    Krebs on Security

    Krebs on Security
    Equifax Inc. said today an investigation into information stolen in the epic data breach the company disclosed on Sept. 7 revealed that intruders took a file containing 15.2 million UK records.

  • Equifax Breach Fallout: Your Salary History

    Krebs on Security
    In May, KrebsOnSecurity broke a story about lax security at a payroll division of big-three credit bureau Equifax that let identity thieves access personal and financial data on an unknown number of Americans. Incredibly, this same division makes it simple to access detailed salary and employment history on a large portion of Americans using little more than someone's Social Security number and date of birth -- both data elements that were stolen in the recent breach at Equifax.
  • Fear Not: You, Too, Are a Cybercrime Victim!

    Krebs on Security
    Maybe you've been feeling left out because you weren't among the lucky few hundred million or billion who had their personal information stolen in either the Equifax or Yahoo! breaches. Well buck up, camper: Both companies took steps to make you feel better today.

    Yahoo! announced that, our bad!: It wasn't just one billion users who had their account information filched in its record-breaking 2013 data breach. It was more like three billion (read: all) users. Meanwhile, big three credit bureau Equifax added 2.5 million more victims to its roster of 143 million Americans who had their Social Security numbers and other personal data filched in a breach earlier this year. At the same time, Equifax's erstwhile CEO informed Congress that the breach was the result of even more bone-headed security than was first disclosed.

    To those still feeling left out by either company after this spate of news, I have only one thing to say (although I feel a bit like a broken record in repeating this): Assume you're compromised, and take steps accordingly.
  • USPS ‘Informed Delivery’ Is Stalker’s Dream

    Krebs on Security
    A free new service from the U.S. Postal Service that provides scanned images of incoming mail days before it is slated to arrive at its destination address is raising eyebrows among security experts who worry about the service's potential for misuse by private investigators, identity thieves, stalkers or abusive ex-partners. The USPS says it hopes to have changes in place by early next year that could help blunt some of those concerns.
  • Here’s What to Ask the Former Equifax CEO

    Krebs on Security
    Richard Smith -- who resigned as chief executive of big-three credit bureau Equifax this week in the wake of a data breach that exposed 143 million Social Security numbers -- is slated to testify in front of no fewer than four committees on Capitol Hill next week. If I were a lawmaker, here are some of the questions I'd ask when Mr. Smith goes to Washington.
