Encounter:
I encountered this word in a New York Times article on the North Korea cyber attack on Sony, the attack sent Malware which damaged Sony’s computers and also stole information. I did not know what this was, but I’ve learned in Latin previously the root Mal meaning bad and taking a part from software, so I assumed it meant bad product or data or whatever, and it turns out I am correct.
