Software updates for your devices should generally be installed as soon as possible. But iOS and macOS users have a particularly valid reason for this: Apple warns of dangerous vulnerabilities in its operating systems.
In its American support area, the manufacturer points to several vulnerabilities, which closes the update to iOS 12.2 . A corresponding overview is also available for macOS Mojave 10.14.4. Updates for both operating systems are available for free download since March 25, 2019. Apple released it shortly after the launch of its video streaming service .
US agency recommends quick update
Not only Apple urges to install the updates, also the US Department of Homeland Security subordinated Cybersecurity and Infrastructure Security Agency (CISA) considers this, according to Heise for absolutely necessary. According to the agency, attackers could otherwise take your device remotely. If you use an older version than iOS 12.2, you run the risk that hackers activate the microphone of your iPhone or iPad without your knowledge. Even manipulated websites should be able to do so.
Apple’s GeoServices are also affected: If you click without iOS update to a malicious SMS link, this could trigger the execution of malicious code. According to Heise, “government agencies” use such vulnerabilities to take over iPhones from target individuals. The same vulnerability apparently affects Apple TV 4K and HD , so you should also update tvOS to version 12.2.
iOS: Also affected by Safari and Siri
On iPhones and iPads, Safari is not safe without the iOS update: According to Apple, websites could access sensitive information without your consent. The reason for this is supposed to be an “authorization problem”, which comes into play when reading the light and motion sensors of iOS devices. The dictation feature of Siri turn should be activated by malicious software without your consent. This could probably accommodate third parties your conversations.
Overall, iOS 12.2 should address over 50 vulnerabilities. The update is just over 800 MB in size, which is why the download via a WLAN is recommended. If your iPhone or iPad does not offer you the update automatically, you will install it as follows: Under “Settings | General”, tap on “Software update” and then on “Load and install”.
MacOS update strongly recommended
Even Mac users should not spend too much time updating their operating system. The update to macOS 10.14 Mojave closes 38 vulnerabilities. In older versions, apps should be able to read sensitive data from the Mac keychain. In addition, it is possible malicious software to obtain root privileges. A security expert said this vulnerability in macOS should be very easy to exploit.
Who still uses macOS (high) Sierra does not necessarily have to switch to macOS Mojave. Apple has also released security updates for macOS 10.13 High Sierra and macOS 10.12 Sierra. However, it is important: Whichever version you use, install the appropriate security update as soon as possible.
Mac OS (High) Sierra users may need to update Safari separately. Apple recently released version 12.1. In macOS 10.14 Mojave this is already included. As mentioned earlier, there is also a security update for Apple TV 4K and HD. This is included in tvOS 12.2. A timely installation is also recommended here.
