These responses only contain half of the answer. There are generally 2 ways to embed a virus into an office document.
Macros:
Macros are snippets of Visual basic code generally containing functions that can enhance the document maybe for complex counting or auto filling or many other reasons. Macros can do a lot like download files from the internet, and install trojans or other viruses. Macros sometimes require you to click a button or «enable» them before they’ll execute but this can depend on your security settings. You should never trust macros from the internet without understanding them at a basic level, the best advice is to disable macros and enable them on a case by case basis.
Exploits:
The other way documents can contain viruses is via exploits, software exploits are generally due to an error made during the development of the program and once discovered are often patched. Exploits are often stored in saved files like word documents or excel sheets. Exploits are made up of 2 parts, the actual exploit and the payload what happens when word for example opens a file containing an exploit is the document looks normal until a certain bit where it may contain something more complex like a shape, in word 2003 there was an exploit in the shape processor where crafted shape data would allow code in the remaining of the document to execute and install pretty much anything it wants, a common technique is code that downloads more virus files from the internet and then starts sending information about your computer back to the attacker, they will often receive your keystrokes, maybe passwords or they might try and inject code into websites you visit making you transfer money without your knowledge. There are ways to combat exploits though. If you can you should use some exploit mitigation software like emet but your antivirus may do exploit mitigation also. The second thing you can do arguably more important than the first is keep all your software up to date. As exploits get discovered, developers will update their applications to not be affected. So it is important to keep things updated and be suspicious of files sent to you from unknown sources.

Zip File, мамкины хацкеры. Сегодня я расскажу вам, как злоумышленники прячут ссылки на вредоносное программное обеспечение и фишинговые сайты прямо в word’овских документах. Данный метод маскировки настолько хорош, что может поставить в тупик, даже прожжённого офисного планктона. Его очень часто используют при распространении палёных курсов и тренингов.
Да-да, те самые книги и руководства про успешный успех от нелюбимых вами инфоцыган, в лёгкую могут таить под капотом реальную угрозу для вашей безопасности. Особенно если качаете вы это добро с какого-нибудь сливапа или только что созданного паблика в телеграме. Тут вероятность нарваться на дерьмецо возрастает в разы.
Что ж, друзья, думаю суть понятна. Давайте нынче не будем долго запрягать и сразу перейдём к практике. А то мне ещё утром на участок надо бежать, поправки путинские принимать. Вбрасывать там, фальсифицировать. Ну вы знаете, всё как обычно. Мы там это, с колен вроде как встаём, так что низя опаздывать. Уж не обессудьте за столь лаконичное вступление. Погнали.
Шаг 1. Создаём на рабочем столе новый вордовский документ. Так и назову его – гавнокурс, чтобы все инфоцыгане, включая вашего покорного слугу, обладающего самоиронией, были довольны.
Шаг 2. Открыв док переходим на вкладку «Вставка» и ищем пункт интеграции «Видео из интернета». В открывшемся окне вводим для примера название youtube-канала и кликаем по иконке поиска.
Шаг 3. Вставлю для демонстрации рандомное видео со своего проекта.
Шаг 4. Отлично. Видос в файле. Примерно так их вставляют в качестве доп. материалов к основной статье различные интернет-гуру. Теперь можно закрывать документ, не забывая при этом сохранить изменения.
Шаг 5. Далее запускаем WinRAR и вызвав контекстное меню вордовского файла, переходим к его внутреннему содержимому.
Шаг 6. Нас интересует файлик «document.xml». Он содержит в себе дополнительные настройки для текста и, собственно, сам текст нашего документа. Вытаскиваем его на рабочий стол
Шаг 7. И открыв в нотпаде или блокноте ищем строчку со ссылкой на youtube-видео. Вот она.
Шаг 8. Ну а дальше, мы вольны творить что душе угодно. Давайте, забавы ради встроим код логгера для выяснения местоположения и IP-адреса потенциальной жертвы. Для этого заходим на iplogger.org и вставляем любую ссылку в первое окно. Жмём «получить код».
