MyJoomla is a Security and Management Tool for Joomla.
I discovered a client’s Joomla v2.5.17 installation was hacked. The MyJoomla Joomla security scan is very helpful in taking a look under the hood. It doesn’t look at the site from the outside, it’s actually an Extension, so it audits the site from the inside. It took ~6 hours for the full scan to run and spit out a very reader-friendly, well-designed report.
