Without doing so, Daniel Zappala, a computer science professor who worked on the study, told that 'a clever hacker could make you think that you are encrypting your messages to your partner (let's call her Alice), when in reality, you are encrypting your messages for an intruder (let's call her Trudy).'

The process allows users to confirm the identify of their intended conversation partner and makes sure no other third party can trick you into revealing the contents of your messages.

'It is possible that a malicious third party or man-in-the middle attacker can eavesdrop on their conversations,' said Brigham Young University computer science PhD student Elham Vaziripour, who led the recent study.įacebook messenger doesn't offer automatic encryption but allows users to set it up themselves.