Шаг 9. Копируем получившуюся ссылку для сбора IP в буфер обмена.
Шаг 10. И вставляем её вместо ссылки на видео в нашем XML-файле.
Шаг 11. После внесения изменений закрываем редактор файла с последующим сохранением.
Шаг 12. И возвращаем его на место закинув в окно WinRAR’a. Окей.
Шаг 13. Давайте проверим, что же мы намудрили. Открываем гавнокурс и подводим ползунок к видосу. Программа показывает, что при нажатии, будет запущен видеоролик с ютуба. Ничего подозрительного. Уверяю, 88% юзверей даже не почуют подвоха.
Шаг 14. Однако при открытии, вместо долгожданного видео, на экране выскакивает ошибка. Тут человек, как правило думает, что мол, ну и ладно. Подумаешь видос не работает, главное книжку скачал на халяву.
Шаг 15. Мы же, тем временем, можем вернуться на сайт iplogger и в разделе «Статистика посещений», посмотреть IP-адрес с которого была зафиксирована попытка просмотра.
Шаг 16. Также тут можно прочекать геолокацию, вплоть до дома.
И это, ещё самое безобидное, что можно было внедрить. Вы ведь помните, я тут не армию злоумышленников выращиваю, а объясняю основы инфосека в обучающих целях для понимающей аудитории. Но настоящий блэк хэт будет вставлять далеко не безобидный логгер для выяснения вашего адреса. Он встроит ратник, вирусную программу или какого-нибудь хитро вые***ый java-script.
Данная фиха работает в пакетах MSOffice, начиная с версии 2013 года. И в данный момент, её до сих пор не пофиксили. Я специально скачал для записи самый последний апдейт, дабы убедиться в проверке функционала. И да, я дико извиняюсь за кликбейт, но вы порой правда просите сделать очень узкие темы, которые в интернете никому на*уй не сдались. Поэтому приходится как-то выкручиваться и перефразировать.
Однако, уверяю вас, это сделано умышленно и даже банальное знание IP-адреса может сыграть на руку грамотному пентестеру. Так, в следующем видео, я покажу, как зная внешний IP-адрес роутера, можно провести по нему полноценную DDoS-атаку. Но эт только если соберёте 500 лайков под этим роликом. Денчику нужны ваши лойсы. А ещё я коллекционирую души в виде подписок. Так что если ты, друг мой впервые забрёл на канал, то не тупи а.
Кликай на грёбаный колокол и в твоей ленте регулярно будут появляться годнейшие гайды на тему этичных взломов, пентестинга и самой что ни на есть информационной безопасности. С олдов по традиции, жду комментарии, касательно того, что бы вы встроили в такой документ, перейди вы, чисто теоретически на тёмную сторону. Мне будет весьма интересно узнать, чего же вы жаждите на самом деле.
Ну а у меня на сегодня всё. В заключении, хочу пожелать вам удачи, успеха и самое главное безопасного обучения. Берегите себя и свои тачки, скачивайте материалы только на официальных сайтах инфоцыган и никогда не попадайтесь на такие уловки. Помните, что халявный сыр – бывает только в мышеловке. А за всё, действительно годное и крутое – приходится платить либо временем, либо рублём, либо дважды. С вами, как обычно, был Денчик. До новых встреч, камрады. Всем пока.

На самом деле правильнее было бы назвать эту статью «Как хакеры скрывают вирусы в документах Office а Microsoft на это наплевать» Но давайте по порядку.
В последних версиях Microsoft Office по умолчанию документы сохраняются в формате, основанном на Office Open XML, но Microsoft не во всем следует открытому стандарту. Вариант Microsoft часто называют MOX, Microsoft Open XML. Этот самый MOX имеет уязвимости, создающие угрозы безопасности. В этой статье мы подробно разберем одну из таких дыр, которая на момент статьи так и не закрыта.
Еще по теме: Лучшие сайты для поиска уязвимостей
Почти сразу после публикации чернового варианта OOXML началась битва за его стандартизацию. Вот краткая хронология версий.
