My Website Has Been Suspended Due to Malware - Why? 列印

  • 13

Malware is short for malicious software, and represents a serious security threat to the server and visitors to your website. QiQ run Malware scans on servers from time to time and notify clients of any rogue files. If you have received a suspension notification due to Malware, this then requires your urgent attention to resolve.

We need to disable your site immediately on notification of Malware being present not only because of the security threat it presents, but in addition, Google scans websites for Malware and you may find they present you with a caution to proceeding to your content when visiting your website and blacklist your site.  As a consequence, you will not receive any visitors due to the caution, and potential future visitors will be unlikely to visit again.

Even though QiQ suspend accounts with detected Malware immediately, generally we do reactivate the site when clients confirm that either they, or their developers, are ready and able to start working on the site to eradicate any rogue files. As suspension helps prevent Google from blacklisting your site, this should be seen as a positive step in resolving this issue.

HOW COULD MALWARE BE ON MY SITE?

The most common reasons that your site has been compromised are:

a. Outdated scripts (such as Wordpress or Joomla)

b. Outdated script plugins and/or themes

c. Inappropriate file permissions

d. Insufficiently secure passwords for databases and FTP

f. XSS or SQL Injection (as a result of outdated scripts or poor code)


IN THE FIRST INSTANCE OF A MALWARE WARNING

If this is the first time a Malware warning has been given, it may be acceptable to just delete the infected file(s) and take remedial action to prevent any further infection. This would include:

a. Delete all files detailed in the Maldat warning.

b. Updating all outdated scripts (such as Wordpress or Joomla) and removing any that are not used.

c. Updating script plugins and removing any that are no longer used.

d. Correcting inappropriate file permissions.

e. Changing insufficiently secure passwords for databases, FTP and email accounts.


SIGNIFICANT OR SUBSEQUENT INSTANCES OF MALWARE WARNINGS

If we have advised previously of a Malware warning your site will be suspended and you will need to contact us to get the site reactivated so the following recommendations can be performed.

a. Backup your database

b. Download a copy of your site, but keep it separate from your clean backups.

c. Delete all files from your hosting package.

d. Contact us so that we can confirm that the hosting package is clean.

e. Change all passwords relating to the site, including database, administration, FTP, and mailboxes.

f. Rebuild your site from the latest releases of your CMS, or upload a known clean backup and update all scripts to the latest releases. If your site is custom-built, you should review the HTTP logs and vulnerable source to identify the issue, and resolve it.

g. Audit your site's security. Have you removed any installation files? Have you checked directory permissions? Have you removed any modules that are no longer required?

h. Contact us to re-enable the site.
