Yet another reason you should not, repeat NOT, just plug in a USB drive that you find laying around! Only use ones that you, or someone you trust, has used to store data.
Also, ones that your instructor gives you at training classes I teach should be safe too. I plug those into my laptop in order to copy the class files first, so if there’s a massive problem, it’ll hit me! 😉
- Note the drives in the image above are simply random USB drives, not examples of the ones in the linked story.
