![]() Learn how to manage the privacy settings of all the apps and services you use.Unfortunately, different apps (and different operating system options) implement their logout processes in different ways, so you may need to dig around to find out how to do this. Rebooting your device doesn’t “reboot” the logged-in status of the apps you use, so your phone starts back up with all your commonly used apps automatically reauthenticated to their respective online accounts, unless you previously logged out deliberately. But the best way to avoid exposing data by mistake is to authorise yourself, and therefore your device, to access it only when genuinely necessary. And logging in with passwords and 2FA codes via the fiddly keyboard of a mobile phone can be annoying. This is unpopular advice, because it means you can’t just open an app such as Zoom, Outlook or Strava and be back in the middle of a meeting, a discussion forum or a group ride at a moment’s notice. Explicitly log out from apps when you aren’t using them.Unfortunately, many mobile devices come with a raft of preinstalled software that can’t be uninstalled, known disparagingly in the jargon as bloatware, but some of these non-removable packages can be turned off to prevent them running automatically in the background. The best way to avoid having data snooped on by malware is not to have it stored where the malware can see it in the first place. ![]() If your needs change, you can always reinstall the app in the future. Uninstall unnecessary apps entirely, and delete all their associated data. Unfortunately, none of these are quite as easy and unintrusive as simply “turning it off and back on again”, but they’re all worth knowing about: With that in mind, here are some additional mobile cybersecurity tips to consider as well. If that’s how the attackers choose to do it, then religiously rebooting your phone every day will give you a false sense of security, because it will feel as though you’re doing something really important and useful, even though you aren’t. Then, the attackers can use the unauthorised code running inside your kernel to implant a persistent malware infection that will automatically start back up whenever your phone does. The attackers can use the non-persistent malware in your browser to compromise the kernel itself, getting control over your entire device. The malware might therefore be limited to the current browser session, so that rebooting your phone (which would bump the browser software and its injected malware code out of memory) would indeed magically disinfect the device.īut if the unauthorised code that the attackers run inside your browser via the zero-day WebKit bug follows up by triggering the other zero-day bug in the kernel, you are in a pickle. If attackers can only trigger the execution of unauthorised code inside your browser, then it’s likely that their malware won’t be able to escape from the browser process and therefore won’t be able to access or modify any other parts of the device. In that sense, regularly rebooting your phone won’t do any harm.Īpple patch fixes zero-day kernel hole reported by Kaspersky – update now! ![]() In malware terms, persistence generally refers to rogue software that outlives the app that launched it, that outlives your current logon session (if you’re on a laptop), or that survives even a full power-off and reboot.īut non-persistent threats are transient, and don’t survive from app launch to app launch, or from session to session, or from shutdown to reboot.Īnd shutting down generally closes all your apps, then closes down the entire operating system, thus stopping any malware or spyware that was active in the background, along with everything else. There’s some truth in this, given that malware infections can generally be divided into two separate categories, known in the jargon as persistent threats and the rest. Why at night? Why every day? Why for five minutes, and not, say, two minutes or 10 minutes?īut the Guardian suggests that the reason is that this will “stop any spyware that may be running in the background on your device.” ![]() Simple things, turn your phone off every night for five minutes.įor people watching this, do that every 24 hours, do it while you’re brushing your teeth or whatever you’re doing. UK newspaper The Guardian quotes the PM as saying: The Australian Prime Minister, Anthony Albanese, has apparently advised people Down Under to turn off their mobile phones once a day, for the surprisingly precise period of five minutes, as a cybersecurity measure. ![]()
