Microsoft Acquires Winternals and Sysinternals
SJasperson writes "In a move that will be good for Redmond but may have consequences for the rest of us, Microsoft has acquired Winternals and Sysinternals. This gives them well-known developers Mark Russinovich and Bryce Cogswell as well as dozens of well-loved and much-praised utilities, both commercial and freeware. Though Mark says on his blog that the Sysinternals site will remain 'for the time being,' this would be a good time to download the latest version of essential Windows tools like Process Explorer before they can go mysteriously missing or be locked up behind the wall of Windows Genuine Advantage." -

WMF Flaw not a Backdoor
koro666 writes "In a blog post, Mark Russinovich from SysInternals responded to the allegations made by Steve Gibson labeling the flaw as an intentional backdoor. It seems that the hype was about Steve's discovery that the code would only be executed if the size of the metafile record was deliberately tampered with, which is not the case. The technical details are explained in his post." -
Windows vs. Linux Study Author Replies
Last week you submitted questions for Dr. Herb Thompson, author of the latest Microsoft-sponsored Windows vs. Linux study. Here are his answers. Please feel free to ask follow-up questions. Dr. Thompson says he'll respond to as many as he can. He's registered a new Slashdot username, FFE4, specifically to participate in this discussion. All others claiming to be him are imposters. So read, post, ask, and enjoy. 1- A better way of putting it:
by einhverfr
It seems that your study attempted to simulate the growth of an internet startup firm on Windows or Linux. One thing I did not see in the study was a good description of assumptions you made. What assumptions were made in both the design of the requirements and the analysis of the data? What limitations can we place on the conclusions as a result of these assumptions?
Dr. Thompson
This is a really important question. I think there are two sections of the study: the assessment methodology and then the experiment we undertook to illustrate how to apply that methodology. I'll answer the assumption question for both parts:
Methodology - For the methodology, we wanted to provide a tool that organizations could use and apply their own assumptions. Maintaining a system is all about context; some environments favor Linux, others Windows. The question is, how do you know what's likely to be the most reliable (which includes manageable, secure and supportable) solution for your environment? We proposed a methodology a recipe - that looks at a solution in its entirety instead of just individual components. Policies like configuration control vary from organization to organization and to get something that's truly meaningful in your environment, the methodology needs to be carried out in your context. Enterprise customers can and should do this when they are about to trust their critical business processes to a platform. That said, the basic assumptions of the methodology are that patches are applied at 1 month intervals and that business needs evolve over time. How those business needs evolve depends on the scenario you're looking at (in our experiment we looked at ecommerce for example). The methodology doesn't cover steady state reliability, meaning the uptime of a system that is completely static. While this is important, our conversations with CIOs, CTOs, CSOs and IT folks lead us to believe that this was a smaller contributor to pain in a dynamic environment. In an appliance for example, though, steady state reliability is king, and I think an important limitation of this methodology is that we don't capture that well, and I think it's amazingly difficult quality to measure in a time-lapse way.
The purpose of the experiment was to illustrate how to apply the methodology and to begin to get some insights into some of the key model differences between two platforms. For the experiment we picked the ecommerce scenario, for no other reason than there has been a clear shift in how ecommerce sites have serviced their customers in recent years moving from static sites to personalized content. Some specific assumptions were:
* The transition from a basic purchasing site to a personalized portal based on order/browsing history takes place over a one year period.
* The period we looked at was July 1st, 2004 to June 30th, 2005 (the most recent full year at the time of the study).
* A configuration control policy exists that mandates OS version but not much else meaning administrators had fairly free rein to meet business requirements.
* All patches marked as critical or important supplied by the vendor are applied.
* We assume the system to be functioning if the original ecommerce application is running and meets some basic acceptance tests (same for both platforms see Appendix 1 of the report) and the new installed components are also running.
* To add new capabilities, we use leading 3rd party components as opposed to building custom code in-house.
* The business migrates operating system versions at the end of the one year period to the latest versions of the platform.
* The administrators that participated in the experiment reflect the average Linux (specifically SuSE) and Windows administrators in skill, capability and knowledge. While this was strived for, it's important to recognize the small sample size in drawing any conclusions from the data.
As far as limitations, the experiment looks at one specific case with a total of six administrators. I'd love to have done it with a hundred admins on each side on a wide range of business requirement scenarios and my hope is that others will do that and publish their results. Our experiment, however, shows that for this particular, clearly documented scenario, experienced Linux Admins had conflicts between meeting business needs and a recommended best practice like not introducing out-of-distribution components. If one is aware of potential conflicts and challenges upfront, I think you can put controls in place to make reasonable tradeoffs. In the linux case, a precise and specific configuration control policy may have prohibited the problematic upgrade of one of the components that the 3rd party solutions required. This would have likely reduced the number of failures but would have put some hefty constraints on 3rd party solutions. To understand the implications for your environment you really need to run through the methodology with the assumptions and restrictions of your organization and I hope that this study either prompts or provokes people to do that.

