Hi Guys,

Sent this one to the wrong group the first time, thanks J, so here goes.

Does anyone know which tool is being used for this scan. Snort has been
logging the same sequence of scans from various IPs to all Web servers on my
network, regardless that some are IIS and the others Apache. The data is
included below.

HTTP/1.0

(2) WEB-IIS CodeRed v2 root.exe access  GET /MSADC/root.exe?/c+dir HTTP/1.0

(3) WEB-IIS cmd.exe access   GET /c/winnt/system32/cmd.exe?/c+dir HTTP/1.0

(16) WEB-IIS cmd.exe access   GET
/scripts/..%252f../winnt/system32/cmd.exe?/c+dir HTTP/1.0

====================================================================

The whole scan takes from 2 seconds to under a minute in some cases, but
there is always 16 requests in the same order. Sorry if this has already
been on the list and thanks.

Regards,
Dan
