If you got an email that some files have been compromised, make sure it is not a phishing scam by calling your website host and verifying.
Forward the email to our support team firstname.lastname@example.org.
We will take the next steps to identify what has been compromised. In most cases we can restore your site from a clean backup and talk to the host about where the issue originated. In other cases, a third-party service is needed to clean the compromised files and add additional security.