2 - Meta-credibility?
by Tackhead
Where I come from (non-management, grunt-level techie), appearing in any of these analysts' journals *costs* an author more credibility than it gains him or her. For example, if $RAG says that $CORP has the best customer support, I immediately assume that $CORP has such horrid customer support that they had to pay someone to make up some research that proves otherwise.
To be sarcastic, I'd ask "who the heck actually takes these studies seriously?", but obviously *somebody* does. Who are these people, and why do these people take these industry analyst firms/journals/reports seriously? Are they right or wrong to do so? This isn't an attack (or endorsement :) of your research -- I'm talking about the credibility gap in industry research, and my observation that it's an industry-wide problem.
The meta-credibility question is this: Given the amount of shoddy pay-for-play research out there, does being published in an analyst journal tend to cost (a researcher, his consulting company, his financial backers) more credibility than it can gains him/her/them? If not, why not -- and more importantly, if so, is there any way to reverse the trend?
Dr. Thompson
This is a really interesting question because it cuts to the heart of what a real research study should provide to the reader. It should provide a baseline and I think research should always be questioned, scrutinized and debated because one can always find reasons for bias. Particularly, if a subject of the study (vendor for example) is behind its funding, whether directly (as in this study) or indirectly (meaning that they are big clients) I think it's critical that the study not provide just a baked cake for readers but the recipe as well. The recipe has to be inherently fair and simple, meaning that it has to map directly to a the quality or pain one is trying to measure without taking into account how the subjects try and provide that service or mitigate that pain. I think slanted opinion pieces, with no backup for those opinions, seriously hurts credibility, at least in my book. If you're presenting facts though and encouraging others to question them then I think that actually helps credibility, even if the search for those facts was paid for.
I agree though that one is tempted to dismiss research a priori though because of funding or some vendor tie. I think a good way to reverse the trend is to open the process up to public scrutiny; that's probably the main reason I came on Slashdot. To use this specific study as an example, some folks disagreed with several points in the experiment from counting patches, to reasons for upgrading key components, to the ecommerce scenario we used. For me, the study's key value is the methodology. Could different applications/scenarios have been chosen: absolutely!
The value I think that this study gives to the practitioner is arming them with a tool to help measure in their own environment. By applying the methodology, the results should take into account things like administrators skillsets, support policies, configuration control policies and the tradeoffs between customizability, maintainability, visibility, security and usability. It's only by looking at this stuff in context can one make a sound judgment; and a true research paper, especially one where funding is in question, needs to fully disclose the method and the funding source. In our case, the methodology has been vetted by industry analysts, IT organizations and several academics. That doesn't mean much, though, if you don't find the methodology meaningful for the questions you want answered. One reason I've come on Slashdot is to get the thoughts, opinions and assessments of the methodology itself from administrators in the trenches. I'm really pleased with the great questions and comments amidst the inevitable flames and I'm looking forward to this being posted so that others can weigh-in with their feedback and I can jump into the threads to get some discussion going.
If the research helps give real insight, and the methodology makes sense, I think there's real value no matter who paid the bill. At the end of the day, you need to decide whether or not you can extract any value from the information presented to you. In the case of this study, my hope is that it will leave you thinking hmmm.... maybe we should actually run through a process like this and check out how this works for ourselves. My more ambitious hope is that you'll implement it and tell me what challenges you faces on Windows, Linux, OSX, BSD, whatever platform you choose to compare. It may not even venture into the perennial Windows versus Linux battle; maybe you're a linux shop trying to decide between multiple distributions for example. Either way, if it's got people thinking about the topic and asking questions, well, that's all any researcher can really hope for.

3 - Weak setup
by 0xABADC0DA
If I understand the study correctly, the windows side had to do nothing but set up a server to do a few different tasks over time and run windows update. The linux side had to have multiple incompatible versions of their database server running simultaneously on a single system and had to run unsupported versions of software to do it.
Why wasn't the windows side required to run multiple versions of IIS or SQL server simultaneously? In real life if you need to run multiple database versions you use virtualization or multiple systems, especially if one requires untested software. You don't run some hokie unstable branch on the same system as everything else. Why was a linux solution picked that required this level of work? My other related question is, did any of the unix administrators question why there were being asked to do such a thing? For example, did they come back and say they need a license for vmware? If they did not they do not seem like very competent administrators in my opinion.
