If you’re looking at a site that’s been defaced, filled with Spam links, find your site has been disabled and replaced with a demand for money or you’ve found out that you got shut down by your web host for sending Spam, then you’ve probably been hacked.
Recently, the Schweb team worked on a site that had been hacked. This wasn’t an instance of national security, but to our customer, and to us, it was important. Hackers exploited this site’s vulnerability. This site was built on Joomla.
