Вирус на форуме IP.Board

Posted 1 марта, 201212 yr

Итак, недавно наш форум столкнулся с фреймом, который антивирусы посчитали за вирусную ссылку. Так как это мой первый опыт с вирусом на сайте/форуме, то я его обнаружил не так быстро, как мне хотелось..

Поделюс опытом удаления 'плохого' скрипта с форума.

Как работал фрейм? Очень просто, при загрузке страницы, подгружающей заражённый яваскрипт, он активировался при малейшем движении курсором мышки и подгружал яваскрипт с какого-то постороннего сайта, в моём случае это был ___constructivehell.is-a-cubicle-slave.com/g/1351559130384.js, что делает этот срипт - не известно.

Названиние подгружаемого скрипта генерировалось автоматически.

Первое, что пришло мне на ум - сделать резервную копию форума и слить её на компьютер, а там уже разными прогами искать вирус по тексту в файлах.... Что я и сделал. Скачав копию форума, я начал искать название ссылки, которую блокировал антивирус, во всей копии с помощью программы Folder Find Text, но все мои попытки были напрасными.. Ссылка не находилась.

Тогда я обратился хостеру, который подсказал мне где может находиться вирус и как его обнаружить (золотой же человек мой хостер )

То, что вирусный код содержится в яваскриптах, он сказал однозначно и уверенно.

Как же мне найти этот код? Было предложено отсортировать файлы по дате изменения и уже смотреть их.. Но я пошёл другим путём, поискал в интрнете подобный случай и обнаружил, что это код кодируется в скриптах. Там же я обнаружил как именно он кодируется, и, по небольшому кусочку кода, начал поиск по резервной копии..

Результаты поиска меня просто шокировали: около 200 яваскриптов было заражено этим кодом. Вот как он выглядит в зашифрованном виде:

Пришлось очищать каждый скрипт от этого кода. У меня сразу же возникло пару вопросов: Как он мог проникнуть в скрипты на сервере? Кто его туда записал?


По моему [u]не профессиональному[/u] мнению, я могу лишь предположить, что у меня просто угнали данные для доступа к FTP,  что можно проверить по логам, было ли там копирование, а затем замена практически всех яваскриптов на форуме...

Сталкивался много раз с этой проблемой на булке, но до этого момента, кстати, не замечал, что бы на IPB было похожее.

Касперыч мой ругался на вирусяку и не давал её загрузиться в браузере.

Картинко:

Данный зверюга ворует ваши пароли, хранящиеся в памяти браузера, не важно когда вы их ввели или сохранили в памяти браузера.

Скрипт заливается очень просто (как это было с булкой) просто создаётся новый юзер "с скрытыми символами" XSS атака, а также сообщением или картинкой.

Бороться можно. Достаточно ограничить доступ к файлам и папкам (непосредственно на фтп выдать нужные права для файлов - ТОЛЬКО ЧТЕНИЕ)

Ну или некоторые мои знакомые писали скрипты, которые каждый час проверяли изменение файлов на фтп Так тоже можно ^^

И кстати, Паш, настрой права у моей группы Я в чате писать не могу :D

Если у кого возникла такая же проблема с сайтами, могу скинуть скрипт, который автоматом удалит вирус из всех яваскриптов..

PS: была обнаружена другая модификация данного вируса..

похожая беда на моем форуме, изменил пароли на фтп и все остальные, удалил свой фтп клиент, запретил браузеру хранить пароли, перезалил все файлы форума и дополнений. но всёже иногда попадаеться постороний код в конце js файлов (видимо какието устаревшие файлы от старых версий форума).

но код у меня был другой, кажеться начинался с try, если опять встречу, выложу.

в логах фтп нашел этот ip: 62.122.79.1

скиньте плз скрипт и какие права на папки и файлы лучше поставить так чтобы потом небыло проблем в работе форума.

Выкладывай, посмотрим что у тебя за код..


Права изменять бесполезно - злоумышленник при внедрении вредоносного кода имеет доступ к файлам через FTP.

возможно это оффтоп, поэтому заранее извеняюсь

заметил что при редактировании сообщений на форуме не загружаеться редактор, я думал это связано с вирусом но вот и на вешем форуме также не загружаеться (вернее загружаеться но не всегда)

Установите вот это дополнение для Firefox и вы будете видеть весь JS код форума, уже в нормальном, а не в обфусцированном виде.

Выкладывай, посмотрим что у тебя за код..

Права изменять бесполезно - злоумышленник при внедрении вредоносного кода имеет доступ к файлам через FTP.

Как воспользоваться этим скриптом?

Прочитать комментарии в скрипте, что-то подредактировать согласно комментариям и обратиться к скрипту из адресной строки.

А в каком формате его сохранить нужно? ".js" ?

Я если честно вообще не разбираюсь в кодах... Вы можете подсказать что отредактировать нужно? Я вот могу скопировать и сохранить в формате ПХП но дальше я вообще не бум бум что делать...

(первый параметр — стартовая директория поиска, второй — тип файлов, участвующих в поиске, третий — строка поиска)

Пример:

В самый низ добавляешь:



$ipbmafia = new dScaner;

$ipbmafia->find('./', '.js', 'Array');


  $ipbmafia->scan('./', '.js', '=Array.prototype.slice.call(arguments).join(""),');

[/CODE]

У тебя будут свои значения. Если искомый текст будет обнаружен, то сканнер выведет эти файлы на экран.

Для исключения вирусов, я б конечно хотел снести весь форум к ядреной бабушке, и файлы с базой восстановить на свежей четверке.

Это правильно! Думаю, лучше переустановить на чистую 3-ку а затем обновить до 4-ки.
