How attackers use it: Automated bots scanning for /vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php. Combine with "index of" to find open listings.

The feature you're referring to seems to relate to a specific configuration or setup within a PHP environment, possibly involving PHPUnit, a popular testing framework for PHP. The string you've provided, "index of vendor phpunit phpunit src util php evalstdinphp hot", seems to hint at a particular file path or configuration setting rather than a widely recognized feature by that name.

If your server logs show repeated GET requests to eval-stdin.php with odd user agents, you are likely already being scanned. : When installing packages via Composer, ensure you're

folder (where PHPUnit is installed via Composer) publicly accessible on a web server, this file becomes a major security risk.

When a web server does not find a default index file (like index.php or index.html ) in a folder, and directory listing is enabled, it generates a page showing all files and subdirectories.
