Securing every machine on the internet would be a good start. 95% of all spam messages I have seen lately gets send from DSL or Cable IP addresses. These are machine which run spamware without the user knowing (s)he is sending out spam by the buckets untill their ISP shuts them down.
Really? 95%? Does anyone have sound statistics on how much spam comes from DSL/Cable IP-space? And further, does anyone have any idea how to pick apart how much of that is simply relaying type activity vs.dedicated spam-bot activity? On the first question, I've seen many estimates over the last year or so suggesting everything from 25% (admittedly that was one of the earliest such estimates) to 40% and 60%, and recently a few claims of the "as much as..." variety pegging it at 75% and 80% (don't ask for references -- this is all from memory...). So, has any really good, large-scale sampling of these issues been done, perhaps by the large Email/anti-spam managed services folks?? -- Nick FitzGerald Computer Virus Consulting Ltd.
