If you see this in your logs, you are under attack. If you see this in your search console, your server is compromised. The combination of a mutable eval statement, a test file in production, and directory indexing creates a perfect storm for system takeover. The attacker sent a POST request with a
PHPUnit should never exist on a live production server. Clean your environment by running Composer with the appropriate flag to strip out all development packages: composer install --no-dev --optimize-autoloader Use code with caution. 2. Block Access via .htaccess (Apache)
Search your HTTP access logs for any requests containing the phrase eval-stdin.php to see if payloads were delivered. The root cause was the simple presence of eval-stdin
An attacker only needs to locate the exposed path and transmit an HTTP POST request containing malicious payloads (such as web shells or reverse proxy code) starting with a standard
Now they can execute any PHP command. Common malicious payloads:
