In yet another shocking incident of hackers breaking into the networks of big corporate houses, it has been disclosed that Citigroup, one of the biggest name in the US banking business, had suffered a massive hack-attack in May that put the sensitive data belonging to thousands of its customers at risk.
The breach, which according to the bank itself affected not more than one percent of its customers, was first brought into notice by the Financial Times (registration required).
However, the bank which has over 21 million customers in the entire North America, even one percent of them falling victim to this breach will account for a significant damage done to its reputation on the market, and not to mention about the loss the victims may have to suffer.
According to reports, the breach had taken place at the Citi Account Online, which means the hackers got their hands on users’ names, email addresses, account numbers etc. However, other more sensitive information such as birth dates, CVV codes, social security numbers etc. could not be accessed by the perpetrators as they are kept elsewhere,
However, Citibank has come under severe criticism from various corners after their apparent reluctance to disclose the breach in the public domain came in to light.
