  • How Was Your Credit Card Stolen?

    Krebs on Security
    Almost once a week, I receive an email from a reader who has suffered credit card fraud and is seeking help figuring out which hacked merchant was responsible. I generally reply that this is a fruitless pursuit, and instead encourage readers to keep a close eye on their card statements and report any fraud.

    President Obama on Monday outlined a proposal that would require companies to inform their customers of a data breach within 30 days of discovering their information has been hacked. But depending on what is put in and left out of any implementing legislation, the effort could well could lead to more voluminous but less useful disclosure. Here are a few thoughts about how a federal breach law could produce fewer yet more meaningful notice that may actually help prevent future breaches.
