  • Thieves Cash Out Rewards, Points Accounts

    Krebs on Security
    A number of readers have complained recently about having their Hilton Honors loyalty accounts emptied by cybercrooks. This type of fraud often catches consumers off-guard, but the truth is that the recent spike against Hilton Honors members is part of a larger fraud trend that's been worsening for years as more companies offer rewards programs.

    Many companies give customers the ability to earn "loyalty" or "award" points and miles that can be used to book travel, buy goods and services online, or redeemed for cash. Unfortunately, the online accounts used to manage these reward programs tend to be less secured by both consumers and the companies that operate them, and increasingly cyber thieves are swooping in to take advantage.

  • ‘Spam Nation’ Publisher Discloses Card Breach

    Krebs on Security
    In the interests of full disclosure: Sourcebooks, the company that on Nov. 18 is publishing my upcoming book about organized cybercrime, disclosed last week that a breach of its Web site shopping cart software may have exposed customer credit card and personal information.

    Fortunately, this breach does not affect readers who have pre-ordered Spam Nation through the retailers I've been recommending -- Amazon, Barnes & Noble, and Politics & Prose. I mention this breach mainly to get out in front of it, and because of the irony and timing of this unfortunate incident.

But a recent spike in malicious software capable of infecting and jackpotting ATMs is shifting the focus away from innovative, high-tech skimming devices toward the rapidly aging ATM infrastructure in the United States and abroad.

    The U.S. Justice Department has piled on more charges against alleged cybercrime kingpin Roman Seleznev, a Russian national who made headlines in July when it emerged that he'd been whisked away to Guam by U.S. federal agents while vacationing in the Maldives. The additional charges against Seleznev may help explain the extended downtime at an extremely popular credit card fraud shop in the cybercrime underground.
