How to Block Cydia, protect iOS Apps from Jailbreak Tools
Learn 3 easy steps to Block the Cydia alternative app store to protect iOS apps against Jailbreaking and Jailbreak bypass/hiding tools. No code. No SDK.
What is Cydia?
Cydia is an alternative app store (repository) that allows users to find and install software not authorized by Apple on jailbroken iPhones, iPads and iPod touch devices. It also refers to the digital distribution platform for software on iOS accessed through Cydia software. Look no further than YouTube or just do a quick Google search and you’ll find hundreds of tools, apps, mods that are freely available on Cydia and specifically designed for hacking iOS apps.
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.
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.

Why Should Developers Protect iOS Apps From Cydia?
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. If you don’t know exactly what you’re doing or if you’re not careful there are a lot of things that can go wrong. For instance, the device may become prone to unexpected behavior, for example, due to bad or malicious tweaks or malware, which often masquerades on alternative app stores like Cydia. Also, the increased file system access opens up a much broader attack surface and can serve as an easy entry point for malware to enter or be delivered. Many malicious apps/tweaks are specifically designed to inject malware, spyware or adware, and these malicious programs are often hidden inside non-malicious software or apps.
Appdome Jailbreak Prevention enables an iOS app to protect itself against Jailbreaking and Jailbreaking tools found on Cydia. 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.
3 Easy Steps to Protect iOS apps against Jailbreak tools found on Cydia
Please follow these 3 easy steps to add Jailbreak Prevention to any iOS app and prevent hackers from using Jailbreak and Jailbreak bypass tools downloaded from Cydia.
- Upload an iOS App to Appdome’s no code security platform (.ipa)
- In the Build Tab, under Security, Select Jailbreak Prevention (shown below)
- Click Build My App
Congratulations! The app can now defend itself against Jailbreak tools found on Cydia.
Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps with RASP (Runtime Application Self-Protection), such as Jailbreak Prevention. When an Appdome user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.
Here’s what you need to build secured apps with Jailbreak Prevention to protect against Jailbreak bypass tools found on Cydia.
- Appdome account (If you don’t have an Appdome account, create a free Appdome account here)
- Mobile App (.ipa for iOS)
- Signing Credentials (e.g., signing certificates and provisioning profile)
