IOS

IOS uses proprietary software. The attacks on these phones are limited since they are not open source systems.

Types of IOS Attacks:

Jailbreaking:

Jailbreaking may put the device at risk. It is done to gain administrative privileges and to download third-party application extensions, etc. Though, the device may lose its warranty, get infected with malware, drop in performance, etc. There are three ways jailbreaking can be done-

Tethered:

After a device is jailbroken, it will no longer have a patched kernel; it might go to a partially functioning state and requires re-jailbreaking using the same computer.

Semi-tethered:

When the device is turned off and on, it will no longer be jailbroken. The device can be used for normal functions.

Untethered:

The device once jailbroken remains jailbroken, and the kernel will be patched completely after reboot.

Countermeasures:

• Do not jailbreak the device.




• Apply strong encryption.




• Always connect to safe networks.




• Follow common security guidelines.




• Do not open links/attachments from unknown sources.
