18 Mich. Jimmy John's in national data security breach
- Jimmy John's learned of the situation July 30
- 18 Mich. locations affected, including in Royal Oak, Novi, Warren
Customers at 18 Jimmy John's shops in Michigan are among others nationwide whose credit and debit card data could have been stolen in a possible security breach this summer, the chain announced Wednesday.
Officials learned of the situation July 30 and said that "it appears customers' credit and debit card data was compromised after an intruder stole log-in credentials from a Jimmy John's point-of-sale vendor and used these stolen credentials to remotely access the point-of-sale systems at some corporate and franchised locations" between June 16 and Sept. 5, according to a statement on the website.
The cards in question appear to have been swiped at the stores, not entered manually or online, Jimmy John's said.
