back to article Busted! Conficker's tell-tale heart uncovered

Security experts have made a breakthrough in their five-month battle against the Conficker worm, with the discovery that the malware leaves a fingerprint on infected machines that is easy to detect using a variety of off-the-shelf network scanners. The finding means that, for the first time, administrators around the world have …

    Just a quick note

    Heh, this is Dan Kaminsky, from the story. Just to make something very clear:

    Tillmann Werner and Felix Leder are the Honeynet Project researchers who actually noticed the behavioral shift introduced by Conficker. I've been doing work in fingerprinting lately, so I saw the opportunity to make it quite a bit easier to track down infected nodes in large organizations, but again, it was Tillmann and Felix who actually designed the fingerprinting logic that ultimately all these other organizations are integrating into their vulnerability scanning systems.

    This is one small part of what's actually some very fine research about Conficker. This is their baby, I've just been helping it fly.

    At least we now know one thing it will do April 1st. Fix this fingerprint. Unless thats what security experts want and this is just a fools joke on the botnet owner to get them to do something expected on April 1.

    Does this mean ISPs will now be able to scan for customer's infected PCs and block them from their networks?

    The (L)users who did not pay attention to their security should face be made to realise that they have a responsibility to themselves and other internet users to secure their systems. Either that or swap to an OS that isn't riddled with security holes.

    Please, can we stop using this stupid argument now? Linux's superior security record is not down to obscurity. It is the majority webserver platform after all.

    It comes down to massive, continuous source code peer review and good kernel design. Windows NT lacks both and unless they open source it (and wait a couple of years for the massive refactoring effort that would follow) the writing's on the wall for this decrepit VMS clone.

    Re: Scanner instructions?

    Caveat: I am not involved with this and have only just tried this myself.

    Prerequisites: Python, py-pcapy and py-Impacket (that's *i*mpacket, it's capitalised and the font used here doesn't really make that clear). Runs fine here with python 2.5.4, py-pcapy 0.83.0_1 and py-Impacket (FreeBSD 7-STABLE).

    Run "python ./ <start-ip> <end-ip>" or use the filename of a file that contains a list of IPs you require scanning as an argument in place of start and end IPs; the example supplied is Unix format, hence lack of CRs in notepad.

    If you're using Windows, be aware that the Windows MSI Python package is compiled with VS 7.1 and the extensions you need to build (py-pcapy, py-Impacket) also need access to that compiler, so will require much buggering about with bits and pieces of visual studio if you don't have a copy. You'll also need WinPcap. You're well advised to use a *nix box to run this.

    Example output when pointed at a lappy with the server service enabled:

    It's all well and good saying "It's not hard to download Python", but I'm sure it's equally, "Not hard to have effective security in place to stop such infections", but let's not forget it isn't just corporates having problems who (hopefully) employ competant sysadmins ... so let's put that nonsense to one side and get on with dealing with the problem before the clock runs out.

    I llooked at the nmap site but couldn't see anything in the changelog which says what version I should be using, I don't care which paid for softwre will include detection, I want something I can download, run and breath a sigh of relief orknow which WAN cables to take the scissors to.

    Re: query

    If you have the server service disabled on the machine you're scanning, the No resp. is what you'll get because port 445 is closed. Conficker uses SMB and it's this that the tool is querying. IPs with no active machine on them will also show No resp.

    The code tells you what you'd get if you were infected:

    if result[1]==0x5c450000 and result[3]==0x00000057:

    print '[WARNING] %s seems to be infected by Conficker!' % ip

    retval = 1

    If you've turned off the server service on your boxen, congratulations, there's really no reason for client machines to use it. If you've turned off the server service, disabled autorun AND threatened your lusers with death if anything, anything at all connecting via USB or IEEE 1394 is found near the machines, you're *almost* immune from Conficker. If you've filled with Araldite the USB and IEEE 1394 ports on the client machines, removed all the DVD-RW drives and floppies, disabled the server service, riveted the cases shut and have a modified electric fence pulser on a stick to hand for lusers that never learn, GTFO, you're me ;o)

    I'm not a linux or un*x snob / fanboi BTW but I don't believe in putting all my eggs in one basket.

    The windows mindset is why several companys I worked for used UNIX systems in the 1st place. It prevented somebody with a machine at home thinking that they had the capability ot fix a server issues.

