Target's Data Breach Started With an HVAC Account
Jim Hall writes "Security blogger Krebs reports that Target's data breach started with a stolen HVAC account. Last week, Target said the initial intrusion into its systems was traced back to network credentials that were stolen from a third party vendor. Sources now claim that the vendor in question was a refrigeration, heating and air conditioning subcontractor that has worked at a number of locations at Target and other top retailers. Attackers stole network credentials from Fazio Mechanical Services, then used that to gain access to Target's network. It's not immediately clear why Target would have given an HVAC company external network access, or why that access would not be cordoned off from Target's payment system network."

Please mod down in advance, thanks.
Well, the beta sucks, but to the article's point, Target wasn't following PCI guidelines.
That's the problem right there.
Dear DICE:
We're not "your audience", we're your CONTRIBUTERS. You're just the chalkboard we have our discussions on. Shut the fuck up, display a few ads, and stay the fuck out of the way.

If Beta was hot grits, then Natalie Portman would be driving Beowulf cluster of HUGOs!
why Target would have given an HVAC company external network access, or why that access would not be cordoned off from Target's payment system network
Because they have just one big unified network for everything. That probably saves them money, unless something really bad were to happen...

Maybe this is why we have the slashdot beta issue, something came in with the HVAC account at dice. It sucks enough that the HVAC system might be to blame.

The design of their security. They should redesign it by committe. Here are some suggestions for your Target Security Beta:
* More whitespace. Credit card thieves hate whitespace.
* Big goofy graphic before they can steal your credit card info
* Force a lot of scrolling, this will definitely send attackers away
* Make the store look like Buzzfeed. This will send them screaming.
Under [pure] Bitcoin, only the owner of money can initiate a transaction.
Might as well give HVAC vendors access to the slashdot beta servers so they can destroy it as well.

BETA must have started with an HVAC account as well; that's why it sucks so badly.
In case Slasdot forks...I suggest if someone wants to register with user name that exists on slashdot, ask him to post a slashdot comment containing a particular key, and then give that comments's link. This way, we will know that Anne_Nonymous is Anne_Nonymous etc.
With the beta you can only see 3 or 4 whiny replies per page on a big screen.
No way I'm scrolling through thousands of them.
I don't think I could be arsed to read through many good ones either.
Buh Bye
P.S. It automatically ate my line breaks. Funny it wants to save space by removing actual message formatting.
It might be "easier" to run a unified network but that doesn't explain why they ignored PCI laws.
It's good thing to remember as they take you (the target CTO) off to prison.

They probably have it all on one network so they can easily correlate the data. HVAC settings will influence purchases and a smart store is dynamically setting temperature to maximize sales volume, although within certain constraints.
This "protest" is generating quite a few page views.

After seeing what the new beta site looks like, in the future "being slashdot'd" will mean being destroyed by someone who does not understand what they are destroying.
Beta sucks
FUCK BETA
Did the software have fixed passwords / users?
Some software needs an fixed login to work.
Target fucked somewhere between 40 million and 110 million people. DICE is now trying to fuck something south of half a million people.
Cut this shit out. Revert. Take the DICE Marketing department out for a nice big lunch, drinks and all. Then send them home for the weekend. Then undo the damage they've done.
I'm sadly sure that this is an intentional ploy to drive away long-time users ("geeks" and "nerds") who have contributed so much that, like me, they're eligible to disable advertising. What they don't understand is that even if my karma was shit (we don't get numbers anymore, I guess mine would be 50++++++), I'd still be using Ghostery and AdBlock to block the ads without Slashdot's generous option.
Wake up, guys. This is a tech site. The comments make the site. The users make the site. We aren't going to sit around and watch it go to shit. You will have nothing, ZERO left if the beta interface goes into production, except for a few new users who came over from MSNBC.
Writing, wall, see it, hope you have negotiated a nice severance package.
Thanks to the War on Drugs, it's easier to buy meth than it is to buy cold medicine!
I have gone through this exact same "logic" at places where I've worked. It's impossible to explain to some people that ... while the person putting in X may be completely honest you are depending upon that person to have as good security practices as you have.
Except that that person does not have any idea of what network security is. Or computer security.
But it will make it easier if vendors X, Y and Z have remote access to their systems which are on the production network.
It will be more difficult if we have to pay an ISP for the cheapest line they have and colour-code it and label it and super-glue it so that they have access but it does not touch the production network. At least not without someone coming in and physically re-wiring it.
Yes, that is right, the Beta UI of Slashdot is the best invention ever. I am sure that the HVAC system could also benefit from it. Who wouldn't want a system that looks like 'any other site', feels un-nerd-like and is guaranteed to drive away advanced users ! In the end, the system is sure to draw the attention of only those people that want to spend time spamming and trolling. I think it is a great idea for that purpose...
That, and Beta sucks.

