation: Microsoft SolarWinds Customer Guidance) With sufficient permissions, there are a variety of ways to add credentials including the Azure Portal, Azure command line interface, and Azure or Az PowerShell modules.(Citation: Demystifying Azure AD Service Principals) In infrastructure-as-a-service (IaaS) environments, after gaining access through [Cloud Accounts](https://attack.mitre.org/techniques/T1078/004), adversaries may generate or import their own SSH keys using either the <code>CreateKeyPair</code> or <code>ImportKeyPair</code> API in AWS or the <code>gcloud compute os-login ssh-keys add</code> command in GCP.(Citation: GCP SSH Key Add) This allows persistent access to instances within the cloud environment without further usage of the compromised cloud accounts.(Citation: Expel IO Evil in AWS)(Citation: Expel Behind the Scenes) Adversaries may also use the <code>CreateAccessKey</code> API in AWS or the <code>gcloud iam service-accounts keys create</code> command in GCP to add access keys to an account. Alternatively, they may use the <code>CreateLoginProfile</code> API in AWS to add a password that can be used to log into the AWS Management Console for [Cloud Service Dashboard](https://attack.mitre.org/techniques/T1538).(Citation: Permiso Scattered Spider 2023)(Citation: Lacework AI Resource Hijacking 2024) If the target account has different permissions from the requesting account, the adversary may also be able to escalate their privileges in the environment (i.e. [Cloud Acc
