WhatsApp/Signal Surveillance through Emoji Reactions

The video shows how emoji reactions on WhatsApp and Signal, like a heart, can be exploited to monitor users without accessing message content. By observing the timing of reactions and network activity, an attacker can infer when someone is online, when they read a message, and how often they check their phone. This side-channel attack works even with end-to-end encryption, highlighting how metadata can leak sensitive behavioral patterns.