I cannot comment on this story because I can only display 2 comments at a time on the screen - despite there being loads of unused real estate down either side of the page. I'll spend the rest of the evening srolling down to see if I can work out who is saying what....
Just called the owner of Slashdot on 212-725-6550, even his secretary knows already the subject in advance.
The redesign of Slashdot, I think they got the message, but maybe you have to make sure...
Because good security, like anything else worth buying, costs $$$. So it looks like a loss on the books. Remember, "the books" don't show the loss Target's taking in lost trade until the trade is lost by incidents like this. And even then, I'll be they don't do very much other than put some cosmetics on their system.
For the same $tupid reason: "The $tockholder$ won't like it."
Either A) some IM, email, or trouble ticket system, or B) remote setting of network enabled thermostats and diagnostics of HVAC units remotely. And the submitter can't think of that? Then why post it. And why not segregate the payment system? Uh, cause that costs money to do, and PCIDSS is a fucking stupid thing 99% of the time. It is only used to blame retailers instead of making the Vendors and Card companies design and ensure airtight security, as it should be. Does make one wonder why any retailer POS system should travel on the Intertubes and networkable systems, though, instead of fixed landline. (Yeah, unrealistic, but if the credit card industry won't man up and take responsibility then maybe that's what they should be relegated to.)
I honestly don't understand what the fuss is about.
Because the /. beta can't even properly suck on my nuts :(

Dice can't see it, since they are new here (he he)...
The most loyal long time most avid readers of Slashdot, are not trolling the site, in protest of the failed beta. Never thought I would see the day ...
Where is GNAA, Natalie Portman grits, and frist prost when you need them!
Let me explain ...
I have been a regular visitor to Slashdot for around 15 years. For that, I get the checkbox to disable ads, though I browse with Javascript disabled so my browser does not slow down.
I come here for the discussions, and often read comments at +5, changing that only if I find a discussion interesting and warrants reading at a lower level.
The new beta uses JQuery for the comment threshold selector, and changes that on the fly. This means all the comments are loaded, but not visible, and processing any page with considerable number of comments will slow down MY computer! If I have a few tabs open to read later, my computer will be unusable.
What is worse it that they require you to click on the slider on every article to change the threshold! This is just insane!
If they insist that I enable Javascript to browse the site at the threshold I want, then they will lose me as a long time. I imagine that others long timers will hate the site too.
Dice have to remember that this site has two unmatched features, interlocked: a moderation system that is good at cutting down the trolling, spamming, and noise, and a comment section that is frequented by many people who are passionate about technology and other nerdy stuff.
If they wanted to intentionally ruin the site and drive people away, they would not have done any worse than what they are doing now.
If they manage to aggravate a lot of their users, the comment section will no longer be attractive to the audience. Perhaps we should revive kuro5hin?
I wrote the above in a feedback form that I filled a while ago, and I am emailing this comment to their feedback@slashdot.org. Please send them feedback too.

