Petco has fallen victim to a data breach after “a setting within one of [their] software applications inadvertently allowed certain files to be accessible online.” 

The setting at fault has since been fixed, but not before exposing customer data. Across several states, Petco customers had their names, birth dates, SSNs, driver’s license numbers, and bank account/payment card information exposed. 

It’s currently unclear how many people have been affected, but those involved will receive a data breach notice via email or mail providing more information and offering a year of credit monitoring services.
