Also some more observations below:

1) some 20 organisations were created within our Root all with email id with same domain (co.jp) 2) attacker had created multiple fargate templates 3) they created resources in 16-17 AWS regions 4) they requested to raise SES,WS Fargate Resource Rate Quota Change was requested, sage maker Notebook maintenance - we have no need of using these instances (recd an email from aws for all of this) 5) in some of the emails i started seeing a new name added (random name @outlook.com)
