F-Secure Detects New Class-Zero-Message Tool

HushSMS lets you send a class zero message (aka Flash-SMS or stealthy PING message) to another mobile phone. The message is discarded on the owner¡¦s phone and no trace exists.

The sender will get back a message from the operator that their message has been delivered, thus knowing that the phone is switched on. The tool exploits a vulnerability in Windows Mobile 5 and 6 based PocketPCs.

HushSMS claims on their website zero class messaging is a freeware solution for professionals who need to check if someone¡¦s phone is switched on, to send ¡§information to that phone without it being stored¡¨.