Dr. Thompson
The Windows Admins and Linux admins were given the exact same set of business requirements which doesn't necessarily translate into the same tasks as they went about fulfilling them. The 3rd party components installed were chosen solely based on their market leadership position and any upgrades of OS were unknown at the time of selection. That said, on the Windows side, it turned out that no upgrades of IIS were needed (except for patches) and SQL Server was upgraded to SP4 as part of patch application. On the Linux side, at a high-level there were two main classes of upgrades: MySQL and GLIBC and they were both prompted by the installed components. After the experiment, the administrators were asked on both sides if this kind of evolution of systems met with their real-world experience. They said yes, with the caveat of if they were asked to install a component that required an upgrade of GLIBC that they would likely upgrade the operating system as long as their configuration control policy allowed it.
You make a great point about installing components on some sort of staging system (which is almost always done) as opposed to live running systems. That still means that the problems that the administrators had equal real IT pain. If something weird had to be done to get the system running but it does run and it's then put into production it's like a fuse that gets set on a bomb. A careful configuration control policy would almost certainly help and thats why I think it's so important to conduct this kind of experiment in your own environment with your own policies.
As far as selection of the Linux administrators go, they all had at least 5 years of enterprise administration experience, and two years of experience on SuSE specifically. With three people there's certainly likely to be a lot of variability and to get some conclusive results, I'd love to get a huge group of administrators across the spectrum in terms of experience. I'd also love to do it across multiple scenarios, beyond the ecommerce study. For this experiment, basically the bottom line is that we Illustrate one clearly documented scenario with six highly qualified admins that we selected based on experience. We cant ensure equal competency levels, but there was nothing in our screening that would lead us to believe there were gaps in knowledge on either side. When it comes down to it though, the really meaningful results are the ones you get when you perform the evaluation in your environment. Hopefully this study provides a starting point for asking the right questions when you do that.

4- Who determined the metrics
by Infonaut
Did Microsoft come to you with a specific set of metrics, or did you work with them to develop the metrics, or did you determine them completely on your own?
Kudos to you for braving the inevitable flames to answer people's questions here on Slashdot.
Dr. Thompson
Great question! The metrics and the methodology were developed completely on our own and independent of Microsoft. They were created with the help and feedback of enterprise CIOs as well as industry analysts. I think that this relates to a couple of other questions on Slashdot with the gist of if Microsoft is funding the study aren't you incentivized for them to come out ahead. Besides the standard we would never do that and that would put our credibility at risk which is our primary commodity which are both very true, let me explain a little more about how our research engagements work.
Company X (in this case Microsoft) comes to us and says can you help us measure quality Y (in this case Reliability) to get some insight into how product Z stacks up. We say, sure, BUT we have complete creation and control of the methodology, it will be reviewed and vetted by the community (end users and independent analysts) and must strictly follow scientific principles. The response will either be: great, we want to know whats really going on or um, heres some things to focus on and I think you should set it up this way. In the first case we proceed, in the second case we inform that company that we don't do that kind of research. We are also not in the opinion business, so we present a methodology to follow and illustrate how that methodology is applied with the hope that people will take the methodology and apply it in their own environment.
All of our studies are written as if they will be released publicly BUT it is up to the sponsor if the study is publicly released. The vendor knows that they're taking a risk. They pay for the research either way but only have control over whether it is published, not over content. So if their intent is to use it as an outward facing piece, they may end up with something they don't like. Either way, I think it's of high value to them. If there are aspects of the results that favor the sponsor's product, in my experience, it goes to the marketing department and gets released publicly; if it favors the competitors product it goes off to the engineering folks as a tool to understand their product, their competitor's product, and the problem more clearly. Either way, we maintain complete editorial control over the study and there is no financial incentive for us if it becomes a public study or is used as an internal market analysis piece. The methodology has to be as objective as possible to be of any real value in either case.

5 - ATMs vs. Voting Machines
by digitaldc
How is it that Diebold can make ATM machines that will account for every last penny in a banking system, but they can't make secure electronic voting machines?
Also, does the flame-resistant suit come with its own matching tinfoil hat? (don't answer that one)
Dr. Thompson
This is a question that has passed through my mind more than once. The voting world is very interesting. I don't have experience with the inner workings of Diebolds ATM machines but I can say that the versions of their tabulation software that Ive seen have some major security challenges (see this Washington post documentary for some of the gory details). I'd say I'm concerned about the e-voting systems Ive seen but that would be a serious understatement.
