Conficker infected critical hospital equipment
Summary
Topics
"It was not widespread, but it raises the awareness of what we would do if there were millions" of computers infected at hospitals or in critical infrastructure locations, Marcus Sachs told CNET News.com after the session. Sachs is the director of the SANS Internet Storm Center and a former White House cybersecurity official.
It is unclear how the devices, which control things like heart monitors and MRI machines, and the PCs got infected, he said. The computers are older machines running Windows NT and Windows 2000 in a local area network that was not supposed to have access to the Internet, however, the network was connected to one that has direct Internet access and so they were infected, he said.

The situation illustrates the dangers of connecting critical networks, like in hospitals and in SCADA (Supervisory Control and Data Acquisition) systems used by utilities and other critical infrastructure providers, with networks connected to the Internet, he said during the panel "Securing Critical Infrastructures: Infrastructure Exposed."
"We haven't found any nukes yet that are infected with Conficker or that are trying things like Twitter," he quipped. But "that is within the probable as we take shortcuts," he said.
"We're seeing a huge uptick in probing for SCADA systems," said Jerry Dixon, director of analysis and vice president of government relations at research firm Team Cymru. For years, the SCADA systems were separated from the public networks, but that's not the case anymore, he said.
Utilities move to remote access and other Internet-based technologies so workers can have access to the control systems when they are not at the plant and to cut costs, Sachs said. Workers have been known to access control systems using BlackBerrys for no reason other than that they can, he said.
Asked after the panel if cyberattacks had led to any utility outages, Michael Assante, chief security officer of the North American Electrical Reliability Corporation (NERC), said "none in North America."
"There is no evidence of computer compromise that led to a disruption of service," he said. "We're not immune to it; it's not hypothetical."
Government officials maintained that an electricity blackout in 2003 in the northeastern United States was not caused by the Blaster Internet worm that was circulating at the time as was suspected, but officials also were never able to reveal why it happened.

