Personal details of tens of millions of Malaysians obtained from a 2014 data breach have likely been available for sale for a long time, according to the founder of an online portal who revealed the massive data breach this week.  The massive data breach, believed to affect almost the entire population of Malaysia, was first reported last month by Lowyat.net, a local technology news website. The website said it had received a tip-off that someone was trying to sell huge databases of personal information on its forums.
