Microsoft Discloses Government Backdoor on Windows Operating Systems

Microsoft may have inadvertently disclosed a potential Microsoft backdoor for
law
enforcement earlier this week. To explain this all, here is the layman term of
a backdoor
from Wikipedia:
A backdoor in a computer system (or cryptosystem or algorithm) is a method of
bypassing normal authentication, securing remote access to a computer,
obtaining access
to plaintext, and so on, while attempting to remain undetected. The backdoor
may take
the form of an installed program (e.g., Back Orifice), or could be a
modification to an
existing program or hardware device.
According to an article on 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
that
ships with Windows."
Not a big deal until you keep reading: "Although Microsoft is reluctant to give
out details
on its botnet buster - the company said that even revealing its name could give
cyber
criminals a clue on how to thwart it"
Stop the press for second or two and look at this logically: "users who have
installed the
Malicious Software Removal tool" followed by " Microsoft is reluctant to give
out details
on its botnet buster - the company said that even revealing its name could give
cyber
criminals a clue on how to thwart it", what? This is perhaps the biggest gaffe
I've read
thus far on potential government collusion with Microsoft.
We then have the following wording: "Microsoft had not previously talked about
its
botnet tool, but it turns out that it was used by police in Canada to make a
high-profile
bust earlier this year." 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."
Remember a "Malicious Software Reporting Tool" is a lot different from a
"Malicious
Software Removal Tool". Understanding networking, computing, botnets, let's put
this
concept into a working model to explain how this is nothing more than a
backdoor. You
have an end user, we'll create a random Windows XP user: Farmer John in North
Dakota.
Farmer John in North Dakota uses his machine once a week to read news, send
family
email, nothing more. He installed Microsoft's Malicious Removal Tool. Farmer
John's
machine becomes infected at some point and sends Microsoft information about
the
compromise: "I'm Farmer John's machine coming from X_IP_Address".
A correlation is done with this information and then supposedly used to track
where the
botnet's originating IP address is from. From the article: "Analysis by
Microsoft's
software allowed investigators to identify which IP address was being used to
operate the
botnet, Gaudreau said. And that cracked the case." This is not difficult,
detect a DST
(destination) for malware sent from Farmer John's machine. Simple, good guys
win,
everyone is happy.
The concept of Microsoft's Malicious Software Removal tool not being a backdoor
is
flawed. For starters, no information is ever disclosed to someone installing
the Windows
Malicious Software removal tool: "Windows will now install a program which will
report
suspicious activity to Microsoft". As far as I can recall on any Windows
update, there has
never been any mention of it.
"But this is a wonderful tool, why are you being such a troll and knocking
Microsoft for
doing the right thing!". The question slash qualm I have about this tool is I'd
like to know
what, why, when and how things are being done on my machine. It's not a matter
of
condemning Microsoft, but what happens if at some point in time Microsoft along
with
government get an insane idea to branch away from obtaining other data for
whatever
intents and purposes?
We've seen how the NSA is allowed to gather any kind of information they'd like
(http://www.eff.org/issues/nsa-spying),
we now have to contend with Microsoft attempting to do the same. Any way you'd
like to
market this, it reeks of a backdoor: (again pointing to the definition) A
backdoor in a
computer system ... is a method of bypassing normal authentication, ...
obtaining access
to ... , and so on, while attempting to remain undetected. There's no beating
around the
bush here on what this tool is and does.
This is reminiscent of the 90's with the NSA's ECHELON program. In 1994, the
NSA
intercepted the faxes and telephone calls of Airbus. What resulted was the
information
was then forwarded to Boeing and McDonnell-Douglas in which they snagged the
contract from under Airbus' feet. In 1996, the CIA hacked into the computers of
the
Japanese Trade Ministry seeking "negotiations on import quotas for US cars on
the
Japanese market". Resulting with the information being passed off to "US
negotiator
Mickey Kantor" who accepted a lower offer.
As an American you might say "so what, more power to us" but to think that any
government wouldn't do it to its own citizens for whatever reason would be
absurd.
There are a lot of horrible routes this could take.
What happens if slash when for some reason or another the government decides
that you
should not read a news site, will Microsoft willingly oblige and rewrite the
news in
accordance to what the government deems readable?
How about the potential to give Microsoft a warrantless order to discover who
doesn't
like a President's "health care plan", or who is irrate and whatever policy;
Will Microsoft
sift through a machine to retrieve relevant data to disclose to authorities?
That doesn't include the potential for say technological espionage and gouging
of sorts.
What's to stop Microsoft from say, mapping a network and reporting all
"non-Microsoft"
based products back to Microsoft. The information could then be used to say
raise
support costs, allow Microsoft to offer juicier incentives to rid the network
of non MS
based products, the scenarios are endless.
Sadly, most people will shrug and pass it off as nothing. Most security buffs,
experts, etc.,
haven't mentioned a word of it outside of "the wonderful method to remove,
detect,
botnets!" and I don't necessarily disagree it's a unique way to detect what is
happening,
but this could have been done at the ISP and NSP level without installing a
backdoor.
