The package - more of a prank than a threat - poses as an "important
system" upgrade supposedly needed prior to upgrading to version 1.1.3 of
Apple's firmware. The "iPhone firmware 1.1.3 prep" seems to lack
malicious purpose. Problems kick in when users try to uninstall the
The bogus firmware reportedly affects components of other applications
during the install process including Erica's Utilities (a collection of
command-line utilities for the iPhone) and OpenSSH. If the user chooses
to uninstall the rogue package, these others applications will also be
removed leaving users of the much-hyped device with the chore of
reinstalling these applications.
"This is technically the first Trojan horse seen for the iPhone, however
it does appear to be more of a prank than an actual threat," Symantec
researcher Orla Cox. "The impact of uninstalling the 'Trojan' would
appear to be an unintended side effect".
Web sites hosting the malicious package were taken offline soon after
the discovery of the low-risk nuisance over the weekend. Although little
damage was done users ought to take the incident as a warning to be
careful about what packages they install on their phones.
