COVID-19 ‘Breach Bubble’ Waiting to Pop?

Summary: Gemini Advisory reports a drop of over 50 percent in demand for stolen card-present data since COVID-19 quarantines began, while supply has held steady because most sold data still comes from 2019 and early 2020 breaches. A 10-month breach at dozens of Chicken Express locations in Texas and other southern states exposed an estimated 165,000 cards, tied by Coalfire to the PwnPOS point-of-sale malware, and Chicken Express CEO Ricky Stuart said he did not know how many of the chain's 250 stores had chip-capable readers.