Something as serious as hospital equipment needs a secure, reliable OS. One that has a UNIX basis.
As in it is easy to see what part of your anatomy is inactive
The computers are older machines running Windows NT and Windows 2000 in a local area network that was not supposed to have access to the Internet, however, the network was connected to one that has direct Internet access and so they were infected, he said.
I mean, if you're going to let your systems go that long without patching, updating, apparently without an updated AV engine, AND connected to the internet... you might as well use something that no one wants to exploit, even if they could.
Same old song and dannnnnnce, my friend
It's the same old story
Same old story
Same old song and daaaaannnnnce yeah yeah
At the very least they should have upgraded the computers to XP, if they could handle it, if not replaced them all together.
I don't even run an OS that is no longer supported and patched by the Manufacturer. So in this case running NT, I would have upgraded them, and kept Current AV on them. Doesn't much matter if you're not connected to the net, if people are jacking disks and jump drives into the machine, at some point some one is going to bring something in.
in reality people's lives were at risk and look who is
to blame MS!
NO reason why a company cannot ditch this software and
MS Clowns for a real IT Solution Open_Source and
REAL Systems people...
Not the 'point & clickers'....
to infect it.
So, is your position that every vendor is
responsible for the consequences if there are
bugs/vulnerabilities in their software?
If so, which OS are we supposed to run? OS X
has 3 times more vulnerabilities than Vista.
Linux kernel - without any apps or added
distro crap - has 2 times as many
vulnerabilities! Sustained over the last 3
years, at least! So what are we to do?
Windows Vista is *the* operating system with
most mechanisms in place to protect users
against exploits in MS and 3rd party software.
Linux has only limited protections which are
switched off in most distros anyway. OSX has
next to none. Should Microsoft learn from them?
Or should we blame someone who ran a 10 year
old OS without patching AND let the machines
connect to the Internet?
No, the person(s) to blame are the scum who are responsible for creating Conficker.
Leaving obsolete, unpatched systems running medical equipment should be a crimial offense -- REGARDLESS of the operating system.
Unfortunately, there are just as many idiots running unpatched and insecure Linux systems -- check the number of open relays available to spammers to get a clue.
Perhaps they thought that the new imaging system was more important than replacing their well fnctioning machines only to adopt microsoft's latest and greatest for no reason.
Have you thought about it?
In the business I'm in, we have a some machines that run Windows NT and some that run Windows 2000 and there is nothing we can do about it at this time. We can't upgrade the OS because it will break the software. And we could upgrade the software, but the new software don't work with the old machines. If you happen to have a half million dollars per machine you can gives us, we would be happy to upgrade to the latest MS OS. I'm sure hospitals are in a similar situation.
I understand very well why you are not on Linux. 10 years ago Linux wasn't the viable (superior) alternative that it is today. Those who started using windows back then did it for a reason. Those who do it today do it because of their failure to stay up to date with technology. Most would call them INCOMPETENT.
BTW this...
"If you happen to have a half million dollars per machine you can gives us, we would be happy to upgrade to the latest MS OS."
was meant for Marty R. Milette not you. I should have been more clear.
In critical systems the OS and applications must be locked down and not modifiable.
I know nobody though of this in the ancient NT era.
I don't know why this is STILL not easily do-able in Vista.
The OS is not the problem. It is the management or lack thereof that is the problem.
mily/sharedaccess/default.mspx
Can completely lock down a computer. It
can be set to revert changes for selected
drives (harddisks or partitions) on every boot
but still install patches. And a wealth of more
features such as only allowing whitelisted
programs etc.
And it's free.
builds a car that catches fire in a crash,
they are SUED for it and held accountable.
This is ridiculous, everyone blames some system
admin it is the fault of the people who purchase
this software and go with a MS solution.
You can't tell me in this day and age, software
cannot be written to be ran on other platforms.
It is time to get rid of these road blocks of
securing infrastructure and go Open_Source where
problems are fixed and excuses blaming everyone
but these Windows advocates.
This puts peoples lives at risk, all because
someone wants fancy screensaves and pretty
icons.
It is time for REAL solutions not mickey mouse,
software with holes all in it that spends more
time being infected than actually used.
I must agree with you on that!
If Shuttleworth was sued for Ubuntu vulnerabilities He'd soon go bust, and then what? He chose to distribute. He pay. Ubuntu has accumulated a staggering 1200 VULNERABILITIES in the Vista timeframe.
Should Apple be sued for their triple number of vulnerabilities. Not counting their buggy apps?
http://secunia.com/advisories/product/10611/
Ubuntu at 1146 vulnerabilities and still counting. These vulnerabilities are for the OS and bundled software which (because Canonical distributes it) becomes their responsibility per the above logic.
IBM:
http://www-935.ibm.com/services/us/iss/xforce/trendreports/xforce-2008-annual-report.pdf
A report of vulnerabilities through 2008. Look under most vulnerable operating systems . The 2 at the top are OSX and OSX server. 3x the vulns of Vista.
Linux comes in at a mere 2x Vista. Note that it is Linux kernel i.e. just the bare bones Linux without any distro added software.
Microsoft has clearly upped the ante on security with SDL (Secure Development Lifecycle). Windows is also the OS with most and more complete exploit prevention techniques. Some Linux distros have some protections (although not 32bit Ubuntu). Mac OS X has virtually NONE.
Just goes to show you can't channel dead people all of the time.
Nice try from the jealous Windows user, you can't
argue with MS advocates.
The truth is there, they have to come out of the
fog to see the real facts.
No, it has been like that for the past three (3) years! Every year Linux has more vulnerabilities, every year OS X takes the crown of most vulnerable OS.
Not three years ago. For the past three years. Got that?
And you still didn't answer: If somebody takes advantage of any of those 1200 vulnerabilities, will Shuttleworth pay the damages? Should he?
Even if somebody runs an outdated Ubuntu and hasn't patched, should Shuttleworth still be liable?
As long as you don't show them here I will be calling you a liar.
If a user neglects to patch, is Shuttleworth still liable for damages caused by the bug?
The comparison of bugs seen in FOSS where the code (warts and all) is available to a closed source variation has never been all that valid. The closest thing to a fair comparison done a few years ago indicates the bug rate of Microsoft's code was way higher than that of FOSS.
Never mind, if you want to believe something else then go right on believing it.

This was in fact reported within days of the fault. It was hard to miss, once the pieces were sorted out, but there was a lot of finger-pointing in both the US and Canada about who was to blame and who should be responsible for making sure this doesn't happen again. So far as I know, no permanent solution was ever put in place. Wonder how low those Ohio wires will get THIS summer.
That's where the blame is to be directed. There are rigorous regulations governing the design of medical equipment. How did this sort of thing get through?
machines are using. If it's Windows I'll be a
gentleman and lot someone else go first.
