Update your iPhone immediately. Apple has released the iOS 14.4 update with fixes to three critical security gaps which are probably known.
Apple did not provide too many details about the bugs, except that "they may have already been used."
A vulnerability even affects the kernel and an attacker could elevate their privilege level (such as Admin) can seriously damage your device or steal your data.
The two other vulnerabilities affect the machine απόδοσης WebKit της Apple που τροφοδοτεί το Safari. Επιτρέπουν στους εισβολείς να τρέξουν αυθαίρετο κώδικα που θα μπορούσε να χρησιμοποιηθεί για να σας παρακολουθεί. Δεν γνωρίζουμε εάν αυτό μπορεί να γίνει από απόσταση ή εάν ο εισβολέας χρειάζεται φυσική access to the device.
Over time, we may learn more about these security holes, but for now it's important to update your iPhone to iOS 14.4 right away.
To do this, follow the path Settings - General - Software Update and download the update.
