Facebook fixed a bug that shield Messenger calls from hackers

Highlights

Last month the bug was exposed by Google Project Zero researcher Natalie Silvanovich.

The last thing anyone wants in today's digital age is for anyone to be able to hack your calls and hear what you are talking about. But it looks like Facebook Messenger already allowed hackers to do that until recently when it fixed the particular bug. The bug, which was discovered by Google Project Zero researcher Natalie Silvanovich last month, allegedly affected only Android Messenger users. It does not affect iOS users being safe.

Hacker needs to initiate a call and send a unique "invisible" message, which makes them appear on your audio list. The worst thing is that they could do this even if you haven't answered the call. Though, it is not that easy as it sounds. The vulnerability is said to require specific tools, and not everyone can do it.

It has been explained that both the attacker and the victim must log in to Messenger for Android and the victim, also, must log in to Messenger through a web browser, for the hacking to take place. And on top of all this, the attacker would need permission to call the victim, which means that he must be on the victim's friend list for this.

Silvanovich added that similar bugs were found in other communication apps like Signal, Mocha, and JioChat. All of these have been patched now.

This is revealed after a few days after Facebook introduced the "Vanish Mode" on Messenger. The feature was announced almost a week ago, and yesterday it also hit Instagram. This, as the name suggests, deletes the particular message or multiple messages once you leave the chat thread.
