Yes, you can crash your friends’ WhatsApp, both WhatsApp Web and mobile application, by sending them not any specially crafted messages, but just Smileys.

Indrajeet Bhuyan, an independent researcher, has discovered this new bug in WhatsApp that could allow anyone to crash WhatsApp remotely just by sending nearly 4000 emojis to your friends, thereby affecting up to 1 Billion users. Last year Buyan reported about crashing WhatsApp by sending them 2000 words in (2kb size) message in form of a special character which also can crash your victim WhatsApp.

WhatsApp has patched this bug by setting up limits of text sending in messages, but unfortunately, if failed to setup limits for smileys send via WhatsApp.

“In WhatsApp Web, Whatsapp allows 65500-6600 characters, but after typing about 4200-4400 smiley browser starts to slow down,” Bhuyan wrote in his blog post. “But since the limit is not yet reached so WhatsApp allows to go on inserting…when it receives it overflows the buffer and it crashes.”

The bug affects both Android and iSO versions and even the web interfaces.
