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.

Tokenization technology has been available to keep payment card and personal data safer for several years, but it’s never had the attention it’s getting now in the wake of high-profile breaches. Still, merchants especially smaller ones haven’t necessarily caught on to the hacking threat or how tools such as tokenization limit exposure. That gap in understanding places ISOs and agents in an important place in the security mix, it’s their job to get the word out to merchants about the need for tokenization. That can begin with explaining what it is.
The biggest challenge that ISOs will see and are seeing, is this lack of awareness of these threats that are impacting that business sector. Data breaches are happening at small businesses, and even if merchants get past the point of accepting that they are at risk, they have no clue what to do next. Tokenization converts payment card account numbers into unique identification symbols for storage or for transactions through payment mechanisms such as mobile wallets. It’s complex and not enough ISOs understand it, even though it represents a potential revenue-producer and the industry as a whole is confused over tokenization standards and how to deploy and govern them.
ISOs presenting tokenization to merchants should echo what security experts and the Payment Card Industry Security Council often say about the technology. It’s a needed layer of security to complement EMV cards. EMV takes care of the card-present counterfeit fraud problem, while tokenization deters hackers from pilfering data from a payment network database. The Target data breach during the 2013 holiday shopping season haunts the payments industry. If Target’s card data had been tokenized, it would have been worthless to the criminals who stole it. It wouldn’t have stopped malware access to the database, but it would been as though criminals breaking into a bank vault found, instead of piles of cash, poker chips that only an authorized user could cash at a specific bank.
A database full of tokens has no value to criminals on the black market, which reduces risk for merchants. Unfortunately, the small merchants have not accepted the idea or the reality and fact, that there is malware attacking their point of sale and they are being exposed. That’s why ISOs should determine the level of need for tokenization in their markets. It is always the responsibility of those who are interacting with the merchant to have the knowledge for the market segment they are in. If you are selling to dry cleaners, you probably don’t need to know much about tokenization, but if you are selling to recurring billing or e-commerce merchants, you probably need a lot more knowledge about it.
Tokenization is critical for some applications in payments. Any sort of recurring billing that stores card information should be leveraging some form of tokenization. Whether the revenue stream comes directly from tokenization services or it is bundled into the overall payment acceptance product is not the most important factor. The point is that it’s an important value to the merchant to be able to tokenize the card number in recurring billing, but ISOs sell tokenization products against a confusing backdrop of standards developed for different forms of tokenization. EMVCo, which the card brands own, establishes guidelines for EMV chip-based smart card use. It’s working on standards for “payment” tokenization with the Clearing House, which establishes payment systems for financial institutions. Both entities were working on separate standards until The Clearing House joined EMVCo’s tokenization working group to determine similarities and determine whether one standard could cover the needs of banks and merchants.
