Endesa is the largest electric utility company in Spain. Recently it has been discovered a ransomware campaign using a fake invoice of a huge amount to pay, in order to trick users to verify it. A clever social engineering move.
More details and the full list of domains involved can be checked in the CSIRT-CV alert.
The interesting part of this new Ransomware campaign is that most of the domains hosting the malicious scripts are based on the popular Joomla CMS.
