Re: ** Re: sophie not detecting some viruses (fwd)

Vanja,

I have opened a call with Sophos Support.

  my inital incident no: EDA-19-EMR

Michele felt the need to assign yet another,
  incident no.:  EAA-19-QPG

After this inital response from support, they have forwarded
the request on to the "product manager" and I'm told "... they
will most likely need to be in contact with Vanja."

How this is going to procede is not very well defined. I'm
told the product manager will assign someone to work on the
problem and I can keep hounding Sophos Support to see what shakes
out from my end.

Anything that you can do will be appreciated.

- Bill

Hello,

Sophie is a daemonized version of Sophos, or SAVI.  Because of this, the
version of the engine that is loaded into memory must be reloaded when a
new IDE file is placed on the system.  When customers are using MailMonitor
(similar product to Sophie) they must restart the MailMonitor daemon after
adding a new IDE file.  I would imagine that the same is true for Sophie.

Please let me know if you have further questions.

Regards,
Michele Morelock
Sophos Support

Attached file:

  2004-01-19-virus-undetected-Profile-720974.html.bin

Is undetectable using sophie and the Sophos SAVI library.

Sweep does detect the virus as does Norton Anti0virus on
a PC.

What options are required to be enabled for the SAVI libraries
to identifiy the virus in the file.

Can someone with a PC and Anti-virus software test the file to
see if it is really a Virus?

  http://www.space.net/~maex/Profile-720974.html.bin

I have "turned on" every option configurable in our version of
Sophie and re-compiled and I get the same results. Others on the
vtools list, including the author, have tried the latest release
of Sophie and are having no luck either.

Our scanners have NEVER reported any "Sefex" virus / trojan
- our daily summary reports begin on 2003-04-06 and continue
  through last night.

  Sophos's description of Troj/Sefex-A:

  http://www.sophos.com/virusinfo/analyses/trojsefexa.html


Mailscan1's Virus summary for yesterday:
=======================================

  153 W32/Dumaru-A
   98 W32/Klez-H
   74 W32/Gibe-F
   45 W32/Bagle-A
   21 W32/Sobig-F
    7 W32/Bugbear-B
    5 W32/Sober-C
    2 W32/Bugbear-Dam
    1 W32/Parite-A
    1 W32/Rox-A
    1 W32/Parite-B

The other scanners had similar results with the same list
of viruses.

We have the same problem with an earlier version of sophie,
v 1.43, and Sophos 3.76NSV.


The sample file Profile-720974.html.bin:
========================================

sophie does NOT identify it as a virus:
---------------------------------------
- If a virus was identified we would have seen a line similar to:
  "Scan result  : './eicar.com' infected with virus 'EICAR-AV-Test'"

  $ sophie -d -f ~/Profile-720974.html.bin
  Initializing    : Grp* options (engine >= 2.14)
  Initializing    : Sophos engine version 2.18
  Initializing    : Sophos IDE version 3.76N (detects 86253 viruses)
  [...]

  [debug] Scanning file : '/home/bill/Profile-720974.html.bin'
  [debug] pSAVI cleaned up and released/terminated
  Cleanup         : Sophos cleaned up and terminated

sweep identifies Troj/Sefex-A virus:
------------------------------------

  $ sweep -f -archive ~/Profile-720974.html.bin
