An SMS exploit in Nokia's S60 user interface was uncovered earlier this week. It allows an attacker to disable the phone's ability to receive messages. The exploit is found in Nokia's S60 3rd Edition platform, though phones with Feature Pack 2, such as the new Nokia N96 or Nokia N85, are immune to the attack.
The so-called Curse of Silence exploit requires the attacker to send a specially formatted message repeatedly to the victim's phone. The message quietly disables the recipient's ability to receive messages, though the other features of the phone continue to function normally.
Affected cell phones, though, can easily be fixed by simply performing a hard reset, which erases the phone's memory and restores it to its factory state. Due to the measures required to perform the attack, the vast majority of users are highly unlikely to experience a Curse of Silence attack.
