iPhone and Android users issued urgent warning to switch off their phones

A significant cyber threat has prompted an urgent warning to all iPhone and Android users. Users are being advised to power down their devices weekly in order to thwart cyber criminals. This strategy aims to combat so-called "zero-click" hacks which install spyware onto smartphones without any action from the device owner.

This measure is championed by the National Security Agency (NSA), as it temporarily clears data stores that operate in the background or via internet browsers. Alerts have also been issued regarding the use of public WiFi networks, alongside reminders to update phone software and apps on a regular basis.

Should mobile phones not be routinely powered off and on, hackers have the opportunity to affect open web addresses, deploying malicious files onto the user's device in the process. The straightforward act of switching off and then back on effectively logs out of banking and social media platforms, subsequently shielding sensitive data from online infiltrators.

The same can be said for phishing attacks, where wrongdoers send deceitful emails with the aim of obtaining confidential information such as login details or passwords. Astonishingly, according to a study by Pew Research in 2015, nearly 50% of mobile phone owners seldom or never switch off their devices, while a staggering 82% confessed to rarely or never rebooting their phones, reports the Mirror.

The NSA has advised users to regularly update their software and apps to ensure their devices are secure. By updating old software, potential loopholes where data can be accessed are removed.

It also recommends disabling Bluetooth when not in use to prevent unauthorised access.

However, these measures are not 100 per cent effective but should provide some protection from malicious activity. The NSA warned: "Threats to mobile devices are more prevalent and increasing in scope and complexity, but added the steps " but added that the steps "provide convenience and capability but sacrifice security."

WiFi networks should also be deleted to prevent cybercriminals from targeting people's phones. Users should also be aware of SSID Confusion Attacks, where they may connect to a cyber attacker's hotspot instead of an official WiFi with a similar network name.

People have also been warned about opening email attachments or links from unknown sources, which could result in the installation of malicious software without their knowledge.

Oliver Page, the CEO of cybersecurity company 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."

"Trusting phone calls or messages without verification can lead to serious consequences, as scammers manipulate victims into disclosing sensitive information or taking actions that compromise their security."
