According to an information we received from a friend of iGuRu.gr, one was hacked subdomains of the National Center for Research and Technological Development.
You can see the vulnerability in the URL
http://nanoredsol.apt.cperi.certh.gr/vuln.gif
The violated subdomain describes the object of the NANOREDSOL project which is the development of nanostructured materials and monolithic reactors for the utilization of solar energy for the purpose of production hydrogeny through the thermochemical decomposition of water.
Once again it is a shame to talk about technological development and not pay attention to some key points in it better safety of our systems.
