AWS Credentials Leaks
A common way to obtain access or information about an AWS account is by searching for leaks. You can search for leaks using google dorks, checking the public repos of the organization and the workers of the organization in Github or other platforms, searching in credentials leaks databases... or in any other part you think you might find any information about the company and its cloud infa.

Cross Account Attacks
In the talk Breaking the Isolation: Cross-Account AWS Vulnerabilities it's presented how some services allow(ed) any AWS account accessing them because AWS services without specifying accounts ID were allowed.
During the talk they specify several examples, such as S3 buckets allowing cloudtrail (of any AWS account) to write to them:

Other services found vulnerable:
- AWS Config
- Serverless repository
Tools
- cloud_enum: Multi-cloud OSINT tool. Find public resources in AWS, Azure, and Google Cloud. Supported AWS services: Open / Protected S3 Buckets, awsapps (WorkMail, WorkDocs, Connect, etc.)
