Mobile operators are being warned to brace themselves for a global upsurge in mobile messaging abuse.
The growth of mobile messaging, reductions in message delivery costs, inherent network vulnerabilities, and new mobile marketing initiatives are converging to create a perfect storm for abuse, according to mobile security firm Cloudmark. It reports mobile spam is becoming a growing problem.
China and Southeast Asia are at the leading edge of the problem, partly due to low costs in sending and receiving text messages. In China, the average subscriber receives between six and 10 mobile spam messages per day.
Meanwhile, in India some operators face spam levels of about 30 per cent, even after protocol-level filtering. Levels of spam in Japan are likely to increase as operators open their networks to email-to-SMS and MMS services, Cloudmark warns.
Attackers are applying techniques familiar to those at the receiving end of conventional email spam to the medium. For example, spammers are impersonating other mobile phone numbers and networks to send out spam using SMS spoofing techniques. Unregistered pre-paid SIM cards are also being used to distribute mobile junk messages.

The only time at which they claim responsibility is when you complain in a way at which they cant deny.
I once sent a couple of sms to Newzeland. United States and some to Nigeria e.t.c. All were not delivered and guess what they said?
They said our codes are not listed in theirs hence they can send to us.

Tell me about it. Every time I go to net with the phone, even for a moment, I get few of them. There's no end to it, and it is so annoying. Mostly about porn sites.

In this case these are sent as sms or mms. Very often you get a missed call, ringing not enough time even to answer it. Usually I do not call back if I hear it ringing for that split second, but if I see it after, sometimes I call back, to find some machine talking to me and playing some melody. So effective, cause it is sure thing that from ten times it gives you a call, one time you will call back.
