Download Instance SSH keys & DB passwords

They won't be changed probably so just having them is a good option for persistence

Backdoor Instances

An attacker could get access to the instances and backdoor them:

Using a traditional rootkit for example
Adding a new public SSH key
Expose a port with port knocking with a backdoor

DNS persistence

If domains are configured:

Create a subdomain pointing your IP so you will have a subdomain takeover
Create SPF record allowing you to send emails from the domain
Configure the main domain IP to your own one and perform a MitM from your IP to the legit ones
