Threat findings are generated by\n[threat detectors](/security-command-center/docs/concepts-security-sources#threats) when they detect\na potential threat in your cloud resources. For a full list of available threat findings, see [Threat findings index](/security-command-center/docs/threat-findings-index).\n\nOverview\n\nTo escalate privilege, a potentially malicious actor attempted to create a new\n`RoleBinding` or `ClusterRoleBinding` object for the [`cluster-admin`](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#user-facing-roles)\nrole.\n\nHow to respond\n\nTo respond to this finding, do the following:\n\nStep 1: Review finding details\n\n1. Open the `Privilege Escalation: Creation of sensitive Kubernetes bindings`\n finding as directed in [Reviewing findings](/security-command-center/docs/how-to-investigate-threats#reviewing_findings).\n The details panel for the finding opens to the **Summary** tab.\n\n2. On the **Summary** tab, review the information in the following sections:\n\n - **What was detected** , especially the following fields:\n - **Principal email**: the account that made the call.\n - **Kubernetes bindings** : the sensitive Kubernetes binding or `ClusterRoleBinding` that was created.\n - **Affected resource** , especially the following fields:\n - **Resource display name**: the Kubernetes cluster where the action occurred.\n - **Related links** , especially the following fields:\n - **Cloud Logging URI**: link to Logging entries.\n - **MITRE ATT\\&CK method**: link to the MITRE ATT\\&CK documentation.\n - **Related findings**: links to any related findings.\n\nStep 2: Check logs\n\n1. On the **Summary** tab of the finding details in the Google Cloud console, go to **Logs Explorer** by clicking the link in the **Cloud Logging URI** field.\n2. Check for other actions taken by the principal by using the following\n filters:\n\n - `resource.labels.cluster_name=\"`\u003cvar class=\"edit\" translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e`\"`\n - `protoPayload.authenticationInfo.principalEmail=\"`\u003cvar class=\"edit\" translate=\"no\"\u003ePRINCIPAL_EMAIL\u003c/var\u003e`\"`\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e: the value that you noted in the\n **Resource display name** field in the finding details.\n\n - \u003cvar translate=\"no\"\u003ePRINCIPAL_EMAIL\u003c/var\u003e: the value that you noted in the\n **Principal email** field in the finding details.\n\nStep 3: Research attack and response methods\n\n1. Review MITRE ATT\\&CK framework entries for this finding type: [Privilege Escalation](https://attack.mitre.org/tactics/TA0004/).\n2. Confirm the sensitivity of the binding created and if the roles are necessary for the subjects.\n3. For bindings, you can check the subject and investigate whether the subject needs the role it is binded to.\n4. Determine whether there are other signs of malicious activity by the principal in the logs.\n5. If the [principal email](#privilege_escalation_create_rbac_finding) isn't a\n service account, contact the owner of the account to confirm whether the\n legitimate owner conducted the action.\n\n If the principal email is a service account (IAM or\n Kubernetes), identify the source of the action to determine its\n legitimacy.\n6. To develop a response plan, combine your investigation results with\n MITRE research.\n\nWhat's next\n\n- Learn [how to work with threat\n findings in Security Command Center](/security-command-center/docs/how-to-investigate-threats).\n- Refer to the [Threat findings index](/security-command-center/docs/threat-findings-index).\n- Learn how to [review a\n finding](/security-command-center/docs/how-to-investigate-threats#reviewing_findings) through the Google Cloud console.\n- Learn about the [services that\n generate threat findings](/security-command-center/docs/concepts-security-sources#threats)."]]
