The National Security Agency has shared the following five steps iPhone users must follow in order to avoid hackers via the Daily Mail:
- Restart your phone once a week
- Disable Bluetooth when not in use
- Avoid using public USB ports
- Avoid using public Wi-Fi
- Cover your mic and camera
The NSA claims that restarting an iPhone one per week can combat zero-click hackers from infiltrating phone data, though it does not remove persistent malware. More serious issues will need a full factory reset, however, users are advised to turn off their phones completely and wait at least 10 seconds before turning it back on.
Bluetooth is a potential gateway for hackers, especially in public settings. Hackers use tools such as 'BlueSnarfing' to steal iPhone users' data and listen to person conversations.
Disabling Bluetooth when it's not being used can not only combat these issues but will also help save the phone's battery life. Additionally, iPhone users are advised to rename their device something specific, such as 'Device123,' as it makes it more difficult for hackers to identify the victim in public settings.
Public USB charing ports are believed to come with the risk of 'juice jacking,' which occurs when USC connections are used by hackers to install malware and steal the user's data. Regular power outlets, specifically charge-only cables, are believed to be better for use in public settings.
Public Wi-Fi also makes smartphone users susceptible to hacking as it's viewed as a playground for digital snopes. Smartphone users are advised to ask an employee at the location for the official Wi-Fi name in order to verify the network, rather than connect to malicious networks.
The NSA also advises users to cover the phone's microphone and camera when they are not in use. Hackers can activate information through 'hot-miking' attacks that tap into conversations without the user's knowledge.
