Experts strongly recommend that both iPhone and Android users should power off their devices at least once a week to guard against cyberattacks. This straightforward measure serves as a defense against “zero-click” hacking attempts, where hackers can infiltrate phones without any user interaction.
Supporting this advice, the National Security Agency (NSA) suggests that regular restarts help clear data stored in background processes and web browsers. They stress the importance of avoiding public WiFi networks and keeping phone and app software updated.
The Risks of Skipping Device Restarts
Failure to restart devices can leave them vulnerable to hackers who might tamper with active web addresses or install harmful files. Restarting not only removes these threats but also logs users out of banking and social media apps, potentially preventing unauthorized access to sensitive data.
Guarding Against Phishing and Other Threats
Regular device restarts can also lower the risk of falling victim to phishing attacks, where attackers use malicious emails to steal login credentials or passwords. According to a 2015 Pew Research study, around half of mobile users rarely or never power off their devices, with 82% admitting to infrequent restarts.
The NSA recommends regular software and app updates to close potential security loopholes. They also advise disabling Bluetooth when not in use to prevent unauthorized device access.
Additional Security Measures
While these steps aren’t foolproof, they offer some protection against malicious activities. The NSA warns that mobile device threats are evolving, but stresses that these measures enhance security without sacrificing convenience.
Deleting unnecessary Wi-Fi networks can prevent cybercriminals from targeting phones. Users should also beware of SSID Confusion Attacks, where connecting to a fake hotspot can compromise security.
Email and Messaging Precautions
Exercise caution with email attachments or links from unknown sources, as they can install harmful software. Oliver Page, CEO of cybersecurity firm Cybernut, advises against falling for social engineering tactics, which can lead to account compromise and identity theft.
Page also cautions against trusting unverified phone calls or messages, as scammers can manipulate victims into revealing sensitive information.
By following these recommendations, users can significantly reduce their risk of cyberattacks and safeguard their personal information.