I question whether the economic incentive is there for them to make their voting systems more secure. Take an ATM for example. Imagine the ATM has a flaw and if you do something to it, you can make it give you more money than is actually deducted from your account. Anything involving money gets audited and sometimes audited multiple times and chances are good that the bank is going to figure out that they're loosing money. On the flip side, if there was a flaw in the ATM in the banks favor, someone balancing their checkbook is going to notice a discrepancy. The point is that there's always traceability and there's always someone keeping score. If you think about voting tabulators though we've got this mysterious box that vote data gets fed into and then, in many states, only a fraction of these votes are audited. That means we don't really know what the bank balance is other than what the machine tells us it is. If the system is highly vulnerable and its vulnerability is known by the manufacturer *but* it's going to be expensive to fix it and shore up defenses, there seems to be no huge incentive to fix the problems. I think the only way to get some decent software that counts votes that people can have confidence in is to allow security experts to actually test the systems, highlight potential vulnerabilities, and put some proper checks and balances in place. That would give the general public some visibility into a critical infrastructure system that we usually aren't in the habit of questioning and will hold voting manufacturers directly accountable to voters.
As for the tin foil hat to go with the flame resistant suit; it hasn't been shipped to me yet - apparently the manufacturing company is still filling backorders from SCO :).

6 - Why are the requirements different?
by altoz
Looking at your research report's appendices, it seems that the requirements for Windows Administrators were somewhat different than the Linux Administrators. For instance, you ask for 4-5 years sys admin experience minimum for Windows, whereas it's 3-4 years sys admin experience minimum for Linux.
Why wasn't it equal for both? And doesn't this sort of slight Windows favoring undermine your credibility?
Dr. Thompson
Short answer: Typo. Long answer: We originally were looking for 4 years of general administration experience for both Linux and Windows which is what is reflected in the desired responses to the General Background questionnaire for Linux. We then raised it to 5 years for both Linux and Windows which is reflected in the General Background of the Windows questionnaire. The difference in the two was just a failure to update the response criteria on that shared section of one of the questionnaires. On page 5 though we've got the actual administrator experience laid out:
Each SuSE Linux administrator had at least 5 years experience administering Linux in an enterprise setting. We also required 2 years minimum experience administering SuSE Linux distributions and at least 1 year administering SuSE Linux Enterprise Server 8 and half a year administering SLES 9 (released in late 2004). Windows administrators all had at least 5 years experience administering Windows servers in an enterprise environment. These administrators also had at least 2 years experience administering Windows Server 2000 and at least 1 year administration experience with Windows Server 2003.

7 - Scalability of Results?
by hahiss
You tested six people on two different systems; how is that supposed to yield any substantial insight into the underlying OSes themselves?
[At best, your study seems to show that the GNU/Linux distribution you selected was not particularly good at this task. But why does that show that the ``monolithic" style of Windows is better per se than the ``modular" style of GNU/Linux distributions?]
Dr. Thompson
First, let's look at what we did. We followed a methodology for evaluating reliability with three Windows admins and three Linux admins. This is small sample set and it looked at one scenario: ecommerce. Is this enough to make sweeping claims about the reliability of Linux/Windows? No way. I do however think the results raise some interesting questions about the modularity vs. integration tradeoffs that come with operating systems. I don't think that either the Windows or Linux models are better in a general sense but they *are* different; the question is which is likely to cause less pain and provide more value for your particular business need in your specific environment. Hopefully these are the questions that people will ask after reading this study, and with any luck it will prompt others to carry out their own analysis within their own IT environment, building on what we started here. I think the methodology in this paper has provided a good starting point to help people answer those questions in context.

8 - Convenience vs. security
by Sheetrock
Lately, I've felt that Microsoft is emphasizing greater trust in their control over your system as a means of increasing your security. This is suggested by the difficulty of obtaining individual or bulk security patches from their website as opposed to simply loading Internet Explorer and using their Windows Update service, the encouragement in Service Pack 2 of allowing Automatic Update to run in the background, and the introduction of Genuine Advantage requiring the user to authenticate his system before obtaining critical updates such as DirectX.
In addition, Digital Rights Management or other copy protection schemes are becoming increasingly demanding and insidious, whether by uniquely identifying and reporting on user activity, intentionally restricting functionality, and even introducing new security issues (the most recent flap involves copy protection software on Sony CDs that not only hides content from the user but permits viruses to take advantage of this feature.)
I would like to know how you feel about the shift of control over the personal computer from the person to the software manufacturers -- is it right, and do we gain more than we're losing in privacy and security?
