마스터카드·비자카드 220만계좌 해킹(cnn.com)

마스터카드와 비자카드의 220만개 계좌가 해킹 당했다.

양사의 발표에 의하면 해커가 신용카드 거래 시스템에 침입해 계좌에 접근했다고 전한다. John Abrams 비자카드 대변인은 해킹된 비자카드 계좌 중 사용된 것은 아직 없다고 밝혔다. 이번에 해킹된 계좌는 미국 전역의 비자 및 마스터카드 연결계좌 5억6천만개의 약 0.4%에 해당된다.

양사는 해킹된 카드를 발행한 은행에 해킹 사실을 통보했다. 그러나 얼마나 많은 은행에 해킹 사실을 통보했는지, 해킹이 지역적으로 이뤄졌는지 아니면 전국적인 문제인지 밝히지 않았다.

미국 북동부 지역의 시티즌 은행은 마스터카드로부터 해킹 사실을 통보받은 후 커드번호가 노출된 8천800개의 고객 계좌를 폐쇄했다. 마스터카드는 미 연방수사국(FBI)등 수사당국과 협력해 범인을 색출하기 위한 작업을 벌이고 있다.

NEW YORK (CNN) -- A hacker has gained access to as many as 2.2 million Visa and MasterCard accounts, the two companies announced Monday.

The hacker breached the security system of a company that processes credit card transactions on behalf of merchants, Visa and MasterCard said.

None of the Visa accounts has been used fraudulently, Visa spokesman John Abrams said.

The affected accounts make up about one-third of 1 percent of the 560 million MasterCard and Visa cards in the United States. Spokesmen for the two companies said they have notified the banks that issued the affected cards.

Both card companies have zero-liability policies, which protect cardholders from being held responsible for unauthorized or fraudulent charges.

MasterCard and Visa would not disclose how many banks they had notified, nor would they say whether the hack was a regional or national problem.

Citizens Bank, a financial institution serving the Northeast, shut down the accounts of 8,800 customers whose card numbers had been accessed after being notified by MasterCard on Friday, bank spokeswoman Pamela Crawley said. All of those accounts were safe, she said.

CNN called several leading card issuers, but only one, First USA Bank, returned calls for comment. Thomas Kelly, a spokesman for its parent, BankOne, said FirstUSA's cards were not affected and that the bank was not aware of any security problems affecting its customers.

MasterCard said it is working with authorities, including the FBI, to help identify the culprit.
