Hackers breached a number of HSBC (0005) customer accounts in the United States in October and accessed information, the bank has revealed in a regulatory filing.
The bank said the online accounts were breached between October 4 and 14, and it was not clear whether the attackers have tried to make use of the data to steal savings.
"HSBC regrets this incident, and we take our responsibility for protecting our customers very seriously," an HSBC spokeswoman said. "We have notified customers whose accounts may have experienced unauthorized access and offered them one year of credit monitoring and identify theft protection service." It was not clear how many accounts were breached or whether any money was stolen. However, HSBC reported that the bank believes that fewer than 1 percent of its American clients were affected, adding that those thought to have been exposed had been contacted.
