Inside Loyalty Fraud 2.0: The Growing Threat to Airline, Retail, and Hotel Rewards Systems

Loyalty programs sit at the heart of many business models. From airline miles and travel rewards to frequent-buyer programs at retail and food service businesses, these systems are designed to keep customers coming back while generating rich insights into their purchasing behavior.  All the value that makes these programs so powerful also makes them vulnerable, creating a growing landscape of risk.

The inherent weaknesses of many loyalty programs — from comparatively weak security controls to the challenge of tracing users once points are redeemed — create real exposure for both consumers and businesses. These gaps haven’t gone unnoticed. Cybercriminals increasingly view loyalty ecosystems as ripe targets for fraud, account takeover, and theft. 

Successful attacks don’t just drain points – they erode customer trust and can inflict reputational damage on the companies involved. Stopping loyalty fraud and abuse means strengthening elements of defenses that may otherwise be neglected, including behavior-based monitoring, bot mitigation systems, and protection around point redemption workflows. 

Getting ahead of loyalty fraud can be a powerful differentiator for your company, helping you establish a trustworthy reputation and ensuring your rewards programs do their job of promoting repeat business.

Why are cybercriminals focusing on loyalty fraud?

Criminals recognize the value of loyalty programs, exploiting them through account-takeover attacks, points theft, and other forms of abuse. Several factors make these programs especially attractive targets, creating a perfect storm of opportunity for fraudsters:

• High value, with less attentiveness: When redeemed for high-ticket items or gift cards, loyalty points have a great deal of monetary value. Despite this potential, customers don’t watch their point balances as attentively as their bank balances.  
• Less advanced defense systems: Defenses protecting loyalty points are weaker than those around financial accounts. Bank accounts are overseen by the financial industry, which has spent years developing strong defenses that can meet federal regulations. In loyalty, the onus is on merchants to protect points.
• Accounts are vulnerable to Account Takeover (ATO): Customer logins to loyalty accounts typically use standard email and password systems, not multi-factor authentication (MFA) or passkeys. This means criminals can try everything from phishing to credential stuffing to break in.
• Automation makes attacks scalable: Equipped with automated bot networks, attackers can attempt to compromise huge volumes of loyalty accounts simultaneously, with little manual effort on their part.
• Traceability is a challenge: Redeemed points are notoriously difficult hard to trace. Once a criminal has effectively “laundered” their attack by converting stolen points into goods or services, it’s difficult to continue pursuing them, making it challenging for organizations to investigate or recover losses.
• The loyalty space is growing: Focusing on loyalty theft is becoming increasingly appealing to criminals as more companies adopt rewards programs. Developing new attack techniques now offers a far greater potential payoff. As loyalty programs grow in value and scale, the return on investment for criminals continues to rise, making these schemes an increasingly attractive target

How do attacks on loyalty programs work?

Criminals rely on three primary attack methods to exploit loyalty-point systems. When combined, these tactics form a repeatable fraud cycle that continually generates value for bad actors. For merchants, understanding each stage of this cycle is essential to recognizing vulnerabilities and disrupting attacks before they escalate:

• Bot farming: Bots automate the process of loyalty fraud. Common activities such as farming fake customer accounts, harvesting promotional codes, and launching ATO attacks (see below) are now achievable at scale with minimal effort. Bots make quick, efficient use of massive volumes of stolen information as part of loyalty fraud schemes.
  
• Account takeover: Account-takeover attacks — whether driven by brute-force techniques like credential stuffing or social-engineering tactics such as phishing — are especially effective against customer accounts that lack multifactor authentication. Once in, fraudsters can often steal points before customers check their balances, locking out the real account holder and preparing to redeem the points for their monetary value.
  
• Fraudulent redemptions: Fraudsters who successfully steal loyalty points can quickly convert them into cash-like value by exploiting redemption channels with weak security controls. These vulnerable flows give attackers an easy path to liquidate stolen points before organizations even realize anything is wrong. That could mean rapidly exchanging the points for gift cards, hotel stays, flights, or physical or digital goods. Alternatively, fraudsters can use unrelated “mule” accounts to launder the points or sell them on the dark web.

Building account protection defenses to limit loyalty fraud

Before diving into specific fraud prevention tactics, it’s critical to step back and look at loyalty fraud through a holistic lens. Fraud in loyalty programs is not simply a checkout or redemption problem, nor is it something that can be effectively addressed only where points change hands. To accurately detect abuse and respond with the right level of friction, organizations must connect data across the entire customer lifecycle — from account creation and login behavior to earning activity, purchase history, and redemption patterns.    

By joining loyalty behavior with checkout and broader commerce signals, businesses gain a complete, contextual view of customer activity, making it far easier to distinguish good customers from bad actors, enabling more precise fraud detection, smarter risk decisions, and targeted step-up controls  — forming the foundation for effective loyalty fraud prevention strategies. 

Fraud prevention strategies for loyalty programs must be as multi-faceted as the fraud cycle itself. When it’s time to develop such a program for your organization, it’s important to combine tools and methodologies that can stop potential attacks at the various steps of the process. Useful defenses include:

• Bot mitigation: You can detect and prevent bot activity by implementing rate limiting, reputation and velocity checks, behavioral biometrics, and integrity checks aimed at browsers and devices. 
• Authentication and identity controls: Strong upfront controls go a long way in stopping low-effort account-takeover attempts. Multifactor authentication and device-fingerprinting signals can block a large share of automated attacks, while risk-based authentication adds another layer by escalating defenses when behavior looks suspicious. Encouraging — and when possible, enforcing — good password hygiene further reduces the pool of vulnerable accounts.
• Account behavior monitoring: Systems that search for anomalous activity are more effective if they trigger not just at login, but also during actions like large redemptions, transfers, or profile changes.
• Redemption hardening: You can prevent redemption from vulnerability by implementing friction in the form of MFA or delayed fulfillment. Limiting high-risk redemption types, like gift cards, and closely monitoring likely mule accounts with minimal activity history further helps shut down attackers’ ability to convert stolen points into value.
• Architecture strengthening: Building new defenses into your loyalty system to reflect their new status as a target can help lower risk. This could mean centralizing your risk engine to detect signals from across the customer journey, protecting APIs, segmenting high-value accounts, or monitoring credential leaks.
• Customer-facing defense: Changes that directly affect customer interactions can include proactive alerts around suspicious activity in loyalty accounts, as well as security education, and the implementation of easy account recovery workflows.
  

Making account protection part of anti-fraud measures

To take a stand against points fraud, you don’t have to make your business’s loyalty program totally impenetrable — in any case, no system is 100% impossible to crack. A primary goal of modernized defenses is to make the fraud cycle so difficult or costly to carry out that attackers give up due to a low ability to monetize their crimes.

Achieving that balance, through a combination of updated tactics and capable technology, can transform your company’s effectiveness against a rising tide of loyalty fraud.