В 2016 году были выпущены дополнения к 5-ой версии: ISO/IEC 29500-1:2016 и ISO/IEC 29500-4:2016. Работа над стандартом продолжается, а компания Microsoft допускает все больше проприетарных особенностей его реализации в последних версиях Office. Хуже того: Microsoft не признает старые уязвимости, оставляя их в новых версиях. Вы не поверите, но описываемая в данной статье уязвимость известна с Office 2013 и актуальна вплоть до Office 2019.
ECMA-376 включает в себя три различные спецификации для каждого из трех основных типов документов Office — WordprocessingML для текстовых документов, SpreadsheetML для электронных таблиц и PresentationML для презентаций. Мы будем использовать WordprocessingML.
Я возьму на себя смелость указать на два критичных с точки зрения безопасности недостатка MOX, унаследованных от OOXML:
- возможность легкого редактирования внутренней структуры документов;
- отсутствие проверок на злонамеренную модификацию.
По сути, MOX и OOXML — это XML в ZIP. Это отличный hacker-friendly-формат, поскольку найти и заменить свойства объектов в нем исключительно просто даже без использования HEX-редакторов и прочих специфических утилит. Достаточно встроенной в Windows поддержки ZIP и «Блокнота». Весь код легко читается глазами и правится, как текст. Ни сверки контрольных сумм, ни каких-то иных специфических проверок при этом не выполняется. Word лишь проверяет целостность документа, которая не нарушается при подменах с соблюдением правил синтаксиса.
Если в документ вставлен объект, загружаемый с внешнего ресурса (например, ссылка на видео), то в соответствующей секции создается легко читаемая (и так же просто изменяемая) гиперссылка. Это прямая дорога к фишингу или запуску троянов в один клик.
Статья предназначена для профессиональных пентестеров, руководителей службы CISO (информационной безопасности), а так же для «белых хакеров». Ни автор статьи, ни редакция сайта spy-soft.net не несут ответственности за любой возможный вред, причиненный материалами данной статьи,
Описание уязвимости
В базе уязвимостей MITRE есть много однотипных записей вида: «Microsoft Office… do not properly validate record information during parsing of (Excel spreadsheets / Word documents, Power Point presentations)… which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted file)». Проще говоря, проблемы парсинга XML в MS Office неисчерпаемы, как атом.
Я уже рассматривал одну из них в статье «Перехват хеша с помощью документа NTLMv2-SSP». Сейчас я познакомлю вас с другой атакой, также слегка изменив внутренности Word.
Начиная с Office 2013 в OOXML стал доступен класс WebVideoProperty. Он используется в разметке при вставке в документ онлайн-видео и описывает параметры его воспроизведения через набор атрибутов.
Нас интересует атрибут embeddedHtml. Он используется для вставки сторонних объектов и содержит ссылку на них (например, на видео с YouTube). Из-за того что данный параметр «знает», откуда открывать картинку видеозаписи, его невозможно опустить при парсинге.
Поиск объекта подмены
Давайте выполним простую атаку подмены и пощупаем уязвимость своими руками. Запускаем Word (требуется версия 2013 или выше, так как нам нужна полная поддержка ISO/IEC 29500 Strict) и открываем меню «Вставка».
В появившемся окне в строчке напротив YouTube я просто вписал слово «видео» и выбрал первую понравившуюся картинку. Вставка ролика отобразилась на листе документа типичной превьюшкой.
Сохраним и закроем его. Обратите внимание, что размер файла почти не изменился. У меня он занимал несчастные килобайты. Значит, вставленное видео не сохраняется локально, а всегда запрашивается из интернета по известной ссылке.
Следующим шагом нам надо заглянуть в нутро документа. Меняем расширение .docx на .zip, открываем любым архиватором и видим содержимое.
В папке word нам нужен файл document.xml. Разархивируем и откроем его на редактирование (подойдет и простой Notepad, хотя Notepad++ намного удобнее из-за подсветки синтаксиса).
