whatsapp is the most famous social app for texting now a day ...all of its credit goes to it perfect data management...which beats all its opponents
attacker could perform the same by sending a very small size (approx 2KB) a message with huge set of characters ( about 2000) to the victim.
And the only thing that the victim can avoid his device from hanging or crashing is that he has to delete the whole history chat on his device
actually whatsapp has a limit for the consumption of the ram which makes it viable for the use.... now the easiest way to crash any program is to makes it loaded in such a way it weather its consumption of the memory goes beyond RAM or its parameter
we can make that happen in whatsapp by cowding a sms in such a way that its parameters are exceeded
attacker could perform the same by sending a very small size (approx 2KB) a message with huge set of characters ( about 2000) to the victim.

previously it was done with using text but whatsapp fixed the bug by putting limit of text's length
so hacker has found a new way for the crashing message
we can crash an whtasapp app by sending a text with about 4000 smilies .when it receives the text its buffer overflows and the app crashes
the only way to have the app back is to delete the chat history...
