Linux Server hackeado? [duplicado]

5

Estou tentando determinar se esse servidor linex webserver / openfire foi comprometido por algum tipo de malware ou hacker. Você pode, por favor, me ajudar a determinar se esse servidor foi invadido?

O trecho de logs abaixo é do servidor linux executando o apache. Há poucos dias o site moodle, que está instalado no servidor, começou a renderizar a página default do apache. Além disso, os registros de acesso mostram alguma atividade que eu não tenho certeza. Por favor, veja os logs abaixo.

O snippet de log mostra muitas atividade de varredura para ver se o seu servidor web atuará como um proxy aberto. Eles estão falhando (todos esses resultados 403, 404 e 405), então isso é bom.

A atividade de varredura é um ruído de fundo normal. A atividade de digitalização que está encontrando coisas não é.
