All right guys, I just did a fresh installation for a wordpress blog and downloaded the database to check the data, and guess what I found? Someone stuff a cloak backlink into my wordpress blog! Code: # Data contents of table `wp_links` # INSERT INTO `wp_links` VALUES (8, 'http://wordpresssupplies.com/', 'Wordpress Themes', '', '', 'Download Free Wordpress Themes and Plugins', 'Y', 2, 0, '0000-00-00 00:00:00', '', '', ''); I had not uploaded any themes into the wp blog, so it should not be the themes, regarding the plugin, I'm sure I did not use any of theirs. Is it a hack or something else? What's your take on this?
