Dumpster Diving
In the most literal sense: Dumpster diving is when a social engineer searches through trash to find personal and corporate information.
They use this information to aid in a later attack. For instance, if a social engineer found a list of customer information in a company’s dumpster, they could use that information to impersonate those customers – and take over their accounts.
Lots of sensitive information can wind up in the trash!

When dealing with sensitive documents, make sure to dispose of them properly
