And you know me this well to infer it's stirring up emotions. I call it
raising awareness. You have your interpretation of what you read, I have
mine. Is yours wrong Paul.

This is what you call "raising awareness".

"Microsoft may have inadvertently disclosed a potential Microsoft backdoor for
enforcement earlier this week. "

Of course, with the weasel words "may have", "inadvertently" and "potential",
you can always claim you never really said that, but you know exactly what the
reader will take away from that headline - "What??? Microsoft installed a
backdoor on my computer????"

You then quote PC World - "The software vendor is giving law enforcers
access to a special tool that keeps tabs on botnets, using data compiled from
the 450
million computer users who have installed the Malicious Software Removal tool
ships with Windows."

Note that the botnet tool is "a special tool that keep tabs on botnets" and
that it "use[s] data compiled from the 450 million computer users....."

Now we know, first of all, that the MSRT doesn't even send data unless you have
an infection (and that functionality can be disabled.) Secondly, we know that
the botnet tool "uses" data compiled from the use of the MSRT.

From this you get "Microsoft has installed a backdoor on your computer!!!"

Then you make this amazing leap of "logic".

"So again, thinking logically at what has been said so far by
Microsoft; "We have a tool called Malicious Software Removal tool...", "we
can't tell
you the name of this tool since it would undermine our snooping...", "it's been
used by
law enforcement already to make a high-profile bust earlier this year."

So, in one "sentence" you tie the MSRT to the botnet buster and go from "it
sends data" to "it spies on you". Nice try, but you're not fooling anyone
except fools.

BTW, a backdoor program is something that allows me to access your computer
without your knowledge any time I want to, not a program that sends me
information whenever you choose to run it *if* you choose to send it. Again,
nice try, but you're not fooling anyone except fools and conspiracy theorists.

Next you manage to tie the MSRT to the NSA, Echelon, AT&T wiretaps,
eavesdropping and other supposed nefarious activities.

But you're not trying to stir up emotions - no - just "raising awareness".

It is Microsoft's fault for not being honest period no ifs ands or buts.
Please give us your professional correlation of the article. Information
obtained from MSRT was used to track botnet hunters in cahoots with another

I don't know the details of what Microsoft is providing LE from MSRT. Neither
do you. That is precisely my point. That isn't stopping you from making wild
claims, though.

Here's one possible use.

Microsoft correlates the data sent from MSRT. They notify law enforcement that
they are seeing a recent trend of 150,000 computers infected with a certain
malware. It opens port x, communicates using protocol y and talks to the
following IP addresses (C&Cs). They provide LE with a tool that is a botnet
hunter that knows what traffic to look for, what ports to look on, what
protocols are being used and where the C&Cs are. All that information was
obtained from the data received from MSRTs reporting in from all over the world.

LE then uses that tool to set up monitoring of those specific ports, protocols
and C&Cs, begins gathering data and eventually busts the botmaster.

Now, how has this exposed you personally? Revealed your IP? Invaded your
privacy? Created a backdoor on your computer?

Yes, their web page (I don't see any EULA) states that they don't collect
personally identifiable information. Furthermore, the botnet tool is a
separate tool. The page also states that after the tool is run, it deletes
itself. So, when you are infected with something, the tool will detect and
clean it *and* send some information about the infection back to M$.

Can you please find this page. I showed you mine show me yours or just STFU
for now, otherwise the "my cojones are bigger than yours" becomes redundant
nonsense. EOS

Please review KB890830 for the list of malicious software that the current
version of the tool is capable of removing as well as usage instructions. Also,
please be aware that this tool reports anonymous information back to Microsoft

"Reporting infection information to Microsoft
The Malicious Software Removal Tool will send basic information to Microsoft if
the tool detects malicious software or finds an error. This information will be
used for tracking virus prevalence. No identifiable personal information that
is related to you or to the computer is sent together with this report."

"Reporting component
The Malicious Software Removal Tool sends information to Microsoft if it
detects malicious software or finds an error. The specific information that is
sent to Microsoft consists of the following items:
The name of the malicious software that is detected
The result of malicious software removal
The operating system version
The operating system locale
The processor architecture
The version number of the tool
An indicator that notes whether the tool is being run by Microsoft Update,
Windows Update, Automatic Updates, the Download Center, or from the Web site
An anonymous GUID
A cryptographic one-way hash (MD5) of the path and file name of each
malicious software file that is removed from the computer

If apparently malicious software is found on the computer, the tool prompts you
to send information to Microsoft beyond what is listed here. You are prompted
in each of these instances, and this information is sent only with your
consent. The additional information includes the following:

"Q3. How can I disable the infection-reporting component of the tool so that
the report is not sent back to Microsoft?

A3. An administrator can choose to disable the infection-reporting component of
the tool by adding the following registry key value to computers. If this
registry key value is set, the tool will not report infection information back
to Microsoft.
