Linux saves Aussie electrical grid

Open sauce to the rescue
Thursday, 1 October 2009, 09:52

QUICK THINKING open sourcerers might have saved an Australian power supply system after its electrical grid control room network got infected with a virus.

A Windows virus hit the networks of Integral Energy and, according to a submission to Slashdot, the virus managed to spread to the operator display consoles in the control room.

Quick thinking techies in the control systems department of the utility swapped the infected Windows boxes for machines running Linux that they were using for development.

The move prevented the virus from taking over all the operator displays in the control room.

There have been a number of government inquiries into the security of electricity companies worldwide because of the fear that hackers, terrorists or cyber warriors for a rival country might take control of electric power grids. Now it would seem that such fears might have been realised.

However in Oz there could be some concern that notoriously insecure Windows machines were even being used for critical infrastructure systems. The Slashdot submission says that the power grid's system control and data acquisition (SCADA) servers run Solaris Unix and the operator consoles only really need to run X-windows displays. The question is why the utility would choose to run X on Windows boxes merely to talk to the UNIX-based SCADA servers that control the electrical grid.

According to the Sydney Morning Herald, so many other Windows machines at Integral Energy were found to have been infected by the virus that more than 1,000 of them have had to be rebuilt.

A spokesman said that the malware had not affected power supplies to customers or business data and was "contained within Integral Energy's information technology network".

However insecurity consultants who have looked at the Integral Energy network said that there was often "ineffective segregation" or "more typically none at all" between the the company's general use IT network and its supposedly separate, secure network that monitors and controls the electrical power infrastructure.

The virus was the W32.Virut.CF strain, which computer security company Symantec describes on its website as "a particularly sinister file infector".

Oddly the signature to detect this virus has been around on virus checkers since February and so it should have been spotted. It has been speculated that Integral Energy might not have upgraded all of its security software since January or earlier. µ

Get Real

So it was really Solaris trusted to run the critical systems, not linux, and therefore Solaris which really saved the system from a major failure.

Pay attention, the servers were running solaris, but infected Windoze machine were replaced by Linux boxes.

Linux doesn't fix the problem

Security by obscurity isn't the means to end all security problems.

Obviously the security infrastructure has failed at this company. Time to pull their regulatory licenses. Shut them down, their running is a bigger threat than them not running. It is far better to rely on something not being there, than it is to rely on something built like a straw house.

Security by obscurity is MS FUD.
There are much more sensitive information and money on Linux servers of Wall Street then in millions of Windows PC's. In general there are much more value for hacker in few Linux servers then in all useless Windows porn collectors :)
Other example is Mac. Market share grown, number of viruses close to 0.
The fact is that it is much easier to hack Windows to get access to Linux servers.
Bank accounts is good example.

How about MacOS?

Well they could get rid of the infection with any other unpopular system still not targeted by hackers, like that one from Apple which is nothing more than a heavily bloated FreeBSD which turned out to be not free at all.

However, I suppose it would fiercely suck up so much electricity from this very grid that they would rather deal with a virus which is only a temporary problem.

If they can't secure a Windows box, then there's not a snowballs chance in hell that they can secure a Linux box.

Internal firewalls?

Subnetting?

Virtual LANS?

Non-local admin access?

Disabling services?

Group policies locking down the workstation?

Nope, I'm sure these guys have an "image" they load on every server of a base XP SP3 with Spider Solitare still installed.

If they can't get that mastered, I can't wait to see how they plan on keeping 1000+ Linux boxes up to date without bringing a thumb drive to each workstation to load the updated configuration files. Linux has no answer for Group Policies.

(And don't give me the I'm anti-linux BS. I run Linux on every box in my house. I do not own a Windows license to speak of. I do, however, support it in my job.)

There is group policies in Linux
http://www.centrify.com/directcontrol/grouppolicy.asp
And there are a lot of easy ways to manage updates centrally on Linux.
By default, Linux is much more secured.
You don't need FF or AV on each station.
There is no real viruses for Linux, only couple of lab viruses and to get infected you should be programmer :)
And other fact is that Linux sysadmins have much higher "IQ" then MS MCSE, MCSA etc. Actually, from my over decade IT experience, one Linux sysadmin capable maintain at least x3 machines/servers than MS admins.
This is one of the reasons they generally paid more.

Outsourced IT

Is Logica still their outsourced IT provider?

So, based on your own link, Linux DOESN'T have an answer for group policies when it relies on a Windows Active directory server to institute group policy.

