In late September, sandwich shop chain Jimmy John’s confirmed that criminals hacked into their point of sale systems at 216 stores and accessed customer debit and credit card information. The breach took place between June 16 and September 5. Hackers obtained the account numbers on these cards, and may have access to the cardholder name, verification number and/or expiration date. The company, based in Champaign, Illinois, said the hackers were able to obtain the login credentials from the chain’s payment technology vendor and access its point of sale system. The breach did not affect any cards used in any online order or a transaction where the card number was entered manually.