Dr. Thompson
This is an interesting problem because manufacturers have to deal with a wide range of users. If there was real visibility and education for users on the security implications of doing A, B or C then we'd be ok. It's scary though when that line gets crossed. Sony's DRM rootkit is a good example. But if you think about it, we are essentially passively accepting things like this all the time. Every time we install a new piece of software,especially something that reads untrusted data like a browser plugin,we tacitly accept that this software is likely to contain security flaws and can be an entryway into your system; NOW are you sure you want to install it? The visceral immediate reaction is no but then you balance tradeoffs of the features you get versus potential risks. Increasingly, were not even given that choice, and components that are intended to help us (or help the vendor) are installed with out our knowledge. This also brings up the question of visibility; how do we know what security state were really in with a system? Again, there are tradeoffs, some of this installed software may actually increase usability or maintainability but it's abstracting away what's happening on the metal. So far, it seems as though the market has tended towards the usability, maintainability, integration that favors bundling on both the Linux and Windows sides. It's kind of a disturbing trend though.
As another example, think about how much trustaverage programmers put into their compiler these days. Whenever I teach classes on computer security and then go off into x86 op codes or even assembly, it seems to be a totally foreign concept and skillset. We've created a culture of building applications rapidly in super high-level languages which does get the job done, but at the same time seems to have sacrificed knowledge of (or even the desire to know) what's happening on the metal. This places a heavy burden on platform developers, compiler writers and even IDE manufacturers because we are shifting the cloud of security responsibility over to them in big way. Under the right conditions it can be good because the average programmer knows little about security, but we need to make sure that the components we depend on and trust are written with security in mind, analyzed by folks that have a clue, and are tested and verified with security in mind. This means asking vendors the tough questions about their development processes and making sure they've got pretty good answers. Here's what I think is a good start. If that fails, theres always BSD. :).

9 - Apache versus IIS
by 00_NOP
Simple one: of course I accept that Windows and Linux are a priori equally vulnerable - C programmers make mistakes. The question is which model is most likely to deliver a fix fastest. Given that the one area where Linux is probably in the lead over Microsoft's software is in the realm of the webserver - why are my server logs filled with artifacts of hacked IIS boxes but apache seems to remain pretty safe?
Dr. Thompson
You bring up a couple of interesting points. The first is patch delivery. It's true that on Linux if there's a high profile vulnerability you're likely to be able to find a patch out on the net from somebody in a few hours. Sometimes the fix is simple, a one-liner, and other times it may be more complex. Either way, there could be unintended side effects of the patch which is why there's usually a significant lag between these first responder patches and a blessed patch released from the distribution vendor. Most enterprises I know wait for the distribution patch as a matter of policy, and even then, they go through a fairly rigorous testing and compatibility verification process before the patch gets deployed widely. In the Windows world, one doesn't get the alpha or beta patches, just the blessed finished product. So the question is which solution is likely to provide a patch that fixes the problem and doesn't create any more problems the fastest. That's a tough one to answer. I think theres something to be learned by looking historically and that in general theres a big discrepancy between perception and reality. Here's a (pdf) link to a study we did earlier this year based on 2004 data that I think provides a good starting point for answering that question.
As far as why you've got so many attempts on your Windows/IIS box, I think there are two distinct issues: vulnerability and threat profile. In the past, I would argue that the path of least resistance was through Windows because desktop systems were often left unprotected by the home computer user. Bang-for-the-packet favored creating tools that exploited these problems and some of the attacks actually worked on poorly configured servers as well. Then there's the targeted vs. broad attacks. Theres no question that the high-profile worms and viruses in the last several years have favored Windows as a target. The issue gets even more complicated when you look at targeted attacks. These targeted attacks are much harder to measure, even anecdotally, because either an organization gets compromised and doesn't disclose it (unless they're compelled to by law) or the attack goes undetected because it doesn't leave any of the standard footprints, in which case no pain is felt immediately. That may help to explain it but the truth is that there's a lot of conflicting data out there. I remember reading this on Slashdot last year which claims Apache was more attacked than IIS but I've also read reports to the contrary. The reality is that any target of value is going to get attacked frequently. If there is an indiscriminant mass attack like a worm or virus, that's pretty bad and can be really painful. What's scarier though is the attack that just targets you.

10 - Do you agree with Windows Local Workflow
by MosesJones
Microsoft and Linux distros have had a policy for some time of including more and more functionality in the base operating system, the latest example is the inclusion of "Local Workflow" in Windows Vista.
As a security expert do you think that bundling more and more increases or decreases the risks, and should both Windows and Linux distros be doing more to create reduced platforms that just act as good operating systems?