В скудной документации о классе WebVideoProperty указано, что в теле документа он именуется wp15:webVideoPr. Находим эту секцию и смотрим ее содержание.
Конструкция изначально выглядит следующим образом:
|
embeddedHtml=«<iframe id="ytplayer" src="https://www.youtube.com/embed/k85mRPqvMbE" frameborder="0" type="text/html" width="816" height="480" />» |
Атрибут embeddedHtml содержит iframe YouTube, который при замене на HTML или JavaScript будет выполняться. А это не что иное, как уязвимость!
Эксплуатация уязвимости
Если внимательно посмотреть на содержимое секции, то можно заметить, что символы < и > заменены на < и >. Это способ записи символьных данных без использования раздела CDATA. Они указывают парсеру на то, что эта часть документа не содержит разметки. Так же мы должны поступить со всеми нашими спецсимволами.
Еще стоит отметить, что все параметры отделены друг от друга точкой с запятой. Если мы пропустим хотя бы одну из них, то при открытии документа произойдет ошибка проверки целостности файла. Правда, Word облегчает задачу, подсказывая, где именно мы ошиблись (см. скриншот).
Давайте удалим все, что находится между кавычками, и попробуем вставить свой HTML-код. Сначала добавим отображаемую часть ссылки:
В нашем случае она будет выглядеть следующим образом:
|
embeddedHtml=«<H1>Хакер</H1>» |
Теперь подменим исходную ссылку на ролик с YouTube своей. Например, загрузим какой-нибудь файл на компьютер жертвы.
В качестве «вредоносного сервера» я поднял дистрибутив Ubuntu 16.4 с Apache2 и положил в каталог /var/www/html два файла: условного зловреда и простую HTML-страницу со ссылкой на него. IP-адрес сервера в локальной сети — 192.168.1.20.
Далее нам необходимо все это указать в embeddedHtml:
|
embeddedHtml=«<a href="http://192.168.1.20/1.html" frameborder="0" type="text/html" width="816" height="480" >Xакер</a>» h=«480» w=«816» |
Теперь сохраним наш измененный файл и запустим его.
Для первой проверки я подготовил имитацию жертвы — компьютер с Windows 10 (1803) и MS Office 2016 Professional Plus VL x86, который мы и будем атаковать.
После запуска файла не видно ничего необычного. Открывается документ со вставленным видеороликом. При наведении курсора отображается корректная ссылка на него. Но, если нажать на воспроизведение, вместо видео отобразится наша ссылка.
В реальном сценарии вместо хакер лучше написать что-то более подходящее для фишинга. Например, Click to begin playback.
Может быть, со времен Office 2016 уязвимость уже пофиксили? Давайте проверим, сработает ли этот способ в Microsoft Office Pro Plus 2019 и Windows 10 (1803).
Открываем тот же файл и пробуем запустить видео. Слово «хакер» так же подчеркнуто и выступает в качестве ссылки. При клике на него открывается браузер Edge с нашей страницей на «злом сервере». На ней все та же ссылка для загрузки зловреда.
Примечания
Стоит уточнить ряд важных моментов. Трюк работает, если пользователь просто нажимает левой клавишей мыши на кнопку Play в превьюшке вставленного в документ видео. Так делает большинство, но продвинутые могут кликнуть с зажатой клавишей Ctrl. В этом случае начнется воспроизведение видео.
Почему так происходит?
При нажатии левой кнопки мыши с клавишей Ctrl и без нее Word обращается к разным секциям документа. В первом случае он считывает подмененную ссылку из worddocument.xml и предлагает выполнить переход по ней. Во втором — считывает оригинальную ссылку на видеоролик из word_relsdocument.xml.rels и запускает его.
Если же подменить адрес в обеих секциях, фишинговая ссылка будет отображаться при наведении курсора мыши на превь ролика. Такой грубый вариант атаки сработает только с самыми невнимательными пользователями.
