The .aws/credentials file is a configuration file used by AWS CLI to store access keys and other credentials. This file typically resides in the user's home directory, e.g., ~/.aws/credentials . The file contains sensitive information, including:
The server returns the contents of the credential file encoded in base64, which is then decoded to get the plaintext credentials. Key Observations
The URL you've mentioned is:
: This specific filter instructs PHP to take the contents of the target file and encode it into a Base64 string. Attackers use this because Base64 text often bypasses Web Application Firewalls (WAFs) and prevents the server from executing the file (e.g., if it were a .php file).
: This part of the string looks like a URL-encoded or modified path segment.
The target file, /root/.aws/credentials , is a critical configuration file used by the AWS Command Line Interface (CLI) and SDKs.
Example output when the attack succeeds:
$encodedCredentials = encodeCredentials($accessKeyId, $secretAccessKey); echo "Encoded Credentials: $encodedCredentials\n";