Dr. Thompson
Three years ago I bought my mother a combination TV, VCR and DVD player. It was great; she didn't have to worry about cables or the notorious multi-remote control problem. She didn't even really need the VCR because she hardly ever watches Video tapes, but I thought, why not. It worked great for two years, mom watched her DVDs, and on a blue moon a video tape from a family vacation would find its way into the VCR. All was well at the Thompson household. This past year, tragedy struck. The VCR devoured a videotape, completely entangling it in the machine. This not only knocked out the VCR but the television too (it thought it was constantly at the end of a tape and needing to rewind it). So here's the issue: mom probably only needed a TV and a separate DVD player. I probably could have gotten better quality components individually too, and with some ebay-savvy shopping, the group may have been cheaper. For my mom though, the integration and ease of operation of the three were key assets. The flipside of that is that the whole is only as strong as the weakest of its constituent parts, and by the manufacturer throwing some questionable VCR components into the mix, it caused the whole thing to fail. The meta-question: did I make the right choice, going for the kitchen-sink approach versus individual components? I think for mom I made the right call. For me, my willingness to program a universal remote and my love of tweaking the system would have lead me down a different route.
In operating systems, it depends what you're looking for and what the risk vs. reward equation is for you, and I would argue that the answer varies from user to user. The ideal would be something that gave you integration, ease of use, visibility, manageability and the ability to truly customize and minimize functionality and maintenance requirements. No operating system I've ever seen strikes that balance optimally and for every user. As far as bundling functionality with the distribution, I think it's a question of market demand. There's no question though that from a simple mathematical perspective, the less code processing untrusted data the better. That means if I need a system to perform one specific function, and that function was constant over time, then from a security perspective I only want the stuff on that box that does what I need to serve that goal. For example, I don't ever want X Windows on my linux file server. I just want the minimal code base there because as long as the code itself is reliable, I'll only have to mess with the box to apply patches (and much fewer patches if I strip the system down). That's true of my home fileserver. If I have an army of systems to manage though, my decision is going to come down to which platform is reliable and extends me the most tools to manage it efficiently and effectively. That's a question that can only be answered in context. I can tell you what I run at home though. File server: Red Hat EL 4 (no X windows). Laptop: Windows XP SP2. Desktop: Windows Server 2003 with virtual machines of everything under the sun from Win 9x to SuSE, Red Hat and Debian. -
California Class Action Suit Sony Over Rootkit DRM
carre4 writes "Lawyers in California have filed a class-action lawsuit against Sony and a second one may be filed today in New York. The lawsuit was filed Nov. 1 in Superior Court for the County of Los Angeles by Vernon, CA attorney Alan Himmelfarb. It asks the court to prevent Sony from selling additional CDs protected by the anti-piracy software, and seeks monetary damages for California consumers who purchased them. The suit alleges that Sony's software violates at least three California statutes, including the "Consumer Legal Remedies Act," which governs unfair and/or deceptive trade acts; and the "Consumer Protection against Computer Spyware Act," which prohibits -- among other things -- software that takes control over the user's computer or misrepresents the user's ability or right to uninstall the program. The suit also alleges that Sony's actions violate the California Unfair Competition law, which allows public prosecutors and private citizens to file lawsuits to protect businesses and consumers from unfair business practices. EFF has released a list of rootkit affected CD's and Slashdot user xtracto also has a list." -
Slashback: OpenDocument, Intelligent Design, More DRM
Slashback tonight brings a few corrections, clarifications and updates to previous Slashdot stories, including several updates to the Sony DRM rootkit fiasco, another school system's take on intelligent design, some of the first pictures of the much talked about avian flu virus, a sentencing that gives us the first torrent user to get jail time, Bernard Golden weighs in on the continuing Massachussetts OpenDocument debate, and one users commentary on recent announcements to start pay-per-download services for TV shows. Read on for the details.Sony still not "getting it". c writes "Mark Russinovich continues his investigation of Sony's DRM as he tries out the official uninstaller. His verdict? 'I've analyzed virulent forms of spyware/adware that provide more straightforward means of uninstall.'" Relatedly Cronos1388 writes "According to the Inquirer an Italian group is also suing Sony over the rootkit." Also, an unexpected side effect of this technology is that script kiddies have been able to leverage Sony's tool to hide unauthorized cheat programs from the watchful eye of MMO creators.

User says new downloadable television just plain "sucks." Thomas Hawk writes "In the past few weeks the three major studios have all announced deals to begin offering downloadable television for consumers -- Apple/ABC, DirecTV/NBC, and Comcast/CBS. The problem with each of these respective offerings is that they largely suck. Apple sells expensive low res limited television from ABC. NBC's new service will only work on DirecTV DVRs (uh hello McFly, why pay money for this service when I can just record it for free). And CBS' downloadable programming could contain commercials."

