/home/ : The typical directory for user profiles in Linux/Unix systems.

To prevent an application from ever being able to read its own credentials via a URL: callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials

Let's dissect the URL into its components: /home/ : The typical directory for user profiles

: This is a URI schema used to instruct an application to read a local file, often seen in scenarios where an application fetches content from a user-supplied URL. /home/*/.aws/credentials : This is the target path. callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials

The paper explores how an attacker can exploit URL redirection and improper handling of local file protocols to exfiltrate sensitive AWS configuration files.

What (e.g., Python, Node.js, Java) your application uses to process these URLs?
