The recent hacking attack against Citigroup led to customer losses in the range of $2.7 million, according to a report by the Wall Street Journal.

In a briefing with government officials, Citigroup said about 3,400 customers suffered the loss as a result of the May security breach.

The accounts where losses occurred amount to less than 1% of the cards affected by the breach and 0.01% of Citigroup's outstanding credit cards in North America, the Journal reported.

From the article:

Citigroup announced the data breach on June 9 and said six days later that "data that is critical to commit fraud was not compromised," including Social Security numbers, birth dates and card expiration dates and security codes.

But the hackers did obtain card numbers, account names and emails that could have been used with resources that were improperly obtained through other means to cause losses, one person familiar with the breach said.

Citigroup has instituted fraud monitoring on the accounts, and replaced 217,657 cards for customers whose accounts were still active and who hadn't received new cards for other reasons.

  • Is Citi a subsidiary of Apple?

    because [i]"?data that is critical to commit fraud was not compromised,?[/i]

    sounds alot like [i]"It just works; It's built with security in mind; and Magical...Revolutionary"[/i] (funny, even the "more from Zero Day" links to Apple releasing patches for OS X security holes!!!)

      @SonofaSailor
      There is nothing in the article about apple. The article is about Citgroup.
      Re-Read the article if your so not understand. This is a serious issue for those that have CitiGroup accounts.

        @choyongpil Oh stop telling him to re-read the article, because he has a sense of humor and I bet he did read the article. Besides, you lack a sense of humor.

    These should not be customer losses. If Citigroup was hacked, they should bear the losses.

  • RE: Citigroup Attack

    Thanks for your update Ryan. I believe this is only the beginning of the fallout from these types of attacks. It is more critical than ever that corporate networks take a hard look at their network security to determine if it meets the challenges of today's attacks. One of the ways they can do this is to ensure network layer Data Leakage Prevention (DLP) to prevent the outflow of user/corporate data. Our company, Wedge Networks has focused on building such solutions for years and is leading efforts to prevent the good things from flowing out and the bad things from flowing in.

  • Document Storage Fail

    I've been there--one of my ex-employers actually lost my SS number, address, and other secure info. Digital <a href="http://www.recall.com/document-storage">document management</a> is tough, I imagine, but companies should get it together! At least there's usually a big PR backlash...
