About four in ten LINE users have witnessed account hijacking


When I first read the headline figure I thought it was rather high, but the text mentioned hijacking included friends’ Facebook posts promoting sunglasses, which I was seeing about once every couple of weeks last year, although it seems better recently. Anyway, this survey from the chat and SNS service LINE was into the security literacy of their members in the run-up to their “Cyber Disaster Prevention Day” on the 9th of June.

Just to fill up some space, here is a UFO Catcher full of LINE characters:
