Hello Trương Lê Vĩnh Phúc,
Thanks for your question.
You could check Activity logs on those resources to get some details on when they were created and by who. I will also suggest you check your access on your resource scope. Go to subscriptions and navigate to IAM to see the roles assigned on your Azure subscription.
