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.
