  2. A device can pretend to be a network card. This device could modify your computer’s DNS (domain name system, how you convert an IP address to a name i.e. to and directs you to insert a URL for a website to secretly redirect your traffic and steal information.
  3. A device could execute a malicious program automatically when plugged in. These devices could even infect the computer when booting up, prior to antivirus software even turning on.

How to Avoid Risk: 

  1. Never insert an unknown electronic storage device (USB Drive, Flash Card, SD Card, SIM Card, etc) into your computer.
