Luck is very important. Like most other people I have no knowledge about how the Navy Marine Internet works, but that won't stop me from commenting. It sounds like a "turnkey" operation, with EDS managing everything. They may have 100,000 users with identical configurations (software, patch levels, etc) in one big flat network. A large homogeneous population is vulnerable to a common infection. Nachia has a very effecient scanning and infection process, particularly if your entire network uses RFC1918 address space internally.
