A New York-based cybersecurity firm, Gemini Advisory, has said that three Canadian branches of Saks Fifth Avenue stores were exposed to a data breach of customer information. Gemini found that the stores are Sherway Gardens, Bramalea City Centre and Pickering Town Centre. Word first came Sunday from Hudson’s Bay Co. which said customer payment information may have been stolen from shoppers at certain Saks Fifth Avenue, Saks Off Fifth and Lord & Taylor stores in North America.
