For a social engineer, Dumpster diving has its benefits. He can get enough information to guide his assault against the target company, including memos, meeting agendas, letters and the like that reveal names, departments, titles, phone numbers, and project assignments. Trash can yield company organizational charts, information about corporate structure, travel schedules, and so on. All those details might seem trivial to insiders, yet they may be highly valuable information to an attacker.
