If you see some changes that are not made by you, it can be a sign that intruders have access to your website backend.You can check manually recently modified files in WordPress:
Login into your server using an FTP client or SSH terminal.If you are using SSH, you can check all modified files list in the last 15 days using this command:
$ find ./ -type f -mtime -15
If you are using SFTP, see the last modified date column for all files on the server.Note any files that have been recently modified.Check modified all files using terminal commands on Linux:
$ find /etc -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r .
If you want to see directory files, type in your terminal:
$ find /etc -printf '%TY-%Tm-%Td %TT %p\n' | sort -r .
Unfamiliar modifications in the last 7-30 days may be suspicious.
Hosting provider suspension
