OIX (aka Phorm) wouldn't be one of them?
Almost half the websites pushing malware are hosted by just 10 networks, according to a new report that adds new support to the growing argument that a relatively few number of actors are responsible for most of the net-based threats. The report (PDF) from StopBadware.org also showed a dramatic rise in China's role in the …
I looked at my firewall log and the number of packets blocked from the 188.8.131.52 netblock exceeds the number of blocked packets from all other IP addresses. So on a sample of 1, 50% of blocked packets are attempts at messenger spam (ports 1026,1027,1028) from that netblock. Perhaps Shaw Cable could address this issue. Certain other specific blocks also feature frequently, so they're not the only ones.
In my experience most SPAM comes from the US, Turkey or sometimes Russia. It looks to me like some US people are compromising Chinese sites to spread malware if you follow the chain back.
Of course it's popular in the US to blame the Chinese. Of course your network admin could always block all Chinese sites........
... spam-filters, whitelists, blacklists, the lot - it's all a complete waste of time. It's time to take this fight offline and into the IRL world.
There are only a small number of people engaged in serious spamming and virus attacks, and they all have names and addresses in the real world. The rest of us outnumber them a million to one. We should just kill them all. One quick night of the long knives, and the whole problem is solved for at least a generation.
Not surprising China gets a mention. After analysing the IP addresses of people trying to relay off my mail server I found that I could kill 95% of the problem by blocking addresses from this country. Subsequent checking of the logs shows all manner of IP detritus seeking to find "exploit nirvana" on my humble fixed IP.
Perhaps I have it all wrong and the friendly folk of that nation are just trying to reach out and touch the western community in anticipation of forthcoming olympic games!
