Attackers often double URL-encode this payload ( %252F for / ) to bypass security filters (WAF) that scan for malicious strings.
Let's break down the URL into its components:
: This is the target file. In this case, the attacker is aiming for the AWS credentials file, which typically contains sensitive access_key_id and secret_access_key tokens for Amazon Web Services. Why Base64 Encoding?
return $content; catch (Exception $e) // Handle exception return null;

: This specifies the target file on the server.
