Stop fraud without friction

How to detect and defeat modern cyber attacks

As digital transformation accelerates at an unprecedented rate, strategic initiatives such as revenue collection, customer loyalty, and brand awareness are now primarily online.

And they’re increasingly being hijacked by hackers, leading to account takeover (ATO), fraud losses, and damaged brands. Any business that operates e-commerce applications or manages user accounts of value is a target.

The Attractive ROI of Online Fraud

Attackers decide where to spend their time and resources in the same way you might evaluate the cost versus value of an important purchase. If a target is dirt cheap to compromise and the value is astronomical, it’s an easy decision. If a target is highly valuable and highly guarded, an attack requires more investment, making the cost of successful compromise higher.  

Today’s attackers have access to readily available tools, infrastructure, and compromised data, so it often costs pennies on the dollar to steal high-value data through automation. The more technology advances, the lower the costs fall, even for harder-to-obtain targets. So how do you demotivate attackers from targeting your site? Keep them guessing.

A famous bank robber, Willie Sutton, stole an estimated $2 million over his 40-year career on the run in the early 1900s. When asked why he robbed banks, he replied, “Because that’s where the money is.” If Willie Sutton were alive today, we can safely assume he wouldn’t be robbing banks anymore. He’d be defrauding applications.

The Fraud Business Is Bigger (and Smarter) Than Ever

Thanks to the low barriers to entry and easy access to resources, online fraud has become big business, and the process for mining personal identifiable information (PII) has reached industrial proportions. More than 30 billion records have been breached in the last seven years alone.

The status quo is unacceptable. Estimated online fraud losses are staggering, yet business leaders often reserve budget in anticipation of paying out chargebacks. Plus, security controls intended to thwart fraudsters can frustrate real customers, leading to abandoned transactions and lost revenue.

To protect critical assets from sophisticated cybercriminals and ensure the success of strategic business imperatives, organizations need to adapt as attackers evolve.

Today, most website visitors aren’t human. They’re bots.

While some bots are benign, like chatbots and search engines, most are bad bots used by malicious attackers to gain unauthorized access, take over customer accounts, and even commit fraud while eroding the customer experience. And they’re constantly retooling to mimic user behavior and bypass common countermeasures like CAPTCHA. Here are some of the most relevant automated attack trends, and how you can fight back against them.

Credential Stuffing: Bad Actors Compromise Real Customers

Ninety percent or more of an enterprise's online and mobile traffic can be from cybercriminals performing automated attacks with the intent to steal customer data and commit fraud.

These attacks, known as credential stuffing, can lead to account takeover and serious fraud losses, while also negatively impacting application performance and skewing analytics. And if that wasn’t enough, attackers also aim to jeopardize your customers’ trust by siphoning money and points from loyalty programs.

98.5% of requests to a customer loyalty program were attacks.

F5 has a multi-leveled approach to defeat credential stuffing – protecting over 4 billion transactions per week.

For every connection to a site or application, F5 Distributed Cloud Bot Defense creates and assigns a Device ID – a unique identifier to each device visiting your site created in real-time utilizing advanced signal collection and machine learning algorithms. Utilizing this unique identifier as well as other signals, Distributed Cloud Bot Defense can identify and stop attempts to use compromised credentials in real-time, blocking bots that emulate human behavior and fraudsters who manually hack applications to bypass anti-automation defenses.

Distributed Cloud Bot Defense: Solution Overview

F5 protects over 4 billion transactions per week from sophisticated attacks on behalf of the world’s largest companies.

CAPTCHA and Other Cybersecurity Myths That Are Hurting Your Business

Are your sites using CAPTCHA to mitigate automated attacks? If so, it’s probably not working, and it could be causing unintended consequences such as customer abandonment due to excessive friction. And with an increase in third-party CAPTCHA solving services, both automated and human powered, it has become increasingly simple to bypass CAPTCHA. Your web and mobile applications need better protection.

The last thing you want to do is base real business decisions and security outcomes on a myth, even if it does sound convincing.

Retailer Fixes Fraud Without Increasing Friction

Known for their luxury product offering and friction-free online experience, a North American retail chain prided themselves on providing a great customer experience. But the company was ravaged by automated attackers taking advantage of their streamlined system. 

After trying and failing to combat attackers with traditional countermeasures (CAPTCHA, blocking IP addresses, etc.), the retailer turned to F5 Distributed Cloud Bot Defense. After three weeks of observation, they went live with mitigation, and the results were immediate.

From day one, when F5 Distributed Cloud Bot Defense went into blocking mode, we saw a nearly 100% drop in fraud from automation.

An Adaptive Security Approach

In the following 30-day period, the retailer saved over $500,000 in fraud that would have been lost due to account takeover and gift card cracking. The attackers attempted to retool around F5's defenses, but because Distributed Cloud Bot Defense tracks hundreds of network, device, and environment signals, the attackers were easily found and blocked again.

With automated attackers repelled by F5, the origin servers saw only the human visitors—a mere 1% of the previous load. By reducing 99% of traffic, Distributed Cloud Bot Defense lifted “a huge burden off our infrastructure, which had a direct positive impact on revenue.”

This retailer was successful not only because of the initial mitigation measures, but because of the solution’s ability to adapt to changing attacker tactics. Bad actors will find a way around static security countermeasures if the target is sufficiently attractive. In fact, attackers now leverage trained artificial intelligence (AI) models to bypass security. Organizations, especially those that guard highly sensitive customer information, need to continue to hold business and technology partners accountable for ensuring the security and integrity of the application even after launch.

Fake Reservation Story: The Power of Signals & Sharing Data to Stop Application Attack

As defenses improved to block questionable behavior, attackers responded by creating tools to exploit and imitate individual users with all their nuances.

Staying ahead of shifting attack strategies will continue to be an ongoing battle. 

As fraud mitigation evolves to block increasingly sophisticated automation and minimize the ROI for bot-based fraud, attackers won’t give up. They’ll pivot to methods that are harder to identify, such as emulating human behavior, commissioning human click farms, and manually hacking applications. While automation is the main focus today, organizations should prepare themselves to fight against a hybrid of automated and human-driven fraud.

The cyber threats facing businesses today will only continue to grow. Globally, fraud loss is increasing annually in double digits. As digitization continues and more customers are seeking services online, the risk surface will expand and become even more porous. Your business can prepare for the future threat landscape by considering a cross-functional approach to security that considers top-line potential, bottom-line pressure, and customer experience together.

Considering Your Fraud Mitigation Investment

Is it enough to just spend more on tools to detect online fraud? Short answer: no. Enterprises find that despite spending billions annually on tools to detect online fraud, direct fraud losses continue to climb. Juniper Research projects that online fraud losses in aggregate will exceed $48 billion per year by 2023.

Current fraud tools require extensive configuration, generate ambiguous risk scores, and require fraud teams to develop their own rules, potentially applying a lot of friction to legitimate users and ultimately hurting revenue. For lasting protection against an increasingly dynamic attack surface, businesses need to invest in security solutions that continuously adapt to attackers without introducing friction for real customers.

Stopping automated attack traffic does more than prevent fraud; it reduces overall business costs.
