"It is believed that the malware won't be able to transmit the information it collects beyond the classified military network hosting the equipment; the network is insulated from the public internet."
This isn't some two-bit home network NAS we're talking about here ffs! How can they be so relaxed about it? It got in to an isolated (allegedly) network, until you can PROVE otherwise, you have to assume it can get out, not go, "well, we'll probably be ok, so bollocks to it".
What if it got there via an infected USB stick? Is it plausible to think that maybe the stick captures info from the virus the next time its attached to the network?
