Online attackers breached the security of a server at digital forensics firm Guidance Software and stole the account information of nearly 4,000 customers, the company acknowledged on Monday according to news reports.
The breach, which took place in November, resulted in the loss of customer names, credit-card numbers and the three-digit card verification values (CVVs), which merchants are not supposed to retain, according to reports. The company discovered the theft on December 7 and notified customers by mail. A company spokesperson was not immediately available for comment.
The breach tops a year of high-profile data thefts. Mastercard International notified customers in June that a third-party payment processor had leaked information on as many as 40 million credit-card accounts. Several other financial firms, including Bank of America, warned that unencrypted backup tapes had been lost, possibly putting customer accounts in jeopardy.
Information on as many as 54 million accounts is known to have been leaked by companies this year, according to the Privacy Rights Clearinghouse.