Lazy, and inevitable

I don't think it matters what systems they are running or which has more or less of whatever, if they are too lazy to proactively maintain their system then this outcome is inevitable.

I would like to know if this Logica outsourcing thing is true, someone deserves a good ball slapping.

Dimdows: Outnumbered By Malware

I think it says something, doesn’t it, that the number of different pieces of malware for Windows outnumbers the legitimate apps by 100:1 or more.

Development Manager

Why were they using Windows for operator control stations? If they're like the aluminum plant I used to work in, because their other apps are Windows-based. Time reporting, problem log, stealth porn viewer, email, sports score ticker, etc. etc.

People, not software

If they weren't capable of fixing an issue on their machines that has been preventable since Feburary, they're not going to be capable of setting up a Linux box at all.

One has to ask what sort of dimwitted technicians have to resort to replacing their systems post-infection instead of just using the easily available prevention.

It would be like them using those linux boxes to intentionally bring down the power grid and then blaming it on Linux. The only failure here is human.

I switched too because of virii

It seems that Cornflicker and such are a popular reason for switchign to Linux.

A lifetime Windows user and I had enough 2 years ago with the kids and the whole virus/malware/installupdatecleanout process and instead of buying a new computer with the new Vista, I installed Linux as a dualboot on an old laptop and neer looked back.

2yrs later and all our computers run Mandriva Linux/KDE4.3 and we run XP virtually on one where we play Chessmaster and use a work issued program once a month.

Its the same as using any other OS except I now get a new version every 6 months and I give new life to some old hardware (using a lighter desktop).

The thing that pushed me over wasnt the free part (although taht is sweet), or even the old hardware bit... it was the virus thing.

2 years of piece of mind.
Priceless.

whats a virii

the correct term is viruses,

virii is only used by knobs to try to convince other people they know what they are talking about.

Viruses Galore

Has anyone else noticed that it just so happens that every time a new windows version is around the corner, the virus rates and security hole rates for the outgoing version get a sudden spike? Gee.. how convenient Microsoft.

Sometime the a decision of consoles is not made by engineers but by the SCADA software vendor. My sympathies.

Virii

Some of us use "virii" just because it is random and funny... and yes, I know that "viruses" is the true plural. Also, "meh" is not (currently) a word... neither is "netiquitte," technically! But they are fun!

Also re-inspection of Demilitarized Zone if any is recommended.
It was the more protected internal network that got compromised here.
not the exposed DMZ.
It seems.

Intrusion Detection System like Snort monitoring unusual network activity as per rules.
And Linux Scripts running in background for Switch Port blocking on detection of such an event can help avoid isolate nodes causing trouble automatically.

Occassionally, causing false alarms etc maybe rarely.

Really secured.

An exageration

Integral Energy is an electricy retailer in the states of New South Wales and Queensland. I don't think that a virus in their computer system would have brought down the Australian power supply system or grid. Integral is just one of many retailers in these two states, and these two states do not make up the whole of Australia.

Do you even know what you are saying? Or are you simply trying to look smart pretending to know Linux security?

I will correct your statement: "If they can't secure a Windoze box, then there's A snowballs chance in hell that they can secure a Linux box." Because they don't need to do anything, Linux IS SECURED OUT-OF-THE-BOX - FAR SECURED THAN YOUR MICROSOFT WINDOZE.

of course linux is far more secure than windows

It was silly to put Windows based computers at the consoles anyway. In fact, it is silly to put windows-based computers anywhere that is mission-critical..

Linux has better solutios like as MS AD!

Linux has better, like as M$ AD, solutions for management of thery more servers/workstations:

It's Puppet (for more another UNIX systems, not only Linux), Object Languge, it's better idea like as AD!,

And it's RedHat RHN/Sattelite/Spacewalk solutions, it's provide software corporate repos services, it's better corporate Windoze WSUS server, becouse windoze make apply only M$ updates, not has automatization for management 3rd party software

And it's Novell ZenWorks, its provide complex management, like as Puppet and RHN, also, it's provide management for windows hosts (may be, better like as AD)

Please don't read MS "get the facts", it's don't facts, it's fa<censored , MS management mean all World is clinic idiots, and, pay to us it's very fail solutions since 20 years :(

We use puppet for management nearly ~4.5 k UNIX servers (FreeBSD and Linux), and, have 8(!) system administrators to provide 7/24 service for our customers!

Microsoft, Go Home!
