what is a common thing to notice about scanning for conflicker? One site said a simple scan can disquish between clean and unclean ..: "Another option is to actively scan for Conficker machines. There is a way to distinguish infected machines from clean ones based on the error code for some specially crafted RPC messages. Conficker tries to filter out further exploitation attempts which results in uncommon responses" http://iv.cs.uni-bonn.de/wg/cs/applications/containing-conficker Therefore, does this mean it gives what kind of response back..closes the response or what? What "error code " will it produce?
Hosts which have been 'patched' by conficker send back a different response than those which are not infected, whether or not they've been patched with MS08-067. The python based scanner from the authors of the article quoted checks for this specific response: if (len(response)>=16): result = struct.unpack('IIII', response[:16]) if result[1]==0x5c450000 and result[3]==0x00000057: print '[WARNING] %s seems to be infected by Conficker!' % ip <snip>
Anyone input for me?
Below is a capture of the packets sent by the smb scanner tool and the associated responses from a host infected with conficker.c (note packet 16 specifically). Not sure if this really answers the questions you have, hopefully it helps a little anyway (if it doesn't, i blame lack of sleep and insufficient quantity of caffeine consumption on my part ;-) --
