If you’re the kind of person that is consistently running behind on the latest software, it may be time to switch up your method.

That’s if a report from Forbes is to be believed, which indicates security vulnerabilities can allow hackers to access your device by sending you a single iMessage. The bug is found in almost every version of Apple’s iOS and OS X, except the latest updates.

The discovery was initially made by a researcher from Cisco, finding that a potential hacker could send a .TIF file (a simple photo file) that, once sent, can give away your device’s internal storage and stored passwords.

Here’s how to avoid the potential hacking doom: update your device to the latest version, iOS 9.3.3 or El Capitan 10.11.6.

Or, if you simply can’t bear the thought of being up to date, just turn off iMessage.
