New Worm Discovery - Potential Korgo Variant

["Michael Young" <mikeyoung () milestechnologies com>]

Yesterday a large client of ours was taken down by what appears to be a
Korgo variant, but I have been unable to locate any information on this
worm.  From what we have discovered, the main process is 'VDisp.exe'.  It is
spreading through unpatched systems vulnerable to the LSASS exploit, and
propagates itself through a serious of randomly chosen ports.  The worm
creates randomly generated services that initialize the process, and also
creates a registry entry in RunServices and Run to load.  I am anxious to
hear any feedback anyone has regarding this issue as we are still attempting
to reduce network traffic and alleviate any remaining issues.  I have
attached a copy of the executable (rename to .exe).

 

Thank you,
