    Hi again. Because so many av:s had upgraded their engines since last fall, I made a new Jotti's av-test against snapshots. The brand new Jotti's av-test with the new specifications, there have to be AT LEAST TWO detections to minimize those False Alarms!

    2006-03 AV-test from Jotti's 6 x 100 snapshots:

    All samples in these snapshots are NOT with "ZIP", "RAR", "CAB" format or those "COM" format, that are actually old DOS samples. (most of all are with "EXE" format).

    Those snapshots were excluded, where all av:s were capable to detect the sample, but there have still to be at least two detectings in each snapshot.

    Checked as viruses/worms:

    Total ------ Set 1 ------ Set 2 ----- Set 3 ----- Set 4 ---- Set 5 ----- Set 6

    _6.3 % ----- _6 % ----- _4 % ----- 12 % ----- _3 % ----- _8 % ----- _5 %

    ================================================================================

    Detection rate:

    Total ------ Set 1 ------ Set 2 ----- Set 3 ----- Set 4 ---- Set 5 ----- Set 6

    ================================================================================

    Here are those ProActive like detections from those files MISSED BY SIGNATURE:

    43.6 % -- NOD32

    26.9 % -- BitDefender
    26.3 % -- AVG

    _7.8 % -- ArcaVir
    _7.3 % -- F-Prot
    _6.1 % -- Fortinet
    _3.7 % -- VirusBuster
    _2.9 % -- ClamAV
    _0.2 % -- UNA

    (At least ArcaVir and maybe UNA, were not capable to use their (best) heuristics in Jotti's)

    Take it always with a grain of salt, a lot of files uploaded to Jotti are either installers or corrupted files. If these were filtered out, NOD32 would have much better detection rate :) Re. installers, I found about 1000 pieces in less than a week that would be detected after being unpacked.

    I just give one example here - and just for the note - everyone who flags this file is producing a false positive because this file is innocent, i just checked it after Marcos did send it to me:

    And now the question is how much would you trust sentences like "The samples where detected by at least 2 different scanners".

    ClamAV is producing this false positive because they created a signature over the Upack unpack stub. (Worst Chase)
    QuickHeal (DNA-Scan) flags even a wet poop if it's runtime compressed
    Kaspersky is the initiator of this Signature False Positive and the rest (that's another sad story) only includes it because Kaspersky detects it. If someone would have analyzed this file in a proper way they would have noticed that it's NOT malware.

    This is the original UPACK compression tool, not malware.

    I made this limitation just because certain scanners were probably detecting too many FP:s.

    Well, like Marcos said many files are not detected because not all AVs support every type of malware, and there are many FPs. I know from my experience...files detected by KAV, VBA32, Bit Defender which were only corrupted files, or incomplete virus bodies. BD even detected the virus code copied in a HTML file as infected file. :rolleyes:

    After all, I think that ALL scanners are making FP:s sometimes, that's why at least two detectings too.

    Are you trying to say that NOD's heuristics is more accurate that the signature detectings of any other av:s? Why this, NOD was the only that was awesome in heuristics in this test.

    Damn newbies. Everyone knows you need detection by at least two antiviruses, 'XYZ and ABC' to rule out false positives. :)

    Well, here's 7 AVs detecting a corrupted file as virus.
    Even if it's infected the file is damaged and can't be excuted. ;) So you can't say 4, 5, 9, AVs detected this and it'a certainly a virus. :D

    Why, it was a malware sample, only damaged. Those cut-off corruptions often happen during mail or ftp transfer (exploit). And it is actually ok to filter such files at the gateway.

    So detection of it is ok. Those AV programs who fail to detect it rely on a signature after unpacking the sample or the part of the file which contains the signature is cut off. Unpacking doesn't work anymore because the file is corrupted.

    Another "real world" interesting test is the one performed by the nepenthes development team. It's a bit outdated now (Dec. 2005) but I did not see it mentionned on this forum.

    The intersting thing is that this test has been performed on malware captured in the wild by nepenthes sensors (and not from collector's websites such as vxh**vens) . The test has been performed on a Linux platform and it looks like not all available options (heuristics, etc) have been activated for every scanner (they do provide the command line used). Keep this in mind when looking at the results.

