Apache входит в Debian GNU/Linux и показывает исполняемые файлы Windows

Я использую logwatch для просмотра журналов моего сервера. Это показано в разделе журнала httpd:

19033 Windows executable files (502.53 MB)

Это сервер Debian GNU/Linux. Так что это не должно быть никаких исполняемых файлов Windows. Я не мог найти ни того, ни другого. Это какая-то путаница или мне чего-то не хватает?

Все, что я мог найти в журналах, это следующие строки:

Просто "кто-то" пытался получить доступ к этим файлам через URL. На самом деле, это, вероятно, автоматический скрипт, который ищет полезные эксплойты.

Хотя этот конкретный запрос явно предназначен для систем Windows, я предлагаю вам установить и настроить модуль Apache mod_security перехватывать и блокировать эти запросы (и те, которые нацелены на систему linux, тоже!).

На самом деле, что странно, что logwatch говорит 19033 файлов, что, кажется, не соответствует вашим журналам.

Кроме того, для 404/500 и аналогичных ошибок следует сообщать что-то вроде:

--------------------- httpd Begin ------------------------ 

Requests with error response codes
404 Not Found
   /favicon.ico: 2 Time(s) 
500 Internal Server Error
   /: 1 Time(s)
---------------------- httpd End -------------------------

Может быть logwatch интерпретирует как исполняемые файлы Windows другое расширение и не только .exe файлы.
