Re: gotomypc

i dealt with this site/issue about 6 months ago.  ideally, you should
not have to be bothering yourself with auditing gotomypc at all, because
no sane, responsible network admin would ever let his users connect to
gotomypc in the first place.  for information about which host network
admins need to block, go here:

(sorry about the anonymization, but i had to use it since we, of course,
block all connections to all known gotomypc hosts, IP blocks)

Has anybody dealt with the services from https://www.gotomypc.com it
seems to allow end users to completely circumvent an existing network
security infrastructure.

The user signs up with gotomypc and establishes a out bound connection
through the firewall to a go to my pc server, then there server listens
for a connection that is connected to your internal network
and the scariest thing is that the listining ports for inbound
connections are on a gotomypcserver so how would you even audit?.
