A USB stick was on the parking lot, can someone plug it in?

Classic attack scenario: leave a USB with malware and hope a curious employee plugs it in. Answer: do not.

Try this first

  1. 1Do not plug into a work laptop. Period. Not 'just look what is on it' on a personal laptop either.
  2. 2Store the stick in a sealed bag. Do not throw away, can be evidence.
  3. 3Report to IT or your manager. Write down: where the stick was, when found, who found it.
  4. 4Has someone plugged it in already? Follow the 'suspect USB' procedure: laptop offline, Defender Full Scan, possibly isolate.
  5. 5Train your team: 'found USB = hand in, do not plug'. A few minutes in a team meeting is enough.
