Experts are strongly advising all iPhone and Android users to turn off their devices at least once a week to safeguard against cyberattacks. This simple measure is recommended as a defense against "zero-click" hacking attempts, where hackers can infiltrate phones without any user interaction.
The National Security Agency (NSA) supports this tactic, suggesting that it helps clear data stored in background processes and web browsers. They also emphasize the importance of avoiding public WiFi networks and regularly updating phone and app software.
Risks of not restarting your device
Failing to switch off your device can leave it vulnerable to hackers, who may tamper with active web addresses and install harmful files. Restarting your phone not only helps remove these threats but also logs you out of banking and social media apps, potentially preventing unauthorized access to sensitive data.
Phishing and other threats
Regularly turning off your phone can also reduce the risk of phishing attacks, where attackers send malicious emails to steal login credentials or passwords. According to a 2015 Pew Research study, around 50% of mobile users rarely or never turn off their devices, and 82% said they seldom or never restart them.
The NSA advises users to update their software and apps regularly to close potential security loopholes. They also recommend disabling Bluetooth when not in use to prevent unauthorized access to your device.
Additional security measures
While these steps are not foolproof, they do offer some protection against malicious activities. The NSA cautions that mobile device threats are increasing in scope and complexity but notes that these steps provide some security without sacrificing convenience.
Deleting Wi-Fi networks that are no longer needed can prevent cybercriminals from targeting your phone. Be aware of SSID Confusion Attacks, where you might connect to a hacker's hotspot instead of a legitimate network with a similar name.
Email and messaging precautions
Be cautious with email attachments or links from unknown sources, as they can install harmful software without your knowledge. Oliver Page, CEO of cybersecurity firm Cybernut, told Forbes, "Falling for social engineering tactics, like responding to unsolicited emails requesting sensitive information, can result in account compromise and identity theft. These phishing attempts often mimic legitimate entities, deceiving individuals into divulging confidential details."
Page also warns about the dangers of trusting phone calls or messages without verification, as scammers can manipulate victims into disclosing sensitive information or taking compromising actions.
By following these recommendations, users can significantly reduce their risk of falling victim to cyberattacks and protect their personal information.
