A friends drupal site was hacked. What is strange is that the root directory of the installation at the hosting company (let us call it rootdir) was copied (or renamed) rootdir_hacked and the directory rootdir was left one file index.html saying the site is under update.
What I do not understand is how can the hacker create/copy a directory to somewhere outside the rootdir. Shouldn't the security settings of the hosting company prevent this without access via ftp?