Также заметь, что при нажатии левой кнопкой мыши с Ctrl откроется браузер, установленный по умолчанию. Если же просто кликать, то (вредоносная) ссылка всегда будет открываться в браузере. Это еще один вектор атаки при проведении пентеста.
В зависимости от версий ОС и Office, а также настроек безопасности у жертвы могут сработать другие компоненты защиты. Например, Office 2010 ограниченно поддерживает OOXML. Он предложит разрешить редактирование документа прежде, чем позволит кликнуть на превью видео. В Windows 7 IE выдаст предупреждение при открытии ссылки.
С Windows 10 наблюдается совсем другая картина. В настройках по умолчанию (а у потенциальной жертвы они, как правило, такие) ни IE, ни Edge ни о чем не предупреждают. Ссылка открывается без дополнительных действий. Отсюда можно сделать парадоксальный вывод о том, что новая операционная система оказалась более уязвима к подобным атакам.
Для дополнительной проверки я открывал файл с измененной ссылкой в следующих офисных пакетах:
- Open Office 4.1.6;
- Libre Office 6.1.3;
- Soft Maker Office 2018.
Все они официально поддерживают OOXML, причем в точном соответствии со стандартом ISO/IEC 29500. Ни один из них не подвержен рассмотренной уязвимости, поскольку все вольности Microsoft игнорируются. Получает, что пользователь лучше защищен благодаря отсутствию поддержки проприетарной функции вставки онлайн-видео… но ведь, кроме роликов, в документы можно вставлять и другие объекты.
Выводы
В данном примере мы рассмотрели, как модифицировать XML-разметку офисных документов, чтобы выполнить подмену ссылки и подсунуть жертве зловреда. При проведении пентеста вместо пугающей надписи «Хакер» можно подобрать что-нибудь более привлекательное. Например, указать, что для воспроизведения ролика необходимо скачать плагин или обновить плеер. Красиво оформляем страницу загрузки, внушаем, что все безопасно, и дело в белой шляпе.

What is Word ransomware?
Word is a new file-locking virus that is actively spreading around the internet. It is noteworthy that Word is originated from another dangerous virus – Dharma ransomware. There are many Dharma virus variants and despite the difference in encryption algorithms, they all have a common goal – block access to user sensitive data and then demand money for a decryption key. Within encryption, it can also delete shadow copies of files and system restore points making file recovery almost impossible. Nonetheless, we are unable to recommend you to pay ransom for the decryption of your files, because there are no guarantees that they send you a decryption tool. In this article, you will find instructions on how to remove Word ransomware and decrypt .word files.
Crysis/Dharma family group
As we mentioned earlier, the virus affects data in such a way so you won’t be able to open files with .id-xxxxxxxx.[vm1iqzi@aol.com].word extension unless they are decrypted. Here, Word ransomware displays a pop-up window and creates FILES ENCRYPTED.txt file. Cybercriminals urge users to contact them via email to know the ransom amount and solve the problem as soon as possible. As usual, cybercriminals offer free decryption of several files to prove that they can really decrypt the victim’s files. Typically, such virus programs encrypt data securely enough so that you have no choice but to purchase decryption tools from cybercriminals. Regular backups will save you from these problems. It is worth noting that the files remain encrypted even after the removal of the ransomware, its deletion only prevents further encryption.
The content of the pop-up window:
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail vm1iqzi@aol.com
Write this ID in the title of your message –
In case of no answer in 24 hours write us to these e-mails:vm1iqzi@aol.com
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as a guarantee
Before paying you can send us up to 5 files for free decryption. The total size of files must be less than 10Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click ‘Buy bitcoins’, and select the seller by payment method and price.

How to decrypt files infected by Word Ransomware?
Most regrettably, there are no free decryption tools that will be able to decrypt files encrypted by any Dharma Ransomware variants. All of the methods listed below do not guarantee full file recovery. Nevertheless, due to the lack of other ways than to pay the ransom, we advise you to perform them, maybe they will help at least partially restore your data.
