Currently, for a class to be scanned by the main detector, it needs to meet at least one of the following conditions:

• Implement a Lambda handler Interface (RequestHandler or RequestStreamHandler)

• Has a method that receives either (Map, com.amazonaws.services.lambda.runtime.Context) or (InputStream, OutputStream, com.amazonaws.services.lambda.runtime.Context) as parameters. This method would be considered a Lambda Handler.

The issue here is that in general, we don't need to implement an interface to be able to have a Lambda function. For example, this is a valid Lambda handler class:

  public class NewHandler {
      public String handleRequest(){
          //code
      }
  }

Solving this problem will allow us to scan most Lambda Handler classes that are currently falling through the cracks.