    As a snapshot of current malware activity, it may better reflect the real world performance of an antivirus gateway than tests that include either a huge collection of "old" malware or only new/unknown malware.

    The test is available here :
    http://nepenthes.mwcollect.org/stats:scannertest

    The summary table :

    1 Antivir 99,04% +7,07%
    2 BitDefender 96,23% +1,52%
    3 VirusBlockAde 95,17% +1,42%
    4 F-Prot 94,02% +2,39%
    4 Authentium 94,02% new
    5 Norman Virus Control 93,78% +1,19%
    6 Fortinet 87,29% +2,35%
    7 F-Secure Antivirus 85,22% +5,99%
    8 Kaspersky 85,10% +5,73%
    9 VirusBuster 82,53% +11,76%
    10 Trend Micro 76,19% +5,14%
    11 ClamAV 71,41% -0,85%
    12 NOD32 70,06% +4,05%
    13 Sophos SWEEP 68,58% +2,45%
    14 eTrust 63,97% new

    One thing to keep in mind is the relatively small cross section of threat types that are collected using a nepenthes sensor (because it only collects from a limited number of known Windows vulnerabilities) - ie almost exclusively backdoors (IRCbot/Rbot/SdBot) and net-worms (how much Korgo/Padobot!!). Also, many samples are collected very early in their lifespan and detections often improve dramatically after 24/48 hours.

    I normally scan all new samples from my nepenthes sensor on Jotti's and often find samples only detected by 1 or 2 AVs, but after submission detection is quickly added by many vendors (within 24-48 hours).

    Yes, and I do not see any easy way to develop such an automatic sensor for simulating IE vulnerabilities and browsing malicious websites (source of most adwares/spywares) or to classify automatically P2P malware...

    It'd be interesting to know what version of NOD32 you are using in order to know whether AH, runtime packers and archives were enabled by default.

    if i remember fine, nepenthes counts only exact detections, detections like "unknown virus" would not be counted as detected.

    As Ned Slider pointed out regarding the Nepenthes sensor

    "(because it only collects from a limited number of known Windows vulnerabilities) - ie almost exclusively backdoors (IRCbot/Rbot/SdBot) and net-worms (how much Korgo/Padobot!!). Also, many samples are collected very early in their lifespan and detections often improve dramatically after 24/48 hours."

    Well excuse me for speaking out of turn, but isn't this exactly what we want our AV's etc to do. A early detection as possible, that's what i want anyway, i don't know about everybody else !

    So looking at the chart from those tests, at that moment in time anyway, who would you like to have in your PC ?

    1 Antivir 99,04% +7,07%
    2 BitDefender 96,23% +1,52%
    3 VirusBlockAde 95,17% +1,42%

    Maybe not the one you have now ! Lucky me i've got the top 2 in mine.

    Yes i'm perfectly aware that it was a snapshot, but non the less i'm sure lots of people will be very surprised with the results. Look where you know who and you know who are placed !

    It would be very interesting to see a brand new test done, and how they all now compare.

    I too would like to see a test with AH, runtime packers and archives enabled, otherwise the test results cannot be treated seriously.

    As StevieO correctly recognizes, it's only a snapshot.

    I see many samples that I collect on my nepenthes sensor that are only detected initially by Dr. Web, but yet I still choose KAV as my AV. Why, because that's just one class of sample and I don't base my decision on a single case.

    And another point, all of these threats identified by nepenthes may simply be totally eliminated by being fully patched or running a firewall - you don't actually need an AV to protect against any of them. So, IMHO it's a somewhat pointless discussion.

    Early detection though is something that's very difficult to quantify. For example, AV-Comparatives uses ~250,000 samples excluding Dos and other malwares, but how many do you think are recent (ie, collected within the last 24-48 hours). Virtually none relative to the sample set, so a product could easily achieve a score of 99% but fail to detect any samples identified within the last week. I think the most we can expect is that an AV vendor adds detections quickly when submitted to them. So long as AV products use definitions, they're always going to be playing catchup and with the rate new malware is appearing (approximating Moores Law - doubling every 18 months) it's only going to get harder. You have to wonder at what point the smaller companies are no longer going to be able to keep up.

    I'd merely wanted to add that we've just discovered that NOD32 running at Jotti's hasn't been using heuristics for quite long time. We are now working with them on a fix, so take these results with a pinch of salt.
