Australia is considering the adopting of a code that would oblige ISPs to contact, and in extreme cases perhaps even disconnect, customers with malware-infested computers.
The voluntary eSecurity Code is designed to put a squeeze on the estimated 100,000 zombies in Australia, each of which might be capable of kicking out 10,000 junk emails a day.
Pilot data sharing schemes in Australia are praised for resulting in the reduction of malware-infected systems. Around 68 ISPs were involved in a 2007 Australian Internet Security Initiative (AISI) programme credited with reports of 10,000 compromises every day. The scheme cost a relatively modest A$4.7 million over four years.
