Last Friday, the restaurant group Earl Enterprises confirmed that over two million credit cards were compromised in a breach affecting diners at Buca di Beppo, Earl of Sandwich, Planet Hollywood, Chicken Guy! and other restaurants between May 2018 and March 2019.
The company found out when security analyst Brian Krebs notified the chain that its customers' credit and debit card numbers were being sold on the dark web. (Krebs's blog post on how he discovered the breach is a must-read.)
Take it as yet another wake-up call. Last summer, a report by the Identity Theft Resource Center found that 1.7 million Americans' banking, credit or financial records were compromised at some point in just the first six months of 2018.
