YNet reports that the phone company is trying to find a way to block the messages:

Dozens of Israeli customers of the Orange cellular service provider received unexpected SMS messages on their phones Wednesday evening, with the English message:

“Now Now Now…Go out from your home Hizballah willing shelling of the area, Israel Government Cheating you And refuse recognition Defeat.â€?

[…]

Rani Rahav, a spokesperson for Orange, responded that the text messages were coming from a small service provider “somewhere out there in the Pacific Ocean. We are working right now to block the provider from transmitting further messages to Orange customers.�

Who pays for those SMS threats? We always hear about the Internet being a concern in modern information warfare, but cellular phones clearly play a more significant role since they are so mobile and resilient. Blocking an entire provider sounds like the system does not have granularity, which may turn into a sticky problem for Orange if the attackers can spread the origin of their messages. Denial of service also blocks helpful messages.
