Unlocked iPhones at risk from trojan

Posted on 10 Jan 2008 at 09:58

Newly discovered malicious software is capable of deleting legitimate applications from unlocked iPhones, warns security firm F-Secure.

The trojan contains false installation information that causes other applications to be removed when the trojan is uninstalled, the firm says. The threat was first reported on ModMyiPhone.

F-Secure says this discovery should alert iPhone owners to the dangers of unlocking iPhones using a method that exploits a security flaw.

"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," says Jarno Niemela on the F-Secure website.

"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 a specific target," Niemela warns.

A popular iPhone hack relied on a vulnerability in the handling of TIFF images, which Apple soon fixed. However many users will not have applied Apple's patch, knowing that it is likely to relock their phone.
