ACMA: 30.000 pc’s infected in Australia per day

Anti-spam and malware enforcement agency ACMA reports on this (shocking high?) figure. Keep this up and ca. 50% of the Australian population is infected within a year.

I remember a presentation from Sweden only a few years ago, that there were only a little over a thousand infected pc’s in Sweden. (Reactions were: that can’t be correct. Too low)

Do you know what the numbers are for your country and maybe more importantly what your government and/or Industry is/are doing about it? E.g., is there something like a botnet task force? See:

This German example may give you an idea how government and Industry can work together in combatting the consequences of infections. ISPs in the Netherlands are also working together.

Of course this is all after the fact, but the bots are reported to become possible dangerous offences weapons, so bringing numbers down is one of the weapons of choice for a government.

  1. The reason why I hardly detect any bots in Australia is probably because my detection mechanism is only good at finding bots abusing open relays. Perhaps bots in Australia are seldom used in this way? Or Australia ISP’s have been filtering over their submarine cables to block suspicious outbound connections?
    My website is Daily Botnet Statistics, at I believe detecting botnets and notifying the victims are the only way to win the war against botnets. I often detected more than 3,000 bots every day when I started a year ago, and now I detect less than 2,000, sometimes no more than 1,000, bots daily. It might indicate that my detection is no longer effective now. But another interpretation is that spammers have been forced to change how they send spam, right?

  2. Dear Chih-Cherng Chin,

    Thank you for your response. In the ITnews article it is also mentioned that the estimation for infected pc’s in Australia is 3 to 4 million total. But you are right that the sentence on the infections per day is ambiguous. Still they are high numbers. Do you have an explanation why Australia does not turn up in your stats? if you want to join the link to your site with my blog readers, please do so.


  3. I have been doing my own botnet detection for over a year. Every day I publish on my website the top 10 networks and countries with the most bots for the previous day. Perhaps caused by the way I detect botnets, I rarely detect any bots from Australia.
    My interpretation of ACMA’s statement is that 30,000 malware-infected pc’s are detected per day. There will be many infected pc’s being detected repeatedly for several days. I really don’t think that they implied there are 30,000 newly infected pc’s in Australia every day.
