Good samaritans and skinflints beware!
Plugging in that USB stick you found lying around on the street outside your office could lead to a security breach.
This is no secret, of course. We have all (hopefully) been aware of the dangers of inserting an unknown USB device into our computers for some time. Heck, the technique has even made it into the Mr Robot TV series.
But what may not be widely known is just how successful the tactic can be for allowing hackers to compromise your computer systems.
You never know where that USB stick has been.
