A Backdoor (/Bug?) in WhatsApp
From 33C3_Public_Wiki
| Description | I demonstrate that the WhatsApp client on Android automatically retransmits messages and encrypts them with newly announced public keys without user interaction. This makes it possible for WhatsApp to snoop on selected messages. WhatsApp is aware of this bug(?) since before April 2016 and did not fix it. |
