Our friends over at Social CMS Buzz and given us a heads up on a new security issue. The module “Send Announcement v0.2″ was used on a Pligg install to send out spam emails to all the members.

There are no details as to how this happened, but it is for certain that this module was the culprit.

Social CMS, like I, are advising you to disable and remove this module until more details can be made available.
