Trojan created for jailbroken iPhones

F-Secure reports a trojan has been created for jailbroken (unlocked) iPhones. A trojan is simply an application that tricks users into installing it by promising something other than what it actually does when executed.

“The trojan installation package contains false application installation information that causes legitimate third party applications to be removed if the trojan is uninstalled from the iPhone,” F-Secure reports. “Web sites hosting the malicious package were taken offline soon after the discovery of the low-risk threat.”

F-Secure opines, “Hopefully this serves as a warning for those who have opened their iPhones using a security hole in the system and then installing unverified software without a second thought to what they are doing.”

F-Secure warns, “This time it was an 11-year-old kid playing with XML files who created the trojan. Next time it might be someone else with more skills and with specific target.”

MacDailyNews Take: This does not affect locked iPhones running Web apps as intended by Apple. As we always advise Mac users: Do not install anything from an unknown and/or untrusted source. iPhone is not currently set-up by Apple to have unauthorized applications installed and run, so be extra careful if you have jailbroken your iPhone or wait for Apple’s official SDK (February) and the attendant iPhone firmware update before installing third-party iPhone applications.

  1. A [one][1] trojan. Well that seals it then, we should stop using all Apple products today and go back to uh… um… ummmm… What was it again that we were using before, that was more secure than OS X – uh – Oh wait, I remember – NOTHING!

  2. A Trojan should be no big surprise. They exist for every system that allows users to install their own applications. Of course the Jailbroken iPhone is the only iPhone that allows the user to install their own apps.

    No news here – move along …..

  3. Of course, because there’s malware for jailbroken iPhones but none for legit iPhones, must mean that the vast majority of iPhones are jailbroken. The legit ones are only secure because there are so few of them…
