Sorry, conspiracy buffs, there's no Windows "back door"

By | April 29, 2008, 4:53pm PDT

Summary: The Techmeme echo chamber has decided to whip up a controversy today with a new variation on an old story. The latest claim is that Microsoft has built a secret “back door” into Windows and has been handing over the the keys on a USB flash drive designed exclusively for law enforcement. It takes about five minutes of investigation to uncover the real truth. No, there is no back door. And no, these aren’t super-secret hacking tools that give the police an unfair edge. After all, the bad guys developed their own version of these tools years ago. I’ve for the details in my full report.

Techdirt’s Mike Masnick is usually pretty reliable, but he completely blew it today, hitting the publish button on one of the sloppiest, most inflammatory stories I’ve seen in a long time:

Microsoft Gives Vista Backdoor Keys To The Police

It’s long been assumed that Microsoft has built in various “backdoors” for law enforcement to get around its own security, but now reader Kevin Stapp writes in to let us know that the company has also been literally handing out the keys to law enforcement. Apparently, they’re giving out special USB keys that simply get around Microsoft’s security, allowing the holder of the key to very quickly get forensic information (including internet surfing history), passwords and supposedly encrypted data off of a laptop. While you can understand why police like this, the very fact that the backdoor is there and that a bunch of these USB keys are out there pretty much guarantees that those with nefarious intent also have such keys.

OK, now go read the linked story from the Seattle Times. There’s not a word - not one word - about back doors or encryption. Sadly, the usual suspects in the Techmeme echo chamber are whipping the inaccuracy around the infield at major league speeds. CrunchGear says Microsoft has “developed a thumb drive that helps Johnny Law quickly extract information, encrypted or otherwise, from computers.” And Valleywag talks about “a USB dongle that plugs into a computer, bypasses any Windows passwords or encryption, and quickly downloads sensitive data such as your Web browsing history.”

I’ve heard of jumping to conclusions, but these are some truly giant leaps.

All three stories reference the same Seattle Times story, which never says or even implies that the tools on this USB drive could break any sort of encryption, including Microsoft’s BitLocker Drive Encryption. In fact, these tools have been distributed since last June and were actually discussed three weeks ago in a Microsoft press release published April 8:

At LE Tech today, we will also be talking about the tools we are providing to law enforcement. For example, our security team in the Asia-Pacific region, led by senior investigator Anthony Fung, developed the Computer Online Forensic Evidence Extractor, or “COFEE.” The tool provides investigators with a means to easily and quickly extract “live” data from a suspect’s computer at the point of seizure, before turning it off.

COFEE, a preconfigured, automated tool fits on a USB thumb drive. Prior to COFEE the equivalent work would require a computer forensics expert to enter 150 complex commands manually through a process that could take three to four hours. With COFEE, you simply plug into a running computer to extract the data with the click of one button –completing the work in about 20 minutes.

What Microsoft has done, according to this story, is to repackage some of the standard tools used by computer forensics experts when they seize a computer as evidence. So instead of a computer forensic technician having to perform a bunch of time-consuming tests manually, he or she can use these automated tools to capture information in a few minutes.

For anyone who is ill-informed enough to think that these tools are going to land in the hands of bad guys, I have some bad news. They’re way ahead of you. The community-developed USB Switchblade has been around since at least September 2006. And as security expert Jesper Johansson points out, it has an impressive feature set:

Basically, these tools make it really easy for just about anyone to exploit people who leave their USB ports unprotected. For example, Switchblade can dump the following:

  • System information
  • All network services
  • A list of ports that are listening
  • All product keys for Microsoft products on the computer
  • The local password database
  • The password of any wireless networks the computer uses
  • All network passwords the currently logged on user has stored on the computer
  • Internet Explorer®, Messenger, Firefox, and e-mail passwords
  • The Local Security Authority (LSA) secrets, which contain all service account passwords in clear text
  • A list of installed patches
  • A recent browsing history

All of this goes into a log file on the flash drive, and takes about 45 seconds.

Forensic technicians working for law enforcement are simply hackers with white hats. They know, just as the bad guys do, that if you have physical possession of a computer, you can pull the data off the hard drive and you can decrypt local passwords. There’s nothing new involved in the story that’s getting all the publicity today, and there is certainly nothing to suggest that there’s a “back door” involved.

In fact, if this rather unremarkable collection of Microsoft-developed hacker tools actually did contain anything new, I would certainly expect that the highly vocal security community would have said something. If there turned out to be a back door in BitLocker or any other form of encryption, the real experts would be publishing the results. But they haven’t said a thing, because there isn’t a story here.

Let’s see how long it takes for the corrections to begin appearing. I’m not holding my breath.

Update: Ben Romano of the Seattle Times, who wrote the original story, has published an updated post (Looking for answers on Microsoft’s COFEE device) that also tries to clear away some of the FUD. Ben’s whole post is worth reading, but if you’re too busy, here’s the conclusion: “It sounds to me like the device doesn’t do anything that a trained computer forensics expert can’t already do. This just automates the execution of the commands for data extraction.” In a later update, he adds: “Via email, a Microsoft spokeswoman said COFEE is a compilation of publicly available forensics tools, such as ‘password security auditing technologies’ used to access information ‘on a live Windows system.’ It ‘does not circumvent Windows Vista BitLocker encryption or undermine any protections in Windows through secret “backdoors” or other undocumented means.’”

Exactly.

All you've really said is that law enforcement doesn't need a back door because MS' encryption is easily broken. You've presented no evidence on the back door issue one way or the other.

Don't know whether MS has back doors in Windows or not, and your story doesn't provide any further enlightenment thereon.

