An online retailer of posters, prints and framed art on Saturday alerted customers that hackers had gotten into website to access credit card accounts. But the company offered assurances that it has beefed up security to avoid future attacks.
Art.com, which operates websites including Art.com and Allposters.com, said it is investigating the intrusion and asked its clientele to be more vigilant.
The Art.com chief said the cyberspace criminals gained systems entry despite "multiple security layers" and accessed some credit card transaction from July to September.
"To date, the company is unaware of any unauthorized use of those credit card numbers or any attempted identity theft related to the intrusion," a company statement said.
