Dumpster Diving

The sign on the can says Litter Only. No Household Trash. No Business Trash. $100 Fine.

Dumpster diving is one of the oldest techniques in physical intelligence collection. Attackers go through discarded materials looking for anything useful — printed emails, org charts, vendor invoices, handwritten passwords, old badges, decommissioned hardware that was never wiped. The assumption that throwing something away makes it gone is one of the most persistent and exploitable beliefs in information security.

Most offices shred what looks sensitive and bin everything else. Most people make that call in two seconds without thinking about it.

The city keeps moving. Nobody looks twice at someone going through a trash can in New York.
