Backoff malware that has attacked point of sale systems at hundreds of businesses may accelerate adoption of EMV chip and PIN cards and two-factor authentication as merchants look for ways to soften the next attack. Chip and PIN are a big thing, because it greatly diminishes the value of the information that can be trapped by this malware, said Trustwave, a security company that estimates about 600 businesses have been victims of the new malware. The malware uses infected websites to infiltrate the computing devices that host point of sale systems or are used to make payments, such as PCs, tablets and smartphones. Merchants can install software that monitors their payments systems for intrusions, but the thing is you can’t just have anti-virus programs and think you are safe. Credit card data is particularly vulnerable because the malware can steal data directly from the magnetic stripe or keystrokes used to make card payments.
The point of sale system is low-hanging fruit because a lot of businesses don’t own their own POS system. They rent them, or a small business may hire a third party to implement their own point of sale system. The Payment Card Industry Security Standards Council issued new guidance this month to address security for outsourced digital payments. EMV-chip cards, which are designed to deter counterfeiting, would gut the value of any stolen data. With this magnetic stripe data, the crooks can clone the card and sell it on the black market. With chip and PIN, the data changes for each transaction, so each transaction is unique. Even if the malware grabs the data, there not a lot the crooks can do with it. The EMV transition in the U.S. has recently accelerated, driven in part by recent highprofile data breaches. Even with that momentum, the U.S. may still take longer than the card networks’ October 2015 deadline to fully shift to chip-card acceptance.
EMV does not by itself mitigate the threat of breaches. Two-factor authentication, or the use of a second channel or computing device to authorize a transaction, will likely share in the boost in investment stemming from data security concerns. The continued compromise of point of sale merchants through a variety of vectors, including malware such as Backoff, will motivate the implementation among merchants of stronger authentication to prevent unauthorized access to card data.
Backoff has garnered a lot of attention, including a warning from the U.S. government, but it’s not the only malware targeting payment card data. It is not the types of threats which are new, but rather the frequency with which they are occurring which has put merchants on their heels. There is also an acute need to educate small merchants on both the threats and respective mitigation techniques.. The heightened alert over data vulnerability should boost the card networks’ plans to replace account numbers with substitute tokens to protect digital payments. Tokens would not necessarily stop crooks from infiltrating point of sale systems, but like EMV technology, they would limit the value of the stolen data. There are two sides to the equation, the issuers and the merchants. To the extent we see both sides adopt tokenization, you will see fewer breaches and they will be less severe because the crooks will be getting a token instead of card data.

Merchant and Consumer Groups Seek Senate Support To Forego EMV Chip and Signature As Breach Concerns Rise
There’s no shortage of answers in trying to put a stop to hackers set on throwing chaos into the way consumers transact at the point of sale, or online for that matter. Yesterday, the Banking, Housing and Urban Affairs subcommittee on national security and international trade and finance got its chance to hear some of them.
During the hearing, William Noonan, deputy special agent in charge, U.S. Secret Service, noted the advances in computer technology and greater access to personally identifiable information online, which have created a virtual marketplace for transnational cyber criminals to share stolen information and criminal methodologies. As a result, the Secret Service has observed a marked increase in the quality, quantity, and complexity of cyber crimes targeting private industry and critical infrastructure. These crimes include network intrusions, hacking attacks, malicious software, and account takeovers leading to significant data breaches affecting every sector of the world economy.
The recently reported data breaches of Target and Neiman Marcus represent only the most recent, well-publicized examples of this decade-long trend of major data breaches perpetrated by cyber criminals intent on targeting the nation’s retailers and financial payment systems. The increasing level of collaboration among cyber-criminals allows them to compartmentalize their operations, greatly increasing the sophistication of their criminal endeavors and allowing for development of expert specialization. These specialties raise both the complexity of investigating these cases, as well as the level of potential harm to companies and individuals.
So how should the industry react to prevent further breaches? Those opinions provided during testimony at the hearing varied widely, though both consumer and merchant groups would like the card networks to give up requiring only signatures for smart card purchases at the point of sale.
Consumer program director at the U.S. Public Interest Research Group, called for myriad of changes, citing that the greater risk from the recent breaches is less related to identity theft than it is to fraud on existing accounts, and he said it’s time for players on both sides of the transaction to focus more on protecting consumers than on managing their own risk.
Until now, both banks and merchants have looked at fraud and identity theft as a modest cost of doing business and have not protected the payment system well enough. They have failed to look seriously at harms to their customers from fraud and identity theft -including not just monetary losses and the hassles of restoring their good names, but also the emotional harm that they must face as they wonder whether future credit applications will be rejected due to the fraudulent accounts.
As a first step, Congress should institute the same fraud cap, $50, on debit/ATM cards that exists on credit cards, or eliminate the $50 cap entirely, since it is never imposed because of the zero-liability policies issuers have voluntarily have imposed. Congress also should provide debit and prepaid card customers with the stronger billing-dispute rights and rights to dispute payment for products that do not arrive or do not work as promised, just as many credit card users enjoy.
Congress should endorse a specific technology, such as EMV smart cards and if it does, require the use of PINs when initiating smart card transactions. The current pending U.S. rollout of chip cards will allow use of the less-secure chip-and-signature cards rather than the more-secure chip-and-PIN cards. Why not go to the higher-and-PIN authentication standard immediately and skip past chip and signature? There is still time to make this improvement.”
Retailers have spent billions of dollars on card-security measures and upgrades to comply with PCI card security requirements, but it hasn’t made them immune to data breaches and fraud. The card networks have made those decisions for merchants, and the increases in fraud demonstrate that their decisions have not been as effective as they should have been.
The card networks should forego chip and signature and go straight to chip and PIN. To do otherwise would mean that merchants would spend billions to install new card readers without they or their customers obtaining PINs’ fraud-reducing benefits. We would essentially be spending billions to combine a 1990’s technology chips with a 1960’s relic signature in the face of 21st century threats.
