: On Linux/Unix, it is usually stored in ~/.aws/credentials . If a web application is running with root privileges, the path becomes /root/.aws/credentials .
They obtain the plaintext credentials.
The server might respond with the base64 encoded content of the file. 4. Remediation and Defense
What (or raw PHP setup) is your application running? : On Linux/Unix, it is usually stored in ~/

The request seems to be attempting to access sensitive credentials stored in an AWS credentials file located at /root/.aws/credentials . The use of filter=read and convert=base64_encode suggests that the attacker may be trying to read and encode the contents of the file. The server might respond with the base64 encoded
The raw payload often appears URL-encoded in server logs to bypass basic web application firewall (WAF) filters:
To mitigate potential security risks associated with this URL:
In modern web application security, File Inclusion (FI) vulnerabilities—specifically Local File Inclusion (LFI)—remain a top threat. A particularly dangerous variant occurs when PHP’s php:// wrapper is used to read sensitive files. To understand how this attack works
Instead of looking for standard system files like /etc/passwd , this specific string targets the absolute path of the root user's AWS CLI credential configuration file.
These keys provide authorized access to AWS services (S3, EC2, RDS, etc.).
To understand how this attack works, we must first normalize the string. The payload contains URL-encoded characters ( -3A- , -2F- ) which are commonly used by attackers to bypass simple Web Application Firewall (WAF) filters or to match specific routing parameters in a Content Management System (CMS) or API framework. When URL-decoded, the core attack vector looks like this:
: If your application is running on an EC2 instance, never store hardcoded credentials in /root/.aws/credentials . Instead, use IAM Roles for EC2 . This provides the application with temporary, rotating credentials that are much harder to steal.
