Verify whether the change was done intentionally by a member, or if it was implemented by an adversary to introduce new access to your organization.\n2. Check logs using the following filters:\n\n ```\n protopayload.resource.labels.instance_id=INSTANCE_ID\n protoPayload.serviceName=\"compute.googleapis.com\"\n (protoPayload.metadata.instanceMetaData.addedMetadataKey : \"ssh-keys\" OR protoPayload.metadata.instanceMetaData.modifiedMetadataKey : \"ssh-keys\" )\n logName=\"organizations/ORGANIZATION_ID/logs/cloudaudit.googleapis.com%2Factivity\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the `gceInstanceId` listed in the finding\n - \u003cvar translate=\"no\"\u003eORGANIZATION_ID\u003c/var\u003e: your organization ID\n3.
