An Israeli security firm has published a proof-of-concept pointing a weak link in Apple's otherwise very tight security for its mobile platform iOS -- mobileconfig files. The profiles, which are often installed by carriers or enterprise device management solutions, can be downloaded from unencrypted websites, reports Skycure Security. If users were tricked (through social engineering or redirected websites) into installing a malicious profile, it would configure system-level settings to allow attackers access to several key iOS services.
