Are you concerned about zero-click exploits on your iPhone or Android device?

The National Security Agency (NSA) has a simple yet effective piece of advice: turn your device off and on again once a week.

This routine reboot can help protect against zero-click exploits that allow attackers to eavesdrop and gather data without user interaction.

Many people only restart their phones when prompted by a security or system update, but the NSA’s guidance suggests this could be a significant oversight.

Regularly rebooting your device can also mitigate threats from spear-phishing and other types of malware, though it’s not a catch-all solution for all advanced threats.

In addition to rebooting weekly, the NSA advises mobile users to adopt several other security practices: disable Bluetooth when not in use, promptly install updates for the operating system and apps, and turn off location services when not needed. Strong lock-screen PINs and passwords are crucial, with a recommendation of at least a six-digit PIN and auto-lock features.

Cybersecurity experts also emphasize using unique, strong passwords for each account and being wary of email attachments and links, even from trusted sources. Recognizing phishing attempts and avoiding public Wi-Fi and charging stations are also key steps in maintaining mobile security.
