Neiman Marcus and Target are not the only US-based retailers that suffered data breaches last year. Reuters has learned that at least three other smaller retailers were targeted by hackers at the end of 2013.Sources familiar with the matter have told the news agency that the other victims are companies with outlets in malls. None of them have been named.
Furthermore, it’s believed that others were also targeted by cybercriminals earlier in 2013. In April and August, Visa urged businesses to take steps to protect themselves against cyberattacks that leveraged “memory parsing malware.”
It’s uncertain if Target took Visa’s advice. However, experts say the measures might have been in vain, since the attack aimed at the retail giant was far more sophisticated than the one described by Visa.
Target has only now confirmed that the attackers installed a piece of malware on the company’s POS registers in order to steal large amounts of personal and financial information.
