Verification.
WHAT TO CHECK
Your user list, for accounts you do not recognise Files modified recently that you did not change Your upload directory, for script files Your cron jobs Your site in search results
THE SEARCH CHECK
Search your domain name with unrelated terms: medication names, gambling terms, replica goods.
Injected spam pages frequently appear that way.
THE FILE DATE CHECK
Sort files by modification date in File Manager.
Anything changed recently that you did not touch deserves examination.
THE USER LIST CHECK
Attackers frequently create an administrator account.
Look for accounts you did not create.
RUN A SCAN
ImunifyAV in cPanel, or a security plugin.
CHECK FROM OUTSIDE
Load your site in a private window, on a phone, from a different network.
Some compromises show only to certain visitors.
THAT IS DELIBERATE
Redirects that exclude logged-in users, or that only affect search visitors.
