Thank you for patience and cooperating with us. Let us clarify that
hackers are using "write" permissions opened on the web server for
overwriting hosted data. It is not secure to have permission for the
folders set to 777 or 775 as it allows everybody to do everything to
this file. Having files/folders with such permissions anyone can write
to it. This means a security hole since everybody on the server can
overwrite these files or can write, remove or overwrite files in the
directories.
(777 is a read permissions for owner, group and others; write
permissions for owner, group and others; execute permissions for owner,
group and others;). You should check all files/folders found in your
account and set permissions for folders chmod 755, files 644.
Please, review listed files/folders in a ./permissions.list file
created under the FTP directory. Please, fix permissions a soon as
possible to block this hole in security.
We suggest you to look into this problem deeper, to learn more about
what you can do to protect yourself in the future, or how your site may
have been compromised in the first place, please follow these links:
