There are a few red flags that I've noticed about this article. First off, it's pretty convenient that the GFOIS is talking entirely about e-cigarettes on a no-smoking day. After all, there are plenty of other devices that could contain malware. Heck, If I wanted to infect someone's computer, I could just give them a flash drive with an autorun.inf file with an open= key that points to a malicious executable.
Also, never in the history of computers have firewalls been able to protect people against malicous code stored on local hardware. I'm guessing GFOIS doesn't really know what these "firewall" things are, but have heard some computerphile talk about them. Then, much like Hollywood writers, they through this word into a sentence and hoped like hell they didn't just embarrass themselves (fun fact: you could actually look this stuff up before embarrassing yourself).
