Jailbreaking an iPhone involves removing hardware restrictions imposed by iOS, allowing the user to gain root access to the operating system. This process can introduce significant security vulnerabilities, as it bypasses many of the built-in protections designed to keep the device secure. These vulnerabilities can lead to unexpected application behaviors, frequent crashes, and increased exposure to malicious software.

Application updates often include bug fixes for known issues. Updating the app is a non-destructive first step in troubleshooting application crashes.

Checking the data usage settings can help identify any unusual activity or data consumption by an app, which is a common symptom of a rogue or malicious application running in the background.

When a device is compromised by installing a malicious APK from an untrusted source, the most effective way to ensure all remnants of the malware are removed is to perform a factory reset. Before doing so, it’s crucial to back up important data that is not infected. This step restores the device to its original settings and removes potentially harmful software.

This is indicative of application spoofing, where an app pretends to perform a legitimate function but in reality, has ulterior motives, such as gathering sensitive personal data without the user’s relevant consent.

The first step should be to uninstall the recently installed app, especially since the issue started immediately after its installation, suggesting that the app may be causing network disruptions.
