An analysis of SMS traffic conducted from March through December 2010 reveals that according to the reports of misuse submitted by AT&T, Bell Mobility, KT, Korean Internet & Security Agency, SFR, Sprint, and Vodafone consumers, spam is found across all networks, and at levels higher than originally anticipated.
The reports were collected by the pilot of the GSMA Spam Reporting Service (SRS), which identified and aggregated reports submitted by users via a short code. It also showed that addressing this would help improve the security and stability of networks and help lessen unwanted traffic on networks which currently clogs and wastes valuable bandwidth.
Attackers are using sophisticated message modification techniques and transmitting low volumes of messages from each sending number to avoid detection over a long period of time. Their methods vary across different regions, making global collaboration even more critical to combating this issue.
Further findings show that most spam originates on-network, followed by peer networks and then through internet services, but each mobile network operator in the pilot was able to identify the source of the spam and take immediate action.
