Chip-based credit and debit cards are designed to make it infeasible for skimming devices or malware to clone your card when you pay for something by dipping the chip instead of swiping the stripe. But a recent series of malware attacks on U.S.-based merchants suggest thieves are exploiting weaknesses in how certain financial institutions have implemented the technology to sidestep key chip card security features and effectively create usable, counterfeit cards.
Previous stories here on the proliferation of card-skimming devices hidden inside fuel pumps have offered a multitude of security tips for readers looking to minimize their chances of becoming the next victim, such as favoring filling stations that use security cameras and tamper-evident tape on their pumps. But according to police in San Antonio, Texas, there are far more reliable ways to avoid getting skimmed at a fuel station.
Much of the fraud involving counterfeit credit, ATM debit and retail gift cards relies on the ability of thieves to use cheap, widely available hardware to encode stolen data onto any card’s magnetic stripe. But new research suggests retailers and ATM operators could reliably detect counterfeit cards using a simple technology that flags cards which appear to have been altered by such tools.
The Buckle Inc., a clothier that operates more than 450 stores in 44 U.S. states, disclosed Friday that its retail locations were hit by malicious software designed to steal customer credit card data. The disclosure came hours after KrebsOnSecurity contacted the company regarding reports from sources in the financial sector about a possible breach at the retailer.
Visa this week delayed by three years a deadline for fuel station owners to install payment terminals at the pump that are capable of handling more secure chip-based cards. Experts say the new deadline — extended from 2017 — comes amid a huge spike in fuel pump skimming, and means fraudsters will have another three years to fleece banks and their customers by installing card-skimming devices at the pump.
Recent local news stories about credit card skimmers found in self-checkout lanes at some Walmart locations reminds me of a criminal sales pitch I saw recently for overlay skimmers made specifically for the very same card terminals.
A number of credit unions say they have experienced an unusually high level of debit card fraud from the breach at nationwide fast food chain Wendy’s, and that the losses so far eclipse those that came in the wake of huge card breaches at Target and Home Depot.
Many banks are now issuing customers more secure chip-based credit cards, and most retailers now have card terminals in their checkout lanes that can handle the “dip” of chip-card transactions (as opposed to the usual swipe of the card’s magnetic stripe). But comparatively few retailers actually allow chip transactions: Most are still asking customers to swipe the stripe instead of dip the chip. This post will examine what’s going on here, why so many merchants are holding out on the dip, and where this all leaves consumers.
Several sources in the financial industry say they are seeing a spike in fraud on customer cards used at ATMs in Mexico. The reason behind that apparent spike hopefully will be fodder for another story. In this post, we’ll take a closer look at a pair of ATM skimming devices that were recently found attached to a cash machine in Puerto Vallarta — a popular tourist destination on Mexico’s Pacific coast.
In October 2014, KrebsOnSecurity examined a novel “replay” attack that sought to exploit implementation weaknesses at U.S. financial institutions that were in the process of transitioning to more secure chip-based credit and debit cards. Today’s post looks at one service offered in the cybercrime underground to help thieves perpetrate this type of fraud.
