  • 1.  SBG False Negative

    Posted Mar 08, 2010 01:15 PM
    I received a report of a false negative from SBG.  The message audit log shows the following:

    There a couple interesting things to note about this one.  First, the message contents are quite obviously spam:

    At medrx got top brand name non generic like Cialis Vicodin Phentermine Xanax and more for less than your local pharmacy from home with no doctor hastles with extremely prompt ordering and descreet shipping.

    Also, the policy for this recipient is using the default, which normally catches things with keywords like this.

    We have the "cannot retrieve LiveUpdates except for rapid response updates" bug currently affecting us.  Since switching to the rapid response updates, I've been noticing this stuff more and more.  I was advised that the upgrade for SBG 9 will resolve this bug.  Is there an updated release date for the version 9 update?  Anything else I can do to help prevent this sort of stuff from getting through?

    Thanks!

    Hi Mike,

    The best thing is to submit samples to Symantec as per the following KB:

    http://service1.symantec.com/support/ent-gate.nsf/docid/2005012415180263

    Additionally, please take a look at the following KB for some useful advice:

    http://service1.symantec.com/SUPPORT/ent-gate.nsf/docid/2008080612113754

    SBG version 9 is coming soon; most likely this month.  A new feature being introduced in SBG version 9 called "Probe Accounts" should help in identifying certain attacks that are specific to customers.

    Regards,

    Adnan
