The first iPhone worm, iKee, appeared in early November 2009, created by a 21-year-old Australian student in the town of Wollongong. He told Australian media that he created the worm to raise awareness of security issues: jail-breaking allows users to install an SSH service, which those users can leave in the default un-secure state. In the same month, F-Secure reported on a new malicious worm compromising bank transactions from jail-broken phones in the Netherlands, similarly affecting devices where the owner had installed SSH (Secure shell tunneling) without changing the default password.
A Forbes staff analyzed UCSB study on 1407 free programs available from a third party source and Apple. Of the 1,407 free apps investigated in the cited study, 825 were downloaded from Apple’s App Store using the website App Tracker, and 526 from BigBoss (Cydia's default repository). 21% of official apps tested leaked device ID and 4% leaked location. Unofficial apps leaked 4% and 0.2% respectively. 0.2% of apps from Cydia leaked photos and browsing history, while the Apple store leaked none. He commented that unauthorized apps tend to respect privacy better than official ones. Also, there is a program called PrivaCy that allows user to control the upload of usage statistics to remote servers.
Installing software published outside the App Store has the potential to affect battery life and system stability if the software is poorly optimized or frequently uses resource-draining services (such as 3G or Wi-Fi).
