Drupal has warned of a critical vulnerability in its Drupal 7 software, for which it issued a patch. If your website manager was unable to apply this patch immediately following the initial security advisory on 15 October 2014, Drupal’s advice is to assume your site has been compromised. Hackers began automatically attacking unpatched versions within hours of the issued advisory.

Drupal is a website Content Management System (CMS) used by millions of websites worldwide to manage webpages, text, images and other content.

Drupal issued an additional security advisory on 29 October outlining the attacks and recovery options in more detail. Drupal added that the attackers may have copied the data from your site, or that your site could be controlled by the attackers and used for other malicious activities.

You may not know your site has been compromised. It is possible for the attackers to create ‘backdoors’ or access points on your system, which can later be used to gain access to your site and data, after the patch has been applied—without your knowledge.

If you or your business has a website using the Drupal CMS, you should take immediate action to apply the patch and then evaluate further mitigation options. This could include restoring or rebuilding the site, forensic investigation, notification of the incident to associated parties and users, and other actions which will depend on your site and its function. Drupal’s advisory includes some recovery advice for this breach.

Drupal’s website also offers more general advice on recovering from a breach.