Method 1. Restore your files with the help of Recovery Tool
In case your PC has been attacked by ransomware, you may restore your files by using file recovery software. Stellar Data Recovery is one of the most effective tools that can recover lost and corrupted files — documents, emails, pictures, videos, audio files, and more — on any Windows device.

-
- Once the scanning process is done, click Recover to restore your files.
-
- After this, select a destination and click Start Saving to save restored data.
Since new ransomware-type viruses appear almost every day, there is no technical possibility to issue a decryptor for each virus. In this case, the recovery tool comes to the rescue. Despite the fact that this is one of the most effective methods in the absence of a decryptor, this is not 100 percent and not the only way.
Method 2. Restore the system using System Restore
Although the latest versions of Word Ransomware can remove system restore files, this method may help you partially restore your files. Give it a try and use standard System Restore to revive your data. The entire process is preferably carried out in Safe Mode with Command Prompt:
For Windows XP/Vista/7 users:
Restart your computer and before your system starts – hit F8 several times. This will prevent system from loading and will show Advanced boot options screen. Choose Safe mode with Command Prompt option from the options list using up and down arrows on your keyboard and hit Enter.
For Windows 8/10 users:
-
- Click the Start button, then select Settings
- Click Update & Security, then select Recovery and click Restart now.
- After your device reboots, go to Troubleshoot > Advanced options >Startup Settings > Restart
- After your PC restarts, you should press F5 key to Enable Safe Mode with Command Prompt.
After the system is loaded in Safe Mode with Command Prompt, do following:
-
- In the Command Prompt window, type cd restore and hit Enter.
-
- Then type rstrui.exe and hit Enter again.
-
- Once a new window shows up, click Next.
-
- Choose the date before the infection appearance and click Next again
-
- In the opened pop-up window, click Yes to start system restore.
Method 4. Roll the files back to the previous version
Previous versions can be copies of files and folders created by Windows Backup (if it is active) or copies of files and folders created by System Restore. You can use this feature to restore files and folders that you accidentally modified or deleted, or that were damaged. This feature is available in Windows 7 and later versions.
- Click the encrypted file and choose Properties
- Open the Previous Version tab
- Select the latest version and click Copy
- Click Restore
How to prevent your system from Ransomware?
No one is safe from infection with a virus that secretly encrypts your data. But in order to minimize this risk, you need to follow the rules:
1. Always make Windows updates on time and keep them up to date. Remember that these updates close the security holes in the system through which the virus can enter your computer.
2. The most efficient way to avoid data loss is of course to make a backup of all important data from your computer. It is enough just to synchronize the necessary folders with one of the cloud services, so as not to be afraid to see the text requiring the payment of bitcoins in exchange for a decryption key. It can be a cloud or a remote hard drive on the network. If you store all your files on the Internet, the likelihood of virus infection will be lower. Do not make copies to external hard drives, as this could damage them.
3. Since spam email is the most popular form of spreading ransomware-type viruses, the user should never open email attachments without first having scanned them with antivirus. Just clicking on the link or opening the attachment can damage the operating system (Windows) in a few minutes, damage important data and infect other machines with the virus.
4. All previous methods do not matter if you do not have a reliable antivirus. The presence of anti-virus protection on your computer can prevent all these unpleasant surprises. Anti-virus protection will protect you from malware, money loss, time loss, invasion of your personal life. Now the antivirus protection is so huge that it is difficult to make a choice in favor of one of them. If you have not decided who to give preference to, we suggest you familiarize yourself with our Top 5 Antivirus Software for Windows

Word Ransomware
Ransomware called Word is a new strain of the well-known Dharma cryptovirus. As a ransomware program, Word corrupts computer operating systems and then reaches valuable personal files. As an end goal, Word ransomware has to blackmail its victims into paying a hefty ransom fee to hackers.
An infection with this ransomware will prevent you from opening important files. They will be all marked with the .word extension. Since their code is transformed by a strong cipher, they can be decrypted only with a special key that will revert back the code to its original phase.