Depending on your point of view, two things that suck, or blow...
It's not immediately clear why Target would have given an HVAC company external network access, or why that access would not be cordoned off from Target's payment system network.
Not clear if these conglomerate retailers are part of the bankster push for international electronic monetary data systems: ie, the microchip implants are coming.
I've woken up hung-over and found women in my bed that looked better than BETA. I've never regretted fucking them as much as I'd regret FUCKing BETA!
I pretty much left slashdot once, when Dice took over, because the quality of the content went downhill... now the quality of the site has gone downhill too. So long slashdot. BTW, for those who remember CmdrTaco, he's working on a pretty interesting new project called Trove - check it out!
I have been lurking around here pretty much since Slashdot's inception. I finally felt the need to make an account today to let it be known that I will be joining the Slashdot boycott on February 10-17th. I (and apparently everyone else) made their feedback for the beta when it was introduced. They decided to not listen. This site is truly something special, its community and insightful discussions are completely unmatched. We can't let them ruin it. Join the boycott, a severe drop in traffic should get their attention because apparently our protest is falling upon deaf ears.
NO BETA - Save our community. Boycott Slashdot Feb. 10-17th
common user / pass are easier to work with and manage when you are dealing with contracts / subs even more so in an area like hvac where the workers are not IT people and you have field work that can get subbed out to local firms now giving each tech there own login can be hard to keep track of and you have to deal with lock outs do to expiring passwords as they may need to use them day to day.
Is there an obligatory XKCD to explain how badly Beta sucks???
PCI is a compliance issue, not law. The payment card industry will just make you pay more for your credit card transactions if you're not compliant.
PCI also widely open to interpretation so it isn't exactly a standard. I worked for a company that implemented PCI on it's own product. We always had PCI "auditors" or "experts" who claimed we were not compliant. Once we made them read the document, they shut up. Who knows who Target hired for PCI compliance? You can have unencrypted credit card go over https and that's compliant. You can have it behind a firewall and that's, you guessed it, compliant.
The real problem is that PCI puts the onus on retailer to make cards safe when it's up to the payment card industry to make their cards and transactions more secure. It's a B.S. standard that only places a band-aid on the real problem.
Post this on every story that pops up, even if it's already been posted. IRC for slashdot refugees. http://webchat.freenode.net/?c...
It's not immediately clear why Target would have given an HVAC company external network access,..
They probably have access to the network because the heating and AC for the stores is centrally controlled, like it is at Walmart, for instance. That's not a suprise. ... or why that access would not be cordoned off from Target's payment system network."
This is definitely the bigger question. PCI is pretty clear about this. My next question is, how did they pass the audit?

Just trying out this BETA product. Looking good! :=)
But then Beta was switched on and I quickly turned away. :(
I was thinking something similar, but it was more like being destroyed by the very community that you were trying to court... out of an unwillingness to heed the warnings from that same community.
Getting tired of Slashdot... moving to Usenet comp.misc for a while.
Then why minimize (literally) the community's contribution? This box I'm typing in is given less than 1/4 of the page width here. The rest of that space is off-center column lines and unused space. Everyone's comment below mine will get even less space. If you value discussion and "contribution," then allow that content to shine and give it the visual weight it deserves. Also: Where are my line breaks? This is Usability 101 stuff here, guys...
One of my accounts has remote web accessible thermostats and the site share's a single public static IP, but my intranet is split between 3 different lan segments with the POS segment isolated. Looks like it might be NSA preferred level of effective security configuration...
seriously - wtf. I was getting annoyed by all the anti beta protestors - until I was forced to view beta. fuck beta, I come here to read threads of collapsed discussion not this 5000 pages of bullshit.
I get that Target might've forced their IT department to take the cheap way out and forgo a nice, isolated building management system. That's out of their control.
But how could they not notice the spike in network traffic as data was being sent to the hackers?
They should know how much bandwidth their terminals are chewing up on average, how many transactions are occurring, approximately how much data should be crossing the network per transaction and have an eye out for a sudden burst of outgoing data heading to one IP address.
Is there something I'm missing here?
I'm on Beta now, and while it's too much into "white space" and definitely far less practical, I don't see why all current discussions have to be spammed with complaints. At present I don't want to read /. in any form.
Dice: Frankly, many of us want a new design, Classic is broken in so many ways. But beta is terrible, and this is what is wrong:
* The value that Slashdot brings to its users is not in its articles. Frankly, the articles are terrible. The value that Slashdot provides is a discussion forum for self-selected nerds.
* As such, it is vital that you remember that the community is not just an audience, it is also your primary content creator.
* Your new redesign does not allow the community to create (or even consume) content because:
- It makes it impossible to follow discussions in the comments sections. This is largely because of the max-width on window and the fact that of the space left over is taken up by a useless sidebar. The vertical spacing is also overdone.
- Slashdot has a fragile but effective moderation system. Your changes make it impossible for readers to leverage that system to read a high quality discussion and ignore the trolls.
- It disregards conventions of the community. UIDs matter. We’re nerds. We understand that you need to attract a younger audience, but for a lot of us (including the younguns) it is thrilling to see a post from somebody who has been there from the beginning.
* In the last 24 hours Soulskill has bitterly commented that the community has been involved since October and that they also get emails supporting the new design; only the comments are an echo chamber. This comment demonstrates a deep incompetence in your development team. Soulskill should have been citing A-B testing numbers. A-B testing is cheap, easy and effective but instead you are taking stabs in the dark.
* Your ability to attain user acceptance is dismal. A number of years ago, when Taco needed to modernize the site, he solicited the community for designs, and awarded the best designer and used that design. That is how you leverage a community and gain their acceptance: incorporate them in the design process. As a bonus, you won’t have utterly useless redesigns that will either ruin your website or have to be scrapped.

