Вирус js как найти и удалить
Примерно 30% обращений наших клиентов связано с этой проблемой.
В этой статье мы расскажем, как успешно найти и удалить вредоносный js вирус с сайта.
Js вирусы – вредоносный Javascript код внедряемый хакером в файлы вашего сайта.
Как следует из названия изменению и заражению подвергаются файлы с расширением *.js
Антивирусные компании насчитывают тысячи модификаций, еще больше остается незамеченными и появляются каждый день. Разные названия, разные цели.
Содержание:
Где искать?
Внедряемый код может быть разный, как правило предварительно шифруется, для усложнения отладки и определения.
Но есть несколько характерных признаков. Как правило js вирус:
1) дописывается в конец существующего кода.
2) дописывается в начало существующего кода.
Исходя из этого поиск необходимо делать как в js так и php файлах.
Что искать?
Проверку начинаем с просмотра исходного кода страницы на которую есть подозрение.
Ищем “включения” – ссылки ведущие на сторонние сайты.
Если вирусная ссылка находится, проверяем ее наличие во всех файлах вашего сайта.
Часто js вирусы используются для перенаправления посетителей сайта, по заданному типу браузера или операционной системы, поэтому следует проверить наличие слов:
refferer, yandex, google, user-agent
В php файлах возможно добавление кода вида:
eval(base64_decode(. ));
Найдя один образец вируса, следует проверить его наличие во всех файлах сайта.
Если ни один из приведенных шаблонов поиска не подходит, можно сравнить любой из js файлов на сайте с оригинальным кодом. Для этих целей подойдут часто используемые библиотеки. К примеру jquery.
Сравнив 2 файла можно найти вставки и модификации, которые необходимо удалить.
Как удалить?
Перед проведением работ, следует поменять все пароли доступа к сайту и сделать резервную копию.
К сожалению зараженных js файлов может быть не один десяток. Иногда счет идет на сотни. Вариантов решения как всегда несколько:
1) Самый простой – восстановить файлы из резервной копии (если она есть).
2) Написать небольшую программу, которая по заданному шаблону проверит все файлы и удалит ненужный код.
3) Воспользоваться программами для автоматического поиска и замены текста.
Как защититься?
Следует помнить, что js вирусы на вашем сайте появились не просто так. Мы устранили следствие взлома, но не причину. Это значит, что ситуация может повториться в любой момент.
Общая рекомендация: установка последних версий используемого программного обеспечения, включая основную систему, используемые плагины и дополнительные компоненты.
Как определить причину, отдельная тема, не укладывающаяся в рамки небольшой заметки. В любом случае, если вы дорожите своим сайтом и своими клиентами (а мы своих очень любим), желательно обратиться к помощи специалистов.
Мы всегда будим рады вам помочь.
