Zombie Report By ISP
twitter writes "Information Week has a summary of a report by Prolexic detailing Zombie activity by ISP, country and population statistics. AOL, the largest provider, had the most zombies but lower rates than others. Fourth largest Earthlink was not in the top 20. The information is gathered from hundreds of customer sites." From the article: "Weinstein went on to say that Prolexic's numbers were actually good news for AOL. 'It's a demonstration that the tools we provide are keeping members safe. Our very aggressive actions -- we provide anti-virus, anti-spyware, and firewall services to our users -- make them measurably safer than those on other ISPs.'"
AOL spins the report as good news because they claim a low rate of 0.54% zombie machines per million subscribers...yeah but...
They are basing that on 21.7 million total subscribers. I wonder what their rate would be if they only counted broadband subscribers?
The NSA: The only part of the US government that actually listens.
Now, perhaps we can start putting some pressure on the bad ISPs to clean up their networks on the basis of their successful peers.
I'm really sick of everyone in the world looking down on me as soon as they find that my IP is on a Comcast block.
AOL, the largest provider, had the most zombies
Sometimes jokes just write themselves...
There is nothing more practical than a good abstract theory.
we provide anti-virus, anti-spyware, and firewall services to our users
BUT WAIT! There's more!
If you act now, we'll throw in ANOTHER anti-virus service at no extra charge! All this for only 89.95!
Okay, I'm not supposed to do this, but I'll personally add another EXTRA anti-spyware monitoring system AND take off 50 bucks from the retail price!
All this and more for only 3 easy payments of 39.95!
1. Participation in Distributed Denial-of-Service attacks
2. EATING BRAINS
But you will block 21 million legitimate users too. If that is acceptable, I don't really want to have anything to do with your company.
End users just *don't care*. This is why there are botnets. Because, although their owned boxen are f-ing with the rest of the internet, it doesn't affect them - a selfish luser attitude, why should they bother virus/trojan scanning their boxen?
I wish ISPs (victims and hosting) would hold the lusers responsible for this - I think criminal negligence would be an appropriate charge. I for one look after my gentoo linux boxen and keep them patched.
No amount of firewalls, switching to Mac or Linux, or anything else will stop people from having their computers taken over at the end of the day. Stupid users will always find a way to get infected dispite the best protection available.
Operating a computer should be like operating heavy machinary. You need to pass a test that says you're qualified to do it. Don't want to take the time to learn how to properly use a computer and avoid being just another zombie PC sending me emails about lowering my car payments or free nude pics of celebrities? Then don't use a computer at all.
If you think this is a little irrational, just remember that the financial damages caused by computer viruses are probably in the billions of dollars every year. Imagine how much trouble could be prevented.
The other thing about AOL's dialup service is that they buy modems from local ISP's in areas where they don't operate central hubs. I used to work for one such ISP that contracted to AOL. We were very proactive about protecting customers, etc.
So a lot of the AOL crowd having good numbers may very well be local ISP's that are taking good care of their own customers, and just happen to contract out to AOL on the side

You know those underlined bits in the summary at the top of this page? They're called hyperlinks, and you can click on them... try clicking on the second one.
If eBay, playboy.com and espn.com blocked AOL users until AOL got rid of their zombies AOL would make absolute certain that the problem would be solved within 48 hours.
They had the most zombies but a lower rate than others. They spin this as good.
But according to the post, Earthlink (the fourth largest provider) wasn't even in the top 20, implying that their zombie percentage is far lower than AOL's.

The Prolexic Zombie Report

So (making #s up) if AOL is 10% of all attacks, and 100 million machines, they have .1 percent per million. But if Joe's ISP has 5% of all attacks, and only 5 million machines, they have 1.0 percent per million.
AOL has twice as many attacks total, but compared to their user base Joe's rate is ten times as high.
Warning: Apple/Nintendo fangirl. Likes her electronics cute & cuddly. May be rabid.
"That's three or four times as many attacks per million subscribers," Weinstein argued. "The numbers show that AOL members are significantly less likely to have been compromised by a zombie. This is actually good news for our users."
Picture that you're a script-kiddie botnet owner looking for more zombie systems. You have a program that someone provided to you that scans netblocks for systems vulnerable to hundreds of various buffer overflow attacks. You get to pick what netblocks the scanner runs on.
Which would you pick:
1. AOL dialup netblocks, where the user's average 48 K/bps connection takes an average of 1 minute to scan and provides you with a wimpy 48 K/bps of DDoS power
2. Comcast Cable Modem netblocks, where the user's average 384 K/bps upstream bandwidth takes an average of 6 seconds to scan and provides you with a beefy 4,000 K/bps downstream DDoS power.
The numbers quoted above should be accurate enough to get the point. AOL hosts take far longer to compromise and provide far less "bang for the buck". No wonder they're compromised a smaller percentage of time.
I'm a big tall mofo.
Except that it wasn't just an appliance, was it? It was a bug ridden piece of manure that was delivered with known defects, to people who by and large don't have the wherewithal to work around those defects.
This is Microsoft's fault, plainly. Not the poor bastards who were taken in.
Remember: most zombies involved in a DDoS attack are simply opening a connection, sending a malformed request then closing the connection. They aren't playing FPS games or downloading porn, so high bandwidth isn't really required. What is required is a vast diversity in IP address so that the firewall and server are overwhelmed trying to process every incoming request.
The blurb says Earthlink is not in the top 20. Mindspring, listed as 17th most infected, is Earthlink.
Actually, AOL's "ISP" is AOL Transit Data Network (ATDN), a related company. They're a "tier 1" provider, and they communicate directly with other tier 1 providers: AT&T, MCI, Level(3), Verio, GBLX, C&W, Verizon, etc. They're the guys who own the big continent- and ocean-spanning fiber optic networks.
"ISP" usually refers to something more customer-facing than the tier 1 providers.
