手機長時間開機風險高？如何有效防範黑客攻擊

Is keeping your phone on for extended periods risky? How to effectively prevent hacker attacks

In an era where smartphones are highly prevalent, whether for daily communication, online payments, or using travel SIM cards or eSIM services, most users are accustomed to keeping their phones powered on for extended periods. However, this also increases cybersecurity risks. According to public recommendations from the U.S. National Security Agency (NSA) and various cybersecurity organizations, keeping a phone on for too long can increase the likelihood of it being hacked. Regularly restarting your phone is considered one of the simple yet effective mobile security measures, helping to reduce the risk of system vulnerabilities being exploited.

This article will delve into how to prevent mobile attacks and comprehensively enhance personal data protection.

The Importance of Weekly Phone Restarts: Reducing Zero-Click Attack Risks

Zero-click attacks are advanced cyberattack methods where hackers can infiltrate a phone's system through vulnerabilities in messaging applications or communication protocols without requiring any user action, such as clicking a link or downloading a file, to monitor or steal sensitive data.

The U.S. NSA recommends users restart their phones once a week because rebooting the device can interrupt the continuous operation of some malicious programs, reducing the success rate of long-term dormant attacks. While this method cannot completely block hacker intrusions, it is practical for enhancing overall cybersecurity protection.

Recommended Phone Security Settings: Effectively Protecting Personal Data

In addition to regularly restarting your phone, establishing good phone usage habits is also crucial. Here are some practical tips to protect your phone from hackers:

  • Disable unnecessary Bluetooth and GPS services to reduce tracking or intrusion risks.
  • Regularly update iOS or Android operating systems and applications to patch security vulnerabilities.
  • Avoid using public Wi-Fi or unencrypted networks to reduce the chance of data interception.
  • Beware of spear phishing; never click suspicious links or attachments.

These basic settings and operations can significantly enhance phone security and personal data protection.

Overseas Travel Internet Security: Key to Choosing eSIMs and SIM Cards

For users who frequently travel abroad or use international SIM cards and eSIMs, network security is even more important. Using free Wi-Fi at airports, hotels, or coffee shops carries certain risks, as hackers might intercept data through unsecured networks.

Therefore, it is recommended to choose a secure and reliable travel SIM card or eSIM solution to ensure stable network connectivity with encrypted transmission. This not only enhances the internet experience but also effectively safeguards personal data.
