The breach reportedly affects one of their four locations.

Legal Notices: Bistro Burger – Legal Notice of Potential Security Incident (3.9.15)

We recently confirmed that unauthorized individuals or entities installed malicious software on computer systems used to process credit card transactions at our Mission Street Bistro Burger location, located at 201 Mission St., San Francisco, CA 94105. The incident may have compromised payment card data of visitors that made credit card purchases at the Mission Street location between October 2, 2014 and December 4, 2014, including name, payment card account number, card expiration date and security code. While we do not know whether a particular customer’s personal information has been or will be misused, as a precaution we are providing this notice to tell customers about the incident and call their attention to some steps that they may take to help protect themselves.

We sincerly regret any frustration or concern this incident may cause. We have taken steps to help prevent this type of incident from recurring at our restaurant. We contained the incident by replacing the computer hard drive that was targeted by the malicious software, reconfiguring our point-of-sale environment, and installing firewall protection for our servers.

We want to make customers aware of steps they can take to guard against identity theft or fraud. At this time, we recommend that customers review their credit and debit card account statements as soon as possible in order to determine if there are any discrepancies or unusual activity listed. Customers should continue to monitor their statements for unusual activity going forward. If they see anything they do not understand or that looks suspicious, or if they suspect that any fraudulent transactions have taken place, they should call the bank that issued their credit or debit card immediately.

If you believe you may have been affected by this incident and have additional questions or concerns, you may call 415-533-1115 between the hours of 9:00 AM an d 5:00 PM (Pacific Time), Monday through Friday. Again, we are sorry that this incident occurred and for any worry it may cause our customers.
