Update immediately iPhone your. Apple released iOS 14.4 update with fixes to three critical security gaps which are probably known.
Apple hasn't given too many details about the bugs, except of "they may have already been used".
A vulnerability even affects the kernel and an attacker could elevate their privilege level (such as Admin) να προκαλέσει σοβαρή ζημιά στη συσκευή σας ή να κλέψει τα δεδομένα σας.
Οι δύο άλλες ευπάθειες επηρεάζουν τη μηχανή απόδοσης WebKit της Apple που τροφοδοτεί το Safari. Επιτρέπουν στους εισβολείς να τρέξουν αυθαίρετο code that could be used to track you. We don't know if this can be done remotely or if the attacker needs physical 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, go to Settings – General – Software Update and do λήψη of the updated version.
