Hits Curse of Silence Nokia S60 Phones


A new vulnerability is hitting certain Nokia phones: the “Curse of Silence” affects Nokia S60 devices running 2.6, 2.8, 3.0, or 3.1, and blocks your phone from receiving SMS and MMS messages. Unfortunately, you can’t solve the problem with a simple power cycle - according to the advisory, you need to perform a factory reset to fix it. The good news is that it’s more annoying than dangerous, since the attack requires the phone number of the recipient/victim.

The attack requires a (email) message sent that contains an email address with a length greater than 32 characters, followed by a space. Depending on the target’s S60 version, one of two things will happen:

1) S60 2.6 and 3.0 (mostly oldschool Nseries phones, N80, N91, N92, N93/N93i, E65, E70, etc) will not be able to receive SMS or MMS messages until a factory reset.

2) S60 2.8 and 3.1 (N95, N95 8GB, E66, E71, 5700 XpressMusic, N81, etc) require 11 emails to be sent in this fashion. Then the target will still receive parts of SMS messages, but only if it’s one long message broken up into small pieces. Power cycling will barely help in this case - it’ll allow one more part to be received before the phone goes nuts. A factory reset will solve the problem.

Right now, there’s no user fix for the vulnerability. Network operators can defeat the attack by just ignoring messages with email addresses > 32 characters, but that doesn’t seem very likely.

The discovery of the attack was made by Tobias Engel, and he’s provided a nice list of phones affected. It’s quite large:
