Re: Interesting GUID

It may be MS RIS, as it uses client GUIDS as part of the
authentication to install MS operating systems.  Not sure if it sends
out it's own though.  A licensing server is a good guess, MS WDS may
be another possibility.


Thanks,
James

could be a licensing server, it could be some custom-build messaging
system, it could just be injecting a little randomness into the

amap probably isn't going to help in this case. i assume you've done
fingerprinting on the box using nmap/nessus/nexpose?

Maybe try sequencing the GUIDs to identify any interesting patterns?

While doing a pentest I ran across a service which responds with what looks to be a GUID.

Example 1
Connection to x.x.x.x 35000 port [tcp/*] succeeded!
{8F418F3C-4530-4198-9988-8B6E8E646991}Q?,?,?w>f???)??
                                                    ?nX?W?EOL{8F418F3C-4530-4198-9988-8B6E8E646991}EOL


Example 2
0000:  7b46 4641 3131 4334 442d 4437 4237 2d34    [ {FFA11C4D-D7B7-4 ]
0010:  4139 312d 4146 4643 2d32 4133 3534 4143    [ A91-AFFC-2A354AC ]
0020:  3331 4539 457d 1551 ab2c ae2c b077 3e66     [ 31E9E}.Q.,.,.w>f ]
0030:  fbb8 cb29 02ab f30c fc6e 5816 1dd1 0400            [ ...).....nX..... ]
0040:  0000 1800 0000 0400 0000 5786 0000 454f     [ ..........W...EO ]
0050:  4c7b 4646 4131 3143 3444 2d44 3742 372d    [ L{FFA11C4D-D7B7- ]
0060:  3441 3931 2d41 4646 432d 3241 3335 3441    [ 4A91-AFFC-2A354A ]
0070:  4333 3145 3945 7d45 4f4c                                     [ C31E9E}EOL       ]


Has anyone run across a service which act like the information provided above or could help in why or what a service 
responding with GUID information would be used for.
(especially as an external service).

Any ideas would be appreciated.
