You can circumvent this by checking all messages via PlayStation.com or the PlayStation App, or setting your PSN account privacy to restrict all incoming messages. Have you or someone you know had your PS4 bricked?
This exploit works by sending a message that contains a special character in it, the message will simply arrive at your PlayStation 4 as "Juegas ⍰ ♡", it doesn't even take opening the app for the issue to occur as you'll find your system locking up before hard crashing. During the game, the team members were booted out of the game, after receiving a message on the PlayStation Network with an unrecognised character.
For example, a gamer with the username Huntstark1 described a situation they encountered as their team was involved in a match-up of Rainbow Six: Siege.More news: Sox beat Yankees 4-3, advance to ALCS
From a web browser, visit the PSN Privacy setting page, then sign in with your PS4 account credentials. Once the message is opened the PS4 crashes and users typically have to start in Safe Mode and rebuild the database. All it takes is to keep your messages is to set your messages to private, meaning you can either only receive messages from registered friends or no one at all. We're not totally clued up on the technical details yet, but the bottom line is that right now, a factory reset of your PS4 - which deletes all of your data - is the only guaranteed way to get your console up and running again.
Kotaku has reached out to Sony for comment but they did not respond in time for publication.
So if your messaging settings currently allow you to receive messages from strangers, you may want to change them for now.
