Computer experts are talking about a new Windows based trojan horse that sends spam messages to mobile phones through SMS. The Delf-HA Trojan downloads a spam campaign from the internet and then sends it to random mobile phones numbers in Russia. The attack utilizes the mail-to-SMS feature most cell phone carriers provide.
Although Delf-HA targets only Russian mobile networks, experts have warned that the same technique could be used to send spam to subscribers of networks in other countries.
