CiCi’s Pizza, an American fast food business based in Coppell, Texas with more than 500 stores in 35 states, appears to be the latest restaurant chain to struggle with a credit card breach. The data available so far suggests that hackers obtained access to card data at affected restaurants by posing as technical support specialists for the company’s point-of-sale provider, and that multiple other retailers have been targeted by this same cybercrime gang.There's a long history of this sort of thing. Both MIT and Cal Tech have traditions of students doing pranks. Often these are elaborate, and done in broad daylight (I recall one where a statue was loaded onto a flat bed trailer and driven away). Key to this was having the Guy With The Clipboard - anyone who came by to ask what they were doing was asked to sign for the "pickup".
Here we see the Bad Guys waltzing into a restaurant acting like they're Tech Support. This is a surprisingly hard problem to address.
