I'm concerned that the TDW server has been hacked and the warning is legitimate. You know we're a target.

Edit: OK, I looked into this and it's a reputation warning that Sophos gives when a site is new. TDW is not new, but with the recent consolidation of the logins for .win sites, authentication was moved to a separate server, which in turn triggered the reputation warning.

Tl:Dr: it's no biggie.
