Social engineering a bank robbery

From Ernesto Londono and Clarence Williams’s “Md., D.C. Banks Duped By Phony Cash Courier” (The Washington Post: 12 January 2008):

And on Thursday, about 9:30 a.m., a man dressed as an employee of the security company Brink’s walked into a Wachovia branch in downtown Washington and walked out with more than $350,000.

The man had a badge and a gun holster on his belt, said Debbie Weierman, a spokeswoman for the FBI’s Washington field office. He told officials at the bank, at 801 Pennsylvania Ave. NW, that he was filling in for the regular courier.

About 4 p.m., when the real guard showed up, a bank official told him that someone had picked up the cash, D.C. police said. The guard returned to his office and told a supervisor that he did not make the pickup at the bank. The supervisor called a Wachovia manager, who in turn notified authorities. Police were called nearly 11 hours after the heist.
