WhatsApp Web has a security bug that allows you to spy on when you connect and when you talk to someone

The WhatsApp web version may be jeopardizing data from your latest connections to the popular application, as engineered by Rob Heaton through simple lines of code.

The time you go to bed, the time you get up and even the moment you're talking to your contacts. All these data are those that the engineer Rob Heaton has been able to discover through an extension of Chrome developed by himself with simple lines of code.

At the time, WhatsApp created the option that users could remove the famous' last online ', which brings with it the elimination of double blue check, but could not remove (or did not want) the' line 'when a user is connected.

And it is precisely that 'online' that has taken advantage of Rob Heaton. The engineer developed a small extension of Chrome that sent some of his contacts to prove it. Through it, he was able to monitor the latest connections of his contacts and create relationships with the moments in which they went to sleep and woke up.

In the same way, he was also able to discover the interactions between them, applying a system of logic to discern when they were simultaneously connected and thus conversing with each other.

Although this experiment of Rob Heaton requires a certain level of computer to be able to carry out, it jumps the alarms as far as the privacy is concerned and it gives account of how vulnerable that can become WhatsApp in his version of desktop.
