Troj/Zbot-GEW in system.log?

Earlier this evening, Sophos updated itself on my Mac (10.8.4 but now 10.8.5). When it reloaded, the on access scanning didn't come back so I took the opportunity to reboot and install 10.8.5.

When the computer came back up, a short while later I noticed Sophos popup with a virus in quarantine - it dissapeared quicker than I could read but on consulting the logs I saw this:

com.sophos.intercheck: 2013-09-19 23:36:16 +0100 Threat: 'Troj/Zbot-GEW' detected in /private/var/log/system.log
com.sophos.intercheck:                              Access to the file denied

I manually ran a scan against the system.log file and it came back clean - how can Sophos detect what looks to be a windows virus, in the OSX system.log file?

As a precaution, I am running a full scan - during the running of this, Sophos again put something in quarantine and then removed it almost immediately, checking the logs again I see this:

com.sophos.intercheck: 2013-09-20 02:13:07 +0100 Threat: 'Troj/Zbot-GEW' detected in /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/hu.lproj/InfoPlist.strings
com.sophos.intercheck:                              Access to the file denied

Running sweep again this file, it came back clean?

Is this something I should be concerned about? Help!

Thanks,


Grant

  • Interesting - it's detecting a bundle file that's probably used for language translations etc.

    I'd suggest checking if the file is still detected (subsequent updates may have changed things) and if it is being detected then submit a sample of the file...

    /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/hu.lproj/InfoPlist.strings

    ...to Sophos for analysis.  Mention what it's being detected as or even exclude an extract of the log so they can tell you if it's correct or not.  How to do that...http://www.sophos.com/en-us/support/knowledgebase/11490.aspx
