Eavesdropping
Eavesdropping is when a third party listens to and possibly copies or records the messages being exchanged over a network in real-time. A typical example is when passwords to social media accounts are stolen when the user is connected to a public WiFi. Another example is someone at a different location listening in on your call or looking at your messages as they are being exchanged.
Leading social media companies use end-to-end encryption to protect their users’ calls and messages and combat eavesdropping.
