Staples confirms that its retail point-of-sale systems were compromised by malware-wielding attackers. The home improvement retailer first acknowledged in October that it was investigating a suspected breach. Card brands use these alerts to directly warn card issuers of specific accounts that they believe to be compromised. To date, Staples has declined to say how many of its more than 2,000 stores in 26 countries – including 1,800 across the United States and Canada – may have been affected by the breaches.”]
