Yes.. I was at a meeting at work last week where we discussed this. 
Seems it works like this: The equipment mfrs have about 6 month 
turnaround on patch cycles, so your instrument is almost always 
vulnerable.  But, if you don't connect it to anything or use it as a 
browser, you're ok.  Then, someone plugs a USB stick in (that is 
infected from some other PC).. and that infects the instrument.  SInce 
the instrument isn't running anti virus (they're of limited value 
anyway, and usually have a performance impact that's unacceptable in 
embedded systems), the virus lurks there.  Then, when you DO connect to 
the network, it leaps into action, or, it infects the USB stick of the 
next poor schlub to use it.
