Part of why the Y2K problem wasn't so bad is that a lot of people,
including me, worked hard to fix a lot of systems beforehand.

They ended up getting scorn instead of credit for their work.

I guess that's better than a world-wide collapse :)
I hear ya, I was also part of the effort to make sure it was a non-
event. Next time, I say we let disaster happen, and become heroes by
saving the world...

Never mind, we'll still get scorn because we didn't prevent it.

Sigh. Don't see how we can win...

One in 200? I should hope it's *considerably* less than that.

Why is this a surprise? Look at the number of people who argue
against vaccinations because "the disease they prevent doesn't occur
that often".

I got one of those calls from someone that they were a Microsoft Tech. That
they were alerted to the malware in my computer. That it was done without my
knowledge. He wanted to fix it for me. No, I did not fall for it. For one
thing, Microsoft Techs don't call you. You call them. I was not born
yesterday!!

Tech support even told me not to change the factory password when
I was on the phone with them once. Change it anyways.
Which company was that? ...If you're willing to say :)

That story sounds to me like a good reason to avoid that company's
routers.

Yeah. We can't even hope for a plain old zero-sum game :)

Sorry, left out a decimal point. It should be less than 1 in 2000.
This is based on old data, assuming there are 1 billion computers in the
world & using the estimated number of computers that were infected in
Nov 11. There are significantly more computers than that now &
supposedly 100,000 or so fewer infected computers, which would reduce
the odds even further that any particular computer is infected.

No names but it's one of the top selling wireless routers that I recently
bought.
It may have been just that one tech support person's slight oversight.

Yes.

just will not do name to IP address resolution.
No. They will be sent to probably wrong IP!

No. The DNS Servers were shutdown thus the DNS calls will go unanswered.

At least one of the big ISPs supposedly [a] will be
redirecting those DNS requests to its own servers.

Which in some ways raises more concerns than it solves...

Not true. The "FBI's DNS Servers" were shutdown. The rest of the world's DNS servers
continue to work AOK.

A decent ISP response, but basicly unneeded except for customer satisfaction.

FYI, David H. Lipman is quite knowledgeable in this area and is well
aware that it was the FBI-run DNS servers that were being shut down. I
think if you review the context of David's statement above, you'll
clearly see that.

The same iscreant who had ESTDomains created the DNSChanger trojan. The
DNSChanger trojan (sometimes protected with a rootKit) would alter the DNS
Table of computers and poorly or insecure SOHO Routers.

The malicious DNS Servers were setup in the following ranges...
93.188.160.0 ~ 93.188.167.255
77.67.83.0 ~ 77.67.83.255
85.255.112.0 ~ 85.255.127.255
213.109.64.0 ~ 213.109.79.255
67.210.0.0 ~ 67.210.15.255
64.28.176.0 ~ 64.28.191.255

The US FBI took over DNS Servers at those address spaces. It is those that
were shutdown.

If a victim had been infected with the DNSChanger trojan then their IP
addresses in the DNS Table woould have been altered to addresses within that
space. If a victim had not corrected their respective systems prior to the
FBI's takedown of the servers then those who had been using them would no
longer perform name to IP address resolution and then all DNS calls from an
affected computer would have gone unanswered.

From the POV of an infected/affected user, all other DNS servers on the 'net
is a moot point.
