Esta é a minha saída rkhunter que eu configurei recentemente para obter este relatório todas as manhãs, alguém poderia explicar por favor se eu tenho um problema sério aqui (eu sei sobre o httpd, openssl, php e sshd não atualizados, mas todos os outros comandos que eu não entendo - eu tive uma violação e alguém substituiu o arquivo por conta própria - por exemplo, '/ usr / bin / whatis')
Warning: Checking for prerequisites [ Warning ]
The file of stored file properties (rkhunter.dat) does not exist, and should be created. To do this type in 'rkhunter --propupd'.
Warning: WARNING! It is the users responsibility to ensure that when the '--propupd' option
is used, all the files on their system are known to be genuine, and installed from a
reliable source. The rkhunter '--check' option will compare the current file properties
against previously stored values, and report if any values differ. However, rkhunter
cannot determine what has caused the change, that is for the user to do.

Parece-me que você não está usando um rkhunter que é fornecido pela sua distribuição, mas baixado (o mais recente?) e instalado por conta própria, e como muitos detalhes da distribuição não foram colocados na lista de permissões, esses avisos são gerados.
Ah, eu usei o google.com btw.
