Someone has been rummaging through your company's trash bins seeking to find documents, diagrams, or other sensitive information that has been thrown out. Which of the following terms suits this case?

Dumpster diving is the term for rummaging through the waste/trash to recover useful documents or materials. Penetration testers and attackers may dumpster-dive as part of their efforts. In fact, emptying trash cans in a location can provide useful information even without jumping into a dumpster! Trash diving and trash engineering are not the terms used in the industry. Nothing in this scenario describes social engineering.
