The researchers have also mentioned the consequences of this flaw in their blog post as, "This means that attackers could potentially download your photos and or post them online, send messages on your behalf, demand ransom, and even take over your friends' accounts,"

This security firm says hackers were able to access WhatsApp user accounts by sending a photo file containing malicious code inside it. If the web user clicks on the photo, the hacker will be granted with full access to attack that particular account.

A similar concept has been used in the Telegram hack where hackers send a video file having malicious code to the web user.

This malicious code could hijack such accounts and spread itself by sending virus infected messages to others in the contact list.
