A Vulnerability has been discovered in the wildly popular messaging app WhatsApp, which allows anyone to remotely crash WhatsApp just by sending a specially crafted message.

Two India based independent security researchers, Indrajeet Bhuyan and Saurav Kar, both 17-year old teenagers discovered the vulnerability.

With 2000 words (2kb in size) message in special character set can crash Whatsapp messenger app. Previous it was discovered that sending a huge message ( greater than 7mb in size) on Whatsapp could crash victim device and app immediately, but using this new exploit attacker only need to send a very small size (approx 2kb) message to the victim.
The worried impact of the vulnerability is that the user who received the specially crafted message will have to delete his/her whole conversation and start a fresh chat, because opening the message keeps on crashing WhatsApp unless the chat is deleted completely.

THIS VULNERABILITY ONLY WORKS IN ANDROID!!!

Here's the message to paste for the victim: http://pastebin.com/3efiBva4

Only all of Europe, since it's a cross-platform messaging system that only relies on an Internet connection. Data packages are cheap and free WiFi is abundant over here, sms/mms packages can be expensive.

i hate it though, i'm in way too many groups and therefore my phone is constantly buzzing since the threshold for sending 40 messages in an instant is non-existent.

I've tried it, didn't really see what made it that more special than ios messaging. Pretty sure you only need wifi to do that

Cross platform is the key.
