It may be a bot-generated attempt to index your site, or something similar - it costs very little to input names into a script and run such searches.
That being said, I recently came across this tool for running a security audit on your own Joomla sites: https://audit.myjoomla.com/ The first audit is free, and you can pay either per-audit after that, or get a subscription (monthly) to run as many as you would like. It works by uploading a component to your Joomla site, and the audit site connects to it and runs checks against your site / server for known issues (exploitable code, bad / good practices, versions of Joomla, PHP, etc.). The service is run by Phil Taylor, whom I have seen in the Joomla community for a while - I feel the service can be trusted, and is not a hack / vulnerability itself. -Geoffrey _______________________________________________ New York PHP SIG: Joomla!