    Not me, Mark, I can get all of my Win clients to give either result depending on the state of the Server service, which was disabled by default here long, long before MS08-067 was discovered - any file-sharing needed goes over the central shares, not from individual machines. I was replying to the AC above who can get nothing but No resp. results. I thought it may be a firewall myself, but I'm not assuming anything because a) (s)he's posting on the Reg so (s)he's not likely to overlook such obvious issues and b) I don't fully understand the conversation the scanner is having with SMB and I haven't had time this morning to fully analyse it as an ET update buggered up the emerging.rules (line 116 if anyone's interested) and my snort inline fell over, cutting everyone off the IPv4 web.

    Interestingly, if you point this scanner at a Samba server running with everything enabled, you get the same No resp. result.

    *sigh* There is world of difference between running an obscure system and hoping an obscure security problem on a popular system isn't found.

    An obscure problem on a popular OS is a large target for malware writers. A large problem on an obscure OS is a very small target because exploits are *not* random events, worms and viruses are written for windows and not OSX/Linux for the same reason that games are written for windows and not *nix - the effort doesn't justify the ROI.

    Regardless of the security situation, running *nix hosts reduces your *risk* of being affected by malware, which is a much larger problem than being targeted individually by a skilled hacker.

    The security problem is not solved by everyone running *nix - that just moves the malware-writers' focus, but individuals *can* reduce their risk (relative to the average Windows user) by switching to a *nix based OS which doesn't have a huge target painted on it.

    I'll be interested to see if much happens after 1st April. If its bad, Apple will have a large number of smug users doing PR.

    Alright, I'm not the systems or network admin but instead just a help desk guy. I got all of the tools installed and, thanks to this thread, got the scanner working. In order to actually have a functional scan, you need firewalls dropped and port 445 opened?

    Not really - the ISPs will get as far as your router with their scan and no further. Remember the majority of folks are on broadband these days, complete with broadband router with a little thing called NAT at the front.

    Unless there's an outbreak of routers infected with Conflicker, I don't think the ISPs can do much about this. Not to mention that even though it would be done with good intentions, it's still against the Computer Misuse Act.

    Re: No resp.: xxxmachinexxx:445/tcp.

    Hi local vi, I didn't think you'd overlook that. I'm not getting any new ideas right now, although a bit more information might help someone a bit brighter come up with a suggestion. OS version? Members of a AD domain? Group policies? File and printer sharing state on the clients (I *think* this is independent of the Server service state but I haven't checked)? Any of these may affect the results.

    One thing you may want to try is remote management via the computer management tool; if that fails, either remote registry or file and printer sharing is restricted somehow. Remote registry shouldn't make a difference to the scanner, but remote management requires both services IIRC. Also check any firewall on the machine that you're running the scanner on. *nix firewalls tend to egress filter as well as ingress by default.

    I don't think you need telling but [I'm going to go into annoying arsehole mode and say it anyway -Ed] these settings would be better returned to the restricted state once you've found out why the scanner is having a hard time talking over SMB. Where there's one piece of malware with this distribution method, there's bound to be copycats. All of the discussed restrictions contribute to stopping such things. Only run what you need for day-to-day operations and disable the chaff, thereby reducing your potential entry vector surface. That's how OpenBSD got its reputation rather than by any super-secret methods that other OSen couldn't copy if pushed. There's nowt special about it other than the default settings overriding the quality, or lack thereof, of the admin ;o)

    It is now 10:30-ish AM and cyberspace as we know it hasn't come crashing down around our ears, I haven't seen a significant rise in detected spam (if anything, e-mail volume is lower than yesterday's figures), I'm not being DDoS'd and my web server doesn't seem to be getting hit by Dfind, Morfeus F-ing scanner and such crap any more than usual. Some will see that as proof that the foregoing security efforts and discussions were hype. I see it as the security experts, the Conficker Cabal, reporters making people aware and the people who worked on the various detection mechanisms having succeeded with the prevention efforts. Well done, if it's not too early to be handing out the kudos.

    Have i missed something?

    Have I missed something, or can you only get infected by Conflicker if you haven't installed the Microsoft patch which mitigates it? ie, the one which came out last October -

    If I've not missed something, Snort has had signatures to detect which machines don't have this installed for months now.

    What extra value does this new tool ad?
