Payment Fraud Has Changed. Did Your Infrastructure?

Fraud rarely announces itself. It often starts with something routine: a check that never arrives, a payment rerouted after a minor account update, a login that looks legitimate at first glance. By the time the pattern becomes clear, the damage is already underway.

In 2024, 79% of organizations fell victim to fraud attacks or attempts — and payers in both healthcare and property and casualty (P&C) insurance were squarely in the crosshairs. The threat has grown more coordinated, more adaptive, and more persistent. With GenAI projected to enable $40 billion in U.S. fraud by 2027 and deepfake fraud already up 2,137% in three years, the pace is only accelerating.

The Threat Has Changed. Most Systems Haven't.

Today's fraud doesn't look like yesterday's fraud. Attackers don't just intercept a check. They intercept it, extract the routing data, reproduce it, alter the amount, and deposit it in a different state — sometimes through a shell business registered under the same payee name to bypass Positive Pay controls.

That's not opportunistic theft. That's a coordinated operation designed to exploit every gap a payment infrastructure leaves open.  And fragmented systems leave a lot of gaps.

Most organizations manage the payment lifecycle across multiple platforms: onboarding, payment issuance, account verification, and communications running separately, each working fine on its own. But no single system sees the full picture. An address change tied to a payment reroute looks harmless in isolation. A compromised credential looks like routine activity. The signals exist — they just never connect.

Checks are a visible problem. Fragmented infrastructure is the deeper one.

Why Paper Checks Remain Fraud's Easiest Target

Even as digital adoption expands, paper checks remain one of the most exposed elements of any payment program. The vulnerabilities are built into the medium itself. Checks travel physically through the mail, display routing and account information in plain view, and pass through multiple manual handling points before funds clear.

That makes them an obvious target, with 63% of organizations reporting attempted or actual check fraud in 2024. Fraud occurs 31 times more often on checks than on real-time payment rails. Mail theft, check alteration, and identity manipulation let attackers intercept, modify, and redirect funds well before anyone notices something is wrong.

The consequences extend beyond financial loss. Paper payments slow resolution cycles, increase operational workload, and expand the attack surface. For health plans, P&C, and workers’ compensation carriers processing high claim volumes, this exposure adds up fast.

According to the 2025 CAQH Index, healthcare has a $21 billion savings opportunity through full automation of manual and partially manual transactions — and despite a major cyberattack disrupting healthcare in 2024, the industry still avoided $258 billion in administrative costs by leaning on digital infrastructure. That's proof the shift to digital pays off, especially under pressure.

Digital Isn't Risk-Free — But It's Defensible

Shifting to digital payments doesn't eliminate fraud. It changes the nature of it. Digital fraud concentrates on specific, predictable weaknesses: weak onboarding, compromised credentials, and authentication gaps on high-risk actions like banking changes or payment initiation.

Predictable weaknesses are addressable, and that's what makes a fraud-resilient payment program valuable.

What a Fraud-Resilient Payment Program Requires

Fraud resilience isn't a single tool or a new policy. It's a coordinated set of capabilities working together:

• Unified payment infrastructure brings workflows into a single environment, so irregular patterns surface earlier and authentication gaps close.
• Continuous identity and account verification ensures payments reach the right entity not just at enrollment, but every time account details change.
• Real-time monitoring and behavioral analytics catch suspicious activity as it forms, not after funds have cleared.
• Secure digital payment options (ACH, real-time payments, card-based disbursements) operate within traceable, controllable environments that paper simply cannot match.

None of these work in isolation. When they work together, fraud has far fewer places to hide.

Technology drives these capabilities, but human judgment remains essential. Experienced fraud analysts provide the context that automated systems can't fully replicate. Automation and expertise together are what turn detection into defense.

Fraud Costs More Than Money

Payment fraud damages more than balance sheets. It erodes the trust that provider relationships and member experience depend on.

The numbers reflect it. A PYMNTS Intelligence report found 48% of organizations report lost business opportunities after a fraud incident and 44% cite lasting reputational damage.

In healthcare and P&C, where payment accuracy directly shapes how providers, members, and claimants experience the organization, those effects compound quickly. Trust, once lost, isn’t guaranteed to return.

The Question Isn't Whether to Modernize

Fraudsters don't usually win because they're more sophisticated. They win because they adapt faster than the defenses built to stop them.

This gap — not any single tactic — is what creates sustained risk for finance leaders in healthcare and P&C.

The question is no longer whether you can afford to modernize your payment infrastructure. It's whether you can afford not to.
