Anything that is not "air-gapped" meaning it is connected to a network directly like your iPhone can be hacked. Though, The iPhone is undoubtedly more resistant than the competition when it comes to hacking.
Apple keeps tight control over both software and hardware, resulting in a secure device. However, certain things can pierce your iPhone’s security.
I will explain for you to gain a better understanding of what can affect your iPhone’s security (and user experience):
Jailbreaking
If you jailbreak your device or run an enterprise developer account, you have the option to install apps outside of the App Store. This may (unknowingly) result in malicious apps taking place on your iPhone. In short, never jailbreak!
Accessing unknown links
Your iPhone can be compromised if you open harmful phishing links you receive on iMessage or email from anonymous people. If you are unsure of a link to not click it. Believe nothing is that important and you did not win a gift card!
Downloading apps from unknown sources
Apple is strict about the App Store rules and does not allow any malicious apps or existing app updates that may compromise your device’s security. Additionally, you cannot download apps from anywhere else except the official App Store.
These two factors bring down the risk of being troubled by a third-party app to a minimal level. But still, in rare cases, an app may get through approval with malicious code.
Additionally, installing random third-party keyboards and giving them full access can also affect your iPhone’s security.
EASIEST WAY FOR ME TO PENETRATE AN IPHONE IS Public charging stations/Wi-Fi
Using untrusted public charging stations might be the culprit (especially if your iPhone is unlocked). Be tech-savvy and add passcodes and keep your phone locked tight. Also, using free public Wi-Fi for bank transactions (and similar data-sensitive procedures) on your iPhone can prove disastrous.
Has your iPhone been hacked? Here’s how to check
- You may see new apps on the Home Screen that you don’t recognize.
- There may be a severe battery drain.
- The iPhone may run hot and open apps randomly.
- Your iPhone is exchanging an abnormal amount of data.
- The keyboard may misbehave and type random words.
- Call, message, and email history may have unknown entries that you didn’t make.
- You may see random popups on your iPhone.
If you notice one or more of these points, there’s a good chance some malicious code landed itself on your iPhone. (Your phone may run hot when under stress, this is normal. If your iPhone is hot when you don’t have CPU-intensive apps open, its cause for concern.)

- From the next screen, turn it off.
