WhatsApp recently patched a flaw that left 200 million users vulnerable to being hacked using booby-trapped digital cards for contact details, according to a US computer security firm.
Facebook-owned messaging application WhatsApp boasts more than 900 million users, some 200 million of them who access the service on computer browser software that mirrors activity from mobile devices.
Opening tainted cards allowed viruses to infect computers, potentially allowing hackers to steal control or information, according to an online post by Check Point computer security firm.
