Australian ISPs To Disconnect Botnet "Zombies"

jibjibjib writes "Some of Australia's largest ISPs are preparing an industry code of conduct to identify and respond to users with botnet-infected computers. The Internet Industry Association, made up of over 200 ISPs and technology companies, is preparing the code in response to an ultimatum from the federal government. ISPs will try to contact the user, slow down their connection, and ultimately terminate the connection if the user refuses to fix the problem. It is hoped that this will reduce the growth of botnets in Australia, which had the world's third-highest rate of new 'zombies' (behind the US and China)."

      They usually watch for excessive traffic on specific ports. Since the most immediately profitable use of a botnetted machine is spam, the majority of botnetted PCs are either running open mail relays or are themselves functioning as outgoing mailservers. Many ISPs (including two in my area) watch for excessive traffic going OUT on TCP port 25. Unless you are running a mailserver, your computer has no legitimate reason to send out over that port in volume. Most ISP mailservers are SSL nowadays anyway and are off port 25 so you don't even need to use that if you are connecting to your ISP's mailserver from off-network. (and many ISPs outright block port 25 outgoing from anything in their network besides their mailserver) Many ISPs react the same if your computer is listening on port 25 (acting as an open relay)

      So if you are pushing megs (or gigs) a day every day on port 25, there's better than 99% chance your machine is botnetted. It doesn't take speculation to figure that out, and the odds of false-positives are very close to zero.

      That said, I have no sympathy for someone that knows their computer has a problem that's causing other people grief. That's the most basic understanding of the problem that is given when your ISP gives you a phonecall or email saying you have a problem and need to fix it or we will cut you off. If you're too stupid to acknowledge this and take responsibility for fixing it, or just plain don't care, I'd much rather see you off the internet and out of my Inbox. If you don't care that someone else has violated you by hijacking your computer that's fine with me, until they start using it to violate me, and that's when I start having a say in the matter.

      If you want a fun example to separate the computer from the problem, here's something easier to understand: ABC Construction company does building demolitions. They leave their explosives on site and not locked up. They keep getting their explosives stolen. OK I don't care about that, it's their loss. But then stuff around town start getting blown up and the explosives are easily traced back to you. That's when it's time for the police to come have a talk with you about securing your explosives. You do not have the right to continue leaving dangerous things so easily accessible that the public is constantly being hurt by them. Even if you want to ignore your moral responsibility for it, the public won't stand for it and you lose your say in the matter. You WILL secure your things or you WILL go away.

      Another excellent example is how several states legally require you to have a lock on your anhydrous ammonia tanks to prevent theft and use in drug manufacture. Also, most universities now are requiring students to install AV software on their computers before they're allowed to use the campus net. Your precedents have already been set.

      I've made some similar experience on my own some years ago while living on campus connected to a network of about 1,000 machines. The admins enforced a "three strikes" directive: if someone's machine was spreading viruses via internet access or via FTP/SMB shares or misbehaved in other ways (disturbing the DHCP and break-in attempts on internal servers, mainly), (s)he got a notice in her/his (real life!) post box to stop misbehaving/to fix the computer. As I recall, the note contained a paragraph offering help in case people weren't able to cope with the problem themselves. They only had to block less that 10 Machines during the time I lived there (4 years, approx.), as people really reacted quickly and we could even observe a (small) learning curve because new inhabitants mostly were briefed by their neighbours shortly after they had moved in.

    They don't need to disconnect bad users. They should just give a discount to users who are running secure operating systems that are more resilient to malware infections than Windows is.

    For example, give OpenBSD users a 50% discount, since it's quite unlikely that their system will ever get infected or compromised. The same can probably be done for users using Solaris, NetBSD, FreeBSD and commercial UNIXes.

    Linux and Mac OS X are more widely used than the aforementioned systems, so the chance of them getting compromised is greater, although still virtually non-existent. Give such users a 25% discount.