Sony Rootkit Phones Home
strider44 writes "Mark from Sysinternals has digged a little deeper into the Sony DRM and discovered it Phones Home with an ID for the CD being listened to. XCP Support claims that "The player has a standard rotating banner that connects the user to additional content (e.g. provides a link to the artist web site). The player simply looks online to see if another banner is available for rotation. The communication is one-way in that a banner is simply retrieved from the server if available. No information is ever fed back or collected about the consumer or their activities." Also on this topic, Matt Nikki in the comments section discovered that the DRM can be bypassed simply by renaming your favourite ripping program with "$sys$" at the start of the filename and ripping the CD using this file, which is now undetectable even by the Sony DRM. You can use the Sony rootkit itself to bypass their own DRM!" Update: 11/07 14:21 GMT by H : Attentive reader Matteo G.P.

How Do I Determine If My PC is a Zombie?
Captain Chad wonders: "With the recent news of a 1.5-million node botnet, as well as the AIM rootkit worm, I'm getting a bit concerned about whether my PC may be a zombie. I'm seeing a lot of internet activity, even when nothing is running, and I've checked the process explorer for obvious tasks to no avail. I apply patches as soon as they're released, and my antivirus/spyware programs report nothing. How do I determine if my PC is a zombie, and if it is, how would I de-infect it?" On this same vein, college campuses are often prime breeding grounds for undead-boxen. bcrowell adds: "I'm a teacher at a community college where Windows is the only supported OS -- if you ask the school to put machine on your desk, you get a Windows box. Faculty who want to run MacOS or Linux have had to provide their own machines, and those who want to do PowerPoint presentations for their classes have been told that they have to buy their own laptops and bring them in.
Now Academic Computing has announced a new policy: any unauthorized use of the network, such as plugging in your own computer to a port, is prohibited, and will result in disciplinary action. There are supposedly plans to enforce this rule automatically with hardware and software. Great consternation has ensued in the faculty senate, and the manager who wrote the policy has explained that it is basically aimed at the problem of improperly maintained teachers' machines getting '0wned'. A little ironic, because the Windows boxes maintained by the computing folks keep getting infected by worms. Still, it's not an unreasonable concern; many teachers are clueless. In fact, I wouldn't pretend to know enough to keep a Windows machine secure on a public network, although I haven't had any problem with the FreeBSD box on my desk. Any suggestions on how to deal with this? Effective arguments to use? Good educational resources to point people to so they can learn how to keep their Windows boxes secure? Many of my colleagues seem to think that security mainly involves buying antivirus software." -
Sony DRM Installs a Rootkit?
An anonymous read writes "SysInternals.com guru Mark Russinovich has a detailed investigation of a rootkit from Sony Music. It's installed with a DRM-encumbered music CD, Van Zant's "Get Right with the Man". (Mmmm, delicious irony!) The rootkit introduces several security holes into the system that could be exploited by others, such as hiding any executable file that starts with '$sys$'. Russinovich also identifies several programming bugs in the method it uses to hook system calls, and chronicles the painful steps he had to take to 'exorcise the daemon' from his system." This house is clear. -
Running Windows With No Services
mattOzan writes "So how many of the almost 4 dozen default-enabled services does Windows XP really need in order to preserve basic functioning, like web surfing and running applications? Zero, as it turns out. Mark Russinovich at Sysinternals demonstrates that if certain steps are followed, Windows XP will still run with only two active processes: System and Csrss.exe. No Smss.exe, Winlogon.exe, Services.exe, Lsass.exe... And, contrary to the expectations of various lead engineers at Microsoft, even Internet Explorer will still work under such conditions." -
SysInternals Releases RootkitRevealer
Brian writes "In the wake of news that Microsoft is developing prototype software to detect rootkits, SysInternals has released a free rootkit detection tool named RootkitRevealer for all Windows systems NT4+. RootkitRevealer works by "comparing the results of a system scan at the highest level with that at the lowest level," and detects every known rootkit at rootkit.com. They also report that it is impossible to know for sure that a given system is clean from within it, but that defeating their tool would require a level of sophistication not yet seen. You can download RootkitRevealer." -

Windows Forensics and Incident Recovery
dba599 (Mark McKinnon) submits this review of Harlan Carvey's Windows Forensics and Incident Recovery, writing "This book takes an unusual approach to computer forensics in that it deals only with live analysis of the system: the compromised computer is left powered on and everything is running. (Compare to a dead analysis, for which the computer is powered off and the hard drive's contents are then analyzed.)" Read on for the rest of McKinnon's review. Windows Forensics and Incident Recovery author Harlan Carvey pages 460 publisher Addison Wesley rating 9 reviewer Mark McKinnon ISBN 0321200985 summary Forensic analysis and incident recovery on a live Microsoft Windows is explained for the system administrator, security administrator and knowledgeable home user.The intended audience, according to the author, is "anyone with an interest in Windows security, which includes Windows system and security administrators, consultants, incident response team members, students and even home users." The author assumes the reader is familiar with basic networking (including TCP/IP) and has some Windows administration skills. Some programming ability, though not actually required, will help out greatly with reading and understanding the many examples provided, and will let you make your own modifications (this is encouraged by the author throughout the book).
