아마존(Amazon Web Service) Cloudtail 해킹 과금 결제 분석

 

Amazon Elastic Container Service 보면 테스크 정의 (task-definitions) 과 클러스터(cluster)가 엄청 많이 생겨서

리소스 자원을 미친듯이 잡아먹는 것을 볼 수 있음

 

노가다 해서 지우기 엄청 힘들다..

Thank you for getting back to us.

Please note that we can’t view the exact root cause. However, the following are common patterns of suspicious activity:

- An unpatched Amazon Elastic Compute Cloud (EC2) instance is infected and became a botnet agent.
- Credentials or access keys have been exposed.
- An overly aggressive web crawler might be classified as a denial-of-service attack by some internet sites.
- An end user posted malware files on a public Amazon S3 bucket.
- Sometimes internet users mistakenly report legitimate activities as abuse.

It is a best practice to monitor your account and its resources for any unusual activity or unauthorized access.
AWS CloudTrail and Amazon GuardDuty provide additional insight into the reasons for unauthorized activity.
For more information about AWS CloudTrail, see the following documentation:
https://docs.aws.amazon.com/awscloudtrail/latest/userguide/view-cloudtrail-events.html
https://docs.aws.amazon.com/awscloudtrail/latest/userguide/logging-insights-events-with-cloudtrail.html

Important: To secure and restore your account, complete the below steps, this process leads to account reinstatement and billing review for the unauthorized charges.

Step 1: Terminate IAM Roles and Policies
. Access the IAM roles console here: https://us-east-1.console.aws.amazon.com/iamv2/home?region=us-east-1#/roles
. Select the check box next to the role name that you want to delete.
. At the top of the page, choose Delete.
. In the confirmation dialog box, review the last accessed information, which shows when each of the selected roles last accessed an AWS service. This to confirm if the role is currently active.
. If you want to proceed, enter the name of the role in the text input field and choose Delete.

Step 2: If you haven't created the Organization, please proceed with the following instructions to delete the Role.

We need to go through these 3 Documents
-> Delete your IAM Identity Center configuration https://docs.aws.amazon.com/singlesignon/latest/userguide/regions.html
-> Delete permission sets https://docs.aws.amazon.com/singlesignon/latest/userguide/howtoremovepermissionset.html
-> Deleting a service-linked role for IAM Identity Center https://docs.aws.amazon.com/singlesignon/latest/userguide/using-service-linked-roles.html#delete-slr

-> To Delete the organization by removing the management account follow this guide:
https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_org_delete.html

I will add better instruction here (Step by Step) So It will be easier to follow:
- Go to the Settings in the Organization Console direct link here: https://us-east-1.console.aws.amazon.com/organizations/v2/home/settings
In the Settings page, choose Delete organization.

In the Delete organization confirmation dialog box, enter the organization's ID which is displayed in the line above the text box. Then, choose Delete organization.
- The roles should be deleted automatically. If not please go here: https://us-east-1.console.aws.amazon.com/iamv2/home?region=us-east-1#/roles
Select and delete the SSO and Organization Roles.

If you need assistance with the steps, choose "Phone" or "Chat" option from the Support Center: https://console.aws.amazon.com/support/home
