Some of the great novels begin with the phrase “Whe I was a child”, which in its translation would be “When I was a child”. In this article you could not start otherwise, because when I was a child I loved to ‘tune’ my bike with those exhaust pipes that allowed you to pass the 50 km / h. Although all this at the cost of piercing the original exhaust and lose the warranty of my bike, but that was cool, made me feel bad …
Many of you will wonder what the motorcycle simile looks like in a technical article about the Jailbreak (JB). Well, I wanted to start with it because all of us who have ever seen the Jailbreak on our iPhone have felt the same as that 16 year old boy: free, challenging and… forgive me for throwing you a party, reckless .
Is the Jailbreak bad?
The Jailbreak itself is neither bad nor good, it’s simply a decision , you decide if you sleep with the window open on a lower floor because it’s hot even if you assume the risk of getting a poo in the room. In this case it’s the same thing.
Why did I say that doing JB is reckless? Because it’s become dangerous ground these days. Before, making JB to your device was more or less safe because those who promoted this research did it simply for the pleasure of knowledge, all this despite the fact that this functionality was limited to a circle of advanced users because of its complexity. Today there are slightly darker groups.
Performing the JB process requires making modifications at the CORE level of the phone and depending on the phone version is sometimes done at the hardware driver level. This means that sometimes you run the risk of touching up things on the phone that will give you a nice paperweight if something goes wrong.
Why do Jailbreak? (Or not)
There are several profiles of people who install JB today, and you’ll hear many of them self-deceive themselves when they say out loud that it’s simply to customize their devices outside of Apple’s yoke, when they’re simply looking to install pirated software. This is doubly counterproductive, as it takes away the small profit software companies can make, and what’s worse: we add software without any control to our device.
It is likely that the iPhone is one of the best encrypted devices within mobile telephony , but it is based solely on our unlock code. Yes, that same code that you are asked for when you install something. If you install a third party app without control, with obfuscated code that Apple has not verified and that does, among many other ‘cool’ things, sending your blocking code to a server located in some computer paradise , are we not sold?
From this moment on we will have a phone that is an open book for the owner of this server, which will be able to be from home eating pipes and seeing everything you have on your iPhone. Although perhaps this is the least of it, because this person or organization will be able to commit criminal actions in your name and all this with your mobile and your credit card . How does the body stay?
Why does the iPhone look like an open book with Jailbreak?
By performing the JB the user account acquires administrator permissions of the device, in addition to removing many of the limitations that Apple puts on our device to be very safe. In short, a privilege escalation is performed granting toral power to the user, including modifications in the operating system. From that moment, our iPhone will stop applying many security measures that the JB process deactivates . The clearest example is the typical illegal software that asks you to uninstall Antivirus in order to install it, which is a bit suspicious, isn’t it?
You may now wonder if all downloads outside the App Store are susceptible to mistrust. My personal advice is not to install anything that is not outside the App Store or that is not from a company with an impeccable reputation. If you keep pulling the strings, you’ll also find that installing untested developer certificates and betas from dodgy sites is just as unwise.
Some people claim that paying money to upload applications to the App Store and to have a developer’s profile is foolish, which is as stupid as saying that an iPhone is only worth the 200 euros it costs to build it. This only shows a total ignorance of the subject.
In short, you could summarize this article in that the Jailbreak is not in itself a bad thing. What really makes the idea of this bad is to install tweaks from pirate repositories that install malware . As some people say, with great power comes great responsibility, and if you are into security it is sometimes exciting to see how they have managed to install Cydia on an iPhone through an exploit. But if you’re a normal user who just wants to avoid paying the £3 that an app can be worth, the JB can be your worst ally .
