Best Buy, which was among the 100 or so companies hit in the recent Epsilon breach, is responding to a second consecutive breach at the hands of one of its vendors.
The big-box electronics retailer found on April 22 that email addresses of some of its customers had been "accessed without authorization" via one of its vendors, according to a Best Buy spokesman, who declined to name the vendor. Best Buy had already parted ways with that provider prior to the discovery of the breach, he said, due to a "strategic business decision."

Best Buy would not elaborate on how many customer emails were stolen or provide any details about the attack. It's unclear whether the latest breach was in any way connected to the Epsilon incident.
