Which AWS group or team should the company notify?

Explanations:

The AWS Abuse team is specifically designated to handle reports of abuse or illegal activities occurring on AWS resources. They investigate claims of violations of AWS policies and terms of service, making them the appropriate contact for this situation.

The AWS Support team primarily assists customers with technical issues and general support inquiries. While they may be able to provide guidance, they are not specifically trained to handle reports of illegal activities or abuse.

AWS technical account managers focus on providing account management and support to specific AWS customers, but they are not responsible for handling abuse reports. They may assist in escalations, but they do not directly address issues of illegal activities.

The AWS Professional Services team provides consulting services and helps organizations with cloud strategies and implementations. They do not address abuse or illegal activities on AWS resources, making them an inappropriate contact for this situation.
