That's f#ing hilarious statement...

You'd be amazed what you can use to detect that somebody is trying
something nefarious.  Some co-workers of mine wrote code that was not
only able to tell when a mobile device was being hit with an nmap scan
or other attack, but identify what sort of nmap scan or attack it was...

... based on the drain pattern on the device battery.