Why didn't law enforcement approach botnets from that avenue? Perhaps they
have, this
I'm actually certain of which leads me to believe this is a prelude of
something more
secretive that has yet to be disclosed or discovered.

More on Microsoft's *Potential* Government Backdoor
Thursday, May 1st, 2008 @ 7:21 am | Privacy, News
http://www.infiltrated.net/?p=92
After reading through Microsoft's comments repeatedly yesterday, I cannot come
to the
conclusion that Microsoft's "Malware Removal Tool" is not some form of
backdoor.
Their comments in the initial article are extremely disturbing and anyone using
a
Microsoft product should now be extremely weary about downloading new updates
if
even deciding to continue using Microsoft at all.
So let's take a look at the top botnets. Srizbi, Bobax, Rustock, Cutwail,
Ozdok, Nucrypt,
Wopla, Spamthru, Storm, Grum, Onewordsub; These are the top as reported by
Secure
Works.
(http://www.secureworks.com/research/threats/topbotnets/?threat=topbotnets)
Guess what, eight out of eleven are all encrypted. Not that big of a deal until
you decipher
what Microsoft stated in their original quotes in correlation to some facts.
>From the article: Microsoft security experts analyze samples of malicious code
>to capture
a snapshot of what is happening on the botnet network, which can then be used
by law
enforcers, Cranton said. "They can actually get into the software code and say,
.Here's
information on how it's being controlled.'"
Perhaps Microsoft could clarify how exactly are they doing what they do, more
importantly, what information is being sent over the wire and to whom. Are they
now
breaking code as well. Did the botnet authors go through the steps of
encrypting code. We
know for a fact that traffic being sent from a compromised host to a controller
is
encrypted, so what is Microsoft analyzing. What COULDN'T Microsoft have gained
from getting code for analysis say by working along with Symantec or someone
else.
Now before you shoot off an answer like "the code doofus, they're analyzing the
code!",
think about it again. If they're in it to analyze solely the code, they could
have worked
with AntiVirus vendors for samples as opposed to putting a tool on your machine
which
collects YOUR DATA and sends it off to who knows where. A law enforcement
agency,
or team Microsoft.
I'll pause on this for now. How about the validity in stating: "Botnet Operator
tracked via
IP". How legitimate is this argument given the fact (not presumption) that IP
is a horrible
identifier. Let's put this in a practical example. Farmer Joe in Nebraska is
using a DSL
connection that it always on. He uses Windows XP and doesn't know what a
Windows
Update is so he's never used it. His computer is compromised, a botnet
controller is
installed and attacks are launched from Nebraska. The attacker sanitized Farmer
Joe's
machine to erase his tracks using multiple wipes with perhaps PGP. The end.
For any business or law enforcement agency to claim they can track down via an
IP
address, perhaps they've skimmed on the fact that there are far too many open
WiFi
hotspots in the world to conclusively narrow a fact. We have an assumption that
an
attacker is behind 10.10.10.159. Can we see them? No. All we know is the
address. Being
I've used a private address, I won't bother diving into "but he came from ISP X
in
Nebraska." Irrelevant. What you have is a fishing expedition.
/ SNIP
For more on this false sense of ID-via-IP: Well, let me ask you you think
171.70.120.60
is. I'll give you a hint; at this instant, there are 72 of us.
Here's another question. Whom would you suspect 171.71.241.89 is? At this point
in
time, I am in Barcelona; if I were home, that would be my address as you would
see it,
but my address as I would see it would be in 10.32.244.216/29. There might be
several
hundred people you would see using 171.71.241.89;
/END SNIP
I implore you to read a NANOG thread
http://readlist.com/lists/trapdoor.merit.edu/nanog/6/33246.html
Professionals know, IP is an inaccurate identifier so why does it seem that
Microsoft
along with LEO are relying on this. Makes a great baseline sure, but is
certainly ripe
for abuse
Again, please understand what I am stating, this is "not to say that its a
horrible idea", its
a start, a baseline - but not a definitive measure of determining who is
controlling a bot,
who created the botnet, etc.
Looking at past history, unfortunately you have the tinkerers; so what happens
to an up-
and-coming "security" buff who is getting into the field and stumbles upon a
botnet. Sure
he was moronic to join an irc channel filled with bots, sure he was idiotic in
downloading
the code for the sake of learning. Fact is he might have. Guess what will
happen to him
when a Law Enforcement Agency raids his house? Guess what will happen when that
agency needs funding for a new uber Cyber(buzzword)Crime fighting department.
You
guessed it. Hey "Up-and-coming security buff..." Kiss your terminal goodbye,
and from
here on out, your dreams of becoming the next Bruce Schneier will be close to
non-
existent. It happens.
Anyhow, re-emphasizing... Shame on Microsoft for forwarding your data without
telling
you. Shame on Microsoft for not asking you if you wanted to "PARTICIPATE" in
sending data. Shame on Microsoft for not explicitly stating: The data we are
sneaking off
your computer will be sent to government agencies of our choice. Its a horrible
practice
and a damaging breach of trust. Their action worries me as a security
professional, will
they ever scour for data for profit. Why not, no one would notice or care
anyway.
