The text chat has been hacked; wtf is going on?

Hackers have someone managed to figure out a way to send in-game text messages to players that aren't in their squads. These text messages are in red/orange and are always sent by someone who isn't part of your actual squad. THEY ARE ALSO NOT PART OF YOUR CLUB.

I didn't save screenshots but it has already happened a bunch of times to me in-game. Usually the hackers only say one sentence or joke during the jumpmaster phase and leave your team alone for the rest of the game, but it's still unnerving because if they can communicate directly with your team who is to say that they can't cheat by also spying on your team's POV?

Here are some examples from Reddit:
