Hands-On AWS Penetration Testing with Kali Linux

Persistence

We aren't going to dive too deeply into persistence because we covered that in the last chapter, but, as with the other methods of attacking Lambda, persistence can be established with new Lambda functions or by editing existing Lambda functions. Persistence can also mean a few different things. Do you want persistence access to a bash shell for a Lambda function, do you want persistent access to the AWS environment, or do you want both? It is all about context and what works best for the situation you are in as an attacker. It might even be valuable to backdoor multiple Lambda functions, in case one gets caught and removed by a defender.