Ed Bott 29th Apr 2008
The story as reported was inaccurate and sensational. If there was a back door that had been distributed to more than 2000 police agencies all over the world, do you think it cold remain a secret? Please.
but kept it from the hackers and crackers of the world as well.

Sure, the best minds in security missed it, and use the equivalent of stick and stones for tools, while barney fife just uses the built in back door via his handy usb key.

A backdoor - who really knows
deaf_e_kate 30th Apr 2008
Your blog title is misleading as you cannot prove it one way or the other, its speculation.

If there is one, it would only be given to the organisations that know how to keep secrets.

To say, with conviction, that there is no backdoor is wrong unless you've had access to the code and have the skills to interpret it.

Would i trust a MS spokesperson to confirm a "ya" or "nay" to the presence of a backdoor? No, i wouldn't.

And for what it's worth, the author of the original piece in the Seattle Times agrees with me.

And just to add...
Ed Bott 1st May 2008
Back Orifice required that a server be installed on the target machine, after which it could be controlled remotely from an administration console. It's the same technique that the current crop of Trojans use. It doesn't take advantage of any "back door" in Windows. It relies on tricking the victim into installing a piece of software that in turn opens the front door.

As for my headline being in error... The original story in Techdirt still has a headline talking about Microsoft handing out USB keys and opening a "backdoor" for law enforcement. I have established to my satisfaction that no such thing is going on. The story as published in Techdirt is wrong.

Ed Bott 29th Apr 2008
With physical access, it takes very little effort to break into any box that uses normal security.

Of course, if you have full drive encryption using BitLocker or something similar, you're going to have a very hard time breaking in. Or perhaps you'd care to show me one example of anyone, anywhere, who has cracked BitLocker?

paper that proves windows encryption algorithms are weak?

Windows uses FIPS certified implementations of standard algorithms. AES, ECC, RSAm SHA...

The Chinese papers discuss collisions for the most part in the hashing algorithms such as SHA.
The 5 Chinese algorithms are based on their own IP and ECC currently but sadly the Chinese do not publish their algorithms for evaluation.

As far as prand for Windows is concerned it is one the best around with a fairly substantial entropy sources.
Now for the really serious random numbers a HW trand source can be plugged into Vista and you can party down.

As they will gently ask you to provide the password for unlocking the drive.....

The nice part of these tools is that the PC actually needs to be on and preferably you're logged in as they will kindly ask you. Not complying will ensure that you can handle the laptop over for a period of time, probably enough time to have the number crunchers crack most available encryption.....

NSLs and clones
engrmerc 5th May 2008
Obviously, you do not know what a 'national security letter' is, or the fact that you can remove a hard drive, clone it and put it back in less than a couple of hours. Then having physical access to the original computer for the purpose of decrypting it's contents.

Honestly, it's not the NSA you have to worry about, anything the public has, they probably can already break into, it's the crazy fed neighbor who doesn't like your dog or the height of your hedges or the fact you called the local cops on his snot nosed brat or you dated his sister for two weeks that is the real problem.

And thanks to the executive branch, you won't know any of this until they seize your bank accounts, your home and arrest you at work.

Altotus 4th May 2008
Yea and how not just that but study the design of what is kept and how where in relation to the use of USB "key" . Does this reveal the intent of design that allows such collection to take place in the first place. Would you not find this to be inherent by deliberate design to be insecure. To say that this is accidental is well LOL in fact rof. Well I doubt if Ms is handing a backdoor key to a bunch of detectives anyway they could not be responsible for the damages caused when every crook in the world ends up with it. I thought that many already knew that MS systems collects many types of user data and stores it away in less visible places. This is as much access as a law enforcement officer needs a back door would be an excession and lead to immediate abuse.

Not protecting me...
srobtjones@... 30th Apr 2008
...but perhaps suspecting me or others of any number of things.

Most LE types are upstanding, decent, hard-working professionals. Depending on which agency or department they work for, the case load for computer forensics people can range from 60 % to 95% kiddie porn.

To be sure, this is disgusting, and needs to be prosecuted. Please spare me, however, the platitudes that by doing this they are protecting me, when they are not. As I do not engage with kiddie porn in any way, this does nothing for me personally.

The people doing kiddie porn cases generally are not the ones involved with the types of cases where OS backdoors would even need to be used. These cases are pretty straight forward in nature and usually the government has enough evidence to get a plea agreement.

Yes, LE types have a tough job, especially the non-computer cops. The kiddie porn coppers have a very rough job, but I do not see how it affects me directly. I would rather that more moeny be budgeted for narcotics and murder investigations than for child porn. Of course, that's just my opinion.
One of the 1st thing the police do when there is a murder is research the victim's computer for contacts, email that might point to a suspect. If a suspect is targeted and warrant issued then the suspects computer is searched.
Also, where do you think the narcotics trafficers keep their contacts and financial info?

They didn't claim innovation. They claimed ease-of-use benefits. Selling new televisions pre-assembled is not innovative, but it sure makes it easier for me to use.
It isn't meant to "wow" us but the law enforcement industry which it did. The world's law enforcement is not yet up to dealing with the sophistication and scale of cybercrime. This little gathering of tools helps their cause so if they don't complain either should we. Sometimes packaging is everything. A failed interpreted language was renamed to Java and bingo.

srobtjones@... 30th Apr 2008
I agree that this article confirms nothing. It denies much, however, and methinks M$ uses ZDNET to protest to much...

Having trained with military intelligence and government LE experts, I can assure that every version of Windows up to VISTA has at least one "back door". How you define "back door" is the real argument.

Some define NSAKEY as a back door. Others consider the myriad of security holes to be back doors. Again, it comes down to symantics.

Regarding VISTA, I have no doubt that there is at least one back door in VISTA, based upon historical precident alone. I know that this too proves nothing; however, I am not misleading people by claiming that a back door does not exist.