You will be presented with two ransom notes that request a ransom payment. Our advice is to skip following hackers’ instructions as they guarantee nothing. Instead, see how to remove the Word virus from your PC and try to restore .word files with some alternative methods.

More Details About Word Virus Attack
An attack with the nasty Word virus begins the moment its payload file loads on a computer system. This file tends to land on target systems via shady methods like spam emails with malicious attachments, hacked sites, software cracks, fake software updates, freeware with compromised installers, and others.
Word virus’ access to your machine will enable it to run a long sequence of malicious changes. Those changes will happen in the background of all other running apps. The ransomware program is developed to compromise basic security settings.
Then it becomes able to reach target files and encrypts their code. For the encryption, it uses a sophisticated cipher algorithm. Word virus may encode personal files of all types.
- Audio files.
- Video files.
- Document files.
- Image files.
- Backup files.
- Banking credentials, etc.
Files encrypted by Word ransomware can easily be spotted as they all have three unusual extensions. Their original names will be followed by an ID number, a hackers’ email address, and the extension .word.
It became clear that Word is a cryptovirus based on the infamous Dharma/CrySiS ransomware code. It has lots of predecessors with various strange names such as 2021, Fresh, and WSHLP. The main differences are the extensions they use to mark corrupted files and the cybercriminals’ email address. Word is controlled by fraudsters who use the email vm1iqzi@aol.com. The email helps them to communicate with their victims and extort money from them.
This email could be found in the ransom messages created by the Word virus. The main message appears as a pop-up window on PCs infected with the threat. The messages aim to trick you into buying and transferring cryptocurrency to hackers’ wallet. We know that the decryption of your .word files is of paramount importance, but we still do not recommend that you act according to hackers’ expectations.

Poster here to attract a larger audience base !
Hello all,
As my title says it all. Is that even possible? My Landlord’s computer recently had an attack from a virus called CryptoLocker. Apparently it claims that all (Excel and word) files on the computer including ones that were on a removable disk (that was connected at the time of attack) has been encrypted. It says encrypted, but technically it is not. It has just corrupted the files. Not sure how to go around fixing it. He is quiet old and does not know anything about having multiple backups. So he is at loss, so am I. I thought to give a helping hand…
The above are the two errors that come up for all the documents. The virus has been removed using multiple malware/antivirus program. Unfortunately none of the documents could be recovered.
I am trying almost everything that could be found on the internet, the only thing I have not tried is complete uninstall of the MS package. The problem is he does not have the Key to the MS office package. So reinstallation would be a pain.
I have followed most of the steps provided on:
http://www.techrepublic.com/blog/10-things/10-plus-ways-to-recover-a-corrupted-word-document/ (except for step 10, I am looking at 3rd party softwares right now)
http://office.microsoft.com/en-gb/w…text-from-a-damaged-document-HP005189610.aspx
http://support.microsoft.com/kb/918429
All proved to be in vain !
Has anyone had this kinda attack. Is there any hope for recovering?

Could you tell us what virus checker found Crypto Locker?
I read that all virus checks are not equal. I use three different ones out of total fear.
I thought that I had something too on some files I left open too often. It turned out that the wiring to my electrical outlet was faulty. The constant brown-outs that were barely noticeable on the desklamp. But, it eventually destroyed two internal PC power supplies.
The excel file with many tabs, was left open. I now close spreadsheets. They won’t open as excel. All my other excel files (that were not left open) work just fine.
I searched in vain for a solution. These were really big, detailed files.
So, if you find anything, please post it. Please.

CryptoLocker is a nasty piece of $***. The Gaurdian has covered a recent article on this issue.
Unfortunately all is lost ! It says only 3% of the victims paid the money, however it did not say how many actually got their data back.
Well one lesson to take away from this is 10 ways to beat CryptoLocker

I would not suggest any third party tool. Please peform manual operation. There are many manual operations available by Microsoft free of cost. If error still persist then you can provide answer to Social Technet forum. Here so many MVP’s will provide correct answer.
