Further to my earlier posting about the dangers of folk hijacking your PC to send spam, here’s something from Reuters, appearing on Wired News that confirms the worst: Nearly 2,000 PCs with high-speed Internet connections have been hijacked by a stealth program and are being used to send ads for pornography. The stealth program is a Trojan called “Migmaf” for “migrant Mafia”, and Reuters quotes Richard M. Smith, a privacy and security consultant in Boston, as saying most of the PC owners likely have no idea what is happening. Smith said he suspects whoever is responsible for the Migmaf scam may be in Russia, because some e-mail addresses involved in the scheme go back to Russian servers and there are other Russian language references in some related domain names.How to avoid become an unwitting pornographer? Use a firewall like Zone Alarm (there’s a free version, which should be enough for your needs) and keep your virus checker running and up to date.