The chapter on data hiding was a real eye-opener -- it's amazing the things Microsoft has implemented as part of the operating system (and included applications) that can be used to hide things. Discovering the hidden information is talked about, as well how it is hidden. Sample topics include file attributes, alternate data streams, OLE and stenography. This is an excellent chapter with many examples; I found myself stopping after each subject to try out each of the discussed techniques.
The next chapter delves into incident preparation. Carvey addresses some of the things that administrators can do to harden their systems. He goes over the application of security policies in general, as well as intelligent assignment of file permissions. He then covers Windows File Protection and how it is implemented, and includes a perl script to implement your own file watcher. He touches briefly on patch management and anti-virus programs, then moves into monitoring. He provides quite a few scripts, and discusses other means by which you can monitor your system.
The next chapter describes tools that can be used in incident response. This chapter has quite a lot of information and took me the longest to get through, because of all the tools mentioned that I had to download and check while I was reading the book. Carvey uses a mixture of his own perl scripts and programs that can be downloaded from places like Sysinternals, Foundstone, DiamondCS and others. All of the tools used are open source (or are at least freely available). That equips the reader with a low-cost toolkit, especially important to the home user or small business owner who cannot afford to buy the commercial equivalent. Carvey does acknowledge, though, that there are quite a few commercial tools with great functionality out there.
The first part of the incident-response tools chapter deals with the collection of volatile information (processes, services, etc.); this is a vital part of live analysis. The second part deals with the collection of non-volatile information (the content of the Windows registry, file MAC times and hashes, etc.) and tools for analyzing files. Carvey also shows how some of the tools complement each other, and that there is not one almighty tool that will find all the data you need. (This is also proven by example in a later chapter when he talks about rootkits.)
The next chapter deals with developing a security methodology, and it's handled differently than in most books: the author presents the material as a series of dreams that a Windows system administrator has, showing how an individual can come up with and fine tune a methodology as incidents happen. Carvey has used this approach before in a series of articles entitled "No Stone Unturned" for SecurityFocus.com, and the creative approach appeals to me. As he moves from dream to dream, you can relate to the admin's circumstances (and mistakes), and how be and becomes better at responding to different incidents.
The next chapter talks about what to usefully look for with the tools the book has introduced. It discusses infection vectors, types of malware and rootkits, and demonstrates tools and techniques for detecting them. This is where the author makes a clear point of why you would need to run several different tools, even if some overlap. His example uses an installed rootkit; running a particular program from a previous chapter, he shows that it fails to find that anything untoward is running -- it takes another program from the same chapter to actually reveal the rootkit's presence. By cross referencing the output for both programs, you can see why you should run more then one type of analysis tool for certain areas to make sure you are not missing anything.
Finally, the author dedicates an entire chapter to his own Forensic Server Project, a two-pronged approach to live forensic analysis which uses two machines simultaneously. The first piece, the Forensic Server Module, is the listener software; this runs on a clean PC where the data will be sent from the compromised system. The other piece, called the First Responder Utility, runs several of the programs and scripts from the incident tools chapter on the compromised system . After installing everything needed for both parts of this system, I followed the author's instructions on how to run it. What a slick tool! I ran it from a couple of PCs on my home network and was able to get a lot of the information that was described in the book as well as hash values for each log file that was produced, and a general log of everything the First Responder Unit did. The whole principle of this is that when you have an incident there will be very little interaction with the compromised system, since everything is scripted to begin with.
The framework that this software constitutes is very flexible. I was able to add two new features to the Forensic Server Module and the First Responder Utility with very little code. The first addition I made was to mark all the logs as read-only on the file system after they were written from the Forensic Server module. The next addition I made was to add a perl script to scan the c:\ drive of the PC that the First Responder Utility was running on. After I made both additions, I tested everything out, and it worked great. I had my extra log files and they were all read-only. My hat goes off to the author for coming up with and including this in the book, a really nice piece of software.
