"Old is Gold" but it is not applicable for your CMS. A Number of Nepal government websites which use out-dated joomla version have been breached by a group of hackers.
The security breach was done by the group called as Msulim Cyber Sh3ll'z. The same group yesterday hacked into a number of Bangladeshi and Vietnam government website.
The list of affected sites: Nepal Law Commission(lawcommission.gov.np), deonuwakot.gov.np, www.dadokanchanpur.gov.np, Department of National Park and Wildlife Conservation(dnpwc.gov.np), Ramgram Municipality(ramgram.gov.np), nidmc.gov.np.
