How to Block the Chimera iOS Jailbreaking Tool

Learn 3 easy steps to Block Chimera Jailbreak iOS Tool and prevent Jailbreaking iOS.

What is Chimera Jailbreak?

Chimera is a Jailbreak tool for iOS 12 that claims to not tamper with user files. The makers of Chimera attempt to differentiate it as ‘safer’ than other Jailbreak tools.

Chimera jailbreak comes with a package manager called Sileo (which is an alternative to Cydia). Sileo features a UI that enables administrative access to the iOS file system and the ability to modify iOS system files with a high degree of administrator privilege.

What is iOS Jailbreaking?

Jailbreaking is the process of unlocking the iOS operating system on an Apple mobile device. Jailbreaking is a form of administrative privilege escalation, which bypasses Apple’s restrictions, resulting in full administrative control over the OS (the highest level of administrative privilege possible).  Jailbreaking is often accomplished by exploiting bugs in Apple’s software/firmware or modifying system kernels to allow read and write access to the file system. Jailbreaking is one of the primary methods/tools for every hacker – both black hat hackers and white hat hackers (eg: penetration testers or security researchers). They all use Jailbreaking in similar ways (to compromise the security model of mobile devices, the operating system, and any app running on the device). The main difference is that black hat hackers have malicious intent, while white-hat hackers generally have non-malicious intent.

Here are the Top 5 reasons people Jailbreak iOS/ iPhones

  1. To bypass Apple’s restrictions and install software Apple doesn’t support or sanction.
  2. To change the behavior of the OS in ways that Apple does not support
  3. Developers Jailbreak iOS to access and or modify the file system, test new app builds, install a wider variety of software programs to test their app to validate the security model of their app, etc
  4. Gamers or hackers Jailbreak iOS to access alternative app stores like Cydia or Sileo. These repositories allow for the installation of game mods, tweaks, cheat tools, and more advanced hacking tools.
  5. Pen testers and Hackers Jailbreak iOS to gain an advantage in compromising the security model, to expose weaknesses in mobile app protections, to disable anti-tampering or other security protections, to turn off security SDKs that have been hard-coded to the app.

Whatever the intent, Jailbreaking makes every hacker’s job much easier by providing a significant advantage to compromise the security model, due to the elevated level of privilege and full administrative control that Jailbreaking enables. Jailbreaking provides unfettered access to alternative repositories like Sileo and Cydia, where one can obtain any number of tweaks, mods, fake apps, clones and. more. Jailbreaking makes it easier to disable anti-tampering protections, turn off digital rights management checks. Bottom line: Jailbreaking compromises the mobile security model. It enables hackers to send fake signals, to modify code, to modify the file system, to disable security protections. Any iOS app that runs on a Jailbroken device is in a vulnerable state, where hackers can amplify and increase the magnitude of their attacks – all with less effort. And there are many easy to use tools hackers can

How to Block Chimera from Jailbreaking iOS apps

Appdome Jailbreak Prevention enables an iOS app to protect itself against Jailbreaking and Jailbreaking tools like Chimera. You can use Appdome to build Jailbreak Prevention into any iOS app – without coding. When the Appdome-secured app detects that it’s running on a Jailbroken device the app will shut itself down (default behavior) after displaying a message to the mobile user. This protects that app, user, and mobile data from being compromised or attacked by a malicious actor using Jailbreaking.
