The developers behind the App, SektionEins GmbH wrote on a blogpost : “[We] wanted to provide the public with a low cost solution that allows to find out if someone used one of the public jailbreak or a customized version to hack and backdoor your device,” the developers wrote in a blog post. The app is developed by a team led by Stefan Esser who is a well-known iPhone security researcher. The app not only detects a jailbreak, but also analyzes the processes running at the moment, as well as any anomalies that could be the sign of some privacy or security breach.
