# Are Certain Banking Apps Using a 0-Day Sandbox Escape to Detect TrollStore?

Apple's security technique of sandboxing has long been hailed as a safeguard against malicious apps from accessing sensitive information on devices. By isolating app processes into their own protected environments, Apple aims to prevent unauthorized access to file systems and other critical areas. However, in a surprising twist, it appears that certain banking apps hosted in the App Store have begun shipping with a sandbox escape – a feature that allows them to detect the presence of TrollStore, an unsigned app installation tool.

## The Sandbox Escape: A Tool for Detection

TrollStore is not a jailbreak, but rather an exploit that enables the installation of unsigned apps on devices permanently. Unlike traditional jailbreaking methods, TrollStore uses a CoreTrust vulnerability to bypass Apple's security measures. This means that users who install TrollStore can access and run apps without needing an Apple Developer account.

## The Concerns

The introduction of sandbox escapes in banking apps raises several concerns. Firstly, it suggests that Apple may not be as vigilant as expected in vetting its app offerings before they reach the App Store. By allowing certain apps to bypass the sandbox, these developers are effectively circumventing a crucial security mechanism designed to protect users' sensitive information.

## The 0-Day Sandbox Escape: A Powerful Tool for Detection

The sandbox escape at the heart of this controversy is particularly concerning because it is a 0-day vulnerability – an exploit that has not been reported or patched by Apple. This means that even the latest firmware versions may still be vulnerable to attack, potentially allowing these apps to access sensitive data on users' devices.

## The Banking App Connection

While the exact banking apps affected by this issue have not been publicly identified, it's clear that they are taking proactive steps to protect their users from potential threats. By detecting TrollStore's presence and preventing its installation, these apps aim to safeguard against unauthorized app installations that could compromise user data during banking activities.

## Apple's Response: A Call for Action

As this news raises questions about the efficacy of Apple's security measures and the actions taken by its developers, it's essential that the company takes a proactive stance. By allowing certain apps to bypass the sandbox, Apple may inadvertently create an environment where developers can exploit vulnerabilities in pursuit of security enhancements.

## Conclusion

The use of 0-day sandbox escapes by banking apps to detect TrollStore is a concerning development that highlights the ongoing cat-and-mouse game between app developers and security experts. As we navigate this complex landscape, it's crucial for users to be aware of these risks and advocate for more robust security measures from Apple and its partners.
