    It seems very interesting. It attacks MBR and destroys it and also encrypts ur data so that u can,t access it( ransomware type?). I will love to test it against:

    CIS
    GesWall
    DefenceWall
    ThreatFire etc

    Also it may be a good challenge for IRS like Eaz-Fix, Returnil, SD etc

    What do you guys think? I have grabbed the sample already. :p :p

    I can,t do any testing on request as i have no VM that is necessary due to the very nature of this malware.

    Yeah saw those links, bad karma !

    When i get back to my XP PC hopefully later on this week, or next, i might test it on Returnil. That is, if they can fix the Restore points issue. At the moment it only appears to pertain to Vista, i never had probs on XP, but i'd rather wait and be sure !

    Anyways, if you and others test it on various Apps in the meantime, that could be very revealing.

    I tested as follows:

    First I didn't check the encryption part, but it wipes out the disk that's for sure.


    Shadowdefender. Protects the system just fine.

    Malware Defender. Protects if you know to block it from either running or block direct disk access.

    Sandboxie. But of course system is protected just fine.

    Online Armor++

    1) Detects it as malware
    2) Protects system if you block it as in MalwareDefender.
    3) Protects the system if you allow everything, but use RunSafe.

    Pete

    Edit: Just reran it and saw no evidence of encrypted files. Doesn't make much sense to encrypt stuff if you are going to destroy the disk, I guess.

    Regretfully I can't test against anything else. Partly it's time, partly, getting trials that will still run. Very time consuming.

    OK, I have analyzed the worm a bit. Very interesting indeed. It does two actions mainly.

    1- Destroys MBR
    2- Encrypts data files( txt, xml, doc, zip etc) so u lose ur data

    Tested GesWall, SBIE and partially CFP

    SBIE- Pass
    GesWall- Pass
    CFP- MBR access intrecepted( i did not test whether it can block it effectively or not but I think it will pass here)
    data file encrption will be intercepted if u add data files( txt, doc, zip) etc into ur protected files( it,s not feasible though in day o day use of ur system) or put ur data files in a confidential folder( with custom rules for this folder)- again I did noot test it completely and did not test whether it can block it effectively or not but I guess it can. May be I can test it later. It needs time that I lack.

    Come to think of it, me neither :)

    Destroying the MBR makes it impossible to access data on the OS partition, does it encrypts files on other partitions?

    Cheers Kees

    Reads this. Yes it does encrypt data on other partitions as well.

    Even if MBR is destroyed u can read ur data by booting from other media. But after this encryption, it,s not possible.

    @ rdsu, from Pete's post #9 above - a good reason to have 'Run Safer unknown programs by default' turned on.
    Note point 3) - even if you allow Run Safer stops it doing anything.

    Some Chinese safety ethusiasts have tested this POC by using MD and EQS,they post the blocking log which indicated the primary behaviors:
    1. attack MBR,run conime.exe
    2. change the .txt, .xml,.doc,.zip,.asp(all the text files that are not 0 byte and some compressed files) into encrypted .gz files
    3. delete the orginal file itself

    So the key to interception:
    1.protect MBR, watch out for any access to disk by strange executables;
    2. protect overall important files if possible.

    BTW:this executable can't run as expected in WIN7

    Great, but what if they didn't - and what about some future threat? Could happen to any AM product. That's why I've finally began to use GeSWall myself to atleast sandbox my browser. So far there's just been some hitches, but I know that I'm MUCH more secure - simply because everything is isolated. Just about two clicks directly and I'm running an installation that I trust without isolation - it's that simple.

    Ok, some more details.
    CFP- Stops it altogether.
    It protects MBR if you deny direct disk access. It also protects data files if there are appropriate rules and you deny access to those files.
    Returnil- failed and system became un-bootable.
    Eaz-Fix- passed. Only current snapshot was lost.
    Threatfire- Protects MBR and system but data files lost without any alerts.