    Assume that the latest version of Windows is somewhat immune. Give Windows 7 and Windows Server 2008 users no discount. That is, they pay the base rate.

    Assume that older versions of Windows have been compromised. Give them a negative discount. A Windows XP user pays an extra 25%. A Windows 9x user pays 50% more.

Charging them a reconnection fee the second and subsequent time might be extra useful encouragement.

      Your discount idea might be good if reversed though: Give people 5% discount if they stay malware free for, say, three months. Maybe offering a higher discount after a longer period (10% after 12 months?). This would hopefully encourage careful behavior (behaviour is the key, not just software choice - someone who is fooled into runnin random crap that secretly sends out junk mail on a Windows box will be just as likely to run the Linux/Mac/what-ever equivalent) from the outset, and might be popular with the ISPs as a user retention policy (if you move, you have to wait the few months to get your discount back) if the discount is managed on a per ISP basis. In any case the ISP would have to be very careful to be sure that the traffic they see is a problem, that it is properly logged/recorded (being careful not to step on any privacy laws that may be in effect over there) and that there is some sort of appeals process in place in case the system somehow misidentifies the source of a problem, otherwise they might be opening themselves to compensation claims down the line - which is all starting to sound like far too much hassle to me...

    There is a responsibility by any user not to interfere with others. Being infected with a botnet is certainly one for this category. Not responding to warnings of infection is negating this and is abusive of others using the net. Why should users that interfere with others be tolerated?

    To simply say that a significant number of the people that have botnets don't know how to remove them, even after warnings is far to simplistic an excuse. The same can be said about their ability to pay to have them removed. Format C:/ is the lowest cost. Having a friend help remove personal data is the next and last 1 hour labour by the local shop to retrieve the personal data is not unreasonable. However this same group most likely don't have any significant personal data they can retrieve even for normal use as they have no idea where it is once they it save. They have never bothered or are incapable to learn the concept of directories or the concept of organizing their work. So they really don't have in a practical sense any personal data to recover. Am I heartless? No actually, just pragmatic.

    Why do those botnet infected people have any right to interfere with others wanting to share this net resource? Why is there a large group defending them seem to think there is no personal responsibility involved when going on the net? There is no right to interfere with me or is there? Be it simply by being a pest or anything else. I don't care what you do as long as it does not impact me within reason. We all share the net. We all generally have contracts with our ISP's with a code of conduct. I see no reason why those that don't head warnings to fix their systems shouldn't lose the privilege of access from that equipment.

    We qualify people for many things in our society. Most of those things revolve around protecting the rights of others. Just as a license is a privilege and requires a test, there are rules for bicycles, being an obnoxious drunk in public, etc. There is no right to thieve, assault, stalk, or be a public nuisance. A person with a botnet infection is part of interfering with others and they have no right to do that. But there certainly is a responsibility not to do that.

    But who is responsible to prevent it? Is it mine? Do I have to incur expense and time trying to keep these people from bothering and interfering with me? The practical aspects with today's technology says that at best it's only a partial solution anyway. So why limit only one approach? There is no rule that requires only one solution to deal with this menace that costs everyone time and money. Money reflected in everything from my time to the rates I pay for access to the net, on up the chain to the carriers.

    If I had my way there would be a fixed IP for all home connections. It is practical technically and is not a security problem to have one. Dynamic IP's offer negligible protection if any at all. A fixed IP certainly offers a measure ability for me to solve part of the problem. I see no reason why a system based on complaint or by discovery should not be used to cut these repeat offenders from using their own hardware to connect. They mostly have other options to get on the net if they fail to maintain their own equipment when notified. Where do any of you get off saying they aren't responsible for their own stupidity. So ok, If they have no obligation to others, then using that logic. There is no obligation to give them access or at least to that access from their infected equipment. They may get access from the library computer or other methods. They may still get on, just not using their trainwreck of a computer from home. All is then fair enough.
