Official French Defense Subdomain hacked and defaced

The official French ministry of defense website has come under attack and as a result one of its sub domains has been left defaced.
The attack comes from @HBVirus1 who first announced the defacement about 12 hrs ago on twitter.

The breached site which has been left defaced is a subdomain dedicated to the (translated) “1 ^st Parachute Regiment of Chasseurs” and appears to be effecting the complete site as no other pages are accessible,

At time of publishing the defacement was still live and HBVirus1 has stated that they did it in revenge.
A mirror of the defacement can be found on zone-h.org.