The stores aren't heated. They're FREEZING!
Apply your silly argument to electrical wiring and you'll see exactly how silly it is.
Considering the likely consequences it's worth treating this stuff almost as seriously as electrical gear. You should NEVER have building facilities staff routinely making changes without informing the IT department in such an environment. The consequences of failure are too great and a part time cable monkey is so cheap. It doesn't take long at all to turn a member of building facilities staff into someone that will know what they are doing and will inform IT when changes are made.
There is already something like that, here.
But it deals with the CSS only, and will not handle the backend part. See my comments on the above comment.

"Slashdotted"? Should be "Diced" instead.
i prefer really wide comments section(like before) as i have a side by side dual monitor layout, and prefer indentation in the threads over box-within-box. I have set my display to be at arm's length, like when i might need to tilt the flatscreen. The boxes' lines can be annoying instead of helping, but if you must use them,at least alternate them, something like black lines-dark-lines-gray lines, and so on.

Big box retailers that have say 1000 or more stores realize that they can save significant amounts of money by controlling HVAC and lighting. None of that is controlled at the store - there might be an override that a manager can use - but it's one of those THINGS that is purposely a PITA to make them not want to do it...
Temperature, humidity, ventilation, light levels - all controlled by a schedule tied to how the store is used. There's one level for overnight stocking/cleaning, and another for customer times... Occasionally, the store is open earlier for a sale and the local or regional schedule has to be accommodated. The PLC's that control all this stuff need to be programmed accordingly, so rather than paying a fully-loaded Big Box employee, they pay a consultant, who pays a gnome to handle it.
They remote in, upload the schedule, or push out an immediate change (like Jimmy the Overnight guy had a heart attack, turn all the lights on for the ambulance!) and it's all good.
The problem is that they rarely restrict those logins once they're logged into the network... Or there's some common hole to get around... A big box retailer I worked at had a Unix-based system... vi was the editor. Anyone remember :! sh ?? Dropped you to a shell, and ummm, the whole thing was running as root, so need I say more?
Everyone seems to be assuming that because the hack *started* with the HVAC account, that it was done *only* using said HVAC account.
The first step in such an attack is to get access to the network. The access level doesn't have to *start* with your ultimate goal, you just need to get your foot in the door. From there, you take advantage of network/OS/software security flaws, social engineering, etc. to gain the access privileges you ultimately need.
Here's what I want to know. Did the NSA have knowledge about this vulnerability? If they did, and they didn't report it, they should be held at least partly accountable. Based on what we've learned that the NSA knows, it's likely they both knew about these vulnerabilities and knew that Target was vulnerable to them. Target should launch a FOIA request to find that out, and then sue the NSA for failing to disclose these vulnerabilities.
i build targets...infact i do the cabling side of it and i can tell you it is nessisary for the HVAC companies to have external access to networks, and they do have separate VLANS to try to avoid these kinda of things but i think the hacker prolly just knew what he was doing....duh they were a hacker lol
Beware the InsaneClown!!
It is where they started. Do they do online purchases? Do they do cash register purchases? So there is somewhere where store centric networks and corporate networks converge, probably an accounting system
So some store had remote access for climate controls, and also had the store network attached to the hvac controls so the manager could turn up the heat. HVAC credentials dropped a sniffer, found a user device coming in, jumped on there, back to the rest of the network.
Some idiot didn't just trip over the keys to 70 million records. Someone didn't decide to do this the day before Thanksgiving for BlackFriday. It was a very long process that didn't get noticed until the real hackers gave some script kiddies the keys to muddy the waters.
Our Building Automation (HVAC, Lighting, ect) system does not need VPN to work.

My Point: Where major consequences are possible care should be taken.
The electrical wiring bit was an analogy of something else with major consequences so there's no point shifting the goalposts to low voltage (WTF?) especially since that doesn't apply to building wiring anyway apart from in a few rare edge cases.
The issue is simple. An outsider needs limited access. You can do that without complex ACLs on everything.
Outside of computing it's managed pretty damn well with door keys that give differing amounts of access so why should we think we are special just because we work with computer networks?
