“PoSeidon,” a new strain of malicious software designed to steal credit and debit card data from hacked point-of-sale (POS) devices, has been implicated in a number of recent breaches involving companies that provide POS services primarily to restaurants, bars and hotels. The shift by the card thieves away from targeting major retailers like Target and Home Depot to attacking countless, smaller users of POS systems is giving financial institutions a run for their money as they struggle to figure out which merchants are responsible for card fraud.
As if the credit card breach at Home Depot didn’t already look enough like the Target breach: Home Depot said yesterday that the hackers who stole 56 million customer credit and debit card accounts also made off with 53 million customer email addresses.
Sources within the financial industry say they’re seeing signs that Dairy Queen may be the latest retail chain to be victimized by cybercrooks bent on stealing credit card data. Dairy Queen says it has no indication of a card breach at any of its thousands of locations, but the company also acknowledges that nearly all stores are franchises and that there is no established company process or requirement that franchisees communicate security issues or card breaches to Dairy Queen headquarters.
On Monday, I had the distinct pleasure of being a guest on Terry Gross’s Fresh Air radio show on National Public Radio. I’m a huge fan of Gross’s show and was quite flattered and honored to have been invited.
Earlier this month, beauty products chain Sally Beauty acknowledged that a hacker break-in compromised fewer than 25,000 customer credit and debit cards. My previous reporting indicated that the true size of the breach was at least ten times larger. While the number of cards known to be compromised so far pales in comparison to the 40 million cards exposed by the breach at some 1,800 Target locations, new analysis suggests that the Sally Beauty breach may have impacted far more stores –virtually all 2,600+ Sally Beauty locations nationwide.
Nationwide beauty products chain Sally Beauty appears to be the latest victim of a breach targeting their payment card systems in stores, according to both sources in the banking industry and new raw data from underground cybercrime shops that traffic in stolen credit and debit cards.
In response to rumors in the financial industry that Sears may be the latest retailer hit by hackers, the company said today it has no indications that it has been breached. Although the Sears investigation is ongoing, experts say there is a good chance the identification of Sears as a victim is a false alarm caused by a common weaknesses in banks’ anti-fraud systems that becomes apparent mainly in the wake of massive breaches like the one at Target late last year.
Ever since news broke that thieves stole more than 40 million debit and credit card accounts from Target using a strain of Point-Of-Sale malware known as BlackPOS, much speculation has swirled around unanswered questions, such as how this malware was introduced into the network, and what mechanisms were used to infect thousands of Target’s cash registers.
White Lodging, a company that maintains hotel franchises under nationwide brands including Hilton, Marriott, Sheraton and Westin appears to have suffered a data breach that exposed credit and debit card information on thousands of guests throughout much of 2013, KrebsOnSecurity has learned.
An examination of the malware used in the Target breach suggests that the attackers may have taken advantage of a poorly secured feature built into a widely-used IT management software product that was running on the retailer’s internal network.
