The world’s largest financial services network has been attacked by the hackers in Japan. Some hackers stole personal information of 92,048 Citigroup Inc. Japan credit card customers according to a report. Citi said that customer account numbers, names, addresses, personal identification numbers and card security numbers were stolen.
This is not the first time that Citigroup has suffered from Data Theft. According to a Citi disclosure in June, hackers stole nearly $2.7 million from its North American customers. Citi covered customer losses by paying $2.7 million to the affected customers.
According to some security experts, who are familiar with the matter, this attack was done by a third party vendor who had access to Citi’s internal systems. This means that there is a chance that perpetrators might have got some inside help.
Citi has started contacting all the affected customers and is advising them to change their security codes. But will this advice from the world’s largest financial services provider enough?
Citibank is one of the major banks of the world and is a consumer banking venture of financial services giant Citigroup. Till now Citi has not provided any details about the security breach or how the perpetrators managed to access its internal systems.
It seems that Citi indeed was “sleeping” when the information of customers was being stolen.
