Defeating the Ghost Army – or protecting your business with a layered security strategy

by Guest Contributor 2 min read June 13, 2014

It’s no secret that e-commerce merchants, retailers, and financial institutions are prime targets for these digital ghosts as they look to quickly monetize their recent data heist. Unfortunately, many organizations are still scrambling to deploy proper defenses. So how do you defend against an unregulated, networked enemy intent on inciting chaos and filling their bank accounts? Following any data breach, it is essential that organizations gain complete visibility of their customers and transactions across channels.

Once a breach has occurred, it is critical for organizations to perform a forensic review of the attack to identify and understand all of the potential points of vulnerability, what data was stolen and how that data was transmitted back to the attackers. What can be more concerning is that the initial scope may quickly expand into something much larger. This makes it essential that retailers and financial institutions rapidly gain complete visibility of their customer data and transactions across channels and keep drilling-down until the root cause can be identified and protected against a repeat attack.

Unfortunately, that type of consolidated view does not exist in most companies. Organizations need to ask themselves some serious questions.

  1. Do you really know who is logging into your customers’ accounts? Without realizing their data has been compromised, consumers can fall prey to personalized phishing attacks and “give away the keys” to their accounts.
  2. How can you be certain a VIP customer is really behind a high-dollar transaction being rushed to an overseas address? No one wants to decline legitimate orders from loyal customers; but with revenue, reputation and brand equity at stake, no one can afford to ignore the potential risk.
  3. What controls are in-place to ensure that a fraudster in Malaysia isn’t using legitimate identity data and an anonymous proxy to submit credit card applications that are a perfect match to credit bureau data? Or to alert when a long-standing offline banking relationship suddenly enrolls online? Once access is established, address and other data can be updated and sold to the highest bidder in underground forums.

All of these questions can be addressed through the combination of complex device intelligence, a powerful risk engine and support from industry-leading experts in fraud and risk management.

Even after a breach has occurred, the risk can be managed. First, consumers need to be informed on how to protect themselves from sophisticated use of their data. Second, arm your organization with a layered security strategy that includes device intelligence. This will prepare you for the onslaught of compromised card usage, fraudulent enrollments, phishing attacks and attempted account takeovers that follow in the wake of a data breach.

The Email Address as Your Most Powerful Identity Signal

The why behind Experian's acquisition of AtData What happens when a comprehensive email intelligence database joins a global leader in data, analytics and fraud prevention? The acquisition of AtData adds 25+ years of building a complete view of email as an identity signal. Financial institutions can recognize, engage and protect customers unlocking a new standard for the way their teams work and the customer experience. That's what Experian's acquisition of AtData delivers. How we got here Not all email addresses tell the same story. Some are newly created. Some exhibit bot-like patterns. Some are inconsistent with every other signal you have about that person. Imagine a real customer. You have a job. You shop online. You have a primary email from your employer, a personal Gmail you've used for 15 years, and an old Yahoo address you still use for shopping because you've been using it since college. You're an engaged customer who interacts with brands, makes purchases and pays bills on time. But each system sees a different version of you. When you apply for credit, the lender sees one email. When you shop, the retailer sees another. When you sign up for a service, you might use the third. For financial institutions: You slow down the approval process to manually verify identity or approve applicants without the full picture. For retailers: You can't tell which version of "customer" is the most engaged, so you either over-mail or under-serve. For fraud systems: Sees a new account created under one email and flags it as suspicious because it doesn't have the history. This was the original problem AtData was built to solve in 1999. Twenty-five years later, that problem didn’t go away, it became more complex. Email fragmentation and device sharing are more common, and identity theft is more sophisticated. Capabilities that now work together Experian has built sophisticated identity and fraud solutions backed by consumer data resources and decades of expertise in credit and risk. AtData brought the ability to assess whether an email address is trustworthy, reachable and consistent—at scale, in real time. Experian is now making email intelligence foundational, not optional. This matters for: Fraud prevention and risk management: Distinguishing a returning customer from a new threat. Knowing whether an email is newly created, exhibiting bot-like patterns or inconsistent with other identities is crucial. Compliance: Building audit trails that can explain identity decisions. Email data history and behavioral signals create the documentation needed to defend your decisions. Credit: Verifying identity in a world where traditional signals are shifting. Email signals provide a persistent, durable identifier that confirms who someone actually is. Marketing: Reaching the right person across email, mail and digital channels. Email intelligence reveals which addresses are actively engaged and reachable. Research shows email remains one of the highest-ROI marketing channels outperforming paid search and social advertising1. The problem every marketer faces: You end up burning budget on addresses that bounce, are unmonitored or are associated with users who never open mail. For credit marketing specifically, email enables faster, more targeted delivery of firm offers across channels, something that's increasingly important in a post-cookie world. "Email is a persistent identifier in a fragmented world. It's what connects a person's postal address, phones, devices, behaviors—the full picture of who they are. By embedding that into our infrastructure, we're not just adding another data point. We're fundamentally improving how businesses understand who their customers are."- Ashley Knight, Senior Vice President, Financial Services and Data Why now? AI is reshaping how decisions are made in every industry. Models are getting faster, more automated and more embedded in core workflows. But AI is only as effective as the data behind it. Fragmented data + fast models = faster, larger-scale misclassifications. In an era of synthetic identities, AI agents, deepfakes and AI-generated activity, the value of durable, persistent, real-world data signals has increased dramatically. Deloitte’s Center for Financial Services projects that generative AI could drive fraud losses in the U.S. up to $40 billion by 2027, a 32% growth rate since 2023. And email sits at the center of it with business email compromise already being one of the most common and costly fraud types. People change phones, move homes and swap devices, but they often hold onto their email for years. That's the signal that protects your business, and the one we've built into the core of how we help you make decisions with confidence. View the press release here
