Millions of customer records leaked at US chain of bakery-cafe restaurants


Described by Fortune as a "masterclass in how not to behave when confronted with a cybersecurity predicament".

The security researcher who originally discovered the exposed customer data and reported it to the company in August 2017 was ignored by the company for over six months and so resorted to posting his findings publicly to compel the company to fix the security issue.

On 2nd April 2018 the company confirmed that it was notified of a data leak on its website due to a 'flaw' and that it had left the information of up to 37 million customers in plain text accessible from its website. The flaw in the website was fixed.

Confusion remains about the number of people impacted with numbers ranging between over 37 million to less than 10,000 customers. All customers who created an account to order online have had their full name, email/physical address, phone number, birthday and last four digits of their credit/debit card compromised.
