The popular chat application, WhatsApp was supposedly hacked, putting millions of users under risk. A security bug in the web version of the application made it easy for hackers to include malicious codes in vCards which contain contact information.
It was so easy for hackers that they wouldn’t even require any hacking tools. All they need to do was to send a malicious vCard to a target’s phone. Such cards, when opened could infect computers, allowing hackers to steal information.
WhatsApp had only recently announced that they have reached 900 million users. This vulnerability was reported to Whatsapp on August 21st and they got it fixed on August 27. But it was made public only on 8th September.
